If you live in Vermont and heard an explosion just before dinnertime Sunday (March 7), there's a good chance that was a shockwave from an incoming meteor exploding over the state.

Black holes may not be black or holes, a new theory proposes.

Scientists want to use it to learn more about the sun and nuclear fusion.

Astrophysicists have a wild idea to explain the bizarre abundance of super-high-energy radiation shooting from the center of our galaxy: gravity portals.

Could this finally confirm whether a piece of her plane has been found?

Like mad scientists, researchers are creating miniature black holes in their laboratories. Their mission? To see if a mysterious form of radiation predicted by Stephen Hawking exists.

Astronomers spot two highly delayed signals from two different black holes tearing apart stars in their vicinity.

Cosmologists simulated 4,000 versions of the universe in order to understand what its structure today tells us about its origins.

Scientists have spotted the first evidence of a rare Higgs boson decay, expanding our understanding of the strange quantum universe.

There's a dwarf planet in our solar system, far beyond the orbit of Pluto, that swings so far away from the sun that from its perspective Earth and Saturn look like neighbors.

When the plasma of the Van Allen belts drops in density during a solar storm, it can set up the perfect conditions for electrons to travel nearly as fast as light.

The mystery at the heart of an unexplained, bright point of gamma-ray light in the sky has been solved: a violent, whirling redback.

A weird, super-powerful particle that's not truly a particle could have dominated the universe when it was just a second old, releasing a flood of ripples that permeated all of space-time.

Scientists are finally figuring out how much dark matter — the almost imperceptible material said to tug on everything, yet emit no light — really weighs.

In 2018, one of the brightest X-ray lights in the sky went dark, and scientists still aren't sure why.

Scientists captured high-speed footage of the moment before lightning strikes.

It's now possible to send uncrackable quantum messages through thin air, and the people who figured out how to do it are getting ready to send the messages into space.

A mysterious "kick" in the early universe may have produced more matter than antimatter. And that imbalance may have also led to the creation of dark matter, researchers now say.
