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 ...
The longest gamma-ray burst ever recorded did not behave like a quick cosmic flash. Instead, it burned across the sky for more than seven hours, forcing astronomers to rethink what powers the universe ...
The Sun’s most violent flares are turning out to be even more extreme than I, or many solar physicists, had imagined. By tracking how these eruptions light up the high‑energy sky, researchers have ...
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 ...
China’s Large High Altitude Air Shower Observatory (LHAASO), a major scientific infrastructure, has released groundbreaking results from its "Mini Survey of the Milky Way" program. With unprecedented ...
Researchers may have identified what could be a compelling clue in the ongoing hunt to prove the existence of dark matter. A mysterious diffuse glow of gamma rays near the center of the Milky Way has ...
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 ...
