Sunset behind Vera C. Rubin Observatory at Cerro Pachón in February 2024.

Rays of the setting sun appear to emanate from Vera C. Rubin Observatory atop its desert mountain summit. The clear sky takes up 75% of the image, and light rays from the setting sun radiate from the center horizon like spokes on a wheel. The boot-shaped observatory, with long white service building pointing left and angular silver dome sticking up, sits atop a shadowed summit on the right. Lower altitude mountain ridges recede into the distance.
