NASA’s Kepler Space Observatory has found two new planetary systems with a total of seven planets. Three have similarities with Earth.
– researchers can not say whether there is life on the newly discovered planets, but the discovery shows that we are coming closer to finding Earth-like planets entirely, says astrophysicist Knut Jørgen Roed Odegaard NTB.
planets Kepler-62e, 62f-and-69c are so-called super-Earths. Ødegaard explains that they are somewhat larger than our planet, but far less than large gas planets.
astrophysicist explains that it means that the surface temperature of planets allows water to be in liquid form.
– This is one of the most interesting planets that have been found outside our solar system, he said.

Earth-like planets that NASA Observatory have found, is in Alpha Centauri system.
Kepler-62 is 1,200 light years from Earth in the constellation Lyra.
Stein Planet
Kepler-62 system it is found five planets and Kepler-69 system is the discovery of two. Two of them orbiting a star that is smaller and cooler than our Sun.
– The most interesting is perhaps 62f which is only 40 percent larger than Earth. It is likely a rocky planet.
62e are located in the inner part of the habitable zone and is about 60 percent larger than our own planet.

The third planet, 69c, is 70 percent larger than Earth and orbit in the habitable zone of a sun-like star.
– The composition of this planet is still unknown but with a period of 242 days, the memories of Venus in our solar system, says Ødegaard.
Milestone
The other planets that have been discovered in the two planetary systems have orbits close to its star and is too hot for life to exist there.
Kepler space telescope has since 2009 monitored 150,000 stars looking for tiny eclipses that occur when Earth-like planets passing in front of its host star.
– We only know a star that is host to a planet where there is life, and the star is the sun. Finding a planet in a habitable zone around a star like our Sun is a milestone in the quest to find planets like Earth, says Kepler scientist Thomas Barclay Bay Area Environmental Research Institute, Sonoma, California.
