C24 – Hubble Caldwell 24

This close-up view of the center of Caldwell 24, combining visible and infrared observations taken by Hubble’s Wide Field and Planetary Camera 2 in 1995 and 2001, displays a collision of galactic proportions. A dusty spiral galaxy appears to be rotating on edge, like a pinwheel, as it slides through the larger, brighter galaxy, Caldwell 24. These galaxies are believed to be colliding at over 6 million miles per hour.
