English: A mosaic of images from WISE in the constellation of Cassiopeia. This region contains a large star forming nebula within the Milky Way Galaxy, called IC 1805 (sometimes called the Heart Nebula), a portion of which is seen at the right of the image. IC 1805 is over 6 thousand light-years from Earth. Also visible in this image are two nearby galaxies, Maffei 1 and Maffei 2. In visible light these galaxies are hidden by dust in IC 1805 and were unknown until 1968 when Paolo Maffei found them using infra-red observations. Both galaxies contain billions of stars and are located some 10 million light-years away (well outside our own Milky Way Galaxy). Maffei 1 is the bluish elliptical object in the centre of the image. It is a Lenticular type galaxy, which has a disk-like structure and a central bulge but no spiral structure or appreciable dust content. Maffei 2 (to the upper left of Maffei 1) is a Spiral type galaxy that also has a disk shape, but with a bar-like central bulge and two prominent dusty spiral arms.

The image size is about 1.6 by 4.5 degrees (The full Moon is about 0.5 degrees across by comparison). Since this is an image of invisible infra-red light, blue is mapped to the WISE 3.4 & 4.6 micron channels and is dominated by star light. Green represents the WISE 12 micron channel, and red is the 22 micron channel, which are dominated by infra-red emission from warm interstellar dust.
