A massive column of sulfur dioxide pumped out by the erupting volcano on Iceland's Reykjanes Peninsula is traveling across northern Europe. Scientists are concerned it could impact the ozone layer.

A large swirl of white light that temporarily outshone vibrant auroras in the Arctic last week was triggered by the death throes of a SpaceX rocket that deployed more than 50 satellites into space.

A gigantic plasma eruption from the sun's hidden far side recently launched a sizable coronal mass ejection that slammed into Mercury, potentially triggering invisible X-ray auroras around the planet's rocky surface.

The proposed nuclear reactor, which could be transported and assembled without human assistance, would provide energy to a lunar base that Russia and China have agreed to build together.

Comet 12P/Pons-Brooks is currently sailing past the Andromeda Galaxy in the night sky as it races toward Earth, and you can watch it live today.

A NASA satellite recently spotted a series of bizarre "fallstreak holes" in clouds above Florida. The circular cloud gaps have been previously (and incorrectly) linked to paranormal phenomena.

Researchers found and mapped four seamounts in the deep sea off the coast of Peru and Chile. The tallest of these new peaks rises around 1.5 miles above the seafloor.

A recent solar flare unleashed a massive plasma plume from the sun's south pole, where these stellar eruptions rarely happen. The unusual phenomenon is a sign of the impending solar maximum.

A photographer recently snapped an incredibly detailed photo of gigantic, ghostly plasma loops towering above the sun's fiery surface after a powerful solar flare exploded from the sun.

A "potentially hazardous" space rock the size of a football stadium is about to reach its closest point to our planet for more than 100 years, and it won't get this close to us again for centuries more.

A brief flash of green light was recently spotted coming from Venus in the night sky. The colorful shimmer has only been seen a handful of times before.

A pair of linked solar flares recently exploded near-simultaneously from sunspots on different hemispheres of our home star, triggering radio blackouts on Earth.

The inexplicable entity, which likely had a chemical composition unlike any other known star, was identified by a group of "stellar archaeologists" who traced back the cosmic history of another equally unique star.

We worked out how many trips each of the solar system's eight planets has taken around the sun over the past 4.6 billion years.

While hunting for dark matter, astronomers accidentally discovered the first known stellar stream stretching between galaxies. The trail of stars is also the longest ever seen.

After the warmest autumn ever, researchers are confident 2023 will be the hottest year on record before it has even finished.

An eerily-perfect ring of light was spotted around the full moon in Florida during the recent launch of a SpaceX Falcon 9 rocket, creating a stunning new photo.

A monstrous dark patch, known as a coronal hole, recently appeared near the sun's equator. The temporary gap enables unusually fast solar wind to race toward Earth.

NASA has revealed a new false-color image of Alaska's Malaspina Glacier that highlights several recent findings about the massive ice mass.

Experts are concerned that these blood-red light shows could be causing unknown problems for astronomy and communication.

A new series of experiments has shown that the mysterious "E-prime layer," which surrounds Earth's outer core, is created by water that leaks deep into our planet's interior.

The "archipelago" of dark patches is rapidly unleashing solar storms, and Earth may soon be in the firing line.

The latest eruption of the cryovolcanic comet 12P/Pons-Brooks, which will make its closest approach to Earth next year, shows that the icy object may have lost its iconic devil horns for good.

Russia's Klyuchevskoy volcano, which is the tallest volcano in Europe and Asia, violently erupted on Nov. 1 and left behind a trail of smoke and ash that was photographed by NASA satellites.

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.
