ALMA Reveals Long-Lived Hotspots on Betelgeuse's Bubbling Surface
A remarkably detailed image obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) reveals the uneven surface of Betelgeuse, the famous red supergiant in the constellation Orion. The observations show bright hotspots and an irregular, corrugated outline shaped by the enormous motions taking place within the star. Located roughly 600 light-years from Earth, Betelgeuse is one...
Summary
New images from ALMA provide a stunning look at the surface of Betelgeuse, highlighting its bright hotspots and irregular features caused by intense stellar activity. This detailed observation sheds light on the dynamics of one of the most studied stars in our galaxy, located about 600 light-years away.
