Astronomers have discovered what they say is the most Earth-like planet yet detected — a distant, rocky world that’s similar in size to our own and exists in the Goldilocks zone where it’s not too hot and not too cold for life.
The find, announced Thursday, excited planet hunters who have been scouring the Milky Way galaxy for years for potentially habitable places outside our solar system.
“This is the best case for a habitable planet yet found. The results are absolutely rock solid,” University of California, Berkeley astronomer Geoff Marcy, who had no role in the discovery, said in an email.

Habitable alien planets similar to Earth may not be that rare in the universe, a new study suggests.
About one in five sunlike stars observed by NASA’s planet-hunting Kepler spacecraft has an Earth-size planet in the so-called habitable zone, where liquid water — and, potentially life — could exist, according to the new study. If these results apply elsewhere in the galaxy, the nearest such planet could be just 12 light-years away.
“Human beings have been looking at the stars for thousands of years,” said study researcher Erik Petigura, a graduate student at the University of California, Berkeley (UC Berkeley). “How many of those stars have planets that are in some way like Earth? We’re very excited today to start to answer that question,” Petigura told SPACE.com. [9 Exoplanets That Could Host Alien Life]

A sun-like star in our solar system’s backyard may host five planets, including one perhaps capable of supporting life as we know it, a new study reports.
Astronomers have detected five possible alien planets circling the star Tau Ceti, which is less than 12 light-years from Earth — a mere stone’s throw in the cosmic scheme of things. One of the newfound worlds appears to orbit in Tau Ceti’s habitable zone, a range of distances from a star where liquid water can exist on a planet’s surface.
With a minimum mass just 4.3 times that of Earth, this potential planet would be the smallest yet found in the habitable zone of a sun-like star if it’s confirmed, researchers said.
