Astronomers believe that Earth-like planets could be all around us, and some may even harbour life that would be much older and more evolved than on Earth.
Astronomers have discovered a new super-earth in the habitable zone around the red dwarf star Gliese 163.
Using the United Kingdom Infrared Telescope on Hawaii, a team of astronomers have discovered four pairs of stars that orbit each other in less than 4 hours.
Scientists say tides may dry out what would otherwise be habitable planets around small stars, making them hostile to life.
