ESA’s ISO provides the first view of monstrous stars being born

Massive star forming region as seen by ISO

The ISOSS J18364--0221 region contains two dense cores, each containing enough matter to become at least one massive star. The background image was taken by the Calar Altar 3.5 metre telescope during October 2003 and June 2004. The white contours show cold dust and were taken by the James Clerk Maxwell Telescope during May 2003. The diffuse and elongated emission displayed in green is due to shocked molecular hydrogen (was also observed at Calar Alto) and this traces the outflow of the obscured central source.

The massive star-forming region ISOSS J18364--0221 is in the centre of the image. The data was collected by the Infrared Space Observatory's ISOPHOT's far-infrared camera at 170 micrometres. ISO produced a web of data as it turned from one celestial object to another during its mission.
