A Prominence Bubble • This high resolution movie of a solar prominence highlights a phenomena called prominence bubbles. In regions where the Sun's magnetic field reverses sign, puffs of chromospheric material can be suspended above the Sun's surface. Sometimes, strong magnetic fields containing hot gas can occur under these puffs, forming what looks like a dome-shaped void. This void, called a magnetic bubble, can push up into the prominence material forming a bright ridge as seen in this movie
