SUMMARY: NASA's Spitzer space telescope has taken a new mosaic image of the familiar Andromeda galaxy. Under Spitzer's infrared vision, the galaxy is a contrast of old stars and knots of gas and dust heated by younger stars. Although it looks like a single image, Spitzer took 3,000 individual frames, which were then stitched together on computer to produce this final mosaic. Andromeda is much larger than our own Milky Way galaxy, and contains roughly 1 trillion stars.

3000 individual frames. That must have taken some time to assemble. It is interesting looking at the image to see that some of the dust-lanes are obviously distorted, presumably from recent mergers.

Wow, that's something else...I didn't think that Andromeda was that big, sheesh.
