Scientists figure out how solar prominences form
Prominences are filaments of cool plasma extending from the surface of the Sun that can persist for weeks. Scientists have gained valuable insights into how the material in these prominences are replenished.
New Delhi: Huge structures of cool plasma appear within the corona, or outer atmosphere of the Sun, known as prominences. These can span several thousand kilometres, and resemble flickering flames. They can take on a variety of shapes, and despite their tenuous appearance, they are chunks of matter, with densities exceeding that of the surrounding corona by over a hundred times. Prominences can remain stable for weeks, and even months.........
