3 min read NASA’s Mini BurstCube Mission Detects Mega Blast The shoebox-sized BurstCube satellite has observed its first gamma-ray burst, the most powerful kind of explosion in the universe, according to a recent analysis of observations collected over the last several months. “We’re excited to collect science data,” said Sean Semper, BurstCube’s lead engineer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It’s an important milestone for the team and for the many early career engineers and scientists that have been part of the mission.” The event, called GRB 240629A, occurred…

NASA’s Fermi Finds New Feature in Brightest Gamma-Ray Burst Yet Seen

NeRD

4 min read NASA’s Fermi Finds New Feature in Brightest Gamma-Ray Burst Yet Seen In October 2022, astronomers were stunned by what was quickly dubbed the BOAT — the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASA’s Fermi Gamma-ray Space Telescope reveals a feature never seen before. The brightest gamma-ray burst yet recorded gave scientists a new high-energy feature to study. Learn what NASA’s Fermi mission saw, and what this feature may be telling us about the burst’s light-speed jets. Credit: NASA’s Goddard Space…

4 min read NASA’s Tiny BurstCube Mission Launches to Study Cosmic Blasts BurstCube, shown in this artist’s concept, will orbit Earth as it hunts for short gamma-ray bursts. NASA’s Goddard Space Flight Center Conceptual Image Lab NASA’s BurstCube, a shoebox-sized satellite designed to study the universe’s most powerful explosions, is on its way to the International Space Station. The spacecraft travels aboard SpaceX’s 30th Commercial Resupply Services mission, which lifted off at 4:55 p.m. EDT on Thursday, March 21, from Launch Complex 40 at Cape Canaveral Space Force Station in…

What’s Made in a Thunderstorm and Faster Than Lightning? Gamma Rays!

NeRD

3 min read What’s Made in a Thunderstorm and Faster Than Lightning? Gamma Rays! A flash of lightning. A roll of thunder. These are normal stormy sights and sounds. But sometimes, up above the clouds, stranger things happen. Our Fermi Gamma-ray Space Telescope has spotted bursts of gamma rays – some of the highest-energy forms of light in the universe – coming from thunderstorms. Gamma rays are usually found coming from objects with crazy extreme physics like neutron stars and black holes. So why is Fermi seeing them come from thunderstorms? About a thousand times a…

Did Astronomers See a Distant, Dying Star? Or an Earth-bound Satellite?

NeRD

What seemed a lucky break — the discovery of a gamma-ray burst in the most distant known galaxy — might instead be the flash of passing space debris. As satellites fill low-Earth orbit, such events might become common. The post Did Astronomers See a Distant, Dying Star? Or an Earth-bound Satellite? appeared first on Sky & Telescope.
