A pattern of #Humanfootprints found south of #LakeNatron in #Tanzania. The footprints are believed to be approximately 120,000 years old and made by some of our earliest ancestors. Fossilized footprints are an extremely rare find and can tell archeologists a great deal about the humans that made them including their size, stride and bipedal abilities. This image was shot on a story for @natgeo alongside the Curator of Human Origins at the American Museum of Natural History, #Amnh #BrianRichmond. The information gained from this find proved to be invaluable to our current understanding of the #evolution of the human #species and how we came to be. @robertclarkphoto @thephotosociety

On the night of Oct. 8, a photographer in Harstad, Norway captured this image of the dancing northern lights. Auroras are created when fast-moving, magnetic solar material strikes Earth's magnetic bubble, the magnetosphere. This collision rattles the magnetosphere in an event called a geomagnetic storm, sending trapped charged particles zooming down magnetic field lines towards the atmosphere, where they collide brilliantly with molecules in the air, creating auroras. Though many geomagnetic storms are associated with clouds of solar material that explode from the sun in an event called a coronal mass ejection, or CME, this storm was caused by an especially fast stream of solar wind. "Geomagnetic storms caused by high-speed solar wind streams aren't uncommon," said Leila Mays, a space physicist at our Goddard Space Flight Center in Greenbelt, Maryland. "Near solar minimum-when solar activity like CMEs are less frequent-these fast streams are actually the most common cause of geomagnetic storms that create auroras."
