About this episode
Listener Graham wanted to know what solar flares are and what causes them, so we reached out to NASA Heliophysicist Nicola Fox to help us figure out why these bright flashes on the sun’s surface occur. Got a question that’s been flaring up in your mind? Send it to us at BrainsOn.org/contact , and we’ll help make you brighter ! See omnystudio.com/listener for privacy information.
