NGC 6530 is a young open cluster of stars lying around 4,350 light years from Earth in the constellation Sagittarius. The cluster is set within the larger Lagoon Nebula, a large interstellar cloud of gas and dust. This photograph of a portion of NGC 6530 was taken by NASA's Hubble Space Telescope released in 2022, with the Lagoon Nebula giving the image its smoky appearance.Photograph credit: ESA / Hubble / NASA / O.
