7 Earth-sized Worlds Found in Nearby Star System
OK, here's the bad news: we have not found aliens.
But we have found the most incredible star system to date.
Here are 5 amazing facts about it:
The TRAPPIST-1 system has 7 Earth-sized planets.
Seen from Earth, all 7 planets pass exactly in front of the red dwarf star as they orbit.
At least the inner 6 are probably rocky like Earth.
3 of the planets could harbour oceans of water.
ESO's future European Extremely Large Telescope will be able to detect water.
Imagine if one day, life is found on one of these worlds...
