The Infrared Sky

Moon Rills
The moon is a world of mountains, craters, valleys, peaks and huge waterless seas. Of special interest are the cracklike features known as rills, which are unlike anything we find on earth. Patrick Moore talks about them to Dr Lionel Wilson of the University of Lancaster, who has been making a careful study of these remarkable lunar features.

Little Worlds
During its voyage to Jupiter, the American Galileo probe will survey a small and interesting world, the asteroid Amphitrite - one of the swarm of minor planets moving round the sun between the orbits of Mars and Jupiter. Patrick Moore talks about the Amphitrite encounter, and about the whole swarm of these little worlds which were once referred to by a German astronomer as 'vermin of the skies'.

The Computerised Amateur
Many amateur astronomers have large telescopes but Ron Arbour 's observatory, near Winchester, is exceptional; his 16-inch reflector is computer controlled and is programmed to hunt automatically for stellar explosions far across the universe. Patrick Moore visits the observatory to talk to Ron Arbour about his telescope and about his plans for photographing Halley's Comet later this year; during the programme he attempts to get a photograph of the comet specially for The Sky at Night.

Red Shift - Or Red Herring?
How large is the universe? Astronomers measure the distances of very remote objects by using spectroscopes, but today there are some doubts as to whether the measurements are reliable. Two star-systems in the constellation of the Fishes appear to give very confusing results. Patrick Moore talks to Iain Nicolson about these new results and what they may mean.

The Comet Returns
Halley's Comet is now back and can be seen with binoculars, and should be visible with the naked eye next month. Patrick Moore talks to Douglas Arnold (photographing the comet);
Brian Harpur (Halley Comet Society), Lee Sproates (a young amateur astronomer), and Dr Rod Jenkins of British Aerospace, who built the probe that will go right into the comet next March.

How Wrong We Were
The science of astronomy is thousands of years old. Yet only in the last few decades have astronomers made discoveries that have proved the old theories wrong. Venus has no water - Mars has no canals - Man did not sink without trace into the moon's dust. Patrick Moore tells the stories of these old theories, and explains how, because of one mistake, the size of the universe was doubled.
