Brilliant comets have been rare over recent years, but Austin's Comet, now brightening as it moves into the northern part of the sky, may become really spectacular, with a bright head and a long tail. In this programme Patrick Moore is joined by Harold Ridley , one of Britain's leading observers of comets, to explain what, hopefully, is in store during the coming weeks.

A Brown Dwarf is like a missing link - not quite a star and yet too big to be a planet. A team including Dr Mike Hawkins of Edinburgh's Royal Observatory may have located the first definite Brown Dwarf.

The sun, our nearest star, is at present at the peak of its cycle of activity and there are many sunspots. These can be observed by amateurs, though great care must always be taken. Patrick Moore is joined by Bruce Hardie , director of the Solar Section of the British Astronomical Association. He also visits the Swedish solar telescope in La Palma, where remarkable pictures of the sun are being taken.

At the moment the planet Venus is a brilliant object in the east before dawn. It is a world much the same size as the Earth, but very different in many ways, with its fiercely hot surface, its dense, choking atmosphere and its clouds of corrosive acid. Maps of its surface have to be compiled by radar. In this programme, Patrick Moore and Dr Peter Cattermole describe how the new radar-carrying spacecraft Magellan, which reaches Venus this month, will continue this work.

Radiations of very short wavelength from space cannot reach the Earth because they are blocked by the atmosphere, but they are of increasing importance to astronomers. ROSAT, an artificial satellite designed specially for this research, is now sending back exciting information. Professor Ken Pounds of Leicester University and Patrick Moore discuss the latest results.
