James Webb Spots Universe’s Oldest Known Galaxy: Light from 290 Million Years After the Big Bang

The James Webb Space Telescope observed what would be the oldest known galaxy, only 290 million years after the Big Bang, and the presence of oxygen has been detected. Scientists were surprised to discover that one of the galaxies, JADES-GS-z14-0, had a redshift of 14.32, making it the new farthest known galaxy. Webb has broken the record several times, but the light reaching us from this galaxy was emitted when the universe was only 290 million years old, meaning we are traveling 13.8 billion years into the past. Surprisingly bright. The light from JADES-GS-z14-0 is “surprisingly bright,” says the Webb … Continue reading James Webb Spots Universe’s Oldest Known Galaxy: Light from 290 Million Years After the Big Bang
