After more than four years of exploring a menagerie of cosmic happenings through gravitational waves, scientists have finally spotted the third expected variety of collision — twice.

NASA's experimental Mars helicopter has now flown eight times on the Red Planet, traveling farther than scientists hoped would be possible.

The Amazon.com and Blue Origin founder announced on Instagram that he and his brother would fly on the New Shepard vehicle's first crewed flight, scheduled for July 20.

A team of scientists has gotten their best look yet at a gamma-ray burst, the most dramatic type of explosion in the universe.

NASA's Curiosity rover just spotted a strange type of wispy cloud over its Gale Crater home on Mars.

China has released the first photographs taken by its Zhurong rover, which touched down on Mars late on Friday (May 14) as part of the country's Tianwen-1 mission.

A sun-studying spacecraft nabbed its first footage of a solar outburst before its science mission has officially begun.

Scientists have uncovered more details about perhaps the most famous repeating fast radio burst, a mysterious phenomenon astronomers cannot yet explain.

Russia is revisiting its Soviet space heritage for a new series of missions that will take the nation back to the moon.

NASA has delayed the first flight of its Mars helicopter Ingenuity after the vehicle's last test ended earlier than planned.

It took a little help from the full moon to free the massive Ever Given cargo ship from its perch stranded across the Suez Canal.

A U.S. weather satellite that retired eight years ago has fallen apart in orbit, breaking into at least 16 pieces, according to government representatives.

Scientists think they've spied an alien world that lost its atmosphere — then conjured itself a new one.

A year ago, the bright red star Betelgeuse in the Orion constellation hit the headlines for a stark fading episode that astronomers couldn't explain. They still can't, although they keep trying.

Eight years after an asteroid exploded over Chelyabinsk, Russia, scientists are taking advantage of a flyby of the infamous asteroid Apophis to practice protecting Earth from space rocks.

On March 5, wave hello to the most infamous asteroid that won't slam into Earth in 2029. Scientists sure will.

Tackling the climate crisis is one of President Joe Biden's top priorities, and NASA has created a new role to match.

An ongoing investigation of the December collapse of the iconic radio telescope at Arecibo Observatory in Puerto Rico offers early evidence a manufacturing issue may have contributed to the failure.

Three years ago, two neutron stars collided in a cataclysmic crash, the first such merger ever observed directly. Naturally, scientists kept their eye on it — and now, something strange is happening.

The collapse of the iconic radio telescope at the Arecibo Observatory in Puerto Rico last month has left astronomers with a host of questions about what went wrong and what comes next.

Scientists may have detected radio emissions from a planet orbiting a star beyond our sun for the first time.

In a year full of terrible new sorrows and burdens, the collapse of Arecibo Observatory's iconic radio telescope feels like a particularly brutal loss to Puerto Ricans.

Arecibo Observatory is facing a mid-life crisis — or something much worse.

The National Science Foundation (NSF) will decommission Arecibo Observatory's massive radio dish after damage has made the facility too dangerous to repair, the agency announced today (Nov. 19).
