Inhabitable planets?
« on: February 23, 2017, 07:51:55 pm »
Did anyone see this about the 3 possibly inhabitable planets in the dwarf star Trappist-1 solar system?

I saw something about the possibility of life on 7 planets they believe to be similar to earth.  About 40 light years away.  I think it said that 3 of them were thought to have temps a little warmer to a little cooler than earth.

1.    The ones that learn by reading.
2.    The few who learn by observation.
3.    The rest of them have to pee on the electric fence and find out for themselves.    Will Rogers

In general, yes.  Not that source, though.  They're going to test some for water, oxygen, methane, etc soon.  Hubble, I think, then another project in 2020 or so.

The other project is the James Webb Space Telescope, due to launch in 2020. It's so big that the primary mirror has to be folded up for launch. And they better get this one right, because it's going to be sent so far away that it can't be fixed by a shuttle, even if they were still flying.

Yeah, what was up with flubbing the mirror on Hubble?

I'm curious what affect a smaller, cooler sun would have on humans living on such a planet.  For that matter, is that star older or younger than ours?

Of course, the real kicker is, is there already life on those planets.

Would we have a ”Prime Directive”?  No flaming, now.

Worse, yet, if there is life--even microbial--landing on the planet could have a devastating effect.  White man's diseases killed more American Indians that our wars with them ever did.  How would we avoid this?
