Stardust in Perseus
http://apod.nasa.gov/apod/ap070511.html
This picture shows a region of dust, gas, and stars in the direction of Perseus. Several reflection nebulae are visible in the picture. The largest blue shape is NGC 1333, which is a bright emission and reflection nebula. NGC 1333 is a star-forming region; it contains hundreds of young stars. The red area next to NGC 1333 is hydrogen released by forming stars. Dark dust nebulae are also visible in the picture; these nebulae obscure newly-formed stars and protostars.
