This video begins with a view of the constellation Leo in the night sky. The head and mane of the lion are outlined by a curving arc of stars including Algenubi, Rasalas, Adhafera, and Algieba. Extending this arc down to the bright star Regulus creates the asterism known as "The Sickle". The hindquarters of the lion are represented by a triangle of bright stars, with Denebola at the tail. Regulus and Denebola are, respectively, the 21st and 60th brightest stars in the night sky. | Space Telescop
