This Month in Photo of the Day: Nature "We're farm people," says Janice Haney of Greensburg, Kansas. "I enjoy hanging clothes out. We don't have to waste electricity on the dryer.

This Month in Photo of the Day: Nature After a safari in the Masai Mara Park we were racing back to our camp trying to get home before sunset. No one is allowed out in the park after dark. When I saw this photo op I had to convince our driver to stop just for a second so I could take this one picture. It was worth the risk of a fine for being out after sunset but fortunately we made it back in time. This photo and caption were submitted to the 2008 International Photo Contest.

This Month in Photo of the Day: Nature Some green roofs can be far simpler to create than traditional roof gardens. Volunteers from Cook + Fox installed the New York City architectural firm’s roof themselves using Green Paks.

See more photographs from the May 2009 feature story "Green Roofs."

This Month in Photo of the Day: Nature When you swim with humpback whales it's not their size that overwhelms you but their beauty. You want to stay in that moment forever. These three humpbacks came over to me to check me out. They put on a beautiful dancing display that makes your heart stop and you wish for the moment to never end. When they were done ten minutes later they took off but left me with amazing memories. Tahiti, French Polynesia. This photo and caption were submitted to the 2008 International Photo Contest.

This Month in Photo of the Day: Nature This is the result of a ten-second exposure on a breezy evening from a suspension bridge in Upper Michigan's Porcupine Mountains.

At the end of it all, it was very, very satisfying and yes, ten seconds—often a minuscule amount of time in our daily standards—did feel like eternity.
