A few scant equations can explain a variety of phenomena in our universe, over vast gulfs of space and time. Here's a taste of just how powerful modern physics can be.
For the past few years, the possibility of a new (and big!) planet hanging around in the far outer solar system has tantalized scientists and the public alike. Is "Planet Nine" out there or not?
A physicist proposes that the moon is a great place to build a particle collider and conduct high-energy physics experiments.
Physicists are figuring out how close you can get to a black hole before you are unlikely to escape. That threshold is called the innermost stable circular orbit (ISCO).
Magnetars — highly magnetized, rapidly rotating super-dense stars — are among the most enigmatic creatures to inhabit the cosmos and their origins are shrouded in mystery.
We all know that iconic scene: Luke Skywalker staring forlornly — and perhaps wistfully — at the double sunset of his home planet, Tatooine.
String theory is a purported theory of everything that physicists hope will one day explain … everything.
It was a big moment for our cosmos when the first stars awoke, but it's an elusive one for scientists.
String theory is a powerful idea, unfinished and untested, but one that has persisted for decades despite inauspicious beginnings.
Researchers recently released simulations of the Large Magellanic Cloud — a satellite galaxy of the Milky Way — and found that cosmic rays from a starburst event are starting to rip it apart.
The world of the teensy-tiny, the quantum realm, could have a favorite flavor. Here's why that's a big deal.
A new study has called into question the prevailing notion that the universe is "flat." The stakes of this cosmological debate are huge.
At some point, the rules of the subatomic give way to the rules of the macroscopic. But how? We're not exactly sure, and it's been a long, strange journey in trying to answer that question.
An ambitious new fleet of spacecraft could reveal whether space-time is smooth or chunky, and in doing so the ultimate nature of reality.
You're about to take a dip into the inky blackness of a giant black hole and see what's on the other side of that enigmatic event horizon. What will you find inside? Read on, brave explorer.
A brand-new particle has possibly emerged and is altering the future destiny of our entire cosmos, a physicist says.
