Earth-directed CME lights the skies

Earth experienced a geomagnetic storm on June 22, 2015 due to the arrival of an Earth-directed coronal mass ejection, or CME, from June 20.

Combining observations to better visualize a superflare

A team of Japanese astronomers used simultaneous ground-based and space-based observations to capture a more complete picture of a superflare on a star. The observed flare started with a very massive, high-velocity prominence ...

Suomi NPP satellite sees auroras over North America

(Phys.org)—Overnight on October 4-5, 2012, a mass of energetic particles from the atmosphere of the Sun were flung out into space, a phenomenon known as a coronal mass ejection. Three days later, the storm from the Sun ...

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.

SMOS and Swarm team up to spot huge solar storm

The sun erupted over the weekend, flinging electromagnetic radiation towards Earth, even illuminating skies with spectacular aurora borealis. For the first time, ESA's unlikely space weather duo of SMOS and Swarm tracked ...

Nanodust particles in the interplanetary medium

Dust particles smaller than about a wavelength of light are abundant in our solar system, created by collisions between asteroids and from the evaporation of comets. As they scatter sunlight, these particles produce the zodiacal ...

NASA spacecraft observe a Thanksgiving CME

(Phys.org)—On Nov. 21, 2012, at 11:24 a.m. EST, the sun erupted with an Earth-directed coronal mass ejection or CME. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory ...

First-of-its-kind NASA space-weather project

A NASA scientist is launching a one-to-two-year pilot project this summer that takes advantage of U.S. high-voltage power transmission lines to measure a phenomenon that has caused widespread power outages in the past.

ESA's solar eclipse maker, Proba-3

Hundreds of millions of people will witness next week's total solar eclipse across North America, and solar physicists from around the globe are flocking to join them. Eclipses offer a brief glimpse of the sun's ghostly surrounding ...
