All you need is some string.

A spectacular fireworks show will light up an otherwise pitch black universe.

A small, soft smacked into Costa Rica on April 23, 2019. And it carried dust older than our sun, as well as clues regarding how life formed on Earth.

The idea that interstellar object 'Oumuamua is a hydrogen iceberg has a flaw.

Astronomers have bounced lasers of mirrors left by Apollo astronauts on the lunar surface for decades. But this is the first time bouncing one off a lunar orbiter — after a decade of trying.

Astronomers might detect black holes falling into wormholes via ripples in space-time called gravitational waves, a new study finds.

A team of physicists has devised a simple way to measure the duration of a bizarre phenomenon called quantum tunneling.

A new experiment on ultra-rare astatine could open the door to cancer treatments and new research into super-heavy atoms.

Tens of thousands of planets like Earth and Neptune might orbit the giant black hole at the center of the Milky Way.

Telescopes all over the world watched a bright flash light up space around a distant, supermassive black hole. And then, within hours, it was gone.

The United Arab Emirates' probe Hope is on its way to Mars, marking the first planetary science mission led by an Arab country. Here's why.

New research re-examining old data showed that 28 objects previously described as distant galaxies or dim black holes are in fact bright, shrouded supermassive black holes.

One of the most important controversies in physics remains unresolved after a major new study. But at least we have a new precise number for the universe's age.

Physicists are step closer to understanding where the largest black holes in the universe came from. But new data reveals even deeper mysteries around their creation.

The tiniest ticks possible

How much force must a penguin apply in order to blast a flying poop projectile, and how far can it travel? Fortunately for us all, scientists now have answers.

Physicists have discovered a new, exotic kind of tetraquark, made up of four charm quarks. They say it's a major breakthrough.
