- The Hubble Space Telescope was named after Edwin Hubble, an American astronomist who proved that there are countless galaxies in the universe other than Milky Way, and that the universe is expanding
- Confirmed that cosmic expansion is speeding up due to dark energy Helped scientists calculate the age of the universe Verified existence of black holes in the galactic cores Nailed down links between black holes and quasars Recorded comet Shoemaker-Levy 9 impacting Jupiter and alerted NASA of potential threat to Earth Observed galaxies long ago and far away (deep field) Confirmed that planets begin as disks of dust/gas Traced birth/death of stars and supernova explosions Verified that implosions of giant stars produce GRBs. Analyzed atmospheric composition of planets
