What moment in 2011 stands out in your mind? The space shuttle launching into space one final time? An earthquake and tsunami that, in a matter of minutes, devastated a country? A royal wedding destined to be talked about for decades? As we wrap up the year, Flickr has pulled together a Year in Photos 2011 Gallery that covers several of the moving, emotionally charged, and surprising images that captivated us this year. Some of these images were captured using the most sophisticated digital cameras to date, while others were taken using the latest smartphones. Regardless, each photo captures a moment perfectly. Of course, this wouldn't be possible without the help of our Flickr community, who helped us reach new heights in 2011, including more than 6 billion photos now stored on Flickr and more than 200 million images now available through our Creative Commons  service. Many thanks to all of the Flickr members who provided photos for this collection, and here's to 2012 and capturing even more memorable moments.
