Australia's SpIRIT nanosatellite has snapped its first "selfie" from space, marking a successful start to its mission.

Scientists have created a perovskite-based gamma-ray detector that surpasses traditional nuclear medicine imaging technology. The device delivers sharper, faster, and safer scans at a fraction of the ...

CAPE CANAVERAL, Fla. (AP) — Scientists have discovered a gamma ray explosion outside our galaxy that’s not only exceptionally powerful, but also long-lasting. Telescopes on Earth and in space — ...

It's a celestial event that has astronomers both excited and puzzled. Dan Smith has the story of how a gamma-ray burst across ...

High energy scans or the body looking for tumors or infections could be greatly improved by adopting perovskite detectors instead of the fragile or low-resolution options currently in use, a new study ...

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 ...

In a bizarre gamma-ray space explosion whose light reached Earth in 2023, a team led by astronomer Run-Chao Chen of Nanjing ...

Gamma-ray bursts (GRBs) are the most energetic and luminous explosions in the universe. However, they are fleeting and often ...

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 ...

For over a decade, a star system on the verge of unleashing a deadly gamma ray burst appeared to have its guns trained on Earth. The so-called “Death Star,” which is also famed for looking like a ...

It's nicknamed the "Brightest Of All Time," or the "BOAT," for good reason. Astronomers have re-examined the biggest explosion ever seen, possibly the most massive explosion since the Big Bang, to ...
