This Hubble image shows the Serpens Nebula, a stellar nursery about 1,300 light-years away. Within the nebula, in the upper right of the image, a shadow is created by the protoplanetary disk surrounding HBC 672. While the disk of debris is too tiny to be seen even by Hubble, its shadow is projected upon the cloud in which it was born. In this view, the feature, the Bat Shadow, spans approximately 200 times the diameter of our own Solar System. Image credit: NASA / ESA / STScI.
