If We Could See IR

M83VisibleandIRj.pgThe picture on the left is galaxy M83 as we see it in visible light. The image on the right is what it would look like we could see infrared light as well. The visible light image was taken with the Wide Field Imager on the 2.2-metre MPG/ESO telescope at La Silla in Chile. The infrared image was taken with the HAWK-I instrument on the VLT at ESO’s Paranal Observatory. In infrared the dust that hides many stars is nearly transparent, making the spiral arms less dramatic but revealing a whole host of new stars that are otherwise invisible.
