ALT Rubin Observatory in a golden sunset, with silver dome glinting in the setting sun's light. We see the observatory's long white service building and vertical silver dome such that the white service building appears pointed slightly to our left. To the left, the brilliantly setting sun glows bright orange, illuminating the landscape in a golden glow. The Chilean desert mountain ridges become more and more opaque as they recede into the distance, creating a layered look.

ALT The process of taking Rubin’s first data with the Commissioning Camera began well before sunset, with the team readying the telescope, dome, and mirrors. They conducted twilight calibrations while the sky was still dimming, then pointed the telescope towards a bright star to confirm pointing and focus.
