As a new millennium begins we take a look at how our Earth and Moon came to be. Patrick Moore is joined by Professor Chris Kitchin to discuss how distant planets of other suns, ancient meteorites, and devastating collisions between worlds give us clues as to how the Earth and Moon grew from billions of dust grains, each too small to see.

The spacecraft has now collected more information about Mars than all previous missions combined. Patrick Moore is joined by Dr Peter Cattermole to discuss the latest views of our neighbouring planet and where to find Mars in the night sky as it approaches its opposition - a biannual opportunity to observe it at its best.

The Sun has been in the news again, it is at the peak of its 11 year cycle of activity and there have been large solar flares, many sunspots and good displays of aurorae. It has also been eclipsed by the Moon for the first time since the great UK eclipse of 1999. Patrick Moore is joined by Chris Lintott to discuss the Sun, its variability and to look back at some of the eclipses The Sky at Night has seen.

The Earth is constantly bombarded by small fragments of space debris, but somewhere in the Solar System a sizeable asteroid or comet is probably on a collision course with Earth. We don't know where or when the impact will happen but it may prove catastrophic for life on Earth. In the first of two programmes on the subject, Patrick Moore is joined by Jonathan Tate and Lembit Opik to discuss where this threat comes from and assesses the chances of impact from a Potentially Hazardous Object.

Patrick Moore continues his discussion with Jay Tate and Lembit Opik about the threat to the Earth from a Potentially Hazardous Object. They look at the disastrous environmental effects that might happen after a large scale impact, how we are searching the night skies for Near Earth Objects and what could be done to avert disaster.

When Venus is brilliant, the question is often asked: can Venus have been the Star of Bethlehem? The answer is certainly 'no', but we still do not know what the star was, if anything. Patrick Moore is joined by David Hughes and Mark Kidger, who have made careful studies of the records. Can they give a convincing answer?
