Every winter, when sunlight hits at the right angle, visitors to Virginia's First Landing State Park are treated to a mesmerizing rainbow light show courtesy of the park's bald cypress swamp.

Finding the universe's brightness is essential for confirming our theories of what makes up the universe. But to do so, scientists had to send a spacecraft far away from our sun.

New theoretical research finds that it's impossible to form a black hole with the energy of light particles alone, poking a hole in Einstein's theory of general relativity.

In the dark, vivid colors seem to fade to gray and they're hard to tell apart. Why is that?

Aurora-hunting photographers were surprised to spot a misshaped SpaceX spiral with ethereal horns over Europe during a recent geomagnetic storm.

Researchers have discovered a way to curve data-carrying terahertz signals around obstacles, paving the way for ultrafast 6G.

Artificial intelligence trained by asteroid-hunting citizen scientists helped identify more than 1,000 never-before-seen solar system objects from old Hubble images spanning two decades.

Researchers have found an elemental physical interaction between light and magnetism that might lead to the next generation of computing memory.

New data suggest that exoplanet WASP-76 b could harbor a massive, rainbow-colored light show known as a "glory." Until now, this phenomenon has been seen only within our solar system.
