This Hubble image shows NGC 2608, a barred spiral galaxy located 64 million light-years away in the constellation Cancer. The picture was created from images taken with Hubble’s Wide Field Camera 3 (WFC3). It combines observations gathered in four different filters, bringing together visible and infrared light to show off this galaxy in all its glory. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / A. Riess et al.

Abell 2384 contains the giant structures that can result when two galaxy clusters collide. A superheated gas bridge is seen in this composite image with X-rays from Chandra and XMM-Newton (blue), radio emission from the Giant Metrewave Radio Telescope (red) and optical data from the Digitized Sky Survey (yellow). This multi-wavelength view reveals the effects of a jet shooting away from a supermassive black hole in the center of a galaxy in one of the clusters. The jet is so powerful that it is bending the shape of the gas bridge, which extends for over 3 million light-years and has the mass of about 6 trillion solar masses.
