Visible and Invisible


Cat's PawThis comparison of infrared and visible views of the Cat’s Paw Nebula uses images taken by two of the telescopes belonging to the European Southern Observatory. The visible light image (right) was taken with the Wide Field Imager on the 2.2-m MPG/ESO telescope at La Silla in Chile. The new infrared image (left) was taken with the VISTA telescope at ESO’s Paranal Observatory. In the infrared, the dust that hides many stars is almost transparent, allowing many more stars to be seen.
