Astronomers track bubbles on a star’s surface in the most detailed video yet | ALMA Observatory

For the first time, astronomers have captured images of a star other than the Sun in enough detail to track the motion of bubbling gas on its surface. The images of the star, R Doradus, were obtained with the Atacama Large Millimeter/submillimeter Array (ALMA), in July and August 2023. They show giant, hot bubbles of...
