Bok globule
subjectfact 
Bok globulehas radius 103 to 105 AUhas source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, 2001-09-27 09:30:10.0
is a part of dust2001-09-27 09:30:10.0
has definition A compact, spherical dark nebula that absorbs radiation. Estimates of their mass suggest that their density is too low for gravitational collapse. They tend to lie in regions of much dust but less gas than would be expected for star-forming regions.has source: Hopkins, J. 1976 Glossary of Astronomy and Astrophysics, University of Chicago Press, 2001-09-27 09:30:10.0
