Hubble Space Telescope launched - Test
- 1. The Hubble Space Telescope, one of the most significant achievements in the field of astronomy, was launched into low Earth orbit on April 24, 1990, aboard the Space Shuttle Discovery (STS-31). Designed to observe astronomical objects free from the distortions of Earth's atmosphere, Hubble has provided astronomers with unparalleled images and data, revolutionizing our understanding of the universe. Once in space, the telescope quickly began sending back stunning photographs of galaxies, nebulae, and other celestial phenomena, including the breathtaking Pillars of Creation in the Eagle Nebula. Hubble's ability to capture light from distant stars allowed scientists to measure the expansion of the universe, contributing to the groundbreaking discovery of dark energy. Through a series of servicing missions over the years, Hubble has been upgraded with advanced instruments and technology, ensuring its continued operation and relevance. The telescope has not only deepened our knowledge of the cosmos but has also inspired public interest in astronomy, affirming its status as a symbol of human ingenuity and exploration.
