The Orion Nebula Cluster
March 17, 2003
This image shows a ROSAT HRI-observation of the Orion nebula region (data taken from the ROSAT data archive; see Gagne et al. 1995, ApJ 445, 280 for a detailed analysis). The field of view is about 40 x 40 arcmin, centered on the Trapezium. The very strong source near the upper edge is the star P1724. This star showed a giant X-ray flare during the ROSAT observation, probably the most energetic X-ray flare ever observed.
