Cosmic X-ray flashes are a phenomenon when the night sky seems calm to the naked eye but in the electromagnetic spectrum. The ...

Scientists still don’t know where ghostly particles called neutrinos originate. A distant galaxy could be a potential source.

A peculiar cosmic event, dubbed EP240305a, has baffled astronomers with its rapid X-ray fade and lingering radio signals.

A study published in Physical Review Letters by a research team at Penn State University offers a potential explanation. Led ...

Cosmic rays traveling through space may provide enough energy to sustain life even in incredibly cold and dark environments, a new study suggests. The staggeringly energetic neutrino likely came from ...

Millions of light-years away, millions of years ago, a star exploded. In this violent process, it ejected incredible amounts ...

There are multiple ways to form black holes. The one most commonly taught in high school physics classes is that they are ...

Cosmic rays are relativistic charged particles that pervade the Galaxy and beyond, carrying crucial information about violent astrophysical processes and influencing the dynamics of interstellar and ...

Michigan State University astrophysicists are closing in on one of space science’s biggest mysteries: where the galaxy’s most energetic particles come from. Their studies uncovered a pulsar wind ...

The mysterious Amaterasu particle may not be a proton at all. New research suggests that some of the most extreme cosmic rays could be ultraheavy atomic nuclei, heavier than iron, which are better ...
