Hubble Space Telescope: A Window to the Cosmos

The Hubble Space Telescope launched aboard the Space Shuttle Discovery in 1990.
It orbits about 340 miles above Earth, avoiding atmospheric distortion.
Hubble has taken over 1.5 million observations of planets, stars, and galaxies.
Its images helped measure the age of the universe—about 13.8 billion years.
Hubble’s “Deep Field” images revealed thousands of galaxies in tiny sky patches.
Initially blurry due to a mirror flaw, it was fixed by astronauts in 1993.
Hubble has made breakthroughs in dark energy, galaxy evolution, and exoplanets.
It works in visible, ultraviolet, and near-infrared light.
The telescope has been serviced by astronauts five times, extending its mission life.
Even after three decades, Hubble remains one of the most important tools in astronomy.
