Scientists eager to examine images to research phenomenon known as lunar horizon glow, first documented in 1972

Nasa has released the first high-definition images of a sunset on the moon, two striking photographs taken by the private lander Blue Ghost that could offer scientists further clues to the mysterious phenomenon known as lunar horizon glow.

The agency presented the images to a press conference on Tuesday at Houston’s Johnson space center, marking the conclusion of a 14-day mission conducted in partnership with Texas company Firefly Aerospace.
