This is a ROSAT false-color image in X-rays between 500 eV and 1.1 keV of the Chamaeleon I dark cloud. Credit: D Burrows, J Mendenhall, and E Feigelson Penn State University using the US/German ROSAT satellite.

The Chamaeleon complex is a large star forming region (SFR) that includes the Chamaeleon I, Chamaeleon II, and Chamaeleon III dark clouds. It occupies nearly all of the constellation Chamaeleon and overlaps into Apus, Musca, and Carina.

In the image on the right, the contours are 100 µm emission from dust measured by the IRAS satellite.
