Understanding how natural hazards impact our upper atmosphere and cause variations in the space environment

A new study shows that natural hazards on Earth, specifically earthquakes and tsunamis, can create much more disturbances in the ionosphere than previously assumed. The researchers studied the catastrophic 2011 M9.0 Tohoku earthquake and tsunami in Japan, and found...

Using artificial intelligence to provide space weather alerts in real-time

A new study suggests that computers can learn to detect solar flares and other occurrences in vast streams of solar images, helping NOAA forecasters issue space weather alerts more in real-time. The machine-learning technique was improved by scientists at CIRES and...

Plasma space tornadoes let high-energy particles into near-Earth space

Researchers using NASA's Magnetospheric Multiscale mission (MMS) discovered tornado-like swirls of plasma create a magnetosphere tumultuous enough to let harmful high-energy particles from the Sun slip into near-Earth space. The discovery is important for...

NASA detects solar flare pulses at Sun and Earth

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. But monitoring their effects requires having observatories in many places with many...

A new approach to forecasting solar flares

The emerging discipline of space meteorology aims to reliably predict solar flares so that we may better guard against their effects. Using 3D numerical models1, an international team headed by Etienne Pariat, a researcher at LESIA (Observatoire de Paris / CNRS /...

Model explains the formation of Stealth CMEs

An international team of scientists has developed a model that simulates the evolution of Stealth CMEs, solar storms that puzzled scientists for their lack of typical warning signs as they seem to come from nowhere. Such computer models can help researchers better...

New insights into how eruptions occur on the Sun

Scientists have gained new insights into how eruptions occur on the Sun and, through 3-D computer simulation, identified a universal process that explains eruptions of every size, from tapered jets to massive explosions of solar material and energy. In a new study...

Discovery offers a way to predict solar flares

A new study led by a scientist at the National Center for Atmospheric Research (NCAR) has found that the same kind of large-scale planetary waves that meander through Earth's atmosphere driving our weather may also exist on our star and drive space weather. The...

K-Cor promises earlier space weather warnings

A new research instrument located on the Mauna Loa volcano in Hawaii - K-Coronagraph - showed the technique it uses to observe Sun's corona can be used to provide earlier warnings to astronauts when dangerous high-energy particles are blasted out of the...

EEGGL - New space weather model available to the public

A team at the University of Michigan has developed a new space weather model called EEGGL, short for the Eruptive Event Generator (Gibson and Low), in an effort to help researchers better understand how the Sun will affect near-Earth space, and potentially improve...

Origins of solar wind revealed

The origins of the constant flow of charged particles from the Sun, known as the solar wind, and the details of the transition from defined rays in the Sun's upper atmosphere to the solar wind have been a mystery ever since the discovery of solar wind in 1950s....

Robust CME simulation model developed for future of space weather forecasting

Japanese scientists have developed a new and robust simulation code for Coronal Mass Ejection (CME) events based on the realistic description of the mechanisms behind their generation and propagation through space. The method has been successfully validated using...
