    A Galaxy Shines In Every Wavelength

    How do we love spiral galaxy Messier 101? Let us count the ways. We love the Spitzer Space Telescope's infrared image, the Chandra X-Ray Observatory's blue X-ray light, and the Hubble's yellow visible light.

    All three views, in this one composite image, shows how the same features of the galaxy appear in different spectra. The infrared light shows the heat from the galaxy's dust lanes, which follow the same paths as the visible-light stars, which form in those dust lane. Image by AP/NASA)
