This image made available by NASA shows the interacting galaxies, NGC 2336, center, and NGC 2937, bottom, known collectively as Arp 142, as their mutual gravitational attraction slowly pulls them closer together. Data from NASA's Spitzer and Hubble space telescopes were combined to show light that spans the visible and infrared parts of the spectrum. The blue streak at the top of the image is an unrelated background galaxy that is farther away than Arp 142. (NASA-ESA/STScI/AURA/JPL-Caltech via AP)
