The Sky At Night: 21x1
Sirius, the Dog-Star
Sirius is now at its best in the evening sky. It is one of our nearest stellar neighbours, and is much more luminous than the sun. It seems to flash all colours but is really a white star, it has a strange, super-dense White Dwarf companion. Patrick Moore and lain Nicolson discuss some of the questions associated with Sirius.
