NGC 6240 is an ongoing collision of two gas-rich disk galaxies. More information about this image is available at UCSC. - UCSCW. M. Keck Observatory NGC 6240
Galaxy cluster Abell 2218 is acting as a powerful lens, magnifying all galaxies lying behind the cluster’s core. The lensed galaxies are all stretched along the shear direction, and some of them are multiply imaged. Those multiple images usually appear as pair of images with a third—generally fainter—counter image, as is the case for the very distant object. - ESA, NASA, J.-P. Kneib (Caltech/Observatoire Midi-Pyrenees) and R. Ellis (Caltech) Galaxy Cluser “ABELL”

The central starburst region of the dwarf galaxy IC 10. In this composite color image, near infrared images obtained with the Keck II telescope have been combined with visible-light images taken with NASA’s Hubble Space Telescope to reveal distinct populations of red and blue stars. - UC Berkeley/NASA/W. M. Keck Observatory Irregular Dwarf Galaxy IC 10
Keck II telescope adaptive optics image of the core of the Cygnus A radiogalaxy, one of the most spectacular nearby double-lobed radio sources in the sky. - Lawrence Livermore National Lab/W. M. Keck Observatory Cygnus A
This galaxy (CDF-S:[MBR2003]H_0941) contains two nuclei, indicating a recent galaxy-galaxy collision. The right-hand nucleus is slightly bluer than its partner. The galaxy is an X-ray source and is 4.6 billion light years away. This three color image combines optical light from the Hubble space telescope with infrared light from the Keck laser guide star system. - Hubble Space Telescope/W. M.
