NASA's Swift space telescope has resumed science observations after a private mission failed to boost its decaying orbit, making the most of its remaining time in space.
"This isn't what we expected at all."
Spaceflight can do strange things to the human body — including making it harder for astronauts to poop.
Water and cosmic dust can survive in the harsh environment near Sagittarius A*, new observations reveal.
"It's part of the fabric of astronomy research now."
Astronomers have nearly doubled the number of known cosmic X-ray sources.
While the impact itself probably won't be visible from Earth, observers may have a chance to spot a plume of debris rising above the lunar surface.
A new analysis of NASA's Spirit rover data reveals overlooked traces of crystalline hematite and altered magnetite.
Astronomers found seven rare quasar gravitational lens candidates using AI, providing a powerful new tool for studying black hole and galaxy evolution.
The subsurface findings could transform how scientists study volcanoes across the solar system — including those on Earth.
SpaceX's 13th Starship test flight will carry out the first deployment of Starlink V3 satellites while testing booster recovery and upgraded flight systems in a key step toward operational missions.
Astronomers discovered that a near-Earth asteroid is actually a comet that could help scientists identify more hidden comets and improve planetary defense.
A new study suggests the most extreme solar storms to strike Earth could have greater impacts on satellites, power grids and communications than previously thought.

As the United States prepares to celebrate its 250th anniversary, the history of the solar system tells its own story of exploration.
A bizarre "bow-and-arrow" radio galaxy nearly 1.8 million light-years across could reveal how galaxy clusters sculpt some of the universe's largest structures.
A new exoplanet model screens rocky worlds by their ability to retain atmospheres over geologic timescales, helping narrow the search for potentially habitable planets beyond Earth.
Powerful outflows of gas may explain why so many massive galaxies shut down star formation soon after the Big Bang.
The asteroid impact that triggered the extinction of the dinosaurs may also have created one of Earth's most enduring habitats for life.
Euclid space telescope observations of ancient globular cluster NGC 6397 reveal a subtle gap in brightness distribution of red dwarf stars.
