The surface of the sun churns with energy and frequently ejects masses of highly-magnetized plasma towards Earth. Sometimes these ejections are strong enough to crash through the magnetosphere the natural magnetic shield that protects the Earth damaging satellites or electrical grids. Such space weather events can be catastrophic.
Astronomers have studied the sun s activity for centuries with greater and greater understanding. Today, computers are central to the quest to understand the sun s behavior and its role in space weather events. ....

On Dec. 14, 2020, the Moon s shadow raced across Chile and Argentina, casting a thin ribbon of land into brief, mid-day darkness.
Those in the path of this total solar eclipse glimpsed the solar system in motion. During a solar eclipse, the Moon crosses between the Sun and Earth, covering the bright face of the Sun. Weather permitting, a total eclipse reveals the Sun s otherwise hidden, pearl-white halo of an atmosphere, called the corona. ....

Near Miss: The Solar Superstorm of July 2012
July 23, 2014: If an asteroid big enough to knock modern civilization back to the 18th century appeared out of deep space and buzzed the Earth-Moon system, the near-miss would be instant worldwide headline news.
Two years ago, Earth experienced a close shave just as perilous, but most newspapers didn t mention it. The impactor was an extreme solar storm, the most powerful in as much as 150+ years.
If it had hit, we would still be picking up the pieces, says Daniel Baker of the University of Colorado.
A ScienceCast video recounts the near-miss of a solar superstorm in July 2012. Play it ....
