Messier 82 was observed by the NASA/ESA Hubble Space Telescope in 2006, which showed the galaxy’s edge-on spiral disk, shredded clouds, and hot hydrogen gas. The NASA/ESA/CSA James Webb Space Telescope observed the core of Messier 82, capturing in unprecedented detail the structure of the galactic wind and characterizing individual stars and star clusters.

This Webb image shows I Zwicky 18, a blue compact dwarf galaxy some 59 million light-years away in the constellation of Ursa Major. A companion galaxy resides nearby to I Zwicky 18 can be seen at the bottom of the image. The companion may be interacting with the dwarf galaxy and may have triggered that galaxy’s recent star formation. Image credit: NASA / ESA / CSA / Webb / Hirschauer et al.

This image shows Arp 72, a galaxy pair that includes NGC 5996 (large spiral galaxy) and NGC 5994 (its smaller companion, in the lower left of the image). 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. 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 / L. Galbany / J.
