NASA astronaut and Artemis II mission commander Reid Wiseman and an astrophotographer have teamed up to create stunning, hypersaturated color images of the moon. The photographs reveal never-before-seen details of its surface. When NASA’s Artemis II crew made their historic flyby around the farside of the moon in April, they saw from their capsule windows the gray and pocked lunar surface. One of the mission’s objectives was to capture ample photographic data, and throughout and after the spaceflight, NASA released unprecendented views of the moon. Now the image team at the space agency is still sorting through and processing the tens of thousands of images captured during the mission. Many of them are incredible, but they are all a bit gray.

NASA has fired up the Cold Atom Laboratory aboard the ISS once again. This allows scientists to study the so-called 'fifth state of matter' for longer periods and with greater precision. The experiments are expected to provide new insights into nature while accelerating quantum technology for spacef...
