Satellite Dish At Night. The Hubble Space Telescope: A Legacy of Discovery.
History of the Hubble Space Telescope. [image]. Launched April 24, 1990 aboard Space Shuttle Discovery Joint project between NASA & ESA Designed to avoid Earth’s atmosphere distortion Five servicing missions (1993–2009) upgraded instruments.
Instruments & Frequency Bands. [image]. Wide Field Camera 3 (WFC3): UV, visible, near-infrared Advanced Camera for Surveys (ACS): Visible light Cosmic Origins Spectrograph (COS): Ultraviolet Near Infrared Camera & Multi-Object Spectrometer (NICMOS) (retired).
Major Discoveries. Age of the Universe: ~13.8 billion years Evidence of dark energy (accelerating expansion) First direct images of exoplanet atmospheres Iconic images: Pillars of Creation, AG Carinae, Deep Field surveys.
Upgrades & Future Plans. 1993 corrective optics repair New cameras & spectrographs added in later missions Operated alongside James Webb Space Telescope (JWST) Expected to function through the 2030s.
Limitations & Constraints. Limited by Earth orbit (cannot see far infrared/radio waves) Costly servicing missions (last one in 2009) Instruments slowly aging Susceptible to hardware failures.
Conclusion. Over 1.5 million observations Over 20,000 scientific papers published Changed our understanding of galaxies, stars, and cosmic evolution Legacy: Inspiring future generations of astronomy.
