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.

Researchers are developing a real-life tractor beam, with the goal of pulling defunct satellites out of geostationary orbit to alleviate the space junk problem.

A striking new image shows bright orange auroras dancing in the night sky above Canada. But auroras should never be this color, so what's going on?

NASA has released a new image of an eerie, cranium-shaped caldera in the Sahara Desert, which looks like it is staring right at the orbiting camera.

Scientists have created the world's first nanophotonic electron accelerator, which speeds negatively charged particles with mini laser pulses and is small enough to fit on a coin.

Aurora records in royal chronicles from Korea show that during the 'Maunder Minimum' between 1645 and 1715, the sun's solar cycles became several years shorter than they are today.

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.

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.

Hefty iceberg D-30A has collided with Clarence Island — an important refuge for breeding penguins in Antarctica. But luckily, the penguins weren't at home when the berg struck.
