Mysterious radio burst came from group of galaxies in distant universe. The Hubble Space Telescope has pinpointed the origin of the most distant known fast radio burst, which hit our planet in 2022.

The galaxies in the group seem to be interacting and could even be in the process of merging, which might have triggered the fast radio burst, according to the researchers.

Stephan's Quintet is an interesting group of galaxies. It looks like five galaxies clustered together in the sky, so when they were discovered in the 19th century, that's how they were cataloged.

Astronomers have discovered an extremely rare group of five 'dwarf' galaxies about 117 million light years away. It is highly uncommon for them to appear in groups.

These galaxies – some hundreds of them and called the Little Red Dots – are very red and compact, and visible only during about 1 billion years of cosmic history.
