Now that TRAPPIST-1 is the trendiest star system in the galaxy, astronomers and nerds alike are clamoring to learn more about it. We know that the seven-planet system contains three planets in the habitable zone, which means they could hypothetically support liquid water, and even life. We also know that the TRAPPIST-1 planets orbit around their ultracool dwarf star very closely, which could be good or bad for finding life, depending on who you ask. And now, we know a little more about the most distant planet in the bunch.
Less than a week ago, the citizens of Earth were introduced (technically, re-introduced) to a star system 39 light years away hosting seven Earth-sized exoplanets, three of which lie squarely in the habitable zone. As if that wasn’t exciting enough, researchers are now suggesting that a fourth of the TRAPPIST-1 planets might be habitable, too—if we stretch our imaginations a bit.
Astronomers have found at least seven Earth-sized planets orbiting the same star 40 light-years away, according to a study published Wednesday in the journal Nature. The findings were also announced at a news conference at NASA Headquarters in Washington.
