Space Tornado -- Physicists Spot Interstellar Shock Wave Using Spitzer Telescope

"The spirals of a 'space tornado' may be the first step in the formation of a new star. The structure, observed with NASA's Spitzer infrared telescope, is a shock wave created by a jet of material slamming on a cloud of interstellar gas and dust at more than 100 miles per second, heating the cloud and causing it to glow. Physicists say the jet may have been generated by magnetic fields."
