Maffei 1 and 2 peek out from behind the dust
Click the image above for a larger view. Seen toward the upper left in this image, the two galaxies are revealed as a familiar spiral and a glowing blue orb set against the edge of the massive structure of the Heart Nebula, a mere 6,000 light years distant. Because the image data is predominantly infrared the colors we see are mapped from the different infrared frequencies which enables us to see what we normally could not. The blue light is 3.4 and 4.6 micron, and dominated by starlight. The green is 12 micron, and red is 22 micron. If we could see in infrared, these colors are pretty close to what we would see. Now, excuse me while I just stare at this for a while longer.
