See a pair of superheavy neutron stars collide in this simulation with gravitational wave audio. "An audible tone and a visual frequency scale (at left) track the steady rise in the frequency of ...

The bold question-askers at What If warn how a black neutron star could destabilize Earth’s orbit and wreak havoc.

The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses. They definitely exist in East Lansing, Michigan.

Figuring out the ages of stars is fundamental to understanding many areas of astronomy—yet, it remains a challenge since ...

Astronomers studying the remnant SNR 0509-67.5 have finally caught a white dwarf in the act of a rare “double-detonation” supernova, where an initial helium blast on the star’s surface triggers a ...

These scientists may be lesser known than Einstein and Newton, but they made giant contributions to science, including astronomy, physics, chemistry and medicine. Isaac Newton once wrote, "If I have ...
