Strange rings of light were spotted around the sun in Finland, as a result of pollen in the air diffracting the sunlight.

Solar tornadoes can have wind speeds of up to around 310,000 miles per hour, as opposed to the 300 mph top speed of tornadoes on Earth.

The sun spat out a rare X1.9 flare on January 9 from one of three large and unstable sunspots.

Five large sunspots have appeared on the Sun's surface, and are facing towards the Earth, putting us in the line of fire for solar flares and CMEs.

Both events show the star releasing huge amounts of energy.

Sunspot AR3078 already launched a moderate-strength solar flare toward Earth on Tuesday morning, with the potential for more to come.

Cosmic rays recorded in the atmosphere above California have dropped sharply thanks to the sun's increasing activity.

A huge "full-halo" solar ejection is headed straight for Earth, and will result in spectacular auroral displays on July 23.

The minor storm will be caused by a high-speed stream of particles launched from the sun through a "hole" in its atmosphere.

Another solar eruption could also be about to sideswipe our planet today.

Be prepared for fire season, blackouts or other emergencies with an electric generator that's powerful enough to run your most needed devices.

Imagine just how much money you can save by generating your own electricity through solar power.

The annular solar eclipse will pass over parts of Africa, Asia and Australia, but stargazers across the world can watch the event via livestream.

The jets were recorded coming from sunspots—temporary regions on the Sun with reduced surface temperatures.

What really lies at the heart of this complicated and popular topic is evidence.

The strength of our planet's magnetic field was 10 times lower than it is today.

Earth reached perihelion, the point at which the sun is closest to Earth, at 2:19 a.m. ET on January 3.

The prominence was about 10 times the diameter of Earth.

Report reveals how bees responded to the eclipse—with just one single buzz during the darkest moments.

The Parker Solar Probe will zoom toward the sun at speeds of up to 430,000 miles per hour, making it the fastest spacecraft ever flown.

Solar winds can impact power grids, GPS and even animal migration.

Here's how to see it.

The event in the Earth's upper atmosphere had been theorized before, but never detected.

The sun will balloon, bubble and burst.

While scientists had suspected plasma sheets were unstable, no one had ever managed to characterize that instability until now.

"It's like the eclipse shape was burned into her retina," a doctor said about one patient.

Saturn's Enceladus has become a prime search location for alien life as potentially habitable waters appear to flow beneath its icy crust.

It's only been seen a handful of times.

The solar panels use tiny organisms to photosynthesize sunlight, converting it into energy.
