No, Earth Wasn’t Nearly Destroyed by a 2012 Solar Storm

Credit: NASA/SDO/AIA

Yes, a large glob of plasma and magnetic fields from the sun did just miss us two years ago, as news organizations have feverishly reported over the past few days, following a NASA press release. At the time, scientists were hugely relieved it flew by Earth and missed us entirely. If it had hit, the [...]

Earth-Facing Sunspots Could Erupt This Weekend

Sunspot region 1476

Space weather forecasters are keeping a close watch on a large collection of sunspots that could unleash blasts of energy or charged particles toward Earth in the coming days. Sunspot region 1476, the dark patch resembling the Hawaiian Islands in the photo at left, is located near the center of the sun’s face as seen [...]

When It Comes to Solar Storms, We Don’t Even Know How Bad It Might Get

CME, solar storm, space weather, electricity

Space weather is not all bad. After all, the charged particles streaming out from the sun that cause geomagnetic disturbances on and around our planet also produce the lovely aurorae near Earth’s poles—and sometimes at much lower latitudes. But when the sun really acts up, spewing out heaps of charged particles in a burst called [...]

Largest Solar Storm Since 2005 to Hit Earth Tuesday

Last night the sun unleashed a flash of radiation called a solar flare, along with a generous belch of ionized matter that is now racing toward Earth at thousands of kilometers a second. The solar storm front from the ionized blast, called a coronal mass ejection (CME), should arrive tomorrow morning, according to the National [...]

See the Stormy Sun That Produced Yesterday’s Geomagnetic Disturbance [Video]

A “strong to severe” geomagnetic storm hit Earth yesterday, NASA says, after the sun unleashed a burst of plasma from a turbulent region two days prior. The region, known as sunspot 1302, has sent forth a few blasts of energy called solar flares, including a flare and an accompanying belch of plasma called a coronal [...]
