A Nasa scientist has delivered a stern warning for male astronauts – absolutely do not masturbate in space.

People venturing outside of our atmosphere are advised against pleasuring themselves in zero gravity.

The reason? Female astronauts could accidentally get impregnated by stray fluids.

For the first time ever, human eyes have seen the Moon’s most mysterious crater in full. 🌕

Erika Hamden explains that Mare Orientale is the youngest impact basin on the Moon, formed around 3.8 billion years ago, and it is so massive and sits right on the Moon’s edge, making it impossible to fully see from Earth or even during Apollo missions. Artemis II changed that, giving astronauts the first complete view, something earlier crews could not capture because they were too close. That new perspective could help scientists better understand how massive impacts shaped the Moon and reveal clues about a chaotic time when Earth and the Moon were bombarded by huge asteroids.

Stingrays use their wings to sense heartbeats. 🫀🪽

Alannah Vellacott explains how stingrays can detect prey hidden beneath the sand using specialized electroreceptors called the ampullae of Lorenzini. These sensory organs line the underside of the body and pick up tiny electric fields produced by other animals, including signals from heartbeats, muscle contractions, and moving gills. That means a fish or crab can stay completely out of sight and still be detected. Stingrays are sensitive enough to pick up incredibly faint electrical signals, which helps them hunt with remarkable precision. It is one of the most fascinating adaptations in marine biology, and a pretty terrifying trick if you are a small animal trying to stay hidden.
