Fermi spots a supernova's 'fizzled' gamma-ray burst

On Aug. 26, 2020, NASA's Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that had been racing toward Earth for nearly half the present age of the universe. Lasting only about a second, it turned ...

Space scientists solve a decades-long gamma-ray burst puzzle

An international team of scientists, led by astrophysicists from the University of Bath in the UK, has measured the magnetic field in a far-off Gamma-Ray Burst, confirming for the first time a decades-long theoretical prediction—that ...

Front-row view reveals exceptional cosmic explosion

Scientists have gained the best view yet of the brightest explosions in the universe: A specialized observatory in Namibia has recorded the most energetic radiation and longest gamma-ray afterglow of a so-called gamma-ray ...

GECAM team reports first detection of gamma-ray transients

In the early morning of Jan. 20 (Beijing Time), the Gravitational Wave High-Energy Electromagnetic Counterpart All-sky Monitor (GECAM or Huairou-1) team reported their first detection of a gamma-ray transient (GRB 210119A) ...

Astronomers unmask cosmic eruptions in nearby galaxies

A brief burst of high-energy light swept through the solar system on April 15, triggering many space-based instruments, including those aboard NASA and European missions. Now, multiple international science teams conclude ...
