A team of astronomers used the James Webb Space Telescope to study the exoplanet TRAPPIST-1 c, which is one of seven rocky planets orbiting an ultracool red dwarf star 40 light-years from Earth. The team found that the planet's atmosphere, if it exists at all, is extremely thin.
TRAPPIST-1 c is about the same size as Venus and receives a similar amount of radiation from its host star as Venus gets from the Sun. This led scientists to believe that the planet might have a thick carbon dioxide atmosphere like Venus. However, the Webb observations suggest that this is not the case.

A shame. It sounded like a nice place to build a monastery.

1C might be a bust, but the others that are further out could be a bit more promising.

ehh, it's 232 trillion miles away anyway better we find out now than millions of years later traveling there haha. Why aren't they pointing JWST at G type and K type stars and the plethora of exoplanets orbiting them in the milkyway? They say 7% of the stars in the galaxy are G type and there's roughly 400 billion stars in the milkyway that equates to 28 billion G type stars and exoplanets at having just one planet around a G type star and then K type stars and it's said 13% of the stars in the milkyway are K type stars and the equates to 52 billion K type stars which in turn equates to 52 billion possible exoplanets and it's said that there's on average 1.6 exoplanets per star. But yet all we ever hear about is Red Dwarfs, M type stars. We don't live around a red dwarf but yet that's all we ever hear about. And why hasn't JWST been pointed at Alpha Centauri A & B maybe it can resolve a planet around either of those stars and i know that's difficult thing to do but they say there's a 75% chance either has a earth like planet orbiting one or both of them. Great video Tony , sir you are the BEST! I look forward to monday through friday for explanet radio.

JWST gets orders placed to look at certain things which doesn't take too long. Then comes the shifting through data, double-checks, triple checks, presenting it, peer-reviewing, all that jazz which takes time. What you want could already be in the que to check many viable worlds but I'm not privy to a list of orders for the satellite. It's much simpler to go after those worlds you already know many things about to see if your measurements have really been correct so that more hypotheses can be made about the make up of planets and what one should look for.
