After a three-year nap, the world's largest atom smasher is waking up and getting ready to smash atoms harder than ever.
On the surface, a galaxy 250 million light-years from Earth seems like any other, but a deeper look reveals a puzzling quirk: It seems to have no dark matter.
Scientists figured out what slammed into Earth and killed the dinosaurs 66 million years ago: a giant dark primitive asteroid from the outer reaches of the solar system's main asteroid belt.
Scientists have recreated the first matter that appeared after the Big Bang in the Large Hadron Collider.
An ultra-high-resolution simulation of a tiny slice of the universe — a million times smaller than a proton — has revealed the very first structures to ever exist.
A new study suggests that annihilating dark matter particles may explain the Milky Way center's mysterious glow.
Astronomers have searched the entire Milky Way to identify the safest places to live. It turns out, we're in a pretty good spot.
Tiny snowflakes of radioactive uranium that trigger massive nuclear blasts might explain some of the universe's more mysterious star explosions.
A new study on the rotation of the universe's first light could suggest physicists need new rule-breaking subatomic particles
Astronomers have discovered four faint objects that at radio wavelengths are highly circular and brighter along their edges. And they're unlike any class of astronomical object ever seen before.
For the first time, a Polish group has identified two nearby stars that seem to have plucked up their icy partners, swinging them into orbits around our sun.
If you look around space, you'll notice a lot of things — the planets, stars, moons, even the galaxy itself — have one thing in common: they're spinning. So, is the universe spinning, too?
Measures of the universe's expansion taken from different sources don't match. An exotic form of dark energy particles could be the reason why.
These photons have trillions of times more energy than a garden variety light particle coming from the sun.
Black holes are engines of destruction on a cosmic scale, but they may also be the bringers of life.
