Detailed explanation-1: -A solar prominence (also known as a filament when viewed against the solar disk) is a large, bright feature extending outward from the Sun’s surface. Prominences are anchored to the Sun’s surface in the photosphere, and extend outwards into the Sun’s hot outer atmosphere, called the corona.
Detailed explanation-2: -A solar prominence (also known as a filament) is an arc of gas that erupts from the surface of the Sun. Prominences can loop hundreds of thousands of miles into space. Prominences are held above the Sun’s surface by strong magnetic fields and can last for many months.
Detailed explanation-3: -A prominence is anchored to the sun; the arch does not separate and go into space. A solar flare, though, will travel through space, since it is a release of energy. A solar prominence can break down and release a solar flare, but that does not always happen.
Detailed explanation-4: -solar prominence, dense cloud of incandescent ionized gas projecting from the Sun’s chromosphere into the corona. Prominences sometimes extend hundreds of thousands of kilometres above the Sun’s chromosphere. Their causes are uncertain but probably involve magnetic forces.
Detailed explanation-5: -Solar flares are a sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots. The surface of the Sun is a very busy place. It has electrically charged gases that generate areas of powerful magnetic forces. These areas are called magnetic fields.
