A research team led by Imperial College London has presented in a new study that Coronal Mass Ejections (CMEs) or solar storms could be more extreme than previously believed when they "slipstream" each other or when two such events follow each other....

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...

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...

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...

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...

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 /...

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...

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...

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...

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...

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...

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....

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...
