Spicules: jets on the Sun

Spicules are "spikes of superheated gas" made up of plasma that are on the sun. they are 300 miles wide, and usually about 3,000 miles long. They move at a speed of 50,000 miles per hour and then vanish after about 5 minutes. this characteristic of spicules makes them very hard to study in depth.Spicules are one of many factors that generate an intense solar wind on the surface of the Sun. It is believed that the periodic regeneration of a spicule about every five minutes is caused by sound waves of a ring, much like that of a bell, being emitted  from the inside of the Sun. These sound waves form shock waves, which  make a spicule shoot out. Spicules may also contribute to the extrememly high temperature of the corona of the Sun, which is 1.8 milion degrees farenheight, much higher in temperature than the surface of the Sun. There is still  much to learn about the mysterious spicules that engulf the Sun.
