NASA's WISE captured this image of a hidden star-forming cloud of dust and gas located in the constellation of Cepheus. The dust blocks visible light passing through, and the cloud and its contents are mostly hidden when viewed in visible light. What appears to the naked eye as the blackness of space is in fact a dark nebula. WISE's infrared vision both penetrates the dust to see stars within the cloud as well as the glow of the dust that makes up the cloud. Different parts of this nebula have a variety of names in astronomical catalogs. The central portion is known as IRAS 22298+6505. Other portions of this cloud are called TGU H686 P2 and LDN 1213. The surveys that produced these catalogs were often done with fields of view that were much smaller than WISE's. What looked like distinct nebulae in those surveys are revealed as a much larger cloud complex by WISE. Seen in the upper central part of this image, 26 Cephei is surrounded by a bubble of cool, red dust and dust-enshrouded younger stars that may owe their existence to their older sibling. Color in this image is representational. Blue and cyan represent light at 3.4 and 4.6 microns, primarily emitted by stars. Green and red represent light at 12 and 22 microns, emitted by cooler dust particles in the dark clouds.
