Cosmic rays, born from distant exploding stars, produce muons that shower Earth and penetrate stone like ghosts. These ...

How is lightning initiated in thunderclouds? This is difficult to answer – how do you measure electric fields inside large, dangerously charged clouds? It was discovered, more or less by coincidence, ...

Stellar black holes form from the collapse of massive stars at the end of their lives, typically weighing 3 to 50 times the mass of the sun. When a star runs out of fuel, it explodes in a supernova, ...

Dark matter is a ghostly substance that astronomers have failed to detect for decades, yet which we know has an enormous influence on normal matter in the universe, such as stars and galaxies. Through ...

The last gasp of a primordial black hole may be the source of the highest-energy “ghost particle” detected to date, a new MIT study proposes. In a paper appearing today in Physical Review Letters, MIT ...

Cosmic rays are particles from outer space that travel across the universe. They can be made by the sun, by other stars exploding, and even black holes. They move extremely fast, nearly the speed of ...

Dark matter, if it exists, is probably in the latter category. If hypothetical weakly interacting massive particles (WIMPs) are real, their collisions with regular matter may have left fossil traces ...

ON A clear night, watching the stars in an inky sky, one word comes to mind: calm. The starlight seems to speak of stability and permanence. And yet, hidden from the naked eye, the wider cosmos is a ...

How often do black holes explode? New research refines old calculations, hinting that black hole explosions may be a once-in-a-decade occurence. When you purchase through links on our site, we may ...
