Star-spots on Betelgeuse

Betelgeuse, in the constellation Orion, is one of the brightest stars in the night sky and is the second-largest star in apparent size from our vantage point (not counting the sun, that is). Those attributes are made all the more impressive by the fact that Betelgeuse is some 650 light-years away—nowhere near cracking the list of the closest stars to our solar system.

Astronomers have been able to observe the disk of Betelgeuse for many years but now they are really getting close up and personal.  What  an amazing achievement!
