The jet observed by the Atacama Large Millimeter/submillimeter Array (ALMA) is ejecting material away from MWC 349A at a blistering 500 km per second (311 miles per second) and is likely launched by a magnetohydrodynamic wind — a type of wind whose movement is dictated by the interplay between the star’s magnetic field and gases present in its surrounding disk. This artist’s conception shows a zoomed in view of MWC 349A and its surrounding...
