In this crowded starfield lies a dusty cosmic cloud nicknamed the "Dark Tower." Star formation is likely occurring in this dark nebula that is nearly 40 light-years across. This swept-back cloud is termed a cometary globule and is created by intense UV radiation from an OB association. This structure is about 5,000 light-years away.Friday, May 9, 2008
