A composite image shows the Crab Nebula, the remains of an exploded star in the constellation Taurus. The star exploded in 1054 as seen from Earth, and was recorded by several cultures. The nebula, also known as Messier 1, is expanding at more than two million miles per hour (3 million kph). This image combines an optical view from Hubble Space Telescope (blue) with an infrared view from Herschel Space Telescope (red). [ESA/NASA/et. al]
