Chandra X Ray Observatory site - Dark matter
Type of Spiritual Experience
NASA's Chandra X-ray Observatory is a telescope specially designed to detect X-ray emission from very hot regions of the Universe such as exploded stars, clusters of galaxies, and matter around black holes. Because X-rays are absorbed by Earth's atmosphere, Chandra must orbit above it, up to an altitude of 139,000 km (86,500 mi) in space. The Smithsonian's Astrophysical Observatory in Cambridge, MA, hosts the Chandra X-ray Center which operates the satellite, processes the data, and distributes it to scientists around the world for analysis. The Center maintains an extensive public web site about the science results and an education program.
Since its launch on July 23, 1999, the Chandra X-ray Observatory has been NASA's flagship mission for X-ray astronomy, taking its place in the fleet of "Great Observatories."
A description of the experience

The next chunk ….. is another unknown: dark matter. Of all of the material we know about because we can see its gravitational effects, about 85% is composed of matter that emits no light and is radically different from material found in planets and stars. X-rays can be used to study the effects of dark matter in a variety of astronomical settings, and thus probe the nature of this mysterious substance that pervades the Universe.
Our small piece of the pie is the remaining 4% of the Universe containing everything we can see with our eyes and telescopes. This includes all intergalactic and interstellar gas and dust, stars, planets, and life. Before dark matter was discovered in the 1930s, this 4% was our entire Universe. Scientists now use their telescopes and computers to learn ever more about the exciting objects and phenomena in the observable cosmos, but also to glimpse through keyholes into the much larger Dark Universe
