Call it the comeback of the year.

Last year, equipment failure caused NASA to deem its $600-million Kepler space telescope irreparable. But since then, astronomers and engineers devised an ingenious way to repurpose Kepler, whose mission has been to scour the cosmos in search of Earthlike planets.

And now, the planet-hunting probe not only has been reborn, but also has discovered a massive exoplanet some 180 light-years away.

Newfound Earth-Like Planet, Kepler-186f, Is ‘Best Case’ For Hosting Life, Astronomers Say

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.

Earth-Like Habitable Planets Surprisingly Common, Kepler Space Telescope Data Suggest (VIDEO)

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]
