A lava faucet in Hawaii, a bat-like robot, and other amazing images of the week

The United States Geological Society captured gorgeous images of the'lava faucet' currently spewing out of Hawaii's Kilauea volcano. It's been erupting since 1983, but on New Year's day, the lava caused a rock structure to collapse, exposing the flowing lava. Researchers are now concerned that the surrounding cliff might collapse as well, making the area even more dangerous than it already is.
