A massive solar filament erupted today (May 7), producing a stunning display that spanned the sun's eastern limb and reached deep into the solar disk.
Filaments are cooler, dense ribbons of solar plasma that can hang suspended above the sun's surface by magnetic fields, according to NOAA. When these become unstable, they can erupt dramatically, sometimes launching coronal mass ejections (CMEs) into space — powerful blasts of solar plasma and magnetic fields that can trigger geomagnetic storms here on Earth. However, in today's eruption, the filament was oriented away from Earth, meaning it will have no direct impact on our planet.
