And I love stuff like this so I thought I'd share...

Explanation: By chance, a collision (http://csep10.phys.utk.edu/astr162/lect/galaxies/%20colliding.html) of two galaxies has created a surprisingly recognizable shape on a cosmic scale - The Cartwheel Galaxy (http://antwrp.gsfc.nasa.gov/apod/hubblesite.org/newscenter/newsdesk/archive/releases/%201995/02). The Cartwheel is part of a group of galaxies about 400 million light years away in the constellation Sculptor (http://hawastsoc.org/deepsky/scl/index.html) (two smaller galaxies in the group are visible below and left). Its rim is an immense ring-like structure over 100,000 light years in diameter, composed of star forming regions filled with extremely bright, massive stars. When galaxies collide (http://www.astro.umd.edu/education/astro/gal/%20interact.html) they pass through (http://burro.astr.cwru.edu/models/models.html) each other, their individual stars do not come into contact. However, this ring-like shape is the result of gravitational (http://www.public.iastate.edu/%7Ecurt/cg/%20section1.html) disruption caused by a smaller galaxy (http://antwrp.gsfc.nasa.gov/apod/ap970224.html) passing through a large one, compressing the interstellar gas and dust and causing a a star formation wave to move out like a ripple across the surface of a pond. This false-color composite (http://chandra.harvard.edu/photo/2006/cartwheel/) image of the Cartwheel Galaxy is from space-based observatories. The Chandra X-ray Observatory data is (http://arxiv.org/abs/astro-ph/0407446) in purple, the Galaxy Evolution Explorer (http://www.galex.caltech.edu/ABOUT/about.html) ultraviolet view is in blue, the Hubble Space Telescope visible (http://imagine.gsfc.nasa.gov/docs/science/know_l2/%20emspectrum.html) light picture is in green and the Spitzer Space Telescope infrared (http://coolcosmos.ipac.caltech.edu/) image is in red.
