The nature of `little blue dots': #LittleRedDots

As foretold by the prophecy of #Soundgarden
#Astronomy #LittleRedDots

Astronomers discover a new kind of cosmic object – a black hole ‘star’
The body is the size of the entire solar system and glows with a brilliant red light about 30bn light years from Earth

No evolution in the number density of #LittleRedDots from cosmic dawn to cosmic noon: https://arxiv.org/abs/2606.30253 -> Backyard Black Holes: https://astrobites.org/2026/07/09/backyard-lrds/
