Alfvén waves, first proposed 80 years ago, could explain why the sun’s atmosphere is so much hotter than its surface.
The interaction of solar winds and the Earth’s atmosphere produces the northern lights that dance across the night sky.
It has only been in the past century that weather prediction on Earth has advanced enough to work two weeks in advance. Predicting space weather, however, is only reliable an hour in advance.

The Earth’s magnetic field was most likely weaker when life evolved on our planet than it is today.
The Lagrange mission could greatly improve forecasts of space weather.

The Earth’s magnetic field has a beat, scientists discover.

A bright comet visible in December provides an excellent viewing opportunity for night sky lovers – even potentially with the naked eye.

Scientists still don’t know what caused the mysterious phenomenon ‘Steve’.
Mars is not great for sunbathing anymore.
The solar wind has stripped Mars of its atmosphere, making it a lot less habitable than it once was.
Comet 67P and its mysterious jets.

Rosetta has finally shed light on the origin of both ice and jets on comet 67P. It will now head closer to the sun to look at the comet’s interactions with the solar wind.
When the sun flares, space weather is on its way to Earth.
Our power grid infrastructure on Earth is more vulnerable to space weather than previously thought – with susceptibility in more regions and even during quiet geomagnetic periods.
Tempestuous times on the solar surface.
It’s the windiest place in the entire solar system – and these storms can be felt here on Earth.
Amazing colours in the Southern Lights seen from Primrose Sands, near Hobart.
Over the past few months night sky watchers in the southern parts of Australia have been presented with lots of beautiful displays of the Aurora Australis or Southern Lights. So what causes the impressive…
Energetic particles from the sun may contribute to the frequency and volume of lightning strikes, researchers from the University…
New source of water?
Water ice is the most abundant solid material in the universe. Much of it was created as the byproduct of star formation, but not all. John Bradley of Lawrence Livermore National Laboratory and his team…
