Has JWST Finally Found the First Stars in the Universe?
New observations from JWST hint at pockets of new gas in the halo of more evolved galaxies, where these first-generation…
Here's How You Could Get Impossibly Large Galaxies in the Early Universe
A study by an Israeli team of astronomers offers a solution to the "impossibly massive" galaxies Webb observed.
Can JWST see Galaxies Made of Primordial Stars?
With a bit of luck, the Webb Space Telescope might be able to see a galaxy full of the first…
Did Supermassive Black Holes Collapse Directly out of Giant Clouds of gas? It Could Depend on Magnetic Fields
New research shows how the seeds of Supermassive Black Holes (SMBHs) could have formed from gas clouds with amplified magnetic…
What Telescope Will Be Needed to See the First Stars in the Universe? The Ultimately Large Telescope
The oldest stars in the Universe are cloaked in darkness. Their redshift is so high, we can only wonder about…
