The Artemis II astronauts are on a course back to Earth after flying by the moon Monday, witnessing a solar eclipse, and breaking a distance record set by NASA's Apollo 13 astronauts.

The first humans to travel around the moon in more than 50 years experience hours of scientific wonder — and moments of deep emotion.

A floating Nutella jar aboard NASA's Artemis II went viral, with internet users calling the zero-gravity moment the greatest free advertisement in history.

President Trump praised the crew of NASA's Artemis II mission in a brief chat late Monday, saying they had "inspired the entire world" after they looped around the moon in a record-breaking voyage.

Besides photographing the scenes with high-powered Nikon cameras, the astronauts also pulled out their iPhones for some impromptu shots.

“The dark side of the moon”: The term has a poetic ring. It has long been mined in popular culture, not least by Pink Floyd, the English band whose so-named top-selling semi-psychedelic rock album cemented the term in the 1970s.

The moon looks to most amateur photographers like a bright detail on a completely dark background, and it appears to be about half the width if one fingernail on an outstretched hand. That makes it tricky to shoot with an iPhone, as anyone who has ever tried it can attest.
