For the first time ever, a NASA probe has performed a sample-snagging operation on an asteroid in deep space.
Physicists suggest harnessing the gravitational pull of black holes to create ferocious particle accelerators. The trick? Carefully set everything up so the particles don't get lost forever.
As soon as he saw the data, Paul Chodas knew something was strange about the near-Earth object that had been designated 2020 SO.
An object identified earlier this year as the closest black hole we've ever discovered may have just been demoted.

Only eight countries have signed the Artemis Accords, a set of guidelines surrounding the Artemis Program for crewed exploration of the moon.
The fluid that cushions the human brain redistributes in the skull during spaceflight, according to a new study.
If the Higgs boson really is decaying into pairs of muons in the Large Hadron Collider, that's a big deal for particle physics.
NASA's OSIRIS-Rex spacecraft will "TAG" asteroid Bennu Tuesday (Oct. 20) and collect a sample for return to Earth.
Researchers have found a way to trap and study elusive particle trios called trions at room temperature.
SpaceX is on track to launch its first Mars mission in as little as four years from now, SpaceX's founder and CEO Elon Musk said Friday (Oct. 16) at the International Mars Society Convention.
Some galaxies are swirling blue disks, others are red spheres or misshapen, clumpy messes or something in between. Why the different configurations?
Neutron stars are like the most efficient thermoses in the universe, filled with hot noodle soup. Here's how, over the course of millions of years, they cool down.
Three astronauts made a record-setting jaunt to the International Space Station, and another astronaut already in orbit caught stunning photos of the launch.
A new test of Albert Einstein's theory of general relativity has proved the 20th Century physicist right again, this time using a supermassive black hole.
Two big pieces of space junk are zooming toward a close approach that will occur Thursday (Oct. 15) at 8:56 p.m. EDT (0056 GMT on Oct. 16), according to California-based tracking company LeoLabs.
There's a rising call for "unidentified aerial phenomena" to be studied scientifically, perhaps even using satellites to be on the lookout for possible future events.
Celestron's NexStar 130SLT computerized telescope is on sale for $333.16 for Amazon Prime Day 2020. That's 33% off its regular price.
