The Chandra X-ray Observatory, one of NASA’s “Great Observatories,” was launched by the Space Shuttle Columbia on July 23, 1999. Named after the Nobel Prize-winning astrophysicist Subrahmanyan Chandrasekhar, Chandra is designed to detect X-ray emissions from extremely hot regions of the universe such as exploded stars, clusters of galaxies, and matter around black holes. As an orbiting telescope, Chandra operates far above the Earth’s atmosphere, which allows for clarity and resolution superior to that achievable from ground-based telescopes. Its high sensitivity makes it possible to observe phenomena such as black holes, quasars, and dark matter, providing valuable insights into the structure and evolution of the universe.
