British cosmologist and astrophysicist Martin Rees believes that machines powered by Artificial Intelligence (AI) will inherit the Earth – and the stars. He is also persuaded that advanced aliens could be inconceivably different from life as we know it, as different from us as we are from a bacterium.
Yesterday NASA announced the discovery of an “Earth 2.0” far away in the sky. The planet, named Kepler 452b, is about 60 percent larger than Earth and is about 1,400 light-years away. The planet orbits a star similar to the Sun, slightly brighter and larger. Kepler 452b is the first Earth-sized world that has been found in the habitable zone of a sun-like star.
Most stars have planetary systems. In astronomy, this is new information. Many stars are not bright enough to support life, at least according to current science, but we do now know that small, rocky planets like Earth are the rule, not the exception throughout the solar system, raising the possibility of human space colonization by several fold.
NASA announced today some new discoveries about planets in the solar system, and specifically in the constellation Cygnus. They now know more about an exoplanet they’re calling Kepler-452b, which is about 1400 light-years away from Earth, and orbits its sun only slightly slower than our planet. It has twice our gravity and five [...]
