The first ever space telescope, the Orbiting Astronomical Observatory 2 (OAO-2), was launched into the low Earth orbit in ...

which is a key property of gamma-ray bursts that can help reveal how these violent events produce such a phenomenal amount of energy - more than the Sun’s entire output over its 5 billion year ...

In October 2022, a blast of light from deep space outshone anything humanity has ever witnessed. The gamma-ray burst, later named “The BOAT,” unleashed more energy in seconds than our sun will emit in ...

A microquasar belonging to our Milky Way galaxy has set records by generating cosmic rays with energy levels never before ...

A groundbreaking simulation reveals how neutron star mergers forge black holes, generate gamma-ray bursts, and scatter gold ...

For years, astronomers puzzled over the mystery of where the heaviest elements in the universe—like gold, uranium, and platinum—come from. Scientists understood that these elements had to form under ...

Study reveals that high-energy cosmic rays are born in magnetic fields during neutron star mergers, a prelude to black holes.

Strikes on any nuclear facilities could, in theory, release clouds of deadly radiation that endanger human lives and health. But in the case of Israel’s attacks on Iran overnight Friday, that appears ...

Thunderstorms are known to generate gamma rays, the highest energy radiation on Earth. But pinning the burst to a specific bolt is new.

Like high-energy strobe lights, these outbursts consisted of short pulses of gamma rays that repeated over tens to hundreds of milliseconds, the team reported in a second paper in Nature.

Invisible to our eyes, gamma rays burst from supernova explosions as well as the hottest and most energy dense objects in the cosmos, like pulsars, those highly magnetized neutron stars that emit ...
