DWB111. La Nebulosa de la Hélice
Nebulosa de emisión en la constelación del Cisne

Also known as Simeis 57, this nebula is part of a much larger ionized hidrogen cloud. Its shape, as can be seen at the middle of the image, sugest a propeller. The origin of this peculiar structure is still totally unknown and its distance to Earth as well as its excitation source are also undetermined.
