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’.
The solar corona can be seen during the solar eclipse on April 8. Astronomers are still trying to figure out the mysteries of the corona, including why it’s so hot.
The sun is expected to reach its solar maximum in 2025. Recent auroras suggest that the maximum may be bigger than predicted.
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 eruption was so large, it created its own space weather and satellite technology disruptions – here’s how.
The aurora is one of nature’s most spectacular sights, a dazzling glow in the upper atmosphere driven by space weather.
Space weather can affect satellites in a number of different ways, from frying electronics to increasing drag in the atmosphere.
A curious kid asks: Why are the northern lights only spotted at areas around the poles?
The CUAVA-1 cubesat will monitor space weather and changes to Earth’s ionosphere that affect satellites and electronics.
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.
Satellites, space stations and astronauts, aviation, GPS, power grids and more can be affected.
We observed a powerful flare and a huge burst of radio waves from our nearest stellar neighbour, Proxima Centauri, indicating violent space weather around the star.
Has the Sun entered a stage of old age?
The sun’s phenomena, like flares, can cause solar particles to enter the Earth’s atmosphere, with material effects.
Scientists spend years preparing for the two-minute window of a total solar eclipse.
The Lagrange mission could greatly improve forecasts of space weather.
When dozens of US mines planted in waters off the Vietnam coast detonated almost simultaneously in 1972, all eyes turned to the Sun for an explanation.
The Earth’s magnetic field lines whistle after solar outbursts.
The wired Earth of the 21st century is at the mercy of the volatile nature of the sun.
