Exposure to cosmic radiation and weightlessness in space could increase the risk of astronauts developing erectile dysfunction, according to research in rats.

A massive sunspot region made up of at least six different sunspot groups has emerged on the sun's nearside. The "archipelago" of dark patches is spitting out solar storms at an alarming rate and Earth will soon be in the firing line.

The massive volcanic comet 12P/Pons-Brooks, which grows giant horns when it erupts, has exploded for a third time in five months as it continues to race toward the sun.

A powerful explosion from the sun briefly opened up an enormous valley on the solar surface that was more than twice as wide as the contiguous U.S. and seven times longer than Earth.

Mystery blobs in Earth's mantle may be chunks of a Mars-sized space rock that crashed into our planet 4.5 billion years ago, scientists discover.

NOAA's Space Weather Prediction Center has released a "revised prediction" for the current solar cycle, which states that the upcoming solar maximum will arrive sooner and be more explosive than they initially forecast — as Live Science previously reported.

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.
