Light from a few foreground stars seen in the WFPC2 image provides only a hint of the many other stars embedded in this dense cloud. Here, stars and glowing interstellar dust, heated by and scattering the intense starlight, appear yellow-orange. Emission by excited hydrogen molecules appears blue. The image is oriented with north up and east to the left. The diagonal extent of the image is about 0.4 light-years.
Some details are as small as the size of our solar system.
