X-ray Sources in the Vicinity of the Constellation OrionThis computer image shows the point-like X-ray sources of the ROSAT Survey in a clipping of about 50 × 75 square degrees in the vicinity of the constellation Orion. The colours produce an overview of the X-ray spectra taken with the PSPC, whereby the colour changes from yellow to white to blue with increasing hardness of the radiation, akin to the visible-light colour change of stars from yellow to blue with increasing temperature. The ROSAT sky is characterized by its great variety of objects located at very different distances: from the nearby Moon (small sickle in the upper part of the image) and sun-like stars, white dwarfs, neutron stars and supernova remnants in our Milky Way and nearby galaxies out to clusters of galaxies and quasars at the edge of the Universe.
