Edie Widder sat quietly in the dark for half an hour. All around her, critters floated and glided by as she peered through the thick glass bubble of a submersible, perched on a rocky ledge nearly ...

Remarkable backyard footage captures giant solar prominence and streams of coronal rain flowing along the sun's magnetic ...

Like fireflies and many deep-sea creatures, certain fungi can naturally emit light through bioluminescence pathways in which specialized enzymes convert chemical energy into visible light. Medical ...

Multiple videos show a rare "fireball" meteor breaking apart with a flash of emerald light over the erupting Mount Mayon.

CERN’s Super Proton Synchrotron has a resonant “ghost.” Using mathematics, physicists measured and modeled how these resonant lines intersect. Modeling a 3D shape over time requires a 4D system of ...

You may have seen pictures of blue, glowing beaches under a dark sky. This glow is called bioluminescence. It is emitted by tiny organisms called bioluminescent algae that live in the water.

The universe may have its own version of Heisenberg's uncertainty principle, and that might be enough to explain dark energy without invoking any new physics at all.
