Chandra:
NASA's Chandra X-ray Observatory, which was launched and deployed by Space Shuttle Columbia on July 23, 1999, is the most sophisticated X-ray observatory built to date.
Chandra is designed to observe X-rays from high-energy regions of the universe, such as the remnants of exploded stars. The two images of the Crab Nebula supernova remnant and its pulsar shown below illustrate how higher resolution can reveal important new features.
