With colors reminiscent of Faberge, the Cartwheel galaxy stands out against a backdrop of other brightly-colored galactic bodies. This galaxy's Easter egg appearance's due to false colors representing various wavelengths of light — ultraviolet(blue), B-band visible light(green), infrared(red), and x-ray(purple). This galaxy's 'rings' are aftermath of the Cartwheel's collision w/ another galaxy 100 million years ago. The neon blob & green spiral (background) are two other galaxies.
The caterpillar-shaped knot, called IRAS 20324+4057, is a protostar in a very early evolutionary stage. It is still in the process of collecting material from an envelope of gas surrounding it. The object lies 4,500 light-years away in the constellation Cygnus. - http://www.nasa.gov/content/goddard/nasa-s-hubble-sees-a-cosmic-caterpillar/#.U_Ej7_l5OSr - via Aftab khAn's photo on Google+
