In 2019, the world was mesmerized by the first-ever image of a black hole, courtesy of the Event Horizon Telescope (EHT). The striking image depicted the supermassive black hole at the center of the ...

In the final moments before two neutron stars collide, their magnetic fields spiral into chaos, twisting and snapping as they ...

New simulations performed on a NASA supercomputer are providing scientists with the most comprehensive look yet into the ...

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly ...

Dense knots of dust in otherwise normal galaxies dim the light of a dark gamma-ray burst (center). The dust absorbs most or all of a burst’s visible light but not higher-energy X-rays and gamma rays.

An international science team says NASA’s Fermi Gamma-ray Space Telescope has observed high-energy light from solar eruptions located on the far side of the sun, which should block direct light from ...

NASA supercomputer simulations reveal X-ray and gamma-ray signals emitted in the final milliseconds before neutron star mergers, providing insights for future observatories and gravitational-wave ...

Astronomers analyzing 13 years of data from NASA's Fermi Gamma-ray Space Telescope have found an unexpected and as yet unexplained feature outside of our galaxy. Astronomers analyzing 13 years of data ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...
