In the series opener, Hubble takes us on a journey through the cosmos, showing us planetary nebulae which are composed of puffs of gas that is expelled and illuminated by the stars it houses. Along with this they are home to galaxies that have dust and molecules that will become stars in the future.
With light a necessity, we are taken through how light is emitted, absorbed, the effects gravity has on light and how it chnages our view, and how it is reflected by gas and dust particles to the nebulae and galaxies we see today. With these factors, we are able to see some of the most beautiful nebulae out there.
From thinking that the earth was the center of the universe to the earth is flat, we have come along way to realizing whats true and that the universe is of infinite space. From our galaxy to the furthest reaches of space, Hubble takes us to unimagined places and takes us back in time to when the universe was.
