EVEN IF we could travel the speed of light, by the time we got a probe there and got images back most of us would be dead.

Yeah, that is the sad reality.

"Just 39 light years away"...there is 63,000au in a light year.an au =93 million miles..Just saying.

It's a fantastic discovery indeed, very happy to hear about it.

The first planets could be tidally locked to their star, too close to maintain life as well. At least 3 appear to be in the "Habitable Zone" in which water could exist in liquid form, but all three of them could actually be like Venus. Sure Venus is very similar to Earth in shape and all, but it'll kill you as soon as you try to stand on it's surface. The atmosphere there is wild.

That could be the case with these planets in the habitable zone, the last one is a bit too far from it's star to maintain liquid water on it's surface, but it might keep it liquid under it's surface (something like Europa does).

Nonetheless, amazing discovery. Makes you wonder how many TRAPPIST-1-like systems are out there... in the whole f* universe.






Do we have a proper Astronomy/Space News thread?. Mind blowing stuff happen almost weekly!

Actually they probably dont have any atmosphere at all. Red dwarfs of that size emit HUGE amounts of X ray radiation the first million years of their lives. So if there was an atmosphere in those planets, it would have been blasted away long time ago :P

Indeed, Red Dwarfs are actually quite unstable and dangerous despite being low-mass and having a life span that extends to like Trillions of years...

They're good candidates however, if we find life in one of these systems they would be extremely advanced and complex, not talking about a whole civilization, but rather some sort of life, simple yet incredibly complex to survive in said context.

Complex in what way, because the best earth candidate would be the water bear or similar creature.

Complex in the sense of how developed a living thing has to be in order to survive in such enviroment.

But I'm probably wrong, sure, I'm no Astrobiologist.
