NASA Finds Solar System With Seven Earth-Sized Planets
The truth really is out there. NASA revealed yesterday that it’s discovered seven rocky, Earth-sized planets orbiting dwarf star Trappist-1, just 39 light years away. Three are in the habitable zone and could contain liquid water. The fact that Trappist-1 is a dwarf star should also accelerate the search for life-sustaining exoplanets, because scientists have previously focused their search on stars roughly the size of our sun. Dimmer dwarf stars, less distracting to sensitive research instruments, will make it easier to study the planets themselves.
