Solar storm stirs stunning aurora

After the sun ejected a violent mass of fast-moving plasma into space on 9 October, ESA waited for the storm to strike. A few days later, the coronal mass ejection (CME) arrived at Earth, crashing into our planet's magnetosphere, ...

New sunspot catalogue to improve space weather predictions

Scientists from the University of Graz, Kanzelhöhe Observatory, Skoltech, and the World Data Center SILSO at the Royal Observatory of Belgium, have presented the Catalog of Hemispheric sunspot Numbers. It will enable more ...

Significant solar flare erupts from sun

The sun emitted a significant solar flare peaking at 10:29 a.m. EDT on July 3, 2021. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event.

Which way does the solar wind blow?

The surface of the sun churns with energy and frequently ejects masses of highly-magnetized plasma towards Earth. Sometimes these ejections are strong enough to crash through the magnetosphere—the natural magnetic shield ...

Moon mission delays could increase risks from solar storms

Planned missions to return humans to the Moon need to hurry up to avoid hitting one of the busiest periods for extreme space weather, according to scientists conducting the most in-depth ever look at solar storm timing.

Water mission takes on space weather

For well over a decade, ESA's SMOS satellite has been delivering a wealth of data to map moisture in soil and salt in the surface waters of the oceans for a better understanding of the processes driving the water cycle. While ...
