Sometimes a photograph can appear to be straight out of a dream. This month's collection of my favorite Photo of the Day images has many surreal moments—a fledgling astronaut, a gliding manta ray, and a fragile rope bridge across a giant expanse, to name a few. Whether you've seen these places before or not, there's always something new to be seen or experienced. Our planet deserves a second glance.
Janna Dotschkal is the editor of Photo of the Day, a curated look at photography from around National Geographic, including the magazine and our photo community, Your Shot. Liane DiStefano writes the captions and titles.
