Sky seen from an alien world. Computer artwork of the view from the surface of an alien (extrasolar) planet orbiting a star (orange,lower right) that lies within a globular star cluster. A moon is also seen at centre. A globular star cluster is a densely packed ball of thousands to millions of stars formed at the same time.
