- James Webb: Earliest and most distant galaxy ever observed
Jun 12, 2023 · New data from NASA’s James Webb Space Telescope has pinpointed the reason. By analyzing new observations from NASA’s James Webb Space Telescope, a team led by Simon Lilly of ETH Zürich in Switzerland found evidence that galaxies that existed 900 million years after the big bang ionized the gas around them, causing it to become transparent.
Webb measures the galaxy to be more than 1,600 light years across. Many of the most luminous galaxies generate the majority of their light via gas falling into a supermassive black hole.
Mar 4, 2024 · The formation of the first stars and galaxies marks a fundamental shift in cosmic history, during which the universe evolved from a dark and relatively simple state into the highly structured and complex environment we see today. In future Webb observations, Maiolino, Übler, and their team will explore GN-z11 in greater depth, and they hope to ...
Jul 27, 2022 · Webb’s images reveal a wealth of galaxies glimmering in the distant cosmos, appearing as they did just a few hundred million years after the Big Bang, 13.8 billion years ago.
Jun 12, 2024 · Looking at a time near the end of the Era of Reionization, Webb results clearly show tiny galaxies clearing space around themselves, out to about 2 million light-years in radius. This connects to the intense star formation observed in early galaxies. Young, massive, hot stars pumped out huge amounts of ultraviolet light, which ionized the gas ...
Mar 4, 2024 · Looking deeply into space and time, two teams using NASA’s James Webb Space Telescope have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old. Initially detected with NASA’s Hubble Space Telescope, this galaxy — one of the youngest and most distant ever observed — […]
