Hubble Uncovers Surprisingly Complex Structures in Radio Galaxies

August 7, 1995: Probing some of the most distant and energetic galaxies in the universe, the Hubble telescope has uncovered surprisingly varied and intricate structures of stars and gas, suggesting that the processes powering these so-called radio galaxies are more complex than previously thought.

The radio galaxies observed are far across the cosmos, existing when the universe was half its present age. Light from these galaxies is just now reaching Earth. The Hubble observations should shed light on galaxy evolution and on the nature of active galaxies, which may be powered by immense black holes at their cores. These Hubble images, combined with radio maps produced by the Very Large Array Radio Interferometer [blue contour lines], show surprisingly varied and intricate structures of gas and stars.
