Ooh, look I read another paper. Hurrah !

This one is about an incredibly, superlatively faint galaxy discovered back in 2018 that I'd forgotten about completely. Here the authors use Hubble observations to rule out an old stellar population - it only has young stars. This most likely means it's a tidal dwarf, having just recently formed due to tidal interactions but not likely to last long.

#JWST reaches new milestone in quest for distant #galaxies.

The light from these galaxies has taken more than 13.4 billion years to reach us implying they existed 400 million years after the big bang, when the #universe was only 2% of its current age.

These galaxies are extremely faint because of their great distance from us. Astronomers can now explore their properties, thanks to JWST's exquisite sensitivity.
