The finalists for the Astronomy Photographer of 2009 award are in.
This picture by Australia's Ted Dobosz uses a 30-minute exposure to capture the Earth spinning. Stars make trails around the South Pole and the bottom of the photograph glows orange from light pollution.
In Bow Of Orion Canada's Karl Johnston captures the Northern Lights. This glowing curtain of coloured sky is caused by a stream of particles from the Sun called Solar Wind which are pulled in by the Earth's poles.
The Republic of Ireland's Michael O'Connell has been selected for his picture Blue Sky Moon. Unusually the Moon is shown here during the day through a dark blue sky - giving it the appearance of rising mysteriously from shadow.
Horsehead Nebula is the work of the UK's Martin Pugh. The Horsehead Nebula is a dark cloud of gas; dust and other materials. These condense to form dense knots, which will eventually become stars and planets. New stars have already formed inside part of the dust cloud, as can be seen on the bottom left.
Another British entry is Comet Holmes. Nick Howes captured the nucleus of this "dirty snowball" made of ice, rock and frozen gases. Comet Holmes has an orbit between Mars and Jupiter and can be seen faintly about every seven years.
A new generation of stars are condensing in this picture of Eta Carina nebula by the USA's Thomas Davis. This vast cloud of dust and gas is estimated to be between 6,500 and 10,000 light years away.
Another of Briton Martin Pugh's entries is Galactic Dust in Corona Australis. Dominating the frame are two blue-reflection nebulae which scatter the light of nearby stars. A much older globular cluster of thousands of stars can be seen at the top right.
This picture, taken by Vincent Miu of Australia, was taken with a two-hour exposure. It shows the trails of Venus, Jupiter and the Moon rising into the sky at sunset.
All the stars seen in the foreground of this image are from our own Milky Way, with the Centaurus-A galaxy in the centre, millions of light years beyond. By Michael Sidonio, Australia.
This photograph is a 40-minute exposure of the trails made by the stars over Death Valley as the Earth rotates. Nikhil Shahi, USA.
