The atmospheric temperature spike, which was caused by successive geomagnetic storms, suggests the "solar maximum" is fast approaching.
NASA's Aqua satellite spotted giant ice swirls stretching for hundreds of miles in the Sea of Okhotsk off Russia's P'yagina Peninsula.
The extremely rare kaleidoscopic circles have a surprising Earth-based origin.
At least three separate optical phenomena are visible in the new images. Each of which is created by light refracting through millions of perfectly aligned ice crystals in the upper atmosphere.
An unusual green meteor recently exploded as it plummeted through the sky over Australia, giving off a brilliant flash of light that could be seen for miles.
A stunning composite image of the sun during a recent 'hybrid eclipse' in Australia is further proof that solar activity is ramping up.
Shortly after Mercury reached its closest point to the sun, its massive, comet-like tail became unusually visible in the night sky and was captured in a stunning new photo.
A mystifying swirl of light recently appeared in the night sky above Alaska, briefly outshining a vibrant auroral display.
A massive wall of falling plasma, known as a polar crown prominence, was recently captured in a stunningly-detailed new photo of the sun.
An enormous halo of red light flashed in the night sky above Italy before disappearing within milliseconds. It was likely caused by an electromagnetic pulse from a nearby thunderstorm.
A river of hazy red light stretched across the night sky over Denmark after the most powerful solar storm to hit Earth for six years slammed into our planet. The rare phenomenon is not an aurora.
Antarctica's sea ice recently shrank to its lowest extent since satellite records began more than 40 years ago.
The STEVE phenomenon was spotted across the U.S. and in parts of the U.K. after the most powerful solar storm to hit Earth for six years smashed into our planet.
Cyclone Freddy, which is finally dissipating after battering Southeast Africa, has crossed the entire Indian Ocean and made landfall three separate times.
The sun recently spat out an X-class solar flare, one of the most powerful it can emit, which triggered a rare shockwave across the sun's surface and caused radio blackouts on Earth.
The mysterious Planet Nine may have up to 20 moons that could be superheated by the hypothetical planet's gravitational pull, making them easy to spot.
Researchers have detected fluctuations in Earth's magnetosphere created by the same tidal forces that the moon exerts on the oceans.
Rare clouds that give off bright, multi-colored light like an aurora were recently spotted at multiple locations in the Arctic. But what causes them?
The only known filmed interview with physicist and Catholic priest Georges Lemaître, who originally proposed the Big Bang theory, has been found on a video that was lost nearly 60 years ago.
C/2022 E3 (ZTF), a comet that has recently made headlines as it flies closer to Earth, briefly developed an ethereal third tail thanks to a weird optical illusion.
A new time-lapse image shows two major sunspot groups moving across the surface of the sun in December 2022, when the number of solar splotches also skyrocketed to an eight-year high.
An astrophotographer has captured a highly detailed image of the Red Planet reappearing from behind the moon after a lunar occultation.
Astronomers observed a major eruption from a volcanic comet flying through the solar system, likely spewing more than 1 million tons of debris into space.
