The gruesome palette of these galaxies is owed to a mix of mid-infrared light from NASA’s James Webb Space Telescope, and visible and ultraviolet light from NASA’s Hubble Space Telescope. The pair grazed one another millions of years ago. The smaller spiral on the left, cataloged as IC 2163, passed behind NGC 2207, the larger spiral galaxy at right.
Both have increased star formation rates. Combined, they are estimated to form the equivalent of two dozen new stars that are the size of the Sun annually. Our Milky Way galaxy forms the equivalent of two or three new Sun-like stars per year.
Both galaxies have hosted seven known supernovae, each of which may have cleared space in their arms, rearranging gas and dust that later cooled, and allowed new many stars to form. (Find these areas by looking for the bluest regions).
Examine the galaxies’ radically white appearance in mid-infrared light, and compare the Hubble and Webb images side by side.

| About The Data | |
| Data Description | This image was created with Hubble data from proposal: (D. Elmegreen) and Webb data from proposal (M. Garcia Marin). Image Processing: Joseph DePasquale (STScI) |
| Instrument | Hubble: WFPC2; Webb: MIRI |
| Exposure Dates | Hubble: May 25, 1996; November 11, 1998; Webb: January 26, February 2, 2024 |
| Filters | Hubble: F439W, F555W, F814W; Webb: F770W, F1130W, F1500W |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the Hubble and James Webb space telescopes using Hubble's WFPC2 and Webb's MIRI instruments. Several filters were used to sample wide wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue: F439W Green: F555W Red: F814W, Orange: F770W + F1130W + F1500W |
| About The Image | |
| Compass and Scale Image | An astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made. |
