Cosmic 'Candy Cane' (Unlabeled) (IMAGE) NASA/Goddard Space Flight Center Caption The central zone of our galaxy hosts the Milky Way's largest, densest collection of giant molecular clouds, raw material for making tens of millions of stars. This image combines archival infrared (blue), radio (red) and new microwave observations (green) from the Goddard-developed GISMO instrument. The composite image reveals emission from cold dust, areas of vigorous star formation, and filaments formed at the edges of a bubble blown by some powerful event at the galaxy's center. The image is about 750 light-years wide.
