Kepler was born on 27 December, the feast day of St John the Evangelist, 1571, in the Free Imperial City of Weil der Stadt (now part of the Stuttgart Region in the German state of Baden-Württemberg, 30 km west of Stuttgart's center).His grandfather, Sebald Kepler, had been Lord Mayor of the city. Astronomers at Las Cumbres Observatory (LCO) are part of an international team of scientists who used NASA's Kepler satellite to catch a rare glimpse of a Type Ia supernova …
Kepler is most remembered for his three laws of planetary motion, which were derived in no small part by using the observational data amassed by Tycho Brahe. NASA Ames manages the Kepler and K2 missions for NASA's Science Mission Directorate. In 1604, Kepler was the court astronomer for emperor Rudolph II in Prague. The explosion of the dying star was initially as bright as Mars and could be seen with the naked eye. NASA's three Great Observatories -- the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory -- joined forces to probe the expanding remains of a supernova. Now, NASA's three Great Observatories — the Hubble Space Telescope, Chandra X-ray Observatory, and Spitzer Space Telescope — have joined forces to look at what Kepler's supernova left behind. This image released Oct. 7, 2004, by NASA shows Kepler's supernova remnant produced by combining data from NASA's Hubble Space Telescope, Spitzer Space Telescope and Chandra X-ray Observatory. "All heavy elements in the universe come from supernova explosions. Chandra X-ray data show different colors in a range from lower to higher energies: red, yellow, green, blue and purple.

JPL managed Kepler mission development. Kepler's famous supernova revealed (pictures) After more than four centuries, new clues emerge pointing to the origins of Kepler's 1604 supernova. Kepler's supernova remnant is thought to be 23,000 light-years away. Optical data (pale yellow and blue) from the Digitized Sky Survey shows stars in the field. For example, all the silver, nickel, and copper in the earth and even in our bodies came from the explosive death throes of stars," said Steve Howell, project scientist for NASA's Kepler and K2 missions at NASA's Ames Research Center in California's Silicon Valley. In 1604, Kepler saw the last supernova observed in our Milky Way galaxy, which he documented two years later in his book De Stella Nova, published in Prague in 1606. The Kepler Extra-Galactic Survey team, led by team member Peter Garnavich, an astrophysics professor at the University of Notre Dame in Indiana, spotted this shock breakout in 2011 Kepler data from a supernova called KSN 2011d, an explosion from a star roughly 500 times the size of our Sun. Kepler's supernova remnant is the debris from a supernova in our galaxy observed in 1604. Why is it called "Kepler's" supernova (and supernova remnant)? Now known as Kepler's supernova remnant, this object was first seen 400 years ago by sky watchers, including famous astronomer Johannes Kepler. That's really difficult -- there's no telling when or where a supernova might happen next. The supernova provided proof to Galileo, Kepler and others that the heavens were not fixed–although they were wrong about what caused the bright star The remnant's of Kepler's supernova …
