By Francis Reddy, NASA's Goddard Space Flight Center March 29, 2023 Gamma-ray bursts are the most luminous explosions in the cosmos.
On Sunday, October 9, 2022, a pulse of intense radiation swept through the solar system so exceptional that astronomers quickly dubbed it the BOAT – the brightest of all time. The source was a gamma-ray burst (GRB), the most powerful class of explosions in the universe.

Giant Cosmic Explosion May Be Biggest Since Human Civilization Began, Say Scientists
The Hubble Space Telescope's Wide Field Camera 3 revealed the infrared afterglow (circled) of the ... [+] BOAT GRB and its host galaxy, seen nearly edge-on as a sliver of light extending to the burst's upper right. This animation flips between images taken on Nov. 8 and Dec.
"GRB 221009A was likely the brightest burst at X-ray and gamma-ray energies to occur since human civilization began," said Eric Burns, LSU Department of Physics and Astronomy assistant professor.
Earth-Sized Planet In 'Solar System 2.0' Has No Atmosphere, Says Webb Telescope
Scientists using the James Webb Space Telescope have done something incredible by measuring the temperature of rocky exoplanet TRAPPIST-1b.
Astronomers are desperate to explore smaller, rockier and more Earth-like planets such as those in the TRAPPIST-1 system, where seven rocky planets orbit a red dwarf (M) star about 40 light years distant in the constellation Aquarius.
Nasa's Webb telescope finds no atmosphere in Earth-sized planet in solar system thought to have ...
The study also marks the first detection of any form of light emitted by an exoplanet as small, and as cool as, the rocky planets in our own solar system.
"These observations really take advantage of Webb's mid-infrared capability. No previous telescopes have had the sensitivity to measure such dim mid-infrared light," study co-author Thomas Greene said.
