The Potential for Habitable Worlds Just Improved

Trappist 1, a red dwarf star barely larger than Jupiter, apparently has three planets circling in close. That's good in this case. Small, dim, cool, Trappist 1 has a habitable zone snugged right up close to the star. There is a possibility for a habitable zone on one world at least, scientists suspect.

If this all proves out, then potential earths might be even more common, with many circling stars doing a very slow burn. Red dwarf stars burn low and slow, lasting far longer than our sun. Imagine a world with life around such a star. There'd be all sorts of time for intelligent life to develop there, perhaps several times as the eons drift by.

Keep your eyes on the skies. And for those dour party poopers who declare it is unlikely that two intelligent races will occupy anything like stars nearby during their lifetimes as time is long, space is vast, and extinction can come on suddenly ... well, guys, you've got a lot of work to do to prove that negative position. I'll take a more hopeful stance and wait for further news.
