Solar Prominence by Hinode Solar prominence is cool gas floating in the solar atmosphere. Prominence material is denser than surrounding coronal plasma, but it is sometimes suspended in the corona for a long time. Coronal magnetic fields could act like a hammock, supporting the prominence material. Gas in the prominence moves up and down, showing the waves are propagating along magnetic field lines. It is thought that this wave may carry energy from the photosphere to the corona and that the ene

A large eruption occurs off the limb of the Sun in this image sequence, and you can see the solar prominence in the lower right. ☀️ Prominences appear when relatively cooler gas from lower layers of the Sun’s atmosphere is trapped in a magnetic field loop that extends outward from the Sun’s surface, into the hotter corona.
