The 570-megapixel Dark Energy Camera, built at DOE's Fermilab and mounted on the 4-meter Victor Blanco Telescope in Chile, delivers some of the most detailed images of celestial objects. While about a third of the camera's observing time goes to scientists working on the Dark Energy Survey, dozens of other teams share the remaining time. While the majority of them focus on observing objects far away, five groups recently highlighted in Symmetry magazine are investigating things close to Earth, looking for "space junk" that could damage satellites, large rocks that could hit Earth and other objects traversing our solar system.
