SUMMARY: On October 9, 1604, a new star appeared in the sky as bright as any of the planets. Johannes Kepler, who discovered the laws of planetary motion, was one of the astronomers at the time who tried to study this supernova, before telescopes were even invented. Now NASA has turned its Great Observatories (Hubble, Chandra, and Spitzer) on the supernova remnant, and produced an image that shows it in many different wavelengths of light. The combined image shows a bubble-shaped shroud of gas and dust 14 light-years wide expanding at 6 million kph (4 million mph).
