Spotlight on Saturn's Aurorae
from Planetary

A UK team of researchers have discovered a secondary aurora sparkling on Saturn and also started to unravel the mechanisms that drive the process. Their results show that Saturn’s secondary aurora is much more like Jupiter’s in origin than it is the Earth’s.

Seeing the northern lights from Britain
from Magnetosphere

A chance glimpse of the northern lights from your back garden is unlikely without some preparation, particularly if you live in Britain. This is where auroral prediction services such as Lancaster University’s AuroraWatch are useful.

Many measurements are required to study the magnetsphere

When is the magnetosphere like an elephant?
from Magnetosphere

The magnetosphere is so vast, it cannot be entirely measured in exact detail. Observations are gathered using a suite of different instruments located onboard spacecraft, or arranged in networks across the surface of the Earth. Rather like in the Article Posted: 07-04-2008


Locations on the Sun's disk where new spots were seen to emerge: on the right in these plots, the West of the Sun, many new spots are missing as they are invisible.

Invisible spots on the Sun
from Solar Exterior

Sunspots appear dark because of their low temperature compared to the surrounding regions. The Sun is constantly producing new spots, and their identification and tracking is essential for predicting ‘Space Weather.’ But a team of UK scientists have discovered a surprising proble...

The Sun's hot secrets
from Solar Exterior

With the invention of the telescope at the beginning of the seventeenth century, Galileo discovered Saturn’s rings, sunspots on the sun, and craters on the moon. Today, advances in technology are still crucial to the discovery process. Advanced telescopes onboard the Japanese sat...

Researchers at the University of St Andrews have developed a more detailed computer model of the Sun's magnetic field than previously possible.

Modelling the Sun's explosive corona
from Solar Exterior

The sun's atmosphere is a violent, chaotic place, threaded with ropes of twisted magnetic field that build up stress and cause vast explosions more powerful than any man-made bomb. Direct measurements of the magnetic field are impossible, so scientists resort to complex computer ...
