Glossary term: 코로나질량방출(CME)
Description: 코로나질량방출(CME)은 태양이나 다른 별에서 플라즈마와 자기장이 한꺼번에 우주 공간으로 폭발하듯 방출되는 현상입니다. CME는 자기장의 폭발로 인해 일어나며, 보통 태양 플레어(태양의 밝기가 갑자기 강해지는 현상)와 함께 나타납니다. 하지만 플레어가 빛과 에너지의 방출이라면, CME는 실제 물질이 우주로 튀어나가는 현상이라는 점이 다릅니다. CME의 모양, 밀도, 속도는 매우 다양합니다. 만약 CME가 지구 방향으로 향한다면, 지구의 자기장과 부딪혀 강한 지자기 폭풍을 일으킬 수 있습니다.

A Coronal Mass Ejection
Caption: A burst of solar material can be seen erupting from the Sun in this view, illustrating a coronal mass ejection (CME)—a large eruption of plasma and magnetic field from the Sun’s outer atmosphere, or corona. These CMEs are caused by magnetic explosions in the Sun's corona. During a CME, huge amounts of electrically charged particles are launched into space at great speeds, carrying part of the Sun’s magnetic field with them. These events are driven by changes in the Sun’s magnetic structure and release vast clouds of hot gas that travel outward into the solar system. When a CME moves through space, it can interact with a planet’s magnetic field and atmosphere, sometimes creating spectacular auroras or, in strong cases, interfering with artificial satellites and power systems.
CMEs are often associated with a temporary brightening of the region of the Sun where the CME originated. This is known as a solar flare. Stars other than the Sun can also have CMEs and flares.
This image was taken by NASA's Solar Dynamics Observatory (SDO). This is a space mission to monitor the Sun. The image here is taken at a special wavelength which partially ionised helium emits strongly at.
