Diffuse Nebula in Sagittarius

View larger image

The Lagoon Nebula is one of the brightest nebulae in the sky, and one of the easiest to see with the naked eye. On summer evenings in the northern hemisphere, it can be seen as an oval patch above the spout of the Sagittarius "teapot."

The Lagoon gets its name from the dark rift that separates the two brightest sections of the nebula. The eastern portion of the nebula (left in this image) contains the open cluster NGC 6530, a group of about 100 stars.
