Scientists are puzzled by the discovery of tiny, bright objects in the early universe by NASA's James Webb Space Telescope. These objects, dubbed "little red dots," challenge existing theories about galaxy and supermassive black hole formation. Researchers found evidence of ancient stars and supermassive black holes in these objects, contradicting current models. The objects, identified about 600-800 million years after the Big Bang, are much older and more massive than expected. The team, led by Penn State researchers, aims to unravel the mysteries surrounding these unique findings through further observations. The objects, only a few hundred light years across, contain a dense population of stars and unexpectedly large supermassive black holes. The discovery raises questions about the early universe's evolution and challenges current understanding of cosmic history. Further research and observations are needed to shed light on these perplexing objects and their implications for our understanding of the universe.

Astronomers see a black hole awaken in real time
A massive black hole in galaxy SDSS1335+0728 has unexpectedly awakened, transforming it into an active galactic nucleus. This long-lasting event challenges previous astronomical knowledge on galaxy dynamics.
A black hole of inexplicable mass
The James Webb Space Telescope observed galaxy J1120+0641, revealing a mature quasar with a billion solar mass black hole at cosmic dawn. This challenges theories on black hole growth, suggesting they may start with substantial masses. The study sheds light on early black hole development, showing unexpected normalcy in early quasars, challenging assumptions on their evolution.

14 commentsIf these old galaxies are so dense, could that help explain why their black hole is disproportionately large? With so many stars so close together, maybe they’re gravitationally interacting with each other far more, causing a lot more instability. So you have a bunch of stars knocking each other around and as a byproduct more of them get flung close enough to the center to get captured by the black hole?
What is it telling us? Our current ideas are certainly wrong. Looking forward to what it leads us to.
If the diameter of a galaxy is one-thousandth, then its volume is one-billionth. They can't both be one-thousandth.
Pretty crazy galaxies.
My god, it's full of stars
