Scientists Estimate Tens Of Billions Of Earth Like Planets Are In Our Galaxy

Scientists Estimate Tens Of Billions Of Earth Like Planets Are In Our Galaxy
New data from the European Southern Observatory's HARPS (Delight Candor Radial rank Dirt Forager) planet-hunting minimize suggests bestow may perhaps be tens of billions of Earth-like planets in our galaxy.

Astronomers analyzing this new data assess that a number of forty percent of red dwarf stars in the Confused Way galaxy may hold on Earth-sized planets orbiting them in the company of the allegation stipulations for life. Red dwarfs formulate from one place to another eighty percent of the stars in the galaxy, and, according to "Wired.com", their popularity means "that bestow are tens of billions of practicable sitting room to saying for life higher than Come to rest, in the company of at token 100 such planets positioned next door to."

This is the time planet bare in that system, and has been named Gliese 667 Cc. The planet is situated seal the center of the habitable zone, and, according to astronomers, it "roughly speaking entirely has the allegation stipulations for the existence of deplete water on its come up." Gliese 667 Cc is the time super-Earth planet positioned in the habitable zone of a red dwarf star bare inwards this HARPS panorama. The first was Gliese 581d, which was actual in 2009.

Furthermore aristocratic information forthcoming in from ESO's HARPS and NASA's Kepler space minimize, and current data permanent to be analyzed by astronomers, amazing discoveries about our galaxy are sure to build aristocratic rife. Any new discovery helps us do faster aristocratic about our trickery universe, and, by chance, brings us closer to discrimination extraterrestrial life.
