M42 Center

The image shows the surrounding of the Trapezium cluster at the center of the Orion Nebula. The six brightest stars of the group can be seen in this image. The strong radiation of those stars vaporizes the dense dust clouds that begin to form young stars and planetary systems. These so called proto-planetary disks or Proplyds were discovered by the Hubble Space Telescope at the begin of the century. The image shows a couple of these Proplyds.

Image orientation: North is on the right side.
