Skip 39 light-years across our galaxy, and you’ll arrive at
Trappist-1, an ultracool dwarf star with a band of special
followers. This dim star hosts seven Earth-like planets within its
habitable zone, according to a study published today in the
journal Nature. Exoplanets are a dime a dozen these days, but due
to unique properties in this exosolar system, the new discovery
may usher in a movement in the hunt for habitable worlds — one
where astrophysicists can ascertain the presence of life without
traveling across the cosmos.
“Ultracool” means that it’s a low-radition dwarf star, but the adjective works the other way too. They even registered a clever domain name.
