2013年3月28日 · On July 19, 2012, million-degree plasma in the sun's atmosphere began to cool and fall to the surface, resulting in a dazzling magnetic display known as coronal rain. Because the plasma is charged, it's strongly influenced by the sun's magnetic field.

2013年2月20日 · A moderately powerful solar flare exploded on the sun's lower right hand limb, sending out light and radiation. Next came a CME, which shot off to the right out into space. And then, the sun treated viewers to one of its dazzling magnetic displays — a …

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.

Coronal rain is a phenomenon that occurs in the Sun's corona when hot plasma cools and condenses in strong magnetic fields and falls to the photosphere. It is usually associated with active regions, most obviously in the aftermath of a solar flare.

Scientists have long struggled to accurately predict solar flares, but a recent breakthrough using NASA ’s Solar Dynamics Observatory has uncovered a promising new sign: flickering coronal loops.

2019年4月5日 · Computer simulations predicted the coronal rain could be found there. Observations of the solar wind, the gas escaping from the Sun and out into space, hinted that the rain might be happening.

2024年8月11日 · In this study, employing data taken by the Solar Dynamics Observatory (SDO) and the Solar Upper Transition Region Imager (SUTRI) on 2022 October 11, we report three types of CR during an interchange reconnection between open and closed magnetic filed structures above the southeastern solar limb.

2016年8月5日 · We present the analysis of MHD oscillations and kinematics of the coronal rain observed in chromospheric and transition region lines by the Interface Region Imaging Spectrograph (IRIS), the Hinode Solar Optical Telescope (SOT), and the Solar Dynamics Observatory (SDO) Atmospheric Imaging Assembly (AIA). Two different regimes of transverse ...
