Triple delight in milky way
NASA has blended three views of our home galaxy’s turbulent core to produce a picture filled with scientifically significant snap, crackle and pop. And the deeper you go into the image, the more you learn.

The result is an amazingly detailed, and amazingly colorful, multiwavelength view of our galaxy’s core, 26,000 light-years away in the constellation Sagittarius.
