This Hubble image shows NGC 4694, a lenticular galaxy some 54 million light-years in the constellation of Virgo. The color image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the ultraviolet, near-infrared, and optical parts of the spectrum. It is based on data obtained through six filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

In this image of the barred spiral galaxy NGC 5668, Hubble was used to examine the surroundings of the Type II supernova event labeled SN 2004G, seeking to study the kinds of stars that end their lives as this kind of supernova. The color image is composed of near-infrared and optical observations from Hubble’s Advanced Camera for Surveys (ACS). Two 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 / C. Kilpatrick.

The galaxy cluster MACS-J0417.5-1154 is so massive it is warping the fabric of space-time and distorting the appearance of galaxies behind it, an effect known as gravitational lensing. This natural phenomenon magnifies distant galaxies and can also make them appear in an image multiple times, as Webb saw here. Two distant, interacting galaxies -- a face-on spiral and a dusty red galaxy seen from the side -- appear multiple times, tracing a familiar shape across the sky. Active star formation, and the face-on galaxy’s remarkably intact spiral shape, indicate that these galaxies’ interaction is just beginning. Image credit: NASA / ESA / CSA / STScI / V.
