NASA's Artemis II crew has photographed a remarkable 'Earthset' — the Earth appearing to set below the lunar horizon — during their mission around the Moon. The images, shared on social media by astronaut Reid Wiseman, show our planet as a vivid blue orb sinking against the stark grey lunar surface. The striking visuals mark a significant milestone for the Artemis programme (NASA's effort to return humans to the Moon for the first time since the Apollo era), offering a powerful reminder of Earth's fragility as seen from deep space.
