NASA has confirmed the existence of 219 extrasolar planets. Ten of those planets are close to Earth in size, and they are located in the Habitable Zone , which is considered to be a suitable environment for life to be born.

NASA announced the discovery of a new planet on June 20, 2017 in local time, and on Twitter, scientists are excited to discover the possibility of 219 new worlds using @ NAS AKepler ! I am making a report on my mind.



Kepler started exploring in 2009, and has reported the possibility that many extrasolar planets exist so far 3000 light years away from the earth. With this discovery, there are 4034 extrasolar planet candidates, of which 2335 have been identified as extrasolar planets, and 21 are in the size of the Habitable Zone with a size close to the Earth. . These stars are thought to provide clues as to how the earth was born and developed.

Kepler searches for planets using a ' transit method ' that detects changes in brightness as the planets cross stars. And if there is a possibility of a planet, it measures weight, size, orbital period, distance from a star, etc. At this time, the identification of the planet has been done by human hands until now, according to the scientist Susan Thompson, 'This is different, this is not, this is the possibility of a star ... Planet The method of identifying one by one was very time-consuming.

So the research team simulated 'right' and 'wrong' signals and compared them to actual data from Kepler's mission to uncover planet types that are easy to overestimate and underestimate. By using this method, it is possible to evaluate stars more accurately than before.



In addition, by collaborating with the engineers of WM Keck Observatory in Hawaii for 5 years, it becomes possible to guess 'Classification of extrasolar planets in the family tree' that researcher Benjamin Fulton talks about Yes. The classification of the planets includes, for example, the planet 'super-Earths' made of rocks 1.5 times the size of the earth and the gas planet 'mini-Neptunes' 2.5 times the size of the earth. Has been used for a long time, but with this classification, the border is clearer. This is a very important development in the discovery of the planet.



Kepler carried out the first observation mission in the mission from 2009 to 2013, and in 2014 started the “K2 mission” that incorporates solar pressure into attitude control. The K2 mission will be held until the fuel runs out around 2018.
