Metadata

This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.

Image title	Chandra has found a "cool" filament of gas in the galaxy cluster Abell 1795. This structure is some 200,000 light years long (the long string-like feature in the middle of this image). The gas in the filament has a temperature of about 30 million degrees Celsius, cooler than the surrounding gas in the cluster. As the gas in the cluster core radiates away its energy, it drifts toward regions where gravity is strongest. The enormous elliptical galaxy located at the head of the filament could have pulled the gas inward into its wake as it passed through the core of the cluster and created the filament.
