The Universe's First Stars Were Shaped By Turbulence and Were Not As Massive as Thought
For a long time, astrophysicists thought that the Universe's first stars, called Population III stars, were uniformly massive. It seemed like the conditions they formed in were calm and serene, which favoured massive stars. But new research based on high-resolution simulations show that conditions were more chaotic than thought, and gas cloud turbulence means that Population III stars were not all massive. This affected the metallicity of the next stars to form.
Another Early Universe Surprise from the JWST: A Mature Galaxy Cluster
The JWST found a galaxy cluster from 10 billion years ago that's far more developed than it should be, according to cosmological models. The cluster is also the most distant strong gravitational lens that we know of. Detailed observations across the spectrum show that the cluster is still undergoing mergers.
"Little red dot" in early Universe is a naked supermassive black hole
The black hole accounts for over two-thirds the mass of the object it inhabits.
