Cosmic rays seen at Earth show a wide range of particle energies, from 107 electron-volts (eV) to more than 1020 eV, the latter being about the same as the kinetic energy of a 450 gram football ...

Glowbug-2 instrument successfully launched on board the Department of War (DoW) Space Test Program-Houston 11 (STP-H11) payload at approximately 6:05 p.m. EDT on May 15, ...

This catalog aggregates hundreds of cosmic collisions between pairs of black holes, each producing a new, heavier black hole.

Scientists used some of the most advanced plasma simulations ever created to uncover how the universe builds enormous magnetic fields out of turbulence. The discovery could reshape our understanding ...

Using data from the Webb space telescope, a team of researchers is suggesting that Neptune’s moon Nereid is the only survivor ...

Our galaxy and its nearest large companion, Andromeda, may be headed for a collision on a cosmic scale. What happens then?

Scientists have detected changes in cosmic rays that could reveal the true origin of these extreme particles in the universe.

For decades, astronomers have described the galaxy cluster Abell 2029, a vast city of galaxies in the Virgo constellation, as "the most relaxed clusters in the universe." But beneath that placid ...

Scientists have developed a new technique that could turn black hole collisions into cosmic detectors for dark matter, ...

About 28,000 light-years away, the globular cluster M80 is home to hundreds of thousands of stars bound together by gravity. Crowded environments like this can help drive the growth of black holes ...

Astronomers have spotted a colossal explosion coming from a pair of merging neutron stars lurking within the remnants of an ancient galaxy pileup. The unexpected "collision within a collision" could ...

This artist’s impression shows two tiny but very dense neutron stars at the point at which they merge and explode. ESO/L. Calçada/M. Kornmesser, CC BY Billions of light years away in a remote part of ...
