The Milky Way, made up of countless faint stars, can easily be seen in the evening sky this month. Tonight Patrick Moore describes this luminous band which stretches from one horizon to the other, and explains how it forms part of the huge Galaxy of stars in which we live. The latest news will also be given of Mariner 10, the space probe now nearing Mercury, which on 29 March should send back the first close-range pictures of the planet's surface.

During 1974 there have been some important and spectacular space missions. In the spring Mariner 10 sent back the first close-range pictures of cloud-covered Venus and crater-scarred Mercury. Then, early in December, Pioneer II made a close rendezvous with Jupiter, the only planet known to have a tremendously powerful magnetic field. Pioneer will now travel on to Saturn, which it should reach in 1979. All these probes have given us vital new information about the Solar System. Patrick Moore discusses with Dr Garry Hunt the most important results of the Year of the Planets.
