A groundbreaking new survey from China’s LHAASO observatory has unveiled powerful ultrahigh-energy gamma-ray emissions across ...

Watch an animation of a black hole shooting jets of particles through a "collapsing star at nearly the speed of light" and ...

Today in the history of astronomy, satellites Vela 3 and 4 make the first detection of gamma-ray bursts.

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 ...

This is the first time an object in its class has been detected in X-rays. The discovery could lead to a better understanding ...

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

The versatile cannabis plant could, some scientists think, one day be useful for lunar and Martian colonists. For now, researchers will subject its seeds to radiation in orbit and see what happens.

From the ISS, scientists are capturing rare lightning above storms that could impact radio, climate, and safety.

This is the first time an object in its class has been detected in X-rays. The discovery could lead to a better understanding ...

Short, intense blasts called terrestrial gamma-ray flashes are so luminous they can be seen from space, and last for mere fractions of a millisecond (SN: 1/10/23).

“FGFs are typically much weaker than the well-known Terrestrial Gamma-ray Flashes (TGF) observed from space since the 90s,” said Martino Marisaldi, a physicist at the University of Bergen in ...
