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
