Cosmoview Episode 43: Strong-Arming a Galaxy

The overdeveloped spiral arm of the galaxy NGC 772, which was created by tidal interactions with an unruly neighbor, dominates this observation made by astronomers using the Gemini North telescope located near the summit of Maunakea in Hawai‘i. NGC 772’s peculiar appearance has earned it a place as the 78th entry in the Atlas of Peculiar Galaxies — a rogues’ gallery of weird and wonderful galaxy structures.
