Photos released Wednesday focus on the even smaller space rock Bennu. The 3D images taken by NASA's Osiris-Rex spacecraft , flying alongside Bennu, show a jagged boulder that's 170 feet (52 meters) across.
A real-life rocker helped create these stereo images: Queen's lead guitarist Brian May. May, who's also an astrophysicist, joined the science team in January. He also is collaborating on NASA's New Horizons spacecraft, which flew past the most distant object ever explored, Ultima Thule, on New Year's Day.
