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.
