Comet 3I/ATLAS is extremely irradiated from billions of years of cosmic ray bombardments, new research using observations from the James Webb Space Telescope (JWST) has revealed. The comet has soaked ...

Deep inside a nearby galaxy, a black hole sits behind a thick wall of dust. Almost all its light gets trapped.

EAST LANSING, Mich. – New research published by Michigan State University astrophysicists could help scientists answer a century-old question: where did galactic cosmic rays come from? Cosmic rays – ...

New James Webb Space Telescope observations suggest that organic molecules are much more common outside our galaxy than previously believed.

The traditional astrophysical recipe for life as we know it is quite simple: Get a rocky, gas-shrouded world in a “habitable zone” orbit around a star so that it’s not too hot or too cold. Then just ...

Life on Mars sounds like something from a "Doctor Who" episode. But a study published in the International Journal of Astrobiology challenges the science fiction notion of that idea. The research ...

Ultra-high-energy cosmic radiation as a research area investigates cosmic rays with energies typically above 10¹⁸ eV, focusing on their origins, acceleration mechanisms, propagation through ...

An international research team led by scientists from the Technion – Israel Institute of Technology has achieved the first direct measurement of cosmic rays deep inside a star-forming nebula. Using ...

High energy astrophysics probes the most energetic phenomena in the Universe, from explosive supernova remnants to the powerful outflows near compact objects. A central focus of this field is the ...
