Birthplace of the stars: The integral-shaped filament, the two star clusters above the filament, and cloud L1641 in the south can be seen on these images of the Orion A star formation region. The picture on the left shows a density map compiled with data from ESA's Herschel Space Observatory, the one on the right an infrared image taken by NASA's Wide-field Infrared Survey Explorer (WISE). The photo in the centre is a combination of both images. Image credits: © A. M. Stutz / MPIA.
