Yesterday the number of "worlds aliens”That have been discovered by man. There is talk of a thousand new exoplanets.
The satellite "KeplerIn fact, after various problems due to a gyroscope failure, it broke a record. A great achievement for science and astronomy: many exoplanets have been discovered.
But let's start from the beginning. Kepler is a satellite-telescope launched on 7 March 2009 from Cape Canaveral, with the aim of discovering new extrasolar planets. And yesterday, in one fell swoop, Kepler discovered 1.284 new planets: "The largest discovery of planets all together," it was said. Furthermore, nearly 550 of these planets are expected to be rocky, like the Earth, and therefore could host life.
Nine of these planets would be habitable, because they orbit neither too far nor too close to their "sun", with surface temperatures therefore that could allow the presence of liquid water and even extraterrestrial life forms. "Today's discovery - announced Ellen Stofan, coordinator of the NASA project - gives us the hope that somewhere, out there, there is a planet orbiting a star similar to the sun, and that it could be a new Earth».
