For as long as humans have walked the Earth, the stars have fascinated us. But we have come a long way since the earliest days of astronomy when we had nothing but our eyes to observe the night sky. Since then we have designed an arsenal of ingenious machines to help us unlock the secrets of the stars – from how they work and move around the Universe to how they live and die. For more than 60 years, the Sky at Night has covered every major development in our understanding of the stars, and regular Sky at
