Because the plasma is charged, it's strongly influenced by the sun's magnetic field. As it rained down, it condensed along twisted magnetic field lines close to the surface and formed giant streaming arcs, some as tall as five Earths stacked high. An ultra high-definition telescope aboard NASA's Solar Dynamics Observatory (SDO) captured images of the display, which lasted hours and was initiated by two eruptive events on the sun: a solar flare and coronal mass ejection. Scientists used a 304-angstrom-wavelength filter to see the plasma downpour. Watch the video to see it for yourself. || ", "release_date": "2013-03-28T00:00:00-04:00", "update_date": "2023-05-03T13:52:17.060149-04:00", "main_image": { "id": 466939, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a011100/a011198/cover-1920.jpg", "filename": "cover-1920.jpg", "media_type": "Image", "alt_text": "A NASA spacecraft records a plasma downpour in ultra HD.", "width": 1920, "height": 1080, "pixels": 2073600 } }, { "id": 4026, "url": "https://svs.gsfc.nasa.gov/4026/", "page_type": "Visualization", "title": "July 2012: Coronal Rain", "description": "A moderate solar flare was emitted by the sun on July 19, 2012. At 5:58 UTC it peaked at M7.7 on the flare scale, which makes it fairly powerful, but still much weaker than X-class flares, which are the largest. What made this particular event so noteworthy was the associated activity in the sun's corona. For the next day, hot plasma in corona cooled and condensed along the strong magnetic fields of the region that produced the flare. Magnetic fields are invisible, but the plasma is very obvious in the extreme ultraviolet wavelength of 304 angstroms, which highlights material at a temperature of about 50,000 Kelvin. This plasma is attracted to the magnetic fields and outlines them very clearly as it slowly falls back to the solar surface. This process of condensing plasma falling to the surface is called coronal rain.The footage in this video was collected by the Solar Dynamics Observatory's AIA instrument. SDO collected one frame every 12 seconds so each second in this video corresponds to 6 minutes of real time. The video covers 4:30 UTC on July 19th to 2:00 UTC on July 20th, a period of 21 hours and 30 minutes.Music—\"Thunderbolt\" by Lars Leonhard || ", "release_date": "2013-02-20T10:00:00-05:00", "update_date": "2025-02-02T22:09:50.215978-05:00", "main_image": { "id": 469747, "url": "https://svs.gsfc.nasa.gov/vis/a000000/a004000/a004026/AIA304July2012rain_stand.HD1080i.03000.jpg", "filename": "AIA304July2012rain_stand.HD1080i.03000.jpg", "media_type": "Image", "alt_text": "An HD1080 movie of the coronal rain (right limb of sun) in the 304 Å wavelength.", "width": 1920, "height": 1080, "pixels": 2073600 } }, { "id": 11047, "url": "https://svs.gsfc.nasa.gov/11047/", "page_type": "Produced Video", "title": "AR1520's Parting Shot: July 19, 2012 M7.7 Flare", "description": "The sun emitted a moderate solar flare on July 19, 2012, beginning at 1:13 AM EDT and peaking at 1:58 AM. Solar flares are gigantic bursts of radiation that cannot pass through Earth's atmosphere to harm humans on the ground, however, when strong enough, they can disrupt the atmosphere and degrade GPS and communications signals.The flare is classified as an M7.7 flare. This means it is weaker than the largest flares, which are classified as X-class. M-class flares can cause brief radio communications blackouts at the poles.Increased numbers of flares are currently quite common, since the sun's standard 11-year activity cycle is ramping up toward solar maximum, which is expected in 2013. It is quite normal for there to be many flares a day during the sun's peak activity. || ", "release_date": "2012-07-19T10:00:00-04:00", "update_date": "2023-05-03T13:52:55.290673-04:00", "main_image": { "id": 474021, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a011000/a011047/July_19_Flare_triptych-half_size.jpg", "filename": "July_19_Flare_triptych-half_size.jpg", "media_type": "Image", "alt_text": "Video showing the flare in 304 and 335 angstrom light.
