The Wide-field Infrared Survey Explorer, or WISE, has seen a cluster of newborn stars enclosed in a cocoon of dust and gas in the constellation Camelopardalis. The cluster, AFGL 490, is hidden from view in visible light by the cloud. But WISEs infrared vision sees the glow of the dust itself, and penetrates this dust to see the infant stars within.

Not much is known about this stealthy star cluster. Its distance from Earth is estimated to be about 2,300 light-years. The portion of the star-forming nebula captured in this view stretches across about 62 light-years of space.

All four infrared detectors aboard WISE were used to make this mosaic. Color is representational: blue and cyan represent infrared light at wavelengths of 3.4 and 4.6 microns, which is dominated by light from stars. Green and red represent light at 12 and 22 microns, which is mostly light from warm dust.
