    en.wikipedia.org/wiki/Chandra_X-ray_Observatory

    Chandra is sensitive to X-ray sources 100 times fainter than any previous X-ray telescope, enabled by the high angular resolution of its mirrors. Since the Earth's atmosphere absorbs the vast majority of X-rays , they are not detectable from Earth-based telescopes ; therefore space-based telescopes are required to make these observations.

    en.wikipedia.org/wiki/STS-93

    The primary objective of the STS-93 mission was to deploy the Chandra X-ray Observatory (formerly the Advanced X-ray Astrophysics Facility) with its Inertial Upper Stage booster. At its launch, Chandra was the most sophisticated X-ray observatory ever built. It is designed to observe X-rays from high energy regions of the universe, such as hot ...
