In 1998, astrophysicists discovered a baffling phenomenon: the Universe is expanding at an ever-faster rate. Either an enigmatic force called dark energy is to blame or a reworking of gravitational theory is in order. In this new Science Bulletins video, watch a FermiLab team assemble the Dark Energy Camera, a device that could finally solve this space-stretching mystery.

Science Bulletins is a production of the National Center for Science Literacy, Education, and Technology (NCSLET), part of the Department of Education at the American Museum of Natural History. Each Bulletin is produced by AMNH's curatorial and scientific staff and a team of video producers, designers, writers, and educators using state-of-the-art technologies such as high-definition video and 3-D computer graphics to present the latest research.
