The universe's early galaxies are way brighter than they should be. The James Webb Space Telescope's discovery of brightly glowing gas around 90% of primordial galaxies may explain why.

      • A big telescope called James Webb that can see very far in space and time. It can see how the first stars and galaxies were born after the Big Bang, which was a huge explosion that created everything.
      • James Webb found out that most of the first galaxies had a lot of gas around them that was very bright. The gas was lit up by the light from the stars inside the galaxies. The gas also helped make more stars by cooling down and clumping together.
      • This discovery is important because it helps us understand how the first galaxies grew and how they made the different elements that we have today. The article also says that this discovery is surprising because the first galaxies were much brighter and bigger than we expected.
