One of the most fascinating areas of astronomical research in recent years has been the search for other ‘Earths’ circling Sun-like stars far beyond our Solar System.
In recent years nearly 100 planets have been discovered in orbits around other stars, but none of these ‘exoplanets’ remotely resembles the Earth.

However, according to the latest computer simulations by Barrie Jones and Nick Sleep (The Open University), millions of Earthlike worlds could be scattered throughout the Galaxy, just waiting for telescopes to improve sufficiently for us to find them.
