    This beautifully composed image of the Whirlpool Galaxy combines fine detail in the spiral arms with the faint tails of light that show its small companion galaxy being gradually torn apart by the gravity of its giant neighbour. A closer look shows even more distant galaxies visible in the background.

    The photographer came across two hikers lost in the wilderness of Yosemite late one evening in July 2011. He captured this image of the tiny figures in a small bubble of torchlight set within a vast, pitch black forest beneath the immense dome of the sky. It highlights the wonder, beauty and awe of astronomy.

    The photographer here set out to show not only the main subject of the image - a vast supernova remnant - but also the objects in the wide starscape that surrounds it. Straddling the constellations of Auriga and Taurus, Simeis 147 consists of the expanding debris of a massive star which exploded around 40,000 years ago. As the wreckage continues to spread out into space it collides violently with the dust and gas between the stars, sculpting it into the glowing shells and filaments which have earned Simeis 147 the nickname of the 'Spaghetti Nebula'

    Taken in Nagano, Japan, this image shows Orion, Taurus and the Pleiades as the backdrop to an eerie frozen landscape. Though the stars appear to gleam with a cold, frosty light, bright blue stars like the Pleiades can be as hot as 30,000 degrees Celsius.

    Earth and space are evenly weighted in this wonderfully framed image of a Californian landscape beneath the Milky Way. The young photographer has chosen a view of an ancient Bristlecone Pine which is over 4000 years' old, and whose sloping trunk and gnarled branches provide perfect counterpoint to the edge-on view of the starry disc and knotted structure of our galaxy.

    This photograph from the Young category of the competition skilfully frames the streaming, swirling patters of the Northern Lights with treetops below and a starry sky above. In the centre of the image, which was taken in the far North, close to the Arctic Circle, Orion the hunter is just visible through the bright auroral display. Taurus the bull and the bright Pleiades star cluster are seen in the clear area to the upper right.

    This skilled young astrophotographer has captured a beautifully sharp and artfully framed detail of the Moon. The terminator - which separates the daytime and night-time parts of the Moon - is aligned with the bottom edge of the photograph. The Sun's light shines at a low angle onto the surface of the Moon just above this line, showing the contrast between smooth maria (lunar 'seas') and rugged crater rims to the best advantage.

    This young photographer has knitted together several high resolution images of the Moon in the daytime sky to form a colourful mosaic. This wonderfully detailed view shows the smooth dark maria (lunar 'seas') and lighter, bumpier highlands of the Moon, both dotted with craters. The peaceful blue colour of the daytime sky is caused by scattering of blue light in the Earth's atmosphere.

    Among the nearest star clusters to Earth, the stars of the Pleiades (Messier 45) are easily seen with the naked eye in the Northern hemisphere's winter skies. While it is often called the Seven Sisters, this beautiful photograph reveals many more of the hot, young stars which comprise the cluster. The young photographer has also captured the swirling wisps of a diaphanous gas cloud through which the cluster is currently passing, lighting it with reflected starlight. It was taken near dusk, with two frames and an hour of exposure.

    A spiral system like the Milky Way, Messier 63 has arms which encircle the yellowish centre of the galaxy like the petals of a flower, earning it the nickname of the Sunflower Galaxy. This image was captured by the young photographer using the Bradford Robotic Telescope in Tenerife, which he controlled over the internet.

    The Elephant's Trunk seems to uncoil from the dusty nebula on the right of the image, its tip curled around a cavity carved out by the radiation produced by young stars. Capturing a deep sky object like this takes skill and painstaking attention to detail and is a great achievement for a newcomer to astrophotography.

    This picture was taken on the wet sand at low tide on the beach at Tr├ęguennec in North West France and shows the conjunction of Venus and Jupiter. One of the astronomical highlights of 2012, the conjunction was the period when the two bright planets appeared conspicuously close together in the sky. Their apparent closeness was an optical illusion - Jupiter was in fact millions of kilometres further away than Venus. The photographer is pictured in the lower right corner of the frame and the Pleiades and Taurus are also visible on the upper left.

    Perhaps the biggest astronomical event of 2012 was the transit of Venus, which took place in June. Transits occur when Venus passes directly between the Earth and the Sun, appearing as a small black disc passing across the face of our parent star. They occur in pairs, eight years apart, with each pair separated by over a century. The previous transit was in 2004 and the next will not be until December 2117. This is a spectacular view of the active Sun, streaked and blotched with filaments, sunspots and prominences. Venus, a world almost exactly the same size as the Earth, seems dwarfed by the scale and power of our local star.

    Comet Garradd was discovered in 2009 as it approached the inner Solar System. It became visible through binoculars in 2011 but has never been visible to the naked eye. To bring out the greenish glow of the comet's halo the photographer has used a long exposure. The star trails show how he has tracked the comet's orbital motion to keep it in the centre of the frame and the picture illustrates how the comet moved relative to the stars in 38 minutes

    This sequence of photographs, taken in March 2012, uses the rotation of Mars to build up a complete view of the planet's surface. It shows the gleaming north polar cap of frozen water and carbon dioxide, the red equatorial deserts and the darker southern highlands. The photographer has captured an amazing level of detail, including wispy clouds in the thin Martian atmosphere.

    Perhaps the biggest astronomical event of 2012 was the transit of Venus, which took place in June. Transits occur when Venus passes directly between the Earth and the Sun, appearing as a small black disc passing across the face of our parent star. The next transit will not take place for 105 years, in December 2117. This is a single unprocessed raw frame shot using a hydrogen-alpha (Ha) filter. It was captured early on the morning of 6 June between second and third contact, the photographer's first and only glimpse taken through a thin patch in the clouds at Blackheath in London. The image captures the excitement of the 2012 transit of Venus, and the delight of observers in the UK who managed to catch a fleeting view despite the British weather.

    Situated almost 250 million light-years away from us, The Perseus Cluster, also known as Abell 426, contains more than 500 catalogued galaxies. Some are spirals like the Milky Way while others are giant, smooth elliptical systems. Together they form one of the largest structures in the Universe. Each smudge of light in this photograph contains millions, if not billions, of stars.

    The spooky shapes that seem to haunt this starry expanse are in fact cosmic dust clouds that fill huge volumes of space between the stars. The dust consists of tiny grains of minerals and ices and is an important building block for the formation of future stars and planets. The photographer had to travel 1000 kilometres in to the mountains of the Crimea to find a sky dark enough to capture this image.

    Part of the Veil Nebula, the 'Witch's Broom' is the glowing debris from a supernova explosion - the violent death of a massive star. Although the supernova occurred several thousand years ago, the gaseous debris is still expanding outwards, producing this vast cloud-like structure. In this image narrowband filters have been used to greatly increase detail while giving a reasonable representation of the nebula's colour.

    The Milky Way arches over a mirror-like lake on the island of Reunion. At the bottom of the picture Piton des Neiges, the highest peak of Reunion Island, can be seen. The bright patch to the left of the image marks the bulge of stars at the heart of our Galaxy. The photographer waited two years before all the combined conditions were favourable to succeed with this photo.
