Cassiopeia A is a supernova remnant, the remains of an exploded star, about 11,000 light years from Earth. X-rays from Chandra are blue and reveal hot gas, mostly from supernova debris from the destroyed star, and include elements like silicon and iron.
Celestial Imagery from the Chanda X-ray Observatory to Appear in Six Metro Stations
The Smithsonian is partnering with the Art in Transit program of the Washington Metropolitan Area Transit Authority to feature celestial imagery from the Chandra X-ray Observatory at six Metro stations in Washington and Northern Virginia from today, July 18, through October 16.
Operated by the Smithsonian Astrophysical Observatory in Cambridge, Mass., Chandra is the world’s most powerful X-ray telescope, observing the lifecycles of stars and galaxies and producing data used by astronomers across the globe to help understand our universe. As riders take a journey through the Metro system, so too will they embark on a cosmic journey through the deepest regions of outer space, viewing exploding stars, nebulae, black holes and other celestial objects. Chandra images will appear in six stations:
- L’Enfant Plaza
- Metro Center
- Gallery Place – Chinatown
- Farragut North
- NoMa – Gallaudet University
- Crystal City
The Smithsonian believes these images will inspire curiosity among commuters, tourists and all other visitors to the Metro system and encourage them to reconsider the uniqueness and fragility of the planet we call home.
