7 Earth-Size Worlds Found Orbiting Star; Could Hold Life
"The planets circle tightly around a dim dwarf star called Trappist-1, barely the size of Jupiter. Three are in the so-called habitable zone, where liquid water and, possibly life, might exist. The others are right on the doorstep. Picture this: If Trappist-1 were our sun, all seven planets would be inside Mercury's orbit. Mercury is the innermost planet of our own solar system."
They are "only" forty light-years away, which may someday be reachable for us. (It's not with today's technology.)
Since this is an old star - it has likely already gone nova - IF there was life and IF it survived the nova stage, perhaps the question we should be asking ourselves is, "do they have the capability of reaching US?", rather than saying, "oh don't worry, we don't have the technology to reach out that far...."
