A Reflection Nebula, A Bok Globule & A Herbig Haro Object | Mayall Telescope

This image was obtained with the wide-field view of the Mosaic camera on the Mayall 4-meter telescope at Kitt Peak National Observatory in Arizona, United States. Also known as Barnard 175, vdB 152 is a reflection nebula atop of a dark Bok globule. Bok globules are isolated and relatively small dark nebulae, containing dense cosmic dust and gas from which star formation may take place. Embedded in the top right side of the nebula is the Herbig Haro object HH 450, a jet emitted from a newly forming star. The thin, red filaments in the upper-right corner of the image are the remnants of a supernova explosion. It is not yet clear whether or not the supernova remnant will collide with vdB 152. The image was generated with observations in the B (blue), V (green), I (yellow) and Hydrogen-Alpha (red) filters. In this image, North is down and East is to the right. 

Herbig–Haro (HH) objects are bright patches of nebulosity associated with newborn stars. They are formed when narrow jets of partially ionized gas ejected by stars collide with nearby clouds of gas and dust at several hundred kilometers per second. Herbig–Haro objects are commonly found in star-forming regions.
