Asteroid "2021 FO6" is expected to whiz by the Earth on March 27 at around 28,028 miles per hour.

"Neptune was the missing piece of the puzzle when it came to detecting auroras on the giant planets," said the European Space Agency.

"We report the discovery of one of the most distant galaxies known to date," astrophysicist Joris Witstok told Newsweek.

Scientists have found unusual, blueberry-like rocks on Mars that could give us more insights into its geological history.

The 19-year mystery of the "fuzzy object" seen at the helical outflow's base has been solved.

The light show may be visible from up to nine states Tuesday evening, according to NOAA forecasts.

"The universe still holds surprises beyond our imagination," astrophysicist Shankar Ray said.

"Unlike any objects we know, these filaments really surprised us," said astronomer Kai Yang.

Asteroid "2021 FH1" is set to whizz pass the Earth on March 21 at a zippy 30,959 miles past hour.

The 700–1,300 feet-wide space rock deformed rocks more than six miles from the impact site when it hit 600 million years ago.

A carrier rocket and a spacecraft are always on standby on the ground to rescue astronauts aboard the Chinese space station.

The latest discovery marks the furthest detection of oxygen ever made and defies what we thought about how galaxies formed in the early universe.

A senior official warned the U.S. risks losing its edge in space as strategic adversaries continue making gains at "an eye-watering pace."

Astronauts Barry Wilmore and Sunita Williams didn't receive any overtime or holiday pay during their 286-day stint in space.

"Maybe the universe is telling us it's more complicated than we thought," said cosmologist Andrei Cuceu.

"This has been a decade-long detective story, with each recorded meteorite fall providing a new clue," said one astronomer.

A giant spiral galaxy may rewrite what we know about the early universe's formation.

Living aliens? Maybe not. But there are two other options he's considered.

The SpaceX owner was speaking with Texas Senator Ted Cruz about the early days of the company.

"The universe surprises us with mysteries we didn't expect," said astronomer Grant Hill.

The idea, physicist Naman Kumar says, may "illuminate some of the deepest mysteries in cosmology."

When Butch Wilmore and Suni Williams splash down off the coast of Florida Tuesday evening, the biggest winner in their nine-month ordeal will be none other than Elon Musk.

The space agency has been tracking asteroid 2025 DU25. Here's everything you need to know.

Vladimir Putin's special envoy said that discussions with Elon Musk could take place "in the near future."

NASA astronauts Sunita Williams and Butch Wilmore will return to Earth after nine months in space.

The new images—of when the cosmos was a mere 380,000 years old—show the "first steps towards making the earliest stars and galaxies."

Often seen as destructive, supermassive black holes could help sustain life under specific conditions, scientists have found.

NASA astronauts Suni Williams and Butch Wilmore have finally returned to Earth after 9 months aboard the ISS. Newsweek's live blog is closed.

Butch Wilmore and Suni Williams, who initially launched aboard Boeing's Starliner capsule, are traveling home.

Newsweek previously reported China's involvement in an observatory in South America that researchers said could be used to "support military space operations"
