Zipping through space at close to the speed of light, Solar Energetic Particles, or SEPs, are one of the main challenges for the future of human spaceflight.

Clouds of these tiny solar projectiles can make it to Earth—a 93 million mile journey—in under an hour.

They can fry sensitive spacecraft electronics and pose serious risks to human astronauts.

But their onset is extraordinarily hard to predict, in part because we still don't know exactly where on the Sun they come from.

A solar flare from AR 11944 emitted on January 7th, 2014 seen in several different wavelengths of light from NASA’s Solar Dynamics Observatory.

From right to left, the artificially-colored images show plasma at approximately 1 million degrees Fahrenheit (600,000 degrees Celsius), 4.5 million degrees Fahrenheit (2.5 million degrees Celsius), and 12.7 million degrees Fahrenheit (7.1 million degrees Celsius).

A close-up view of one of the flares from AR 11944 emitted on January 7th, 2014.

This flare may be how the SEPs detected by Wind were released from the Sun.

This imagery captured by NASA’s Solar Dynamics Observatory shows a solar flare and a subsequent eruption of solar material that occurred over the left limb of the Sun on November 29, 2020.

From its foot point over the limb, some of the light and energy was blocked from reaching Earth – a little like seeing light from a lightbulb with the bottom half covered up.
