Adam Mann of Wired has put together this incredible gallery of astronomy photos picked by the Royal Observatory, with some of the images including "colliding galaxies, open star clusters, and frozen waterfalls beneath a twinkling night sky."
The competition is in its fourth year and growing, with a record 800 entrants submitting their cosmic photography. Winners were announced on Sept. 19 in four main categories -- Deep Space, Our Solar System, Earth and Space, and Young Astronomy Photographer of the Year -- and three special awards were also handed out.
The overall number one prize and top spot for the Deep Space category went to Martin Pugh for his amazing shot (above) of the Whirlpool Galaxy, which shows two galaxies colliding. Pugh also won in 2009 for his picture of the Horsehead nebula.
