Swan Nebula: When you look at the brighter parts of this emission nebula from the left hand side it looks somewhat like a swan. This is where the name is derived  from. Exactly these parts are also a gigantic star-burst area, which means that extremely bright young stars are illuminating the hydrogen gas, some of them still enshrouded in the dust and gas cloud, which was their stellar nursary.

The image was taken at the observatory of IAS at Hakos Farm in Namibia.
