CAPE CANAVERAL, Fla. (AP) — A private lunar lander has captured the first high-definition sunset pictures from the moon. Firefly Aerospace and NASA released the stunning photos Tuesday, taken before the Blue Ghost lander fell silent over the weekend. One shot included Venus in the distance.

The images reveal a phenomenon known as "lunar horizon glow," which is believed to be caused by charged lunar dust particles levitating due to solar radiation. This glow was first emerged in theory by Apollo 17 astronaut Eugene Cernan and is now being studied in detail thanks to the Blue Ghost.

Firefly Aerospace on Monday announced the conclusion of its Blue Ghost lunar lander mission, declaring it the first “fully successful” commercial operation on the moon.
