  2. Cas A Electromagnetic Spectrum & Great Observatories

  3. Cas A Movie Introduction to Chandra • The Chandra X-ray Observatory is the third of NASA’s “Great Observatories” • Launched July 23, 1999 by Space Shuttle and boosted to high Earth orbit for initial 5 year mission; mission extended to 10 years • Orbits Earth every 64 hours, ranging as far as 140,000 km (87,000 mi) – about 1/3 the way to the moon • Chandra detects astronomical x-rays by focusing them onto detectors by means of nested grazing-incidence mirrors • Chandra’s resolving power is 10 times greater than any previous x-ray telescope • equivalent to the ability to read a stop sign at a distance of twelve miles • Science instruments • 2 imaging cameras, Advanced CCD Imaging Spectrometer (ACIS) and High Resolution Camera (HRC); 2 insertable gratings for more detailed x-ray energy analysis (spectroscopy) • Instruments were developed by Penn State University, MIT, Smithsonian Astrophysical Observatory, and Utrecht

  10. Dark E Parameter Galactic Center

  11. Whim1 NGC 6240 image

  12. NGC 6240 spectra

  13. CDFS Perseus Cluster • Black holes eject a fraction of infalling matter • Ejected matter is detected as radio jets • Jets sweep aside x-ray emitting gas, producing voids • Repetitive outbursts limit the mass of the central galaxy

  14. CDFS Bullet Cluster

  15. Closing Slide Opportunity for exploration and discovery with Chandra remains as high as at launch.
