Topics include stellar life cycles, radio astronomy, artificial satellites, black holes, neutron stars and many others.

"[8] Many of the world's leading astronomers have appeared on the show through the years, including Harlow Shapley (the first to measure the size of the Milky Way galaxy), Fred Hoyle, Carl Sagan,[9] Jocelyn Bell Burnell, Samuel Tolansky, Harold Spencer Jones, Martin Ryle, Richard Ellis, Carlos Frenk and Bart Bok.

[citation needed] Many well-known astronauts have also appeared on the programme, such as Piers Sellers, Eugene Cernan, Buzz Aldrin and Neil Armstrong.

In September 2013 the BBC announced that the programme's future after December 2013 was under review, prompting speculation that the corporation would end it, and a petition asking for the show to be retained.

In February 2007, the Royal Mail issued a set of six astronomy stamps to celebrate the 50th anniversary of the programme.
