Spitzer Finds More than 100 New Star Clusters - Universe Today
NASA's Spitzer Space Telescope has found more than 100 new star clusters hidden within the dusty areas of our own Milky Way. The powerful infrared observatory can see through the dark dust that normally obscures our view of this region of the galaxy. The team of astronomers that made the discovery found that there are twice as many clusters in the southern galactic plane (visible from the southern skies) as there are from the northern galactic plane. This may offer hints about the location of the Milky Way's spiral arms.
