Betelgeuse,ALMA image
Betelgeuse,ALMA image. Betelgeuse,a red supergiant,is one of the largest stars currently known,with a radius around 1400 times larger than the Sun's. Here,it is seen by the Atacama Large Millimeter/submillimeter Array (ALMA). This is the first time that ALMA has ever observed the surface of a star and this first attempt has resulted in the highest-resolution image of Betelgeuse available. This supergiant star is about eight million years old and on the verge of becoming a supernova. It has a giant plume of gas almost as large as the solar system,and a massive bubble boiling on its surface. These structures were detected using the ESO's Very Large Telescope (VLT). This discovery helps to explain how supergiant stars shed material at a tremendous rate. Betelguese is located around 600 light years from Earth,in the constellation of Orion.
