In the early universe, primordial black holes could acquire a "dark charge," giving them an unnaturally long lifetime, new research suggests. This makes them an interesting candidate for dark matter.

This approach can now be used to determine the rotation rate of any celestial object with a magnetic field and auroras — including exoplanets.

A bright star located in the Milky Way appears nestled in the distant galaxy NGC 5530 due to a chance alignment along the Hubble Space Telescope's line of sight.

In 23 billion years, these two white dwarf stars will collide. Then, they'll explore. Here's why scientists say this discovery is such a big deal.

A sudden stratospheric warming event reversed the winds that make up the northern polar vortex on March 9. A new animation shows the vortex also moved away from the Arctic towards Europe.

Extraordinarily powerful light from gamma-ray bursts might help produce heavy elements from the outer shells of dying stars.

Seismic mapping of North America has revealed that an ancient slab of crust buried beneath the Midwest is causing the crust above it to "drip" and suck down rocks from across the continent.

Scientists are probing stellar "quakes" to understand what lies beneath the surface of a star's body.

"OK, this is kind of out there and caters to your inner Uber-Geek."

The near-Earth asteroid 2025 BC10 will pass safely near our planet on Saturday (April 5). The Virtual Telescope Project will livestream views of the asteroid's close approach online.
