NASA has announced the discovery of 7 Earth-like exoplanets 13 hours ago. What are the chances of life there? Is it possible to see the ground of these planets from here? How far are they?
NASA has said roughly Earth sized. From this, reporters have written "Earth like". Some publications are even showing what look like photos of planets. These are likely generated with computers used for creating planets in games and films.
As for life, we only know of one planet that developed life, and you can't build a statistical model from that. Searching for life could be a complete waste of time.
