The Sun’s fiery hot sphere produces a variety of special features. Maybe the most intriguing is a so called solar prominence.
A solar prominence 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.

A prominence forms over timescales of about a day, and stable prominences may persist in the corona for several months, looping hundreds of thousands of miles into space.
That glowing looped material in the photo is plasma, a hot gas comprised of electrically charged hydrogen and helium. The prominence plasma flows along a tangled and twisted structure of magnetic fields generated by the sun’s internal dynamo.
Today's prominence maybe eventually associated with a very powerful surge of gas that flows outward “a coronal mass ejection“ that can light up Earth’s skies with an aurora and even interfere with our technology.
If you have a telescope fitted with an H-alpha filter, you can see these tongues of gas blasting above the Sun’s limb, and even watch them as they slowly change.
