The competition has received more pictures than ever before. This striking photograph shows the Milky Way arching over Yosemite Valley in the United States. It was taken by Rogelio Bernal Andreo.
This one was taken in Norway and shows an astrophotographer at work! Often photographers camp out in remote locations away from the bright lights of towns and cities to get the perfect shot. The photo is by Tommy Eliassen.
The bright light in the sky of this photo is the Moon, reflecting light from the setting Sun. Can you spot the dust and gas tail of Comet Panstarrs on the horizon? It was snapped by Ingolfur Bjargmundsson.
Do you remember Newsround's report about Venus passing in front of the Sun? It only happens twice in a century - but was captured by photographer Alexadru Conu.
This photo by Wayne England was taken in Australia. It shows the Milky Way appear to line up with the dish of a radio telescope.
The photo by James Woodend is called 'Photographers on the Rim of Myvatn Craters'. They were lucky to capture this majestic scene whilst on their photography trip.
This photo is called 'Eta Carinae and her Keyhole' and was taken by Michael Sidonio. The Carina Nebula is a region several thousand light years from Earth where new stars are being formed.
Check out these amazing space snaps which have been entered into the 2013 Astronomy Photographer of the Year competition. This photo shots the Milky Way above the rocks of Durdle Door in Dorset. It was taken by photographer Stephen Banks.
This one is by Andre van der Hoeven and is called 'Herbig-Haro Objects in the Pelican Nebula'.
Check out the bright orange moon in this photo by Stefano De Rosa. It appears orange because the white light of the Sun is scattered by the Earth's atmosphere.
The clouds in the sky of this snap are called noctilucent clouds. They are formed of tiny ice crystals high in the atmosphere and they only become visible during twilight. The photo was taken by Mark Shaw.
This shot shows the shimmering Northern Lights and was taken by Mike Curry. All the photos in the competition will be judged by a panel of experts, including friend of Newsround Dr Maggie Aderin-Pocock! The winners will be announced on 18 September.

This snap was taken in Dartmoor National Park in the south-west of England. The brightest star in the sky is Sirius. It was taken by Anna Walls.
This photo is of the Orion Nebula. Modern cameras can detect light that's too faint for our eyes to see and are able to distinguish levels of detail well beyond our own capabilities. It was taken by Nik Szymanek.
