Peering deep into the heart of the Milky Way, this image shows a region of the sky in the constellation of Sagittarius. The two knots of stars you see are the globular clusters NGC 6522 (upper right) and NGC 6528 (lower left). There are over 200,000 stars in this image alone which covers a patch of sky just two-thirds as wide as the full moon.
The vastness of the cosmos is staggering.
