The Hubble Space Telescope, launched by NASA in 1990, has revolutionized our understanding of the universe. One of its major discoveries was the determination of the precise age of the universe, approximately 13.8 billion years old. The Hubble Telescope also provided evidence for the existence of supermassive black holes at the centers of galaxies, which has significantly advanced our knowledge of how galaxies evolve over time. Another key discovery made by the Hubble Space Telescope was the proof of dark energy, a mysterious force causing the universe's expansion to accelerate. This finding fundamentally changed our understanding of the cosmos and has led to the development of new theories in cosmology. Additionally, the Hubble Telescope has captured stunning images of distant galaxies, supernovae, and other celestial phenomena, allowing scientists and the public alike to marvel at the beauty and complexity of the universe. In conclusion, the Hubble Space Telescope has been instrumental in expanding our knowledge of the cosmos and continues to provide valuable insights into the nature of the universe. Its groundbreaking discoveries have shaped our understanding of the universe and will continue to inspire future generations of astronomers.
