Europe readies for solar storm risks

Europe launched its first space weather coordination centre Wednesday to raise the alarm for possible satellite-sizzling solar storms that also threaten astronauts in orbit, plane passengers and electricity grids on Earth.

Ten things we've learned about the sun from NASA's SDO this decade

In February 2020, NASA's Solar Dynamics Observatory—SDO—is celebrating its 10th year in space. Over the past decade the spacecraft has kept a constant eye on the sun, studying how the sun creates solar activity and drives ...

Dazzled by the bright Southern Lights

The past week saw a fantastic treat for aurora watchers. Generally it is the southern part of the country, Tasmania in particular, that sees the most impressive displays. But this aurora has been so intense that it was even ...

Parker makes its closest and fastest solar flyby

The Parker Solar Probe is the little engine that just keeps going and going by the sun. On September 27th, it made its 17th close approach and skimmed just 7.26 million kilometers (4.51 million miles) above the sun's "surface" ...

Sun delivered curveball of powerful radiation at Earth

A potent follow-up solar flare, which occurred Friday (Jan. 17, 2012), just days after the Sun launched the biggest coronal mass ejection (CME) seen in nearly a decade, delivered a powerful radiation punch to Earth's magnetic ...

SOLIS observatory gives new insights into space weather

(Phys.org) —Shifts in the magnetic field just above the surface of the Sun lead to liftoff of interplanetary "space storms," according to new results from the Synoptic Optical Long-Term Investigation of the Sun (SOLIS) ...

This is what can happen when a CME hits Earth

This video taken by Göran Strand from Östersund, Sweden shows what happened on March 17, 2013 when a Coronal Mass Ejection hit Earth's magnetic field. Two days earlier, sunspot AR1692 had produced a M1-class solar flare ...

Researchers find clues to how hazardous space radiation begins

Scientists at the University of New Hampshire have unlocked one of the mysteries of how particles from flares on the sun accumulate at early stages in the energization of hazardous radiation that is harmful to astronauts, ...
