Astronomers capture best picture yet of the star in Orion’s armpit http://ift.tt/2sb7IOA Betelgeuse isn't just an etymological inspiration for Michael Keaton's best role, it's a colossal star forming the right shoulder in the well-known constellation Orion. Astronomers used the Atacama Large Millimeter Array (ALMA) in Northern Chile to photograph it, producing the most detailed image yet of any star besides our own sun. While scientists knew that Betelgeuse's surface wasn't uniform, this high-resolution photo reveals that its inner temperature isn't, either. These temperature fluctuations on the star's surface resemble those happening on our sun's, a similarity more stunning due to the differences between the solar bodies: Betelgeuse is 1400 times larger, meaning if it sat at the center of our solar system, its edges would almost reach Jupiter.
