The universe's best real estate for life may be around stars a little less massive than the sun, called orange dwarfs, according to a new analysis. These stars live much longer than sun-like stars, and have safer habitable zones - where liquid water can exist - than those of lighter red dwarf stars. Stars similar in mass to the sun, categorised as a yellow dwarf, have received the most attention from planet hunters. But recent research suggests orange dwarfs may provide an even better hunting ground for life-bearing planets.
