A new report from the Commercial Space Federation warns that China could soon overtake the U.S. in the "new space race." The country's rapid progression starkly contrasts the limitations imposed on NASA by record-breaking budget cuts.

A new NASA study suggests that solar activity will remain high or rise further in the coming decades, contradicting previous assumptions that the sun was quieting down — and scientists "don't completely understand" why.

The "potentially hazardous" asteroid 2025 FA22 will fly close past Earth at more than 24,000 mph on Thursday (Sept. 18). The space rock was previously predicted to have a slim chance of impacting our planet in 2089, temporarily earning it the top spot on a major risk list.

A new analysis of asteroid Ryugu hints that the "potentially hazardous" space rock once had flowing water in its core, possibly leftover from the impact that created it.

New photos captured during the recent "blood moon" total lunar eclipse show that the interstellar comet 3I/ATLAS may be turning green as it gets closer to the sun.

NASA's Perseverance rover has photographed a peculiar rock formation that looks eerily like a turtle poking its head out from its protective shell.

A giant S-shape structure, around 10 times wider than Earth, recently appeared in the center of the sun, moments before our home star unleashed an even larger plume of plasma that later crashed into our planet.

New images reveal interstellar comet 3I/ATLAS beginning to grow a signature tail as it zooms closer to the sun ahead of a close encounter with Earth this fall.

New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — containing the equivalent magnetic energy of a human brain.

"Marsquake" data collected by NASA's InSight lander have revealed dozens of mysterious blobs within the Red Planet's mantle. The structures may have been left by powerful impacts up to 4.5 billion years ago.

Asteroid 2025 QV5, which was first spotted in late August, will make a close approach to Earth on Wednesday (Sept. 3). It will not get this near to us again until Sept. 4, 2125.

Space weather experts warn that a "strong" geomagnetic storm will rock Earth on Sept. 1-2, potentially lighting the skies with vibrant auroras across large parts of North America. The disturbance is being triggered by a rare, cannibalistic ejection from the sun.

New models suggest that Ceres, the asteroid belt's largest object, once had a radioactive core that could have sustained life in the dwarf planet's hidden subsurface ocean billions of years ago.

The solar system has many more moons than the one we can see in the sky. But how many do we actually know about? And how many more are waiting to be discovered?

New data from the James Webb telescope suggests that Bennu and Ryugu — two asteroids recently visited by sample-return missions — are both fragments of a single massive "parent".

Chinese astronomers have spotted a hidden supermassive black hole in the background of a peculiar gravitational wave event from a black hole merger, hinting that all three singularities were locked in a never-before-seen triple system.
