Discovering Other Earths
We have found over 700 planets orbiting other stars and life forms on Earth that might survive on these alien worlds. The X-Planets visits the most famous of these exoplanets and explores 3D artists’ renderings of each planet’s surface. These are alien worlds around other suns where we are looking for life today – rocky worlds with comfortable temperatures and maybe liquid water. Some have two or three suns. But how do we see these worlds and know what their surfaces are like? Answering that question is also part of The X-Planets show.
