New Star in the Universe

Another habitable planet has been found - this one around a star just like our Sun! The star in question is Tau Ceti - visible with the naked eye - which has five planets orbiting it (an artist's impression of the system is shown here). The potentially habitable planet is about five times the mass of Earth, making it the smallest planet we've found in the habitable zone of a Sun-like star.
