We don’t know why Earth is so special. Marcus Chown doesn’t think it is: he expects that soon enough we will find life elsewhere in the universe.
In this video interview, Marcus describes how he would build a telescope that can image a second Earth. Last year saw the discovery of planets within the habitable zones of their solar systems. Could this decade be the one in which we can build a telescope sensitive enough to take a peek at them?
Marcus Chown is an award-winning writer and broadcaster, currently the cosmology consultant for New Scientist magazine.
