A drone captures a sweeping view of the NSF-DOE Vera C. Rubin Observatory at sunset in 2024, perched atop Cerro Pachón in Chile. The observatory is preparing to begin a 10-year survey of the southern sky, taking a new image every 30 seconds and collecting around 2,000 images every three nights. This ambitious effort will create an unprecedented 3D time-lapse of the universe.

Press Release

SLAC-built world’s largest digital camera brings the night sky to life like never before.

This image combines 678 separate images taken by NSF–DOE Vera C. Rubin Observatory in just over seven hours of observing time. Combining many images in this way clearly reveals otherwise faint or invisible details, such as the clouds of gas and dust that comprise the Trifid nebula (top) and the Lagoon nebula, which are several thousand light-years away from Earth
