23 February 2017 - sad giant star

Or we could have been born in a place like the 7-planet system around
red dwarf TRAPPIST-1, just announced, where all seven planets (which
are full-sized and have no connection with Snow White) are closer
together than any two planets around our comparatively giant sun. You
would be able to see surface features of other worlds with the naked
eye. On the downside, the red dwarf will shine for trillions of years,
so the word “sustainable” would be hard to get out from under.
