[1] Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2019 May 26 A Solar Prominence Eruption from SDO Image Credit & Copyright: NASA [2] / Goddard [3] / SDO AIA Team [4] Explanation: One of the most spectacular solar sights is an erupting prominence. In 2011, NASA's Sun-orbiting Solar Dynamic Observatory [5] spacecraft imaged an impressively large prominence [6] erupting from the surface. The dramatic explosion [7] was captured in ultraviolet light in the featured time lapse video [8] covering 90 minutes, where a new frame [9] was taken every 24 seconds. The scale of the prominence is huge -- the entire Earth [10] would easily fit under the flowing curtain [11] of hot gas. A solar prominence [12] is channeled and sometimes held above the Sun's surface by the Sun's magnetic field [13] . A quiescent prominence typically lasts about a month, and may erupt in a Coronal Mass Ejection [14] (CME) expelling hot gas [15] into the Solar System [16] . The energy mechanism that creates a solar prominence [17] is still a topic of research [18] . After our Sun passes the current Solar Minimum [19] , solar activity [20] like eruptive prominences [21] are expected to become more common over the next few years.
