This Hubble image shows IC 438, a spiral galaxy some 130 million light-years away in the constellation of Lepus. The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

Two spiral galaxies, NGC 6040 and NGC 6039, are merging together at the right side of this Hubble image. NGC 6039 is seen face-on and is circular in shape. NGC 6040 seems to lie in front of the first one. In the lower-left corner, cut off by the frame, the elliptical galaxy NGC 6041 -- a central member of the galaxy cluster that Arp 122 resides in -- appears as light radiating from a point. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) and the Dark Energy Camera, which is mounted on NSF’s Víctor M. Blanco 4-m telescope at Cerro Tololo Inter-American Observatory in Chile. Four filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / J. Dalcanton / Dark Energy Survey / DOE / FNAL / DECam / CTIO / NOIRLab / NSF / AURA / L. Shatz.

Enceladus’ tiger stripes are known to be spewing ice from the moon’s icy interior into space, creating a cloud of fine ice particles over the moon’s south pole and creating Saturn’s mysterious E-ring. Evidence for this has come from NASA’s Cassini spacecraft that orbited Saturn from 2004 to 2017. Pictured here, a high resolution image of Enceladus is shown from a close flyby. Tiger stripes are visible in false-color blue. Image credit: NASA / ESA / JPL / SSI / Cassini Imaging Team.
