Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2022 March 2 [2]The featured image shows the Sun undergoing a large eruption in mid-Feburary where a large prominence is visible. Please see the explanation for more detailed information. Record Prominence Imaged by Solar Orbiter Image Credit: [3]Solar Orbiter, [4]EUI Team, [5]ESA & [6]NASA; [7]h/t: [8]Bum-Suk Yeom Explanation: What's happened to our Sun? Last month, it produced the largest [9]prominence ever imaged together with a [10]complete solar disk. The record image, [11]featured, was [12]captured in [13]ultraviolet light by the Sun-orbiting [14]Solar [15]Orbiter [16]spacecraft. A quiescent [17]solar prominence is a cloud of hot gas held above the [18]Sun's surface by the [19]Sun's magnetic field. This [20]solar prominence was huge -- spanning a length rivaling the diameter of the Sun itself. Solar prominences may [21]erupt unpredictably and [22]expel hot gas into the Solar System via a [23]Coronal Mass Ejection (CME). When a [24]CME strikes the Earth and its [25]magnetosphere, bright [26]auroras may occur. This prominence did produce a [27]CME, but it was directed well away from the Earth. Although surely related to the Sun's changing magnetic field, the energy mechanism that creates and sustains a [28]solar prominence remains a [29]topic of research.
