"The aurora may become visible over much of the northern half of the country, and maybe as far south as Alabama to northern California," NOAA predicted.

Illinois, Oregon and more northerly states may see the aurora tomorrow as solar storms slam into our planet's magnetic field.

"These areas could be modified during a geomagnetic storm to prevent transformers burning out and to limit damage to the wider power grid," Lauren Orr said.

"Auroras and geomagnetically induced currents are caused by similar space weather drivers," researcher Denny Oliveira said.

"We proved that this unique aurora was produced by suprathermal electrons streaming directly from the Sun," the researchers wrote.

The weakened magnetic field may have led to increased oxygen concentrations in our atmosphere and oceans, triggering an explosion of animal evolution.

"More than 500,000 satellites are expected in decades ahead, primarily to build internet megaconstellations," physics graduate student Sierra Solter said.

The rippling of Mercury's magnetic field in the solar wind has been detected, revealing the secrets of the planet's magnetosphere to scientists.

"Our study suggests that fewer birds migrate during large geomagnetic storms," study author and University of Michigan ecologist Ben Winger told Newsweek.

A plume of solar protons spat out by the sun has accelerated towards the Earth, and were funneled down into the polar regions by our magnetic field.

The northern lights were spotted as far south as California due to a severe G4 geomagnetic storm pummeling Earth's atmosphere and magnetic field.

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.
