The event horizon is a critical concept in astrophysics, particularly in the study of black holes. It refers to the boundary around a black hole beyond which nothing, not even light, can escape its gravitational pull. Once an object or light crosses the event horizon, it is said to be inside the black hole and can never return to the outside universe.

When astronauts return to the Moon they will be bringing along a new generation of spacesuits, designed to withstand the harsh conditions of the lunar surface. But in keeping their human occupants safe and comfortable, these suits might also become a fertile environment for harmful microbial life – especially as astronauts will potentially be sharing suits with one another.

The Hubble Space Telescope captured a new view of a spiral galaxy called UGC 12295, which is believed to have recently hosted a supernova, allowing astronomers to study the debris of the stellar explosion.
