Strong damped Lyman-alpha absorption in young star-forming galaxies at redshifts 9 to 11. (https://pubmed.ncbi.nlm.nih.gov/38781391/)

These scientists used a powerful telescope called the James Webb Space Telescope to look at very far away galaxies. They wanted to understand how much hydrogen gas, which is important for making stars, was present in these galaxies when the universe was very young. They studied 12 galaxies that were really far away, and they found three galaxies that had a lot of hydrogen gas around them. These galaxies were formed around 400 to 600 million years after the Big Bang, which is a really long time ago. This discovery showed that these galaxies had a lot more hydrogen gas than expected, and it helped the scientists learn more about how stars form in the early universe.
