Deep Space Objects

NGC 3576 contains several clusters as star propagation has progressed sequentially east to west during the last several million years. The bright emission component extends some 100 light years across and contains scattered small dark nebulae known as Bok Globules. Bok Globules are dense well defined concentrations of gas and dust named after the Dutch astronomer Bart Bok (1906-1983) who first defined them. Typically they possess 10 to 50 solar masses within a space of a single light year. Most commonly found within HII regions they are known to be cocoons of star formation, particularly the formation of double or multiple star systems. Text courtesy Rob Gendler.

Deep Space Objects

Amateur astronomer Bill Snyder has been involved with astrophotography since 2007. Once he takes his pictures with a camera and a telescope, the data must be processed to produce the colorful images seen in this slide show. He recently acquired a Apogee U8300 CCD camera, an Orion Atlas EQG computerized mount and a TMB SS 130mm telescope which has been installed in his home observatory in Pittsburgh, Pa. Snyder also works with Martin Pugh at Heavens Mirror Observatory at the Sierra Remote Observatory complex in the Sierra Nevada Mountains in California. (Yahoo News)
