Astronomers have captured the first detailed images of gas bubbles on the surface of the red giant star R Doradus, using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. These hot gas bubbles, each 75 times the size of the Sun, rise and fall through convection, similar to a lava lamp, and move faster than expected. R Doradus, 350 times the diameter of the Sun and 180 light-years away, provides a glimpse into the future of our own Sun, which will become a red giant in about 5 billion years. The high-resolution images allowed researchers to track the movement of these bubbles, which distribute heavy elements like carbon and nitrogen throughout the star and contribute to stellar winds that spread these elements to form new celestial bodies. These findings, published in Nature, offer unprecedented insights into the dynamics of aging stars.
