For over 40 years, astronomers have been puzzled by strange X-ray signals from the Helix Nebula’s white dwarf. Now, they may ...

Scientists suspect lightweight dark matter might ionize hydrogen in the Milky Way’s core. This could also explain the 511-keV ...

The most powerful cosmic rays in the universe currently have no explanation. New research suggests that exotic, ...

Blazars are active galaxies that emit narrow jets of ionized matter from their centers, aimed towards Earth. Depending on ...

Opinion High energy neutrinos are the coolest particles in astrophysics. Born in distant cosmic cataclysms, they speed ...

XRISM has uncovered how galaxy clusters evolve—violent mergers create turbulence, preventing hot gas from cooling. This ...

For years, astronomers have searched for the origins of ultra-high-energy cosmic rays, the most powerful particles in the universe. These energetic travelers move at nearly the speed of light, packing ...

The X-ray signal from WD 2226-210 is similar to the X-ray emissions of two other white dwarfs that do not sit within cocoons ...

"We would like to understand the difference between these systems, which holds the clue to understand just how many cosmic rays are produced in the jets of microquasars." Using 16 years of data ...

Astronomers led by Stanford University and Harvard believe the "remarkable" cosmic explosion could either be the first X-ray burster ever discovered in the Large Magellanic Cloud (LMC), a rare ...

ESA’s Integral observed space for 22 years, uncovering gamma-ray bursts, black holes, and gravitational waves.

So their deep dive into the very beginning of life as we know it revealed that water was born from epic rays of light about ...
