TRAPPIST-1: a star with three habitable planets, just 40 light years away

TRAPPIST-1: a star with three habitable planets, just 40 light years away The star is a so-called brown dwarf star, or a star that isn’t massive enough to exert the level of gravity needed to jump-start hydrogen fusion at its core.This means two things: It’s very cold (sometimes referred to as an ultra-cool dwarf star) and it doesn’t put out very much visible light.

The majority of habitable zone planets around red dwarf stars may be 'water worlds'

The majority of habitable zone planets around red dwarf stars may be 'water worlds' Finding a plausibly habitable planet in the Goldilocks zone around Proxima Centauri B, along with one around the even smaller red dwarf Trappist-1, were wake-up calls.They showed everyone we’d been paying less attention to red dwarf stars than we probably should, because red dwarf stars could play host to many more habitable-class planets than we knew.
