There’s more to the universe than meets the eye, he found. His studies led astronomy to the dark side, changing our view of what’s out there.

It’s the most energetic particle of its kind ever discovered, and scientists have no idea where it came from.

President Trump’s executive order is altering scientific exploration across a broad swath of fields, even beyond government agencies, researchers say.

NASA and European scientists explain how they calculate the probability of the space rock 2024 YR4 impacting our planet, and why it’s not yet time to worry.

After the space agency canceled its VIPER rover, an empty space was available on a private spacecraft that will still head to the lunar surface.

The government space agency has vocally promoted diversity and inclusion for decades, even during the first Trump administration.

Researchers say there’s a 1.3 percent chance that the space rock 2024 YR4 could strike our planet — but not until December 2032.

Scientists studying samples that NASA collected from the asteroid Bennu found a wide assortment of organic molecules that shed light on how life arose.

The founder of SpaceX said President Trump had asked his company to return two astronauts aboard the space station to Earth “as soon as possible.” NASA said it would do that “as soon as practical.”

Scientists think a small rock discovered near Earth last August was hurled into space by an ancient impact on the lunar surface.

The president’s Inaugural Address linked landing on the Red Planet with Manifest Destiny, but left many of the specifics unclear.

Home security-camera footage shows a puff of smoke, with the sound of an explosion included, as the space rock lands in Canada. A geologist said it was a rare recording.

While Elon Musk’s spaceflight company repeated a spectacular catch of its powerful booster stage, the upper stage experienced a catastrophic malfunction.

The successful flight to orbit of the Amazon founder’s powerful rocket suggests it could grow into a credible competitor with Elon Musk’s SpaceX.
