Barnard 3 is a dusty, gassy region about 1000 light years away. Near the center is a F2 white-yellow star HD 278942 which is brighter and hotter than our Sun, and is flooding the surrounding material with ultraviolet light. The UV from the star is making the gas glow. Some other nebulae could be found on this image (see mouseover). The blue light at the top right is from the star o Persei. A two panel mosaic showing Barnard 3 and VdB 19 and o Persei can be seen below:
