          Solar spicule

          Jet of plasma in the Sun's chromosphere

          In solar physics, a spicule, also known as a fibril or mottle,[a] is a dynamic jet of plasma in the Sun's chromosphere about 300 km in diameter.[1] They move upwards with speeds between 15 and 110 km/s from the photosphere and last a few minutes each[1] before falling back to the solar atmosphere.[2] They were discovered in 1877 by Angelo Secchi, but the physical mechanism that generates them is still hotly debated.

          Description

          Spicules last for about 15 minutes;[3] at the solar limb they appear elongated (if seen on the disk, they are known as "mottles" or "fibrils"). They are usually associated with regions of high magnetic flux; their mass flux is about 100 times that of the solar wind.

          They rise at a rate of 20 km/s (or 72,000 km/h) and can reach several thousand kilometers in height before collapsing and fading away.
