The Pleiades in IR


Pleiades_WISEOne of my favorite objects in the autumn sky is the Pleiades. This false-color image shows the star cluster as seen through the eyes of WISE, the Wide-field Infrared Survey Explorer. It’s a mosaic of several hundred images from the more than one million WISE captured in its first survey of the entire sky in infrared light.

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