Hubble Space Telescope took this "true colour" mosaic image of a small part of the Orion Nebula. You can see expanding plumes of material around young stars and protoplanetary disks.

Protoplanetary disks are rotating disks of dense gas surrounding young stars. Sometimes these disks are a part of the process that creates planets.

The colours in the photo are a composite of seperate images taken at different wavelengths to capture the most abundant elements in the nebula: Hydrogen, Oxygen and Nitrogen.
