The cryovolcanic comet 12P/Pons–Brooks, which will make its closest approach to Earth next year, has re-sprouted its distinctive "horns" after its second major eruption in four months.

The center of Earth lies around 4,000 miles beneath our feet — but what lies beneath the outer crust and the inner core?

Atoms within the enormous ball of iron in Earth's inner core may move around much more than previously thought, which could explain recent findings about the core's surprising softness.

The Perseverance rover has captured footage of an unusually large twister, or "dust devil," moving across the Martian landscape. Based on images of the swirling storm, researchers estimate that it could be more than a mile tall.

The comet Nishimura, which was only discovered in August, will soon be slingshotted around the sun and back out toward the edge of the solar system where it will remain for centuries.

Researchers have shown that if the James Webb Space Telescope was pointed at Earth from a distant star, it could detect the signatures of intelligent life in our planet's atmosphere.

Earth is the only rocky body in the inner solar system with strong magnetic poles. But where do these poles come from, and what do they do?

A patchwork of polygon-shaped cracks in ancient Martian mud are evidence of past wet-dry cycles, which could have helped extraterrestrial life emerge on the Red Planet.
