To celebrate the 15th anniversary of the launch of the Chandra X-ray Observatory’s launch, the Chandra X-ray Center at the Smithsonian Astrophysical Observatory has released four new images of supernova remnants in their press release of July 22, 2014.
Since its deployment on July 23, 1999, Chandra has helped revolutionize our understanding of the Universe through its unrivaled X-ray vision. One of NASA’s current “Great Observatories,” along with the Hubble Space Telescope and Spitzer Space Telescope, Chandra is specially designed to detect X-ray emission from hot and energetic regions of the universe.
With its superb sensitivity and resolution, Chandra has observed objects ranging from the closest planets and comets to the most distant known quasars. It has imaged the remains of exploded stars, or supernova remnants, observed the region around the supermassive black hole at the center of the Milky Way, and discovered black holes across the universe. Chandra also has made a major advance in the study of dark matter by tracing the separation of dark matter from normal matter in collisions between galaxy clusters. It is also contributing to research on the nature of dark energy.
The four new images of supernova remnants – the Crab Nebula, Tycho, G292.0+1.8, and 3C58 – are very hot and energetic and glow brightly in X-ray light, which allows Chandra to capture them in exquisite detail.
