Wallpaper: Spitzer's Valentine Rose - Universe Today
Just in time for Valentine's Day, here's a 1024x768 wallpaper of nebula NGC 7129 taken by the Spitzer Space Telescope - it looks like a pink rosebud. Previous images of this nebula taken by optical telescopes just look like a few stars surrounded by a haze of gas. By viewing the nebula in infrared light, astronomers are able to see which stars have swirling rings of material around them that will eventually form planets.
