Spitzer: The Non-Adulterous-Governor Edition

NASA's Spitzer Space Telescope (a.k.a. Hubble's jealous little brother) has been putting together a mosaic of the Milky Way Galaxy for the past year for exhibition at the Adler Planetarium in Chicago. The prototype image was released this week, and it allows us to view our galaxy in unprecedented ways:
As inhabitants of a flat galactic disk, Earth and its solar system have an edge-on view of their host galaxy, like looking at a glass dish from its edge. From our perspective, most of the galaxy is condensed into a blurry narrow band of light that stretches completely around the sky, also known as the galactic plane.
The image is composed of over 800,000 separate images, each of them hi-res, each likely showing more detail than your average desktop wallpaper. Aside from the mosaic at Adler, the images will also allow astronomers to do statistical searches, estimate populations of objects and evaluate the contexts of celestial objects.

  1. Pretty neat stuff. So what does this telescope mean for astronomy? What can we now find out from it about the Milky Way Galaxy that couldn't get before?
