Solar plumes

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).
