The growing list of “firsts” for Perseverance, NASA’s newest six-wheeled robot on the Martian surface, includes converting some of the Red Planet’s thin, carbon dioxide-rich atmosphere into oxygen....

We're still trying to understand the mechanics that allow a star to self-destruct....

As the New Horizons spacecraft hurtles out towards interstellar space, it has now reached an historical milestone. On April 17, 2021, New Horizons passed 50 astronomical units, or 50 times Earth’s distance from the Sun. It is just the 5th spacecraft to reach …...

In a world first, researchers from the Okinawa Institute of Science and Technology Graduate University (OIST) have captured an image showing the internal orbits, or spatial distribution, of particles in an exciton—a goal that had eluded scientists for almost …...

NASA announced on Wednesday that its highly-anticipated SpaceX Crew-2 launch to the International Space Station is delayed....

Fifty years ago, NASA's Apollo 14 completed the third crewed mission to the moon. On board the spacecraft as it landed in the Pacific Ocean on February 9, 1971, was some unusual cargo -- about 500 tree seeds....

The fossilized shoulder joint of an early hominin named “Little Foot” suggests the upright-walking species was also proficient at swinging through trees, at a skill long gone among modern humans....

Ongoing global warming is likely to cause tipping point thresholds to be passed, but an abrupt system change can still be avoided if the warming is reversed quickly relative to the timescale of the tipping element....

Origami-inspired multistable structures that can be inflated from flat to three dimensions have been designed; a library of foldable shapes is created and then combined to build metre-scale functional structures....

The highlight of the new chart is a wake of stars, stirred up by a small galaxy set to collide with the Milky Way. The map could also offer a new test of dark matter theories....

Biodegradable plastics have been advertised as one solution to the plastic pollution problem bedeviling the world, but today's "compostable" plastic bags, utensils and cup lids don't break down during typical composting and contaminate other recyclable plasti…...

In a battle that came down to costs, SpaceX's unique model won the day....

Over 4,000 exoplanets — alien planets orbiting other stars — have been found by astronomers so far. There are a variety of ways to find them, most of which use indirect methods, but one of the coolest is quite direct: Getting actual images of the planets near…...
