Exoplanet Kepler 22b – another awesome discovery!


I don’t know if discovering Kepler 22b is an extraordinary thing cause Nasa does extraordinary things often. Anyhow, Kepler 22b was discovered 2 years ago by Nasa’s Kepler space telescope. Nasa’s Kepler mission has been finding new worlds at an incredible rate over the past year but this happens to be the 1st habitable blue planet. They have spotted around 1094 new candidate planets. In fact over 700 exoplanets have been detected & confirmed so far with thousands more still waiting confirmation.

Anyway, the scientists have confirmed that Kepler 22b is an Earth like planet & there is a possibility that it could have continents, oceans & creatures already living on it but they don’t know as yet if Kepler 22b is made mostly of gas, liquid or rock.

Kepler 22b is about twice the size of Earth & lies about 600 light years away from us towards of constellation of Lyra & Cygnus. It has temperatures that average around 72 degrees (22 Celsius). It’s slightly smaller than the sun & it orbits the star in 290 days. The extraordinary thing about this blue planet is that it also contains the right kind of atmosphere to potentially support life. It could already be inhabited. Moreover, only two confirmed exoplanets so far match the criteria for habitability in the catalogue, Gliese 581d and HD 85512b - both of which are Earthlike.

"This discovery supports the growing belief that we live in a universe crowded with life," said Dr Alan Boss, from the Carnegie Institution for Science in Washington DC.

Dr Douglas Hudgins, Kepler programme scientist at Nasa headquarters in Washington, said: "This is a major milestone on the road to finding Earth's twin."

According to Abel Méndez, Director of the PHL and principal investigator of the project: 'One important outcome of these rankings is the ability to compare exoplanets from best to worst candidates for life.'

"This is a superb opportunity for Seti observations," said Jill Tarter, the director of the Center for Seti Research at the Seti Institute. "For the first time, we can point our telescopes at stars, and know that those stars actually host planetary systems - including at least one that begins to approximate an Earth analogue in the habitable zone around its host star.”

PS I’m so sorry that this post is way too serious & all those people who presume that I create everything I write, please go through all the links below. It’s not my invention. It’s a discovery made by Nasa & I’m sure they are ones who could answer all the questions.
