Five astronauts living in space are preparing to welcome a new shipment of supplies after an evening launch from Kazakhstan of an uncrewed Progress cargo vehicle.

The United Arab Emirates is on its way to Mars, claiming the title of first Arab country to launch an interplanetary mission, which it designed and built in just six years and dubbed Hope.

Life on Earth can seem pretty hazardous, but if you ask astrophysicist Paul Sutter, it's still safer than anywhere else in the universe.

On the 51st anniversary of the Apollo 11 moon landing, the Google doodle program chose to commemorate the scientific legacy of Turkish astrophysicist Dilhan Eryurt.

The United Arab Emirates is bound for Mars.

A mission called Hope, the Arab region's first attempt to go interplanetary, is now on its way to Mars.

The United Arab Emirates is sending a spacecraft called Hope to Mars in what will, if successful, become the first interplanetary mission based out of the Arab region.

What does it mean when a black hole suddenly stops gobbling up gas completely — and then just as suddenly starts again, hungrier than ever?

A historic Mars launch has been delayed again by troublesome weather conditions at the launch site.

It took just one round of photographs from a new solar science spacecraft for scientists to learn something new about the sun.

The launch of the UAE's first Mars mission Hope was delayed to July 16, a two-day slip, due to bad weather at its Japanese launch site.

A nagging problem with planets is that they are just so large: Send a spacecraft to one patch of a planet and inevitably, some of the things you learn will apply only right there.

NASA wants to go to the moon, and astrophysicists want their instruments to ride along too.

A daring sun-grazing NASA spacecraft turns its focus to Venus today (July 10) with a critical flyby that will pass through the planet's weird "tail."

Each year, dust from the Sahara Desert blows off Africa and across the Atlantic, but most years that plume isn't so massive it's nicknamed "Godzilla."

Next week, the United Arab Emirates will launch its first-ever interplanetary mission, a Mars orbiter that the nation hopes will inspire the region and advance Red Planet science.

Studying Mars has been by turns tantalizing and heart-breaking, a constant dance as improving technology builds or dims hopes of finding life on our red neighbor.

Astronauts caught a stunning natural light show this weekend from a comet that has been dazzling skywatchers on Earth as well.

A high-powered telescope array has caught the brilliant fireworks-like "streamers" of gas formed during an early stage of star development in a cluster.

The coronavirus pandemic has slowed testing of NASA's next megarocket, but the monthslong process is resuming and has checked off a key milestone: powering up the core stage.

Cubesats have revolutionized orbital science, and a rover counterpart may soon do the same for surface science, beginning on the moon.

Two incredibly strange celestial objects whose discoveries trace, in part, to observatories at the summit of Maunakea now carry the peak with them in official names inspired by Hawaiian culture.

One is blinding white and the other a dull, dusty red. But both are cold, barren worlds, difficult to reach and full of tantalizing scientific mysteries.

It's right there in the name: black holes aren't supposed to produce flashes of light. But scientists think that last year, they spotted black holes doing just that.

A U.S. space tourism company has booked two passenger seats on a Russian Soyuz capsule headed to the International Space Station in 2023, and one of those tourists will take part in a spacewalk.
