Solar Coronal Rain from IRIS (Interface Region Imaging Spectrograph) Feb. 28/2018 This movie, taken on 6-Mar-2015 at the solar limb, shows "coronal rain": plasma that is rapidly cooled from millions of degrees to only about 30,000 K and subsequently slides back to the solar surface along magnetic field lines. Coronal rain plasma reaches very high speeds (10-100 km/s) on its way down and is used to diagnose conditions and heating mechanisms in the coronal volume. Towards the end of this movie a v

IRIS • Solar Coronal Rain and Flare over AR 11996 - Coronal Rain Slit Parallel to Limb 17.4.2021 • Coronal rain seen here by the IRIS over a period of approximately 2 hours on 14.O3.2014. Coronal rain is a phenomenon that occurs in the sun's corona. It occurs when hot plasma in the corona cools and condenses in strong magnetic fields, usually associated with regions that produce solar flares. The plasma is attracted to the magnetic fields where it condenses and slowly falls back to the solar sur

• Coronal Rain • forms when hotter plasma in the Sun’s corona cools down and becomes denser. Like raindrops on Earth, coronal rain is pulled down to the surface by gravity. Because the plasma is electrically charged, it follows the magnetic field lines, which make huge arches/loops, instead of falling in a straight line. This image is a snapshot from a 23-minute time-lapse video which is comprised of the highest resolution images ever made of coronal rain. The scientists show in the paper that t
