Moon glows brighter than sun in images from NASA's Fermi

If our eyes could see high-energy radiation called gamma rays, the Moon would appear brighter than the Sun! That's how NASA's Fermi Gamma-ray Space Telescope has seen our neighbor in space for the past decade.

Lunar and solar eclipses make animals do strange things

For most animals, the structure of their day—and indeed their year—depends on the light-dark cycle. These regular and rhythmic cycles in the length of days tell animals when they should be foraging, when they should be ...

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 ...

The space we travel through

When sea-faring nations began to explore new regions of the world, one of their biggest concerns in making the journey safely was how to cope with weather. They could harness the wind for power. They could rely on the Sun ...

New 3-D map will help solve long-standing cosmic mysteries

A new study led by ANU has created a 3D map of the magnetic field in a small wedge of the Milky Way galaxy, paving the way for future discoveries that will improve our understanding of the origin and evolution of the Universe.

Earth's magnetic poles could start to flip. What happens then?

As Earth's magnetic shield fails, so do its satellites. First, our communications satellites in the highest orbits go down. Next, astronauts in low-Earth orbit can no longer phone home. And finally, cosmic rays start to bombard ...

Scientists help solve mystery of why comets emit X-rays

The mystery of why comets travelling through Space give off X-ray emissions has been solved thanks to new research undertaken by a team that included science staff from STFC's Central Laser Facility (CLF) and RAL Space.

The occurrence of magnetism in the universe

Flows of molten metal can generate magnetic fields. This so-called dynamo effect creates cosmic magnetic fields, like those found on planets, moons and even asteroids. In the coming years, researchers are conducting a unique ...
