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. Here's a quick update on our progress! ::More about this Video:: ► Teachey & Kipping (2017), "HEK VI: On the Dearth of Galilean Analogs in Kepler and the Exomoon Candidate Kepler-1625b I": https://arxiv.org/abs/1707.08563 ► Alex's SciAm blog article: https://blogs.scientificamerican.com/observations/are-astronomers-on-the-verge-of-finding-an-exomoon/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+sciam%2Fspace+%28Topic%3A+Space%29 ► 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!!
