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 ...

Light curve of the gamma-ray flare (bottom) and collection of quasi-simulated images of the M87 jet (top) at various scales obtained in radio and X-ray during the 2018 campaign. The instrument, the ...

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 ...

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 ...

A team of astronomers including George Washington University physics Ph.D. student Eliza Neights recorded an extraordinary cosmic outburst this July which likely heralds a new kind of stellar ...

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 ...

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...
