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.
Remember Those Impossibly Massive Galaxies? They May Be Even More Massive
A new analysis of those James Webb images showed that the galaxies it observed (deemed "too massive") could be even…
The First Stars May Have Weighed More Than 100,000 Suns
The universe was simply different when it was younger. Recently astronomers have discovered that complex physics in the young cosmos…
