![]() The two other suns would look like a pair of very bright stars visible in the daytime and at night they would provide as much illumination as the full Moon. These planets orbit the third faintest star of a triple star system. Keck Observatory and the Magellan Telescope to find evidence for up to seven planets around the star. Now, a team of astronomers has reexamined the system by re-mining existing European Southern Observatory’s HARPS data and combining it with data collected from the W. Previous studies of the triple star system called Gliese 667C showed the star hosts three planets with one of them in the habitable zone. The findings will be published in the journal Astronomy & Astrophysics on June 26. This is the first system found with a fully-packed habitable zone. More importantly, three of those planets are super-Earths, lying in the Goldilocks Zone where liquid water could exist, making them possible candidates for the presence of life. Kamuela, HI - A team of scientists recently confirmed six, and possibly seven, planets orbiting a star system a mere 22 light-years from Earth. Two of the planet candidates lie within this extended definition of the habitable zone. ![]() In them a planet might still be able to support liquid water on its surface if more exotic atmospheric compositions are allowed. The red and blue bands indicate the hot and cold edges of such habitable zone. ![]() ANIMATION: Three of the planets around Gliese 667C orbit within its habitable zone (in green) where a planet with Earth-like conditions would be habitable.
