1 day ago · Astronomers using the James Webb Space Telescope have found that some of the universe's oldest galaxies are much brighter and heavier than scientists thought. The finding could lend credibility to ...
Jun 15, 2023 · Webb’s data shows that these relatively tiny galaxies drove reionization, clearing massive regions of space around them. Over the next hundred million years, these transparent “bubbles” continued to grow larger and larger, eventually merging and causing the entire universe to become transparent. Lilly’s team intentionally targeted a ...

Aug 26, 2024 · But now astronomers can explain some surprising recent discoveries. Not long after the James Webb Space Telescope began science operations in July 2022, breathless headlines proclaimed that observations of distant galaxies were “breaking theories of cosmic evolution.”. Astronomers had found galaxies that appeared much brighter than expected.
3 days ago · A group of astronomers analyzing data from the James Webb Space Telescope say some of the oldest galaxies in our universe appear much larger and brighter than expected, suggesting they formed ...

Aug 26, 2024 · This extra light can make it appear that the galaxies contain many more stars, and hence are more massive, than we would otherwise estimate. When scientists remove these galaxies, dubbed “little red dots” (based on their red color and small size), from the analysis, the remaining early galaxies are not too massive to fit within predictions of the standard model.
