2	Hubble Vital Statistics HST is in Low Earth Orbit (~600 km) Primary is 2.4 meters Launched in 1990 Regularly serviced Cost ~$2+ billion Suite of changing instruments
3	Hubble to Astronomers Despite the cost, evaluated as most science per dollar. Time Allocated by Orbit Last year, 26000 orbits requested by > 1100 proposals, 5300 orbits approved (250 approved) Cosmology and galaxies usually the big winners.
4	Hubble’s Uncertain Future Jan. 2004, NASA Director Sean O’Keefe announced it was too dangerous to service HST with a shuttle mission (no aborts). Without regular service, HST will fail Gyroscopes & Orbital Decay Service also provides upgrades Computers! Solar panels, etc. Instruments! STIS just failed. Waiting on the “Next Generation” Space Telescope (NGST) renamed the James Webb Telescope
5	The Hubble Law

11	Interacting Galaxies: Cartwheel
12	Interacting Galaxies: Cartwheel
13	Active Galactic Nuclei: AGNs A small fraction of galaxies have extremely bright “unresolved” star-like cores (active nuclei) Shown here is an HST image of NGC 7742, a so-called “Seyfert galaxy” after Carl Seyfert who did pioneering work in the 1940s
