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 spectacular red lights in the sky were caused by a G3 geomagnetic storm interacting with Earth's atmosphere.

The AR3182 sunspot has developed an unstable "beta-gamma-delta" field, making it more prone to spewing out violent X-class solar flares.

An enormous gamma-ray burst from a dying star was the most powerful recorded, scientists have said.

Earthquakes are caused by tectonic plates suddenly slipping at fault lines, releasing large amounts of energy as seismic waves.

The explosion far surpassed the Earth in size. "I tracked it nearly a million miles out into space," astrophotographer Andrew McCarthy wrote on Reddit.

The phenomenon could mean that more auroras are visible across the northern hemisphere as the fall equinox approaches this month.

Sunspot AR3089, which is pointed at the Earth, may be about to eject a powerful X-class solar flare.

A hybrid electromagnet in China produced the strongest steady magnetic field ever recorded at 45.22 Tesla.

"Seeing a brilliant aurora is a life changing experience," climatologist Brian Brettschneider, who posted the footage, told Newsweek.

The research showed that the planet's inner core is likely both liquid and solid at the same time.

"We are discovering that our standard models of the sun are missing some very fundamental physics," Parker Solar Probe scientist Justin Kasper told Newsweek.

Scientists will use FAST to look for magnetic fields on exoplanets—a sign life could exist there.

The kauri tree, found in New Zealand, lived over 40,000 years ago.

Magnetic reconnection is a sudden release of magnetic energy.

A magnetic field reversal is not the sort of thing we necessarily want to live through firsthand, though the phenomenon remains a mystery.

As the tides ebb and flow, so does an elusive magnetic signal.

NASA has begun to decode its mysterious radio signals.

After hundreds of thousands of years, signs of this change are finally apparent.

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

Earth's magnetic field has reversed periodically throughout the planet's history. Now, we're a little closer to understanding why.
