The Cool Worlds Lab just announced the discovery of the first transiting Jupiter-analog outside the Solar System, named "Kepler-167e". The transit method has been incredibly successful at finding exoplanets, with thousands now known thanks to NASA's Kepler Mission. But, planets on wide orbits, like Jupiter, are very tricky to find with this technique. Prof Kipping explains how his team overcame these obstacles to make this important discovery, opening the door to learning about alien Jupiters in much more detail. ::More about this Video:: ► Kipping et al.

How common are planets like the Earth around other stars? This is a question humanity has been asking since the dawn of civilization, ultimately feeding into the question as to whether we are alone in the Universe? Astronomers are on a quest to calculate "eta-Earth", the fraction of stars hosting Earth-like planets. Thanks to NASA's Kepler Mission, we have recently begun to answer this question. Prof Kipping gives a quick run down of the latest estimates. ::More about this Video:: ► NASA's Kepler Mission homepage: https://kepler.nasa.gov ► Foreman-Mackey et al.

Is there a way to naturally classify the different types of planets in the Universe? Two of the most fundamental properties of any object are its mass and size and generally one expects size to increase as we add more mass. The relationship between size and mass itself changes though at certain points, and this offers a clear way to classify worlds. Graduate student Jingjing Chen of the Cool Worlds Lab discusses one component of her new paper which does just this, classifying planets based off their mass and size and concluding that just four broad categories of planets explain the data. ::More about this Video:: ► Chen & Kipping (2016), "Probabilistic Forecasting of the Masses and Radii of Other Worlds": http://arxiv.org/abs/1603.08614 ► "Forecaster" open-source software package: https://github.com/chenjj2/forecaster ► Outro music by Taylor Davis: https://www.youtube.com/watch?v=dl9kI1yQKZk ::Playlists For Channel:: Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorlds Cool Worlds Research ► http://bit.ly/CoolWorldsResearch Guest Videos ► http://bit.ly/CoolWorldsGuests Q&A Videos ► http://bit.ly/CoolWorldsQA Science of TV/Film ► http://bit.ly/ScienceMovies ::Follow us:: SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribe Cool Worlds Lab http://coolworlds.astro.columbia.edu Twitter https://twitter.com/david_kipping Instagram https://www.instagram.com/cool.worlds THANKS FOR WATCHING!!

This week's guest video comes from Prof Catherine Espaillat from Boston University who came by the Cool Worlds Lab to talk about planet formation. Astronomers have been seeing disks of material around young stars, and even gaps in those disks implicating planets sweeping up the matter.

Does life's early emergence mean life starts easily? Growing evidence shows that life got started very quickly (within ~100 million years) after conditions became suitable for life on Earth (~3.7 billion years ago). This is often taken as evidence that life starts easily, but is this really true?

We're looking forward to the new sci-fi film "Arrival", which explores the barriers to communicating with aliens even face to face. Astronomers really are trying to listen for alien communications, mostly using radio receivers but increasingly by looking for optical laser transmissions too. One of our wild ideas here at the Cool Worlds Lab is that optical SETI could try focussing these efforts to physically-motivated special moments in time to dramatically increase the survey efficiency.

As regular watchers of the channel may remember, this summer astronomers announced the discovery of a potentially Earth-like planet orbiting our nearest star, Proxima Centauri. Sadly, research at the Cool Worlds Lab was unable to find any evidence that Proxima b transits its star, which is a blow for those hoping for near-term characterization of its atmosphere. But!

Organic molecules are essential for life. The Earth and the Solar Systems appears to have plenty but do planets around other stars have them as well? Planets still in the process of forming are usually accompanied by disks of left-over material and using the ALMA telescope we have started to probe the chemistry of these alien systems! Karin Öberg, a professor of astrochemisty, explains what we've learnt about extrasolar organic molecules so far.

When will our civilization end? Whether it be by our own means or an external threat, there are many plausible scenarios which could extinguish humanity.

Yes, the question of what makes a planet a "planet" is back in the news after a team of planetary scientists published a new paper challenging the status quo and arguing that Pluto should be a planet again.

Earth-sized planets found in the habitable-zones of low-mass stars are likely to become tidally locked to the star, with one side baked in perpetual sunlight and other trapped in an eternal night. These so-called "Eyeball Earths" turn out to be extremely common and some famous examples include Proxima b and the planets around TRAPPIST-1.

New research paper from the Cool Worlds Lab about one the most exciting missions ever proposed, "Starshot". Starshot plans to send tiny probes to distant planets beyond our Solar System, the first true interstellar spacecraft. To do this within our lifetimes requires a very fast probe, reaching one-fifth the speed of light.

Jupiter is the King of the Solar System but exoplanet surveys have revealed that it's an unusual type of world. Just ~10% of Sun-like stars have planets of the same mass and orbit as Jupiter. So could the existence of Jupiter be somehow beneficial to emergence of complex life, like us, on other planets in the system? On the hand, maybe Jupiter's strong gravity should scatter asteroids towards us, perhaps making things worse?

Breakthrough Starshot plans to accelerate a gram-mass spacecraft up to one-fifth the speed of light to reach nearby stars in our lifetimes. In a recent video (https://youtu.be/Ksb6Vh0BT_E), I discussed some work I'd taken on calculating how the speed of the spacecraft (a light sail) changes as one shines an intense laser beam on it. It turns out my equations differ with the predictions of the Breakthrough team, and indeed just about everyone whose worked on this problem all the way to Einstein himself, who treated it as an example calculation for relativity. Remarkably, there does appear to be a small mistake in this example calculation (but not relativity itself) and in this video I explain how I came across it, why I'm convinced it's right and the nature of serendipitous discovery. ::More about this Video:: ► The paper (now accepted for publication) is available here- David Kipping (2017), "Relativistic Light Sails": https://arxiv.org/abs/1704.04310 ► Asst Prof David Kipping homepage: www.davidkipping.com ► Philip Lubin (2016), "A Roadmap to Interstellar Flight": https://arxiv.org/abs/1604.01356 ► Kulkarni, Lubin & Zhang (2016), "Relativistic solutions to directed energy": http://proceedings.spiedigitallibrary.org/proceeding.aspx?articleid=2555764 ► Arthur Compton (1923), "A Quantum Theory of the Scattering of X-rays by Light Elements": https://journals.aps.org/pr/abstract/10.1103/PhysRev.21.483 ► Albert Einstein (1905), "Zur Elektrodynamik bewegter Körper": http://onlinelibrary.wiley.com/doi/10.1002/andp.19053221004/abstract ► Breakthrough Initiatives website: https://breakthroughinitiatives.org ► Cool Worlds Lab website: http://coolworlds.astro.columbia.edu ► Columbia University Department of Astronomy: http://www.astro.columbia.edu ► Background music by MelodySheep "Secrets of the Stars": https://www.youtube.com/watch?v=BuxFXHircaI ::Playlists For Channel:: Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorlds Cool Worlds Research ► http

We now know of thousands of exoplanet candidates discovered by NASA's Kepler Mission, using the so-called transit method. Unfortunately, transits only tell astronomers the size of the planet, not the mass. Cool Worlds Lab member Jingjing Chen discusses her new research paper which applies a type of forecasting model to predict planetary masses, based off their sizes. This reveals a couple of strange observations, as Jingjing explains in this video. ::More about this Video:: ► Chen & Kipping (2017b), "Forecasted masses for seven thousand KOIs": https://arxiv.org/abs/1706.01522 ► Chen & Kipping (2017a), "Probabilistic Forecasting of the Masses and Radii of Other Worlds": https://arxiv.org/abs/1603.08614 ► Cool Worlds - Classifying Worlds: https://www.youtube.com/watch?v=sp28ZN9Zhdw ► Cool Worlds Lab website: http://coolworlds.astro.columbia.edu ► Columbia University Department of Astronomy: http://www.astro.columbia.edu ► Background music by Thomas Bergersen "Final Frontier": http://www.thomasbergersen.com ::Playlists For Channel:: Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorlds Cool Worlds Research ► http://bit.ly/CoolWorldsResearch Guest Videos ► http://bit.ly/CoolWorldsGuests Q&A Videos ► http://bit.ly/CoolWorldsQA Tabby's Star ► http://bit.ly/TabbysStar Science of TV/Film ► http://bit.ly/ScienceMovies ::Follow us:: SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribe Cool Worlds Lab http://coolworlds.astro.columbia.edu Twitter https://twitter.com/david_kipping Instagram https://www.instagram.com/cool.worlds THANKS FOR WATCHING!!

After discovering thousands of planetary systems orbiting other stars, we are finally at a point where we can start looking at the patterns we see to hopefully understand how they formed. But hold the phone - because maybe the configurations we see are nothing but purely random. Dynamical evolution tends to disorder initially pristine systems, so do planets even still remember how they formed? Is the ordered nature of the Solar System typical or rare? This week we dive into these questions by discussing a new research paper by Prof Kipping on the topic. ::More about this Video:: ► Kipping (2017), "Do planets remember how they formed?": https://arxiv.org/abs/1709.04987 ► GitHub repo of the microstate visualizations: https://github.com/CoolWorlds/exoinformatics ► Cake number: https://en.wikipedia.org/wiki/Cake_number ► Eulerian number: https://en.wikipedia.org/wiki/Eulerian_number ► Kepler Orrey by Dan Fabrycky: http://astro.uchicago.edu/~fabrycky/kepler/ ► Columbia University Department of Astronomy: http://www.astro.columbia.edu ► Cool Worlds Lab website: http://coolworlds.astro.columbia.edu ► Outro music by 8-bit Universe "Harder Better Faster Stronger [8 Bit Cover Tribute to Daft Punk]": https://8bituniverse.bandcamp.com/track/harder-better-faster-stronger-8-bit-tribute-to-daft-punk ::Playlists For Channel:: Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorlds Cool Worlds Research ► http://bit.ly/CoolWorldsResearch Guest Videos ► http://bit.ly/CoolWorldsGuests Q&A Videos ► http://bit.ly/CoolWorldsQA Tabby's Star ► http://bit.ly/TabbysStar Science of TV/Film ► http://bit.ly/ScienceMovies ::Follow us:: SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribe Cool Worlds Lab http://coolworlds.astro.columbia.edu Twitter https://twitter.com/david_kipping Instagram https://www.instagram.com/cool.worlds THANKS FOR WATCHING!!

New research freshly baked from the Cool Worlds Lab! Emily Sandford's new paper shows how we can actually use planets to learn about the stars they go around in an important new piece of work. When we use planets to learn about stars, we call them "stellar anchors", since they lock down the stellar properties. This flips a classic mantra on it's head, know the star know the planet becomes know the planet know the star.

In 2016, Konstantin Batygin and Mike Brown shook up the field of planetary science when they proposed an additional planet in the outer Solar Sytsem: "Planet Nine".

Konstantin swung by the Cool Worlds Lab this week to tell us about his most recent work on Planet Nine and the latest from observational search efforts. ::More about this Video:: ► Konstantin Batygin Twitter: @kbatygin ► Konstantin Batygin personal website: https://www.konstantinbatygin.com ► Konstantin Batygin & Alessandro Morbidelli 2017, "Dynamical Evolution Induced by Planet Nine", AJ accepted: https://arxiv.org/abs/1710.01804 ► Konstantin Batygin & Michael Brown 2016, "Evidence for a Distant Giant Planet in the Solar System", AJ, 151, 22: https://arxiv.org/abs/1601.05438 ► Michael Brown & Konstantin Batygin 2016, "Observational constraints on the orbit and location of Planet Nine in the outer solar system", ApJ, 824, 23: https://arxiv.org/abs/1603.05712 ► Matthew Holman & Matthew Payne 2016, "Observational Constraints on Planet Nine: Cassini Range Observations", AJ, 152, 94: https://arxiv.org/abs/1604.03180 ► Benjamin Bromley & Scott Kenyon 2016, "Making Planet Nine: A Scattered Giant in the Outer Solar System", ApJ, 826, 64: https://arxiv.org/abs/1603.08010 ► Scott Kenyon & Benjamin Bromley 2016, "Making Planet Nine: Pebble Accretion at 250--750 AU in a Gravitationally Unstable Ring", ApJ, 825, 33: https://arxiv.org/abs/1603.08008 ► Columbia University Department of Astronomy: http://www.astro.columbia.edu ► Cool Worlds Lab website: http://coolworlds.astro.columbia.edu ► Outro music by 8-bit Universe "Harder Better Faster Stronger [8 Bit Cover Tribute to Daft Punk]": https://8bituniverse.bandcamp.com/track/harder-better-faster-stronger-8-bit-tribute-to-daft-punk ::Playlists For Channel:: Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorlds Cool Worlds Research
Earlier this year we found our most compelling exomoon candidate to date, Kepler-1625b-i. Although the signal of what would be the first exomoon looked pretty good, we remain skeptical about the reality of the object given that we only saw three transits during the entire four years of Kepler. You might recall we applied for some Hubble Space Telescope time, which we have been busy analyzing for the last couple of months.

Tabby's Star (aka Boyajian's Star) is back in the news with some new data published by the original discoverers. Finally we are starting to get a sense as to what might be going on around this star, with dust emerging as a leading hypothesis. Is the alien megastucture hypothesis excluded now? Where did the dust come from? How can we confirm this idea?

We've been looking forward to sharing this one with you... Last year, we started thinking about what it would take to detect mountains, valleys and volcanoes - surface topography - on an exoplanet. It seemed like a crazy idea at the time but we decided to make the calculation for fun and were surprised that it may actually be feasible in the not too distant future. Moiya McTier of the Cool Worlds Lab explains how we started thinking about this and our novel method for attempting to detect such features.

At best, we typically only know the mass and radius of exoplanets. But really, when we find rocky planets we'd like to know whether their interiors are similar or dissimilar to that of the Earth. Conventionally, this is impossible, as there are simply too many possible models and just two measured quantities. In a new research paper from our group, the Cool Worlds Lab here at Columbia University, we think we've helped crack at least part of the problem. Our new model, called HARDCORE, is explained in this video by the lead author and rising senior undergraduate at Columbia, Gabrielle Suissa - enjoy! ::More about this Video:: ► Suissa & Kipping (2018), "A HARDCORE model for constraining an exoplanet's core size", MNRAS, 476, 2613: https://arxiv.org/abs/1804.02019 ► HARDCORE code is available at GitHub: https://github.com/gsuissa/hardCORE ► Columbia University Department of Astronomy: http://www.astro.columbia.edu ► Cool Worlds Lab website: http://coolworlds.astro.columbia.edu ► Outro music by 8-bit Universe "Harder Better Faster Stronger [8 Bit Cover Tribute to Daft Punk]": https://8bituniverse.bandcamp.com/track/harder-better-faster-stronger-8-bit-tribute-to-daft-punk ::Playlists For Channel:: Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorlds Cool Worlds Research ► http://bit.ly/CoolWorldsResearch Guest Videos ► http://bit.ly/CoolWorldsGuests Q&A Videos ► http://bit.ly/CoolWorldsQA Tabby's Star ► http://bit.ly/TabbysStar Science of TV/Film ► http://bit.ly/ScienceMovies ::Follow us:: SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribe Cool Worlds Lab http://coolworlds.astro.columbia.edu Twitter https://twitter.com/david_kipping Instagram https://www.instagram.com/cool.worlds THANKS FOR WATCHING!!
The Search for Extraterrestrial Intelligence (SETI) has been growing in confidence and repute lately thanks to astronomer's detections of habitable worlds and the private funding been poured into the enterprise. With renewed efforts afoot, it's worth pausing for a moment and asking - well what do we do if we succeed? How should the scientists communicate their results? How will the public react? Social media in particular disrupts the conventional pattern of scientific announcements and poses some interesting challenges for SETI.

TRAPPIST-1 is an amazing system discovered last year featuring seven roughly Earth-sized planets all transiting their diminutive parent star. Could there be an eighth? If there is, in this video Prof Kipping argues that it should be possible to precisely predict what the orbital period of such a planet would be.

The Kardashev Scale has become a standardized way of classifying (hypothetical) advanced civilizations. The lowest rank, Type 1, is still way ahead of us - but by how much? When will we achieve Type 1 status and exactly how could we plausibly do so?

We know of thousands of planets but precisely zero around white dwarfs. White dwarfs are not weird unusual objects but the inevitable fate of over 90% of the stars in our Universe - including the Sun! They're so small and faint that no telescope, even Kepler, has been able to find planets yet. But a new telescope - called LSST - might change all that. Jorge Cortés, a graduate student here at Columbia in the Cool Worlds Lab, tells us today about his new paper where he calculates how feasible it would be for LSST to pull off this last great planet detection trick which has evaded us to date! ► Jorge Cortés & David Kipping (2018), "On the detectability of transiting planets orbiting white dwarfs using LSST", MNRAS, submitted: https://arxiv.org/abs/1810.00776 ► Sarah Ballard Cool Worlds video on polluted white dwarfs: https://youtu.be/MAeqIQd6BMM ► Keith Hawkins Cool Worlds video on stellar evolution: https://youtu.be/rPmekP6B9Rw ► Background music by 1) Atlas "Waking Up" 2) Ryan Stubbs "Through Reborn Eyes - Unfiltered".

Transits. We all love them. Right now, we know of over four thousand exoplanets which transit their star and these transits teach us a lot about distant worlds. NASA's TESS mission is just getting started, looking to find even more transits! But TESS has a problem when it comes to long-period planets, because it only looks at most fields for a month - meaning sometimes it will see just a single transit of a planet. This makes it very tricky to determine the period and all sorts of biases affect our inference, as we explore in today's video! ► Kipping (2018), "The Orbital Period Prior for Single Transits", RNAAS, submitted: https://github.com/davidkipping/singletransits/blob/master/rnaas.pdf ► Our previous episode about TESS: https://youtu.be/-2SECBi-AP8 ► NASA TESS Mission Website: https://heasarc.gsfc.nasa.gov/docs/tess/ ► Villanova et al.

Boyajian's Star (Tabby's Star) has mystified us since we first saw those bizarre dimmings recored by NASA's Kepler Mission. Over the years, people have shown that the data could be explained by comets, or planet engulfement, or even alien megastructures. But here at the Cool Worlds Lab, we had a different idea. Rather than propose a specific hypothesis and see how well it matches the data, why not use the data to reconstruct an image of whatever it was that caused the dimming? Sounds simple, right?

How could we one day travel between the stars with real physics? Perhaps the greatest challenge to interstellar flight is energetics - it takes vast amounts of energy to accelerate even small ships to 20% the speed of light.

Could humans ever travel to other galaxies within their lifetime? The immense scale of the Universe seems to prohibit such voyages, after all the nearest galaxy is so far away that it takes light itself - the fastest thing in the Universe - 2.5 million years to complete the trip. Remarkably, there is a trick that might allow humans to accomplish this feat - join us today as we step onboard the constantly accelerating spaceship!

We now have around 5000 satellites in orbit of the Earth and all of them are compelled to follow orbital paths dictated by Johannes Kepler's Laws of Planetary Motion, first written down in the early 17th century. Could there be a way to hack the orbital physics and break away from Kepler's Laws? Today we'll explore a novel space technology called statites, and a twist on it we're calling quasites, that could very well do exactly this.

The Solar System is an eight-planet system - but is that typical of other stars too? How often do other stars have 8 planets? Or is some other number more common? Put another way, what is the multiplicity distribution of exoplanets? This is a devilishly difficult problem to unlock because our telescopes provide incomplete views of distant stars, what about the missing planets? In new research here from the Cool Worlds Lab, we show how progress can be made by hypothesizing a family of various distributions, simulating the resulting planets and expected planet detections, and then comparing to reality. Although current techniques only reveal planets on periods less than 400 days, this still gives us a chance to quantify the multiplicity of the inner part of exoplanetary systems!

When it comes to telescopes, bigger is better. That's why we're investing billions of dollars into a new generation of "extremely large telescopes", such as the Thirty Meter Telescope (TMT). But is 30 meters truly extreme? Could it be possible to ever build a telescope on the scale of a planet? In a new research paper by our very own Professor David Kipping, a solution for turning the Earth into a "Terrascope" is presented. Join us on a journey though the history of telescope inventions as well David's own personal journey to devising this new radical approach to the telescope.

Planets, like the Earth, could potentially serve as giant telescopes - as explored in our last video (https://youtu.be/jgOTZe07eHA). This happens because the atmosphere refracts light and so bends it into a focus, like a huge spherical lens. Parabolic dishes on Earth can be sued as both telescopes and antennae, and so in the same way - could planets be used as antennae? Today we explore the possibility of using the Jupiter as a giant antennae, perhaps serving as the basis for an interplanetary internet, and how Juno could very well test the idea today.

Over recent years, newspapers have been filled with headlines such as "billions of Earths in the Milky Way alone". But how many Earth-like planets are there really? Join us as we explore all of the different estimates for how many Earths there really are, how each team arrived at their answers, and why they seem to differ so wildy from each other, before finally we'll offer our own answer to this monumental question.

In the last few decades, our astronomical techniques have developed to the point that we can now detect planets orbiting other stars. Planets which transit their star make up most of our catalogs, because they are so easy to find and can reveal so much more information about the planets. For example, in the near future we might even be able to detect life remotely on these worlds. This makes us wonder - could someone out there already be using this method on us? Here, we explore which stars are best placed to detect us using the transit method, what they might learn about us and the possibility of reciprocal transit configurations, enabling a possible means of direct communication across the stars.

Black holes are one of the most bizarre and terrifying results from general relativity - a singularity of infinite density from which even light cannot escape. Black holes fascinate us and this has led some to wonder if the could even be used as a power source. Micro black holes, that is black holes much lighter than a star, could be one of way of doing this. Today we explore the possibilities of a micro black hole and exactly how it might be possible to turn them into power banks. Written and Presented by Prof. David Kipping.

Many of us dream of a future for humanity in space, a civilization spanning multiple worlds and perhaps one day even star systems. But even with reusable rockets, the expense of lifting huge structures into orbit truncates our vision. Space elevators have long held promise as a possible solution, but the need for incredibly strong materials has made them a distant prospect. Today, Cool Worlds graduate student (soon to be postdoc!) Emily Sandford describes an alternative but related concept - the lunar space elevator. With no obvious technological hurdles preventing it's construction, this could be realized in our lifetimes - either for good, or for bad... Written and Presented by Emily Sandford.

What does the future hold for humanity and our changing climate in the 21st century? Using projections from the IPCC Fifth Report and the climate science literature, we've put together a timelapse showing what may lie ahead. On the left hand side of the screen you'll see an "optimistic" view, where although we continue to emit carbon dioxide at significant levels, investments in clean energy and mitigation try to curb the damage. On the right hand side, you'll see a future where humanity emits as much as we please and very little mitigation takes place. The data presented in this video are a projection of the 21st century. We used two of the Representative Concentration Pathways (RCP), presented in the IPCC Fifth Report, as plausible scenarios - although these are not strictly forecasts. Seasonal variations were added using a stochastic generator conditioned upon observed seasonal variability reported by NASA GISS. Similarly, seasonal variability in carbon dioxide levels were simulated based on historical seasonal variations about a moving average predicted using the RCP models. Special thanks to Gavin Schmidt for advice during the course of this video production. And sorry for the typo at the very end! *It’s!!!

30 years ago, on 14th February 1990, Voyager 1 captured an iconic image of the Earth - known as the "Pale Blue Dot". This photo was taken from a staggering 6 billion kilometers away - at the edge of the outer Solar System. Taken at the request of legendary astronomer Professor Carl Sagan, Sagan waxed poetically about the image a speech often referred to as the "Pale Blue Dot". To celebrate the 30th anniversary of this truly unique image, NASA and JPL-Caltech reprocessed the original image using modern processing techniques. In honor of the Voyager 1 team and the late Carl Sagan, we put together this short tribute video celebrating the Pale Blue Dot, with a reading of Sagan's wonderful prose by Professor David Kipping.

At the beginning of 2020, the world held its collective breath as a nearby behemoth star, called Betelgeuse, start to dramatically fade. Could this mean the star is about to go supernova? With the recent flutter of news activity settling down, we are now finally starting to understand what might have really happened. Today, we take a deep dive into what makes massive stars like this tick, and then get into how we might have now finally come up with answers to this bizarre event.

I think we all need a break from the coronavirus news barrage! So to take our minds off things, I (Prof David Kipping) will host a little live stream Q&A Hangouts session on Sunday night. Happy to field any questions you have about our previous videos, research happening in my team, or just general astro/planet questions (as best I can!). Join us live and feel free to get your questions in early down in the comments.
Have you ever wondered if there’s a Galactic Empire out there? How long would it take a space faring civilization to colonize the entire galaxy? Remarkably even traveling at sub-light speeds this should be possible within a fraction of our galaxy’s lifetime. Which raises the question - why hasn’t this happened yet? Today we dive into the repercussions of “Fact A” - the simple observation that Earth has not been colonized by an alien civilization. I sit down with Prof. Jason Wright who has recently co-authored a new paper that provides the most sophisticated treatment to date of this problem, and what it means for our place in the Universe.

Why haven't we found dozens of exomoons yet? With planets as small as the Moon having been detected by NASA's Kepler Mission, it's fair to wonder why we only know of a single exomoon candidate to date. Despite the lack of moon detections, there are actually hundreds of known planets that wobble around, a tell-tale sign that a moon could be present. Unfortunately, these wobbles can also be caused by other planets and so in a new research appear Prof Kipping and Alex Teachey have re-visited the theory behind exomoons and come up with a new trick to help us discern between the two - impossible moons.

If we re-ran Earth's clock, would life arise again? Would another civilization eventually evolve? Astrobiology is faced with trying to contextualize our place in the Universe using just a single data point. But even a single data point contains information. The key to unlocking it is a careful understanding of the selection biases at play and intricacies of Bayesian statistics. Today, we're thrilled to present to you our explainer video of a new research paper led by Prof David Kipping that provides a direct quantification of the odds of life and intelligence on Earth-like worlds, based on our own chronology.

The Copernican Principle has been with us for centuries. It broadly states that "we are typical" but increasingly we are beginning to question this doctrine. One famous push back is the Rare Earth hypothesis, but testing this idea will take generations. What about our Sun? Surely here we should have a better understanding as to whether our star is typical or not. Join us as we discuss why the Sun might be more special than Copernicus ever imagined.

Have you ever have a dream you were so sure was real? The simulation argument challenges our very notions of reality by asking whether everything we perceive is nothing more than an elaborate computer simulation. Recently, we've even seen headlines like "one in a billion" probability that we live in the real world. Could this be right? How does this affect how we think about our lives? And are there any counter-arguments to save us? New research from the Cool Worlds Lab resolves.

The announcement of the detection of a possible biomarker in the atmosphere of Venus has shook up the field of astrobiology and grabbed headlines across the world. Today, we explore why Venus could plausibly host life, how this detection was made, and whether it really means that we've finally found extraterrestrial life.

Are alien civilizations likely to be younger or older than us in age? A basic question that seems insurmountable until we start detecting them.

Exomoons represent an oustanding challenge in modern astronomy. The quest for their detection has been a topic central to Cool Worlds' mission and methods developed a decade ago have largely guided that effort. But after years of trying, we have been revisiting these methods and have an exciting breakthrough to share with you all - a new hope for finding exomoons.

Three years ago, we detected the first interstellar object passing through the Solar System, `Oumuamua. Ever since, astronomers have been debating the origins of this strange body. Whilst many hypothesize an asteroid, the media is ablaze with the possibility that it could be alien technology. Join us today for a discussion of this theory and the counter-arguments proposed.

A century ago, many thought Mars was scored by a canal system constructed by an advanced civilization - an idea championed by astronomer Percival Lowell. Why? How did an astronomer come to this conclusion? Today we explore the canal phenomenon and discuss why it's a crucial allegory from history - pertinent now more than ever.

Sixty years ago Frank Drake wrote down an equation that has become one of the most famous in astronomy - the Drake Equation. This formula, aiming to estimate the number of alien civilizations communicating within the galaxy, has been celebrated, abused and criticized. Today, we are taking a deep dive into this special equation in a two part special. Written and presented by Prof David Kipping. Thanks to Jason Wright and Nadia Drake for help with this video.

Visit our sponsor, Brilliant.org: https://brilliant.org/CoolWorlds. Astronomers are on a quest to search for life in the Universe. Two different pathways lay ahead for this hunt, biosignatures and technosignatures. Today, we discuss the arguments for and against each and consider that intelligence could be a far more persistent phenomenon that we might naively think - with important consequences for astronomers...

Visit our sponsor, Brilliant.org: https://brilliant.org/CoolWorlds The cosmos is littered with blue and red stars... but curiously no green ones. Why? Is this a fundamental constraint or merely an unlikely outcome? And what would it mean for humanity if we ever did detect a green star? Join us today as we explore this simple question with major implications.

And now time for something completely different. This week I was interviewed for the science documentary show "How the Universe Works" and I decided to film some time lapses of the shooting and give you a little insight into this rather different way of communicating science to our regular style on Cool Worlds. I have no idea when this will air - probably many months away! ::More about this Video:: ► Pioneer TV, "How the Universe Works": http://www.pioneertv.com/programmes/how-the-universe-works-5/ ► Cool Worlds Lab website: http://coolworlds.astro.columbia.edu ► Columbia University Department of Astronomy: http://www.astro.columbia.edu ► Background music by David Cutter Music: https://dcuttermusic.bandcamp.com ► Outro music by Daft Punk "Harder, Better, Stronger, Faster": http://www.daftpunk.com and http://smarturl.it/DaftPunkiTunes ::Playlists For Channel:: Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorlds Cool Worlds Research ► http://bit.ly/CoolWorldsResearch Guest Videos ► http://bit.ly/CoolWorldsGuests Q&A Videos ► http://bit.ly/CoolWorldsQA Tabby's Star ► http://bit.ly/TabbysStar Science of TV/Film ► http://bit.ly/ScienceMovies ::Follow us:: SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribe Cool Worlds Lab http://coolworlds.astro.columbia.edu Twitter https://twitter.com/david_kipping Instagram https://www.instagram.com/cool.worlds THANKS FOR WATCHING!!
