❓ Frequently Asked Questions
What is the Hubble Space Telescope?
A space-based telescope launched in 1990 that observes in ultraviolet, visible, and near-infrared light from low Earth orbit, producing sharp images free from atmospheric distortion.
When was it launched and by whom?
Launched on April 24, 1990, aboard the Space Shuttle Discovery, built by NASA with collaboration from the European Space Agency (ESA).
What makes Hubble unique compared to ground-based telescopes?
It orbits above Earth's atmosphere, avoiding atmospheric blur, which allows higher resolution and more stable measurements.
What instruments does Hubble use?
A suite of cameras and spectrographs, including Wide Field Camera 3 (WFC3), Advanced Camera for Surveys (ACS), Cosmic Origins Spectrograph (COS), and Space Telescope Imaging Spectrograph (STIS).
What are some key scientific contributions of Hubble?
Deep-field observations revealing thousands of distant galaxies, refining measurements of the universe's expansion, and advancing studies of star formation, exoplanets, and cosmic evolution.
