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.
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.
In our neighborhood, three quarters of planets have at least one moon, but no such object has been confidently discovered so far in distant star systems — such worlds are just too small and far away.
Three space agencies have pulled together data monitoring the global impact of the COVID-19 pandemic into one joint information source in hopes of assisting understanding of the public health crisis.
A new commercial agreement marks a step forward in the quest to add a new module to the International Space Station — one that will become an independent space station after the massive lab's tenure.
Relativity Space has signed agreements for a new launch site and a new batch of launches destined to blast off from that site.
Astrophysicists have spotted the strangest gravitational-wave signal yet, an observation that could force scientists to rewrite what they know about the cosmos.
Last year, NASA set itself an ambitious goal: Send astronauts to walk on the moon in 2024. Now, the agency is busy planning what astronauts will do during those excursions.
A "ring of fire" solar eclipse crossed over Africa and Asia this weekend, and the view from space was spectacular.
Incredible new images from the Hubble Space Telescope reveal nearly dead stars spewing blasts of hot gas into deep space in strange but stunning ways.
A spacecraft that launched a quarter century ago to study the sun has discovered its 4,000th new comet in a spree of serendipitous science.
NASA is ready to take its first spin at flying a helicopter on another world as the agency's Mars helicopter, Ingenuity, prepares for launch in July.
