10. The Launch of the Hubble Space Telescope (1990)
On April 15, 1990, the Space Shuttle Discovery launched the Hubble Space Telescope into orbit. Hubble has since provided unprecedented images and data about the universe, transforming our understanding of astronomy and cosmology. It has helped determine the rate of expansion of the universe, captured stunning photos of distant galaxies, and studied phenomena like black holes and nebulae. The telescope’s success has led to numerous scientific breakthroughs and inspired generations of scientists and space enthusiasts. Despite occasional technical issues, Hubble remains active and continues to contribute valuable knowledge about the cosmos.
