In physics terms, radiation is simply energy on the move, carried by waves like sunlight or particles like those released by ...

Soon, tentative evidence did emerge: there was a hint, inside each bubble, of a thin gamma-ray jet pointing back towards the galactic center.

Using a combination of telescopes, astronomers have characterized the closest supernova linked to a fast X-ray transient. The ...

Now, researchers have experimentally shown that amino acids could have formed in these early meteorites from reactions driven by gamma rays produced inside the space rocks.

The first gamma-ray bursts were discovered by accident in the 1960's, by spy satellites looking for gamma-rays from secret nuclear bomb tests.

Researchers have found clouds of cold gas embedded deep within larger, superheated gas clouds—or Fermi bubbles—at the Milky ...

Back in 2010, scientists spotted something shocking: a pair of gigantic, glowing lobes of gas bursting from the Milky Way’s ...

Now, researchers reporting in ACS Central Science have experimentally shown that amino acids could have formed in these early meteorites from reactions driven by gamma rays produced inside the ...

A glowing blob known as “the cocoon”, which appears to be inside one of the enormous gamma-ray emanations from the centre of our galaxy dubbed the “Fermi bubbles”, has puzzled astronomers since it was ...
