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.

New images show a glowing "dashed" line in the night sky above Arizona after part of a SpaceX Falcon 9 rocket fell back to Earth following a double-header launch.

The ancient obect Gz9p3, which appeared as a single point of light through the Hubble Space Telescope, is actually one of the most enormous galaxies in the early universe, James Webb Space Telescope observations reveal.

A large swirl of white light that temporarily outshone vibrant auroras in the Arctic last week was triggered by the death throes of a SpaceX rocket that deployed more than 50 satellites into space.
