Astronomers have long debated what kind of chemistry might serve as a bona fide alien biosignature. With the launch of the James Webb Space Telescope, those ideas may be put to the test.

"Last year when we first published our work on very high redshift z>11 in SMACS 0723 we were very badly smashed."

Yan et al. used a stricter selection filter, but z_photometric > 13 galaxies still don't show the expected rapid evolution.

OK, it's really cool that the James Webb Space Telescope found methane and carbon dioxide in an exoplanet's atmosphere, but it also might have found dimethyl sulphide. On Earth, this molecule is only produced by life and is considered a key biosignature for planets like the one studied.

Scientists using have found an abundance of methane and carbon dioxide in the exoplanet K2-18 bโ€™s atmosphere. With a shortage of ammonia, these results are consistent with the presence of an ocean underneath a hydrogen-rich atmosphere: webbtelescope.pub/3r1yWHa

JWST Accidentally Found 21 Brown Dwarfs

JWST is the most powerful telescope ever built by humanity, and it's scanning into the very limits of the observable Universe to see the first galaxies coming together. However, as part of several galactic surveys, astronomers have already identified 21 brown dwarf candidates in the data, much closer to home. Some are as close as around 325 light-years, others as far as 13,700 light-years - farther than any brown dwarfs discovered. Quite a handy side-benefit.

Not my area of science but looking at ACT-CL J0102-4915 pretty much convinces me that there were only about 12 galaxies in the early universe and the whole sky is just gravitationally lensed versions of them.
That is all
