The quarks inside atoms move slower than the quarks inside free-floating protons and neutrons. But why?
The new experiment demonstrated a bizarre quantum effect from the double-slit experiment at an unprecedented scale.
The Higgs boson appeared again at the Large Hadron Collider (LHC), and this time, it revealed something new and exciting about its behavior.
If the Higgs boson really is decaying into pairs of muons in the Large Hadron Collider, that's a big deal for particle physics.
This supermassive black hole's spin has been measured for the first time, and it's surprisingly low.
The most remote particle detector on Earth has detected the most energetic antimatter neutrino ever, confirming a 51-year-old prediction.
At some point in the next few weeks, the U.S. plans to fire an extreme, hypersonic weapon. The question remains: What's the point?
If you live in Vermont and heard an explosion just before dinnertime Sunday (March 7), there's a good chance that was a shockwave from an incoming meteor exploding over the state.
Does the solar system really have a big, dark ninth planet drifting somewhere far beyond the orbit of Neptune? A new paper argues that Planet 9 is a statistical mirage.
The mystery at the heart of an unexplained, bright point of gamma-ray light in the sky has been solved: a violent, whirling redback.
It's a busy February for Mars, with three probes from three separate space agencies arriving at the red planet over the course of just nine days. Here's why.
Sea levels will probably rise faster than the most mainstream climate models predict, according to a new study.
In 2018, one of the brightest X-ray lights in the sky went dark, and scientists still aren't sure why.
It's now possible to send uncrackable quantum messages through thin air, and the people who figured out how to do it are getting ready to send the messages into space.
Ever ridden a teacup ride at a state fair? If so, you might have a small taste of life in a whirling, twirling sextuply-eclipsing sextuple star system.
Data from the now-destroyed Arecibo radio telescope has revealed a bizarre new type of hybrid venomous spider star.
Harvard astrophysicist Avi Loeb has reignited a debate about whether alien life can explain an object that visited the solar system in 2017 in a scathing new book.
A new study shows that due to pollution already released, Earth will eventually blow past Paris goals. But that doesn't mean all is lost.
If there are other intelligent civilizations in the Milky Way, they are probably much closer than we are to the galactic center, and fairly young.
There's a giant asteroid somewhere out there in the solar system, and it hurled a big rock at Earth that left behind meteorites unlike any scientists had ever seen.
Astronomers hunting for radio signals from alien civilizations have reportedly detected an "intriguing signal" from the direction of Proxima Centauri, the nearest star system to the sun.
Did the creator of the universe leave a hidden message in the cosmos for intelligent life? If so, scientists have yet to find it. But at least one is still trying.
