Yesterday the number of “worlds aliens" who have been discovered by man. There is talk of as many as a thousand new exoplanets.
The satellite "Kepler” of NASA, in fact, after various problems due to a failure of a gyroscope, broke a record. A great achievement for science and astronomy: they have been discovered many extrasolar planets.
But let's start from the beginning. Kepler is a satellite telescope launched on March 7, 2009 by Cape Canaveral, with the aim of discovering new exoplanets. And yesterday, in one fell swoop, Kepler discovered 1.284 new planets: "The largest discovery of planets all together", it was stated. Additionally, nearly 550 of these planets should be rocky, like Earth, and therefore could host life.
Nine of these planets would be habitable, because they orbit nor too much far nor too close to their "sun", with surface temperatures that could therefore allow the presence of liquid water and even extraterrestrial life forms. «Today's discovery – announced Ellen Stofan, project coordinator from NASA – gives us hope that somewhere out there, there is a planet orbiting around to a star similar to the sun, and which could be one new Earth».
