Balancing Act

It could help us make vastly better gravitational wave recordings.

Scientists Say They've Found the Exact Center of the Solar System

A team of astronomers from Harvard University and the Black Hole Initiative developed a new method to hunt for evidence of Planet Nine.

Planet Nein

Is it a gigantic planet five times the size of Earth — or an apple-sized black hole?

Astronomers Want to Figure Out What the Hell Planet Nine Is Once and For All

There is a chance that incoming stars that whip past the Earth could throw it out of orbit and move it away from the Sun, an astrophycisist argues.

Yeet!

Earth would be "doomed to wander the frozen wastelands of our galaxy, with any life on that planet quickly and permanently erased."

Researcher: Passing Star Could Yeet Earth Out of Solar System

Assuming the vacuum of space didn't prevent sound from traveling, what would the Sun sound like? Turns out, it might be rather annoying...

Earful of Sunshine

By this scientist's calculations, the Sun would sound like "10,000 Earths covered in police sirens, all screaming.”

If Sound Traveled Through Space, the Sun Would Be Extremely Annoying

Research teams have discovered dust grains older than our solar system in two meteorites that landed on separate parts of the Earth in 1969.

And both landed on Earth in 1969.

Materials Older Than the Solar System Found in Two Meteorites

New research suggests that a fiery layer of super-hot plasma marks the transition between our solar system and interstellar space.

Access Denied

Voyager 2 broke through, but the wall could make interstellar travel difficult.

Our Solar System Is Blanketed in a Giant Wall of Fire

It's a vision in which humankind has gone off world, built an orbital economy, and then watched it slowly disintegrate, like your hometown after the factory closed. It's hard to say if it's plausible, but it's emotionally resonant.

This Old Town

Applebee's on the Moon. Feral dogs on Mars. Is this the washed-up solar system we deserve?
