Solar plumes are long, feathery jets that extend from near the poles of the Sun to more than 13 million miles into space. They may be the origin of high-speed solar wind. Solar plumes expel a high-speed stream of plasma from the corona that can reach one million degrees! The base of the plume contains churning magnetic fields and solar gases. At its base, a plume is about 2500 km (1580 miles).
