How Does NASA | The Difference Between CMEs and Solar Flares Work?

NASA studies space weather from the Sun, and two big events are CMEs and Solar Flares.

Think of the Sun like a giant, fiery ball that’s always happy, but sometimes it gets super excited. When it gets excited, it sends out energy or plasma (which is like hot gas) into space, these are called Solar Flares and Coronal Mass Ejections, or CMEs for short.

A Solar Flare is like when the Sun sneezes. It sends out a quick burst of light and energy, but it doesn’t send much matter along with it. You can think of it like a flash of light, bright, but not heavy.

A CME is more like a big bubble of hot gas that the Sun throws into space. It's slower than a Solar Flare, but it carries more stuff, like a giant, floating balloon full of heat and particles.

Sometimes, both happen at once, a sneeze with a big bubble attached! That’s when things get really interesting in space weather. NASA studies space weather from the Sun, and two big events are CMEs and Solar Flares.
