Massapurkaus, often translated as mass ejection or mass discharge, refers to the expulsion of a significant amount of matter from a celestial body. In astrophysics, the term is commonly used to describe phenomena occurring on stars, particularly our Sun. Solar mass ejections are a type of solar activity that can involve the expulsion of plasma and magnetic field from the Sun's corona. These events can take various forms, including coronal mass ejections (CMEs) and solar flares.

CMEs are vast clouds of solar wind and magnetic fields released into space. They can travel at high speeds and, if directed towards Earth, can cause geomagnetic storms. These storms can disrupt satellite operations, power grids, and radio communications. Solar flares, on the other hand, are sudden bursts of electromagnetic radiation from the Sun's surface, often accompanied by the release of charged particles. While flares are primarily radiation events, they can sometimes be associated with mass ejections.

The study of mass ejections is crucial for understanding solar physics and space weather. Scientists monitor solar activity using various instruments to predict and mitigate the potential impacts of these energetic events on Earth and technology. The mechanisms driving mass ejections are complex, involving the buildup and sudden release of magnetic energy in the Sun's atmosphere.
