A hypothetical particle known as the ultralight boson could be responsible for our universe's dark matter.

If teensy black holes could be produced inside the world's largest atom smasher, the Large Hadron Collider, that would be a boon for physics.

What if black holes aren't black holes at all, but rather the cosmic equivalent of fuzzy, vibrating balls of string?

Black holes shorn of event horizons could lurk throughout the universe.

The EmDrive doesn't just violate our fundamental understanding of the universe; the experiments that claim to measure an effect haven't been replicated. When it comes to the EmDrive, keep dreaming.

A pair of astronomers is advocating a daring new research program: to turn our widening search for life beyond Earth into a hunt for dark matter.

Our sun's death is a long way off — about 4.5 billion years, give or take — but someday it's going to happen, and what then for our solar system?

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.

In one upside-down, hypothetical version of the universe, a bizarre type of black hole could exist that is stranger than an M.C. Escher sketch: charged black holes.

Black holes can get big … really big. But just how big? It's possible they could top out at over a trillion times more massive than the sun.

A recent survey sheds some light on what the mighty Aztecs thought about the rare and wonderful solar eclipses.

The giant planet's long-ago migration likely had big impacts.

Of all the rocky, inner worlds of the solar system, Venus is the most challenging to explore.

For all the biological activity on our homeworld, we're not the only interesting planet orbiting the sun. There are some other equally amazing places in the solar system. Here is just a sampling.

All you need is some string.

Hair may record the information swallowed by the gravitational monsters.

Some patience will be needed.

Astronomers recently spotted perhaps the strangest white dwarf yet: a dead star the spins twice a second, sucking down material from a nearby companion as it goes.

Sure, space looks pretty, but just because it sparkles doesn't make it welcoming.

Life on Earth can seem pretty hazardous, but if you ask astrophysicist Paul Sutter, it's still safer than anywhere else in the universe.
