NASA's Spitzer telescope captured this image of Galaxy IC 342, a galaxy about 10 million light years away. Although IC 342 is relatively nearby, as far as these things go, our view of it is obscured by our own galaxy, the Milky Way. Infrared light, shown in the above image, can reach through that obstruction better than visible light. IC 342 has a lower star density than other spiral galaxies. Its stars come through in this image as blue haze. Red indicates the galaxy's dust structures. The large, bright blue stars in the picture's foreground are actually located in the Milky Way.
