Australians were in for a Mother’s Day treat as auroras swept the skies. But there was little warning, and the spectacle didn’t repeat.
The electric rainbow of the aurora happens when excited atoms relax via ‘forbidden transitions’.
We’re currently a few years into the 25th studied solar cycle. An 11-year period of sun activity, this solar cycle is more active than previously expected.
The aurora is one of nature’s most spectacular sights, a dazzling glow in the upper atmosphere driven by space weather.
People expect to brave brutally cold landscapes if they want to catch sight of the aurora borealis. So people were stunned to see the ethereal light display as far south as Cornwall.
Space weather can affect satellites in a number of different ways, from frying electronics to increasing drag in the atmosphere.
It’s often said that the aurora, or the northern lights, is caused by ‘particles from the Sun’. But in reality things are more complicated.
A curious kid asks: Why are the northern lights only spotted at areas around the poles?
Depending on who you ask, the northern lights may, very occasionally, sound like ‘rustling silk’ or ‘two planks meeting flat ways’.
When solar particles reach the Earth, they not only produce spectacular auroras but also contribute to the chemical reactions leading to ozone depletion, which in turn influences climate patterns.
The northern lights might look like magic, but they can actually be explained by science – here’s how.
The wired Earth of the 21st century is at the mercy of the volatile nature of the sun.
At a time in the sun’s cycle when space weather experts expect less solar activity, our star is going bonkers with solar flares and coronal mass ejections. What effects will Earth feel?
Scientists still don’t know what caused the mysterious phenomenon ‘Steve’.
Historical records can help us understand what will happen to the northern lights.
Here’s how to tell airglow from northern lights.
New research solves enigma of strange hotspots in Jupiter’s atmosphere.
Recent Martian findings are just the latest discoveries of aurora on other planets, both in and out of our solar system.
Geomagnetic storms can interact with particles near Earth, causing issues for satellites and other tech. Researchers send balloons 20 miles into the sky to figure out just what’s going on up there.
