An angry monster lurks in the shoulder of the Hunter. We’re talking about the Red Giant star Betelgeuse, Alpha Orionis in the constellation Orion. Recently, the Atacama Large Millimeter Array (ALMA) gave us an amazing view of Betelgeuse, one of the very few stars resolved as anything more than a point of light.

Images of the Crab Nebula are always a treat because of it has such intriguing and varied structure. Also, just knowing that this stellar explosion was witnessed and recorded by people on Earth more than 900 years ago (with the supernova visible to the naked eye for about two years) gives this nebula added fascination.
