What is a solar prominence?

Answer 1

Solar ProminencesHigh energy occurrences on or near the surface of the sun that are associated with its changing magnetic field. Typically, they are explosions caused by the very rapid release of energy stored in the magnetic field (although the exact mechanism is not known). These prominences usually appear as loops moving along, but not across, magnetic field lines that are anchored at both ends to the sun. Solar flares and sunspots are good examples of solar prominences.

Simple Answer: huge reddish loops of gas that often link different parts of sunspot regions.

Answer 2

A solar prominence is a large and very bright feature extending outward from the Sun's surface, often in the shape of a loop.

Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's corona.

Answer 3

A solar prominence is a large and bright gaseous feature that extends outward from the sun's surface into its outer atmosphere, known as the corona. These structures are often shaped like loops or arches, and are formed by the sun's magnetic field interacting with its plasma. Solar prominences are visible during total solar eclipses or with specialized solar telescopes.
