Astronomers have Discover Another Earth Video

NASA’s Kepler Space Telescope exposed an Earth-like planet circling a nearby star inside the Goldilocks zone of our galaxy. Kepler-186f is around 500 light-years from Earth in the Cygnus group.

The habitable zone, also recognized as the Goldilocks zone, is the area approximately a star within which planetary-mass substance with enough atmospheric pressure can sustain liquid water at their surface. While it has been predictable that there are at slightest 40 billion Earth-sized planets circling in our Milky Way Galaxy, this specific finding is labelled the first Earth-sized planet to be exposed in the habitable zone of one more star.In adding to Kepler-186f, there are 4 other planets that circle a nearby star within the Kepler-186f system. What this means is that if the neighbouring star to this planet is presently like our Sun, then the likelihood of life on this planet exponentially increase.

“We know of just one planet where life survives – Earth. When we hunt for life exterior our solar system, we emphasis on discover planets with features that mimic that of Earth,” said Elisa Quintana, research scientist at the SETI Institute at NASA’s Ames study Center in Moffett Field, Calif., and lead author of the paper issued on 27th January in the journal Science. “Discovering a habitable zone planet similar to Earth in size is a main breakthrough.”

The neighbouring star to Kepler-186f has half the mass and size as our solar system’s Sun & only gets one-third of the power that we get from our Sun. Kepler-186f circles its star once each 130 days.
