What is creating the strange texture of IC 418? Dubbed the Spirograph Nebula for its resemblance to drawings from a cyclical drawing tool, planetary nebula IC 418 shows patterns that are not well understood. Perhaps they are related to chaotic winds from the variable central star, which changes brightness unpredictably in just a few hours. By contrast, evidence indicates that only a few million years ago, IC 418 was probably a well-understood star similar to our Sun. Only a few thousand years ago, IC 418 was probably a common red giant star. Since running out of nuclear fuel, though, the outer envelope has begun expanding outward leaving a hot remnant core destined to become a white-dwarf star, visible in the image center. The light from the central core excites surrounding atoms in the nebula causing them to glow. IC 418 lies about 2000 light-years away and spans 0.3 light-years across. This recently released false-color image taken from the Hubble Space Telescope reveals the unusual details.

"SUIT SUIT"
Today is Yellow Pig Day -it is a mathematician's holiday celebrating yellow pigs (is there such a thing!?!), and the number 17. It is celebrated annually since the early 1960's, primarily on college campuses, and primarily by mathematicians. On campus, Yellow Pig Cake and Yellow Pig Carols are tradition! It's also Wrong Way Corrigan Day. Douglas “Wrong Way” Corrigan was an American aviator who, in 1938, after a transcontinental flight from Long Beach, California, to New York, he flew from Floyd Bennett Field in Brooklyn, New York, to Ireland, even though he was supposed to be returning to Long Beach. He claimed that his unauthorized flight was due to a navigational error, caused by heavy cloud cover that obscured landmarks and low-light conditions, causing him to misread his compass.
