Proplyd in Orion Nebula
November 20, 1995 · NASA · Orion Nebula, M42, NGC 1976
This image was taken through a different filter, which blocks any bright spectral emission lines from the nebula, and hence the disk itself is less distinctly silhouetted against the background. However, clearly visible in this image are nebulosities above and below the plane of the disk; these betray the presence of the otherwise invisible central star, which cannot be seen directly due to dust in the edge-on disk.
