By combining data from NASA?s James Webb Space Telescope and NASA?s Hubble Space Telescope, researchers were able to trace light that was emitted by the large white elliptical galaxy at left through the spiral galaxy at right and identify the effects of interstellar dust in the spiral galaxy. This image of galaxy pair VV 191 includes near-infrared light from Webb, and ultraviolet and visible light from Hubble. Webb?s near-infrared data also show us the galaxy?s longer, extremely dusty spiral arms in far more detail, giving them an appearance of overlapping with the central bulge of the bright white elliptical galaxy on the left. Although the two foreground galaxies are relatively close astronomically speaking, they are not actively interacting. Don?t overlook the background scenery! Like many Webb images, this image of VV 191 shows many galaxies that lie great distances away. For example, two patchy spirals to the upper left of the elliptical galaxy have similar apparent sizes, but show up in very different colors. One is likely very dusty and the other very far away, but researchers need to obtain data known as spectra to determine which is which.

Magnetic fields in NGC 1068, or M77, are shown as streamlines over a visible light and X-ray composite image of the galaxy from the Hubble Space Telescope, the Nuclear Spectroscopic Array, and the Sloan Digital Sky Survey. The magnetic fields align along the entire length of the massive spiral arms ? 24,000 light years across (0.8 kiloparsecs) ? implying that the gravitational forces that created the galaxy?s shape are also compressing its magnetic field. This supports the leading theory of how the spiral arms are forced into their iconic shape known as ?density wave theory.? SOFIA studied the galaxy using far-infrared light (89 microns) to reveal facets of its magnetic fields that previous observations using visible and radio telescopes could not detect.
