A star cluster within a nebula. The background is filled with thin, pale blue clouds. Parts are thicker and pinker in colour. The cluster is made up of bright blue stars that illuminate the nebula around them. Large arcs of dense dust curve around, before and behind the clustered stars, pressed together by the stars’ radiation. Behind the clouds of the nebula can be seen large numbers of orange stars.
