Panning across the star formation region NGC 6559

The Danish 1.54-metre telescope located at ESO���s La Silla Observatory in Chile has captured a striking image of NGC 6559, an object that showcases the anarchy that reigns when stars form inside an interstellar cloud. This pan video gives us a close-up view of this region of sky, which includes glowing red clouds of mostly hydrogen gas, blue regions where starlight is being reflected from tiny particles of dust and also dark regions where the dust is thick and opaque.
