Hydra A is a galaxy cluster that is 840 million light years from Earth (redshift = .054). The cluster gets its name from the strong radio source, Hydra A, that originates in a galaxy near the center of the cluster.

Summary

Description	English: Hydra A is a galaxy cluster that is 840 million light years from Earth (redshift = .054). The cluster gets its name from the strong radio source, Hydra A, that originates in a galaxy near the center of the cluster. Optical observations show a few hundred galaxies in the cluster. Chandra X-ray observations reveal a large cloud of hot gas that extends throughout the cluster. The gas cloud is several million light years across and has a temperature of about 40 million degrees in the outer parts decreasing to about 35 million degrees in the inner region.

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	The Chandra X-ray image of Hydra A, a galaxy cluster 840 million light years from Earth, shows strands of 35-40 million degree Celsius gas embedded in a large cloud of equally hot gas that is several million light years across. Also a bright white wedge of hot multimillion degree Celsius gas is seen pushing into the heart of the cluster. As the largest gravitationally bound objects in the universe, galaxy clusters provide crucial clues for understanding the origin and fate of the universe.
