Hubble image of Arp 142, also known as NGC 2936 and NGC 2937, or the Penguin and the Egg.
Gravitational interactions between the two galaxies warped the spiral's orderly disk. Gas and dust were compressed during the encounter, triggering star formation, visible as bluish knots of young stars along the distorted arms closest to the companion elliptical.
