This Hubble image shows NGC 3783, a barred spiral galaxy some 135 million light-years away in the constellation of Centaurus. The color image is composed of infrared and optical observations from Hubble’s Wide Field Camera 3 (WFC3). It is based on data obtained through five filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / M.C. Bentz / D.J.V. Rosario.

A slice of the 3D map of galaxies collected in the first year of the DESI survey with annotations identifying key features in the map. Earth is at the tip, with the furthest galaxies plotted at distances of 11 billion light-years. Each point represents one galaxy. This version of the DESI map includes 600,000 galaxies -- less than 0.1% of the survey’s full volume. Image credit: DESI Collaboration / NOIRLab / NSF / AURA / R. Proctor.

This Hubble image shows IC 4633, a spiral galaxy some 100 million light-years away in the constellation of Apus. 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 (DECam), which is mounted on NSF’s Víctor M. Blanco 4-m telescope at Cerro Tololo Inter-American Observatory in Chile. Five 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 / L. Galbany / J.
