Astronomy Tuesday

So much universe, indeed.

This is just our infinitesimally small corner of it, the center of the Milky Way galaxy. This false color photograph, taken in infrared by the Spitzer Space Telescope, shows the stars that are usually obscured by space dust. The blue lights indicate older, cooler stars, but the glowing red portions are stellar nurseries where young stars are going through their hot-headed adolescence.

So many stars. Really, the only appropriate response is Wow.
