In 1054, humans recorded sightings of the mega-star explosion that created the Crab Nebula. It was so bright it was visible to the naked eye. Now three space telescopes have together created a more complete picture of the debris.
According to National Geographic:
This new picture of the Crab Nebula combines data from the Chandra X-ray Observatory, the Hubble Space Telescope, and the Spitzer Space Telescope . . . Infrared light caught by Spitzer and visible light seen by Hubble paint the nebula's expanding debris cloud in shades of purple and red. Meanwhile, Chandra's x-ray vision is helping astronomers understand the high-energy particles (seen in blue) coming from the dead star's core, known as a [sic] white dwarf.
