Black Holes or Black Hole Stars? Astronomers Spar Over Webb Telescope’s ‘Little Red Dots.’

SMRTR summary

Astronomers using the James Webb Space Telescope are debating the nature of mysterious objects called "little red dots," spotted in some of the telescope's earliest images. These faint smears of light date back to the first billion years after the Big Bang, when galaxies were just forming from hydrogen and helium gas. Scientists are split on whether these objects are black holes, a new type of "black hole star," or something else entirely.
