1 day agoThe sun just unleashed its most powerful solar flare in years
The sun is putting on a show. On Sunday the star unleashed several strong and bright solar flares, including one of the most powerful eruptions seen in decades.

When these fields snap, they can throw out huge bursts of energy and charged particles into spacea solar flare.
