This montage combines data from ALMA with images from the NASA/ESA Hubble Space Telescope, for five distant galaxies.  The ALMA images, represented in red, show the distant, background galaxies, being distorted by the gravitational lens effect produced by the galaxies in the foreground, depicted in the Hubble data in blue. The background galaxies appear warped into rings of light known as Einstein rings, which encircle the foreground galaxies.
