Would astronauts' kidneys survive a roundtrip to Mars?

The structure and function of the kidneys is altered by space flight, with galactic radiation causing permanent damage that would jeopardize any mission to Mars, according to a new study led by researchers from UCL.

Researchers shed new light on solar flares

Plasma astrophysicists at KU Leuven have created the first self-consistent simulation of the physical processes that occur during a solar flare. The researchers used Flemish supercomputers and a new combination of physical ...

Eye-opening numbers on space debris

Orbital debris, otherwise known as "space junk", is a major concern. This massive cloud that orbits the Earth is the result of the many satellites, platforms and spent launchers that have been sent into space over the years. ...

A comet visiting from the most distant parts of our solar system is putting on a spectacular nighttime display. The comet C/2020 F3 NEOWISE made its once-in-a-lifetime close approach to the sun on July 3 and will cross outside ...

The radiation showstopper for Mars exploration

An astronaut on a mission to Mars could receive radiation doses up to 700 times higher than on our planet—a major showstopper for the safe exploration of our solar system. A team of European experts is working with ESA ...
