Every day, about 48.5 tons of space rock hurtle towards Earth.

The skies may be full of invisible "boson stars" that could have a connection to dark matter.

Buttes and mesas in Mars' Chryse Planitia contain clay minerals made from liquid water interacting with the rock nearly 4 billion years ago.

Images captured by NASA's Solar Dynamics Observatory have revealed that "coronal loops" give off subtle flashes of ultraviolet light before a solar flare, which could act as an early warning system for dangerous space weather.

If parallel universes exist, can we access them? Let's explore the possibility.

With winds blowing at 20,500 mph, "the planet has complex weather patterns just like Earth and other planets of our own system," scientists said.

A new analysis of M87*, the first black hole imaged by humanity, has revealed turbulence in the matter around it, which this supermassive black hole feasts upon.

A study of volcanic cones near the equator on Mars is challenging what scientists previously knew about when and where water flowed on Mars.

Earth's temporary asteroid friend last year was a chunk of its real moon that had been blasted into space thousands of years ago, scientists find.
