Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of ...

In our three-dimensional space, elementary particles neatly filter into either bosons or fermions. But in lower dimensions, that distinction gets a bit murky.

Supernova 1987A appeared in the far-southern constellation of Doradus (the Swordfish), in which the Large Magellanic Cloud is ...

Five scientists from Lawrence Berkeley National Laboratory (Berkeley Lab) have received Early Career Research Program (ECRP) awards from the ...

Something genuinely strange has just happened in fundamental physics: an underground neutrino telescope in the Mediterranean ...

Astronomers have witnessed a rare cosmic event: a massive star that didn’t explode in a spectacular supernova, but instead quietly collapsed into a black hole.

New optical modules have now been added to the IceCube Observatory, allowing it to measure lower-energy neutrinos as well.

A brilliant star in our nearest galactic neighbor didn’t go out with a bang, it simply faded from sight, leaving scientists to piece together what could make something so massive vanish so quietly.

It was a bold thought experiment: that only one electron makes up the entire universe. The most famous conversation about it took place between Richard Feynman, PhD, and John Wheeler, PhD, both ...

This enormous chain of hundreds of galaxies—a cosmic filament—is twisting through space 400 million light-years away ...

The shape of the cosmos depends on a balance of two competing forces: the pull of gravity and the expansion driven by dark ...

New data from major dark-energy observatories suggest the universe may not expand forever after all. A Cornell physicist calculates that the cosmos is heading toward a dramatic reversal: after ...
