Astronomers probing the edges of the Milky Way have in recent years observed some of the most brilliant pyrotechnic displays in the galaxy: superflares.

A new, first-of-its-kind space weather model reliably predicts space storms of high-energy particles that are harmful to many satellites and spacecraft orbiting in the Earth's outer radiation belt.

Three mathematicians and a physicist from the Universitat Autònoma de Barcelona (UAB), the Mathematics Research Centre (CRM) and the Barcelona Graduate School of Mathematics (BGSMath) propose a mathematical model which allows making reliable estimations on the probability of geomagnetic storms caused by solar activity.

Queen Mary University of London has led a study which describes the first direct measurement of how energy is transferred from the chaotic electromagnetic fields in space to the particles that make up the solar wind, leading to the heating of interplanetary space.

The Science Of Space Weather

Space weather is no abstract concept - it may happen in space, but its effects on Earth can be significant.

Historic space weather may help us understand what's coming next, according to new research by the University of Warwick.

Earth is constantly being hammered by charged particles emitted by the Sun that have enough power to make life on Earth almost impossible.

An unlucky coincidence of space and Earth weather in early September 2017 caused radio blackouts for hours during critical hurricane emergency response efforts, according to a new study in Space Weather, a journal of the American Geophysical Union.

A team of researchers, supported under ESA's Basic Activities, has recently investigated a resourceful new method of monitoring space weather.

The True Power Of The Solar Wind

Electrically charged particles from the sun strike moons and planets with great force. The consequences of these impacts can now be explained by scientists from TU Wien

Last September, a massive new region of magnetic field erupted on the Sun's surface next to an existing sunspot.

Measurements of the three-dimensional structure of the earth, as opposed to the one-dimensional models typically used, can help scientists more accurately determine which areas of the United States are most vulnerable to blackouts during hazardous geomagnetic storms.

A dramatic magnetic power struggle at the Sun's surface lies at the heart of solar eruptions, new research using NASA data shows.

NASA rockets launched during the Alaskan winter typically explore the interaction of solar winds with Earth's atmosphere and the resulting auroras that dance across the night sky.

When our Sun erupts with giant explosions -- such as bursts of radiation called solar flares -- we know they can affect space throughout the solar system as well as near Earth.

Solar Wind May Affect Satellite Safety

Could the flapping of a butterfly's wings in Costa Rica set off a hurricane in California?

The space surrounding our planet is full of restless charged particles and roiling electric and magnetic fields, which create waves around Earth.

Our Cold War history is now offering scientists a chance to better understand the complex space system that surrounds us. Space weather.

Our ever-changing sun continuously shoots solar material into space. The grandest such events are massive clouds that erupt from the sun, called coronal mass ejections, or CMEs.

NASA has long been a leader in understanding the science of space weather, including research into the potential for induced electrical currents to disrupt our power systems.
