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 w ritten by a professional astronomer. 2021 November 8 IFRAME: [2]https://www.youtube.com/embed/7NykS2kv_k8?playlist=7NykS2kv_k8&loop= 1;rel=0&autoplay=1 A Filament Leaps from the Sun Video Credit & Copyright: [3]Stéphane Poirier Explanation: Why, sometimes, does part of the Sun's atmosphere leap into space? The reason lies in changing [4]magnetic fields that thread through the [5]Sun's surface. Regions of strong surface magnetism, known as [6]active regions, are usually marked by dark [7]sunspots. Active regions can channel charged gas along arching or sweeping magnetic fields -- gas that sometimes [8]falls back, [9]sometimes escapes, and sometimes not only escapes but [10]impacts our Earth. The [11]featured one-hour time-lapse video -- taken with a [12]small telescope in [13]France -- captured an eruptive filament that appeared to leap off the Sun late last month. The filament is huge: for comparison, the size of the Earth is shown on the upper left. Just after the [14]filament lifted off, the [15]Sun emitted a powerful X-class flare while the surface rumbled with a tremendous [16]solar tsunami. A result was a cloud of charged particles that rushed into [17]our Solar System but mostly [18]missed our Earth -- this time. However, enough solar plasma did impact our [19]Earth's magnetosphere to create a few [20]faint auroras.
