Today, the European Space Agency's gamma-ray telescope ends its observations. During its 22 years in space, Integral has reshaped our view of the most dramatic events in the universe. The high-energy ...

Astronomers have determined what caused the brightest cosmic explosion ever recorded. Lasting a matter of minutes, the gamma-ray burst, named GRB 221009A, was observed by astronomers in October 2022.

The longest gamma-ray burst ever recorded did not roar for seconds or even minutes, but for a staggering seven hours, forcing astronomers to rethink how some of the most violent explosions in the ...

NASA sent a retired Cold War spy plane on a storm-chasing mission, and it discovered that big thunderstorms are very radioactive. Large thunderstorms produce so much gamma radiation that the clouds ...

Solar physicists fromNJIT’s Center for Solar-Terrestrial Research (NJIT-CSTR) have uncovered the elusive source of intense gamma rays unleashed during solar flares. These high-energy radiation signals ...

Down here at the bottom of our ocean of air, it’s easy to get complacent about the hazards our universe presents. We feel safe from the dangers of the vacuum of space, where radiation sizzles and ...

A new study, published in The Astrophysical Journal, has produced a compressed 14-year movie of the sun observed in gamma rays, a visualization tool which revealed that—contrary to the expected ...
