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.

After a nail-biting 27 minutes, the United Arab Emirates' (UAE) first-ever interplanetary mission has successfully reached orbit around Mars.

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).

SpaceX CEO Elon Musk has announced that he has received mixed results from tests meant to diagnose infections of the novel coronavirus.

The famed Arecibo Observatory in Puerto Rico has suffered another major blow in a difficult year that has seen two snapped cables damage the fragile dish.

Scientists think they have identified a lava world so dramatic that it might boast a thin regional atmosphere of vaporized rock where it is closest to its star.

What goes up must come down — including, sadly enough, the International Space Station.

Scientists can now catch gravitational waves better than ever before.

As soon as he saw the data, Paul Chodas knew something was strange about the near-Earth object that had been designated 2020 SO.
