By Pierre Celerier The James Webb space telescope has discovered the oldest black hole ever detected, which was thriving so soon after the Big Bang that it challenges our understanding of how these celestial behemoths form, astronomers said Wednesday. The black hole was vigorously gobbling up its host galaxy just 430 million years after the birth of the universe during a period called the cosmic dawn, according to a study in the journal Nature.

Webb measures temperature of rocky exoplanet for first time
by Juliette Collen Paris, France (AFP) The James Webb Space Telescope has measured the temperature of a rocky exoplanet for the first time, finding that a “cousin” of Earth most likely lacks an atmosphere, researchers said Monday. When the Trappist-1 system was discovered in 2017, astronomers were excited at the prospect that some of its seven rocky planets — which are roughly similar to Earth in size and mass — could be habitable. Just 40 […]
Photos of deep space as revealed by NASA’s James Webb Space Telescope
“The dawn of a new era in astronomy has begun as the world gets its first look at the full capabilities of NASA’s James Webb Space Telescope, a partnership with ESA (European Space Agency) and CSA (Canadian Space Agency),” NASA announced on July 12 as the telescope’s first full-color images and spectroscopic data were released. This was during a televised broadcast at 10:30 a.m. EDT (14:30 UTC) on Tuesday, July 12, 2022, from NASA’s Goddard […]
Webb telescope: NASA to reveal deepest image ever taken of Universe
By Issam AHMED Agence France-Presse Washington, United States (AFP) — NASA administrator Bill Nelson said Wednesday the agency will reveal the “deepest image of our Universe that has ever been taken” on July 12, thanks to the newly operational James Webb Space Telescope. “If you think about that, this is farther than humanity has ever looked before,” Nelson said during a press briefing at the Space Telescope Science Institute in Baltimore, the operations center for […]
