Timelapse footage of the WIYN 3.5-meter Telescope at night.

This timelapse footage of the WIYN 3.5-meter Telescope at the Kitt Peak National Observatory (KPNO), a Program of NSF's NOIRLab. As Earth rotates the stars appear to travel west across the night sky over the Tohono O'odham Nation Reservation where KPNO is located. The observing dome periodically rotates to allow the telescope to track its target object as it moves throughout the night. The Wisconsin-Indiana-Yale-NOIRLab (WIYN) Observatory is a partnership consisting of Indiana University, University of Wisconsin-Madison, Pennsylvania State University, Princeton University, Purdue University, NSF’s NOIRLab, and NASA. This partnership between public and private universities and NOAO was the first of its kind. The telescope hosts the NEID instrument, which is a state-of-the-art exoplanet-discovery machine.
