New observations of coronal mass ejections and cosmic rays

New observations of coronal mass ejections and cosmic rays

Scientists have released new observations of solar activities, such as Coronal Mass Ejections (CMEs) and cosmic rays, gathered by the Global Muon Detector Network (GMDN) at the Syowa Station in the Antarctic. The team found that high-speed solar wind causes the…

New project for more accurate space weather predictions

New project for more accurate space weather predictions

Professor Clare Watt, a space plasma physicist from Northumbria's Department of Mathematics, Physics and Electrical Engineering, is leading a new project that aims to forecast space weather more accurately. Funded by the Science and Technology Facilities Council…

Researchers propose new formation mechanism for solar coronal rain

Researchers propose new formation mechanism for solar coronal rain

Coronal rain is a phenomenon on the Sun that plays a key role in the mass cycle between the hot corona and cool chromosphere. In a new study, a team of researchers has proposed a new formation mechanism for coronal rain along open magnetic structures, showing that…

Researchers investigate what happens if ‘perfect solar storm’ hits Earth

Researchers investigate what happens if ‘perfect solar storm’ hits Earth

In a new study published in Space Weather journal, researchers investigated what might happen if a 'perfect' coronal mass ejection (CME) hit the Earth. Using state‐of‐the‐art computer models to simulate the worst-case solar storm, the team found that…

Researchers reconstruct 11-year solar cycles all the way back to year 969

Researchers reconstruct 11-year solar cycles all the way back to year 969

An international team of researchers reconstructed the Sun's 11-year cycles all the way back to year 969 using measurements of radioactive carbon in tree rings. The findings help scientists better understand the dynamics of the Sun, enabling more accurate dating…

New method helps predict big solar flares

New method helps predict big solar flares

Scientists developed a new physics-based technique that successfully predicted seven of the Sun's largest flares from the past solar cycle, out of a set of nine. With further improvement, the new model could be used to inform forecasters of these intense…

New phenomena discovered on the Sun

New phenomena discovered on the Sun

A new Sun-observing mission led by ESA and NASA — Solar Orbiter — has returned its first images of the Sun, revealing previously unknown omnipresent miniature solar flares, dubbed 'campfires.' The campfires shown in the image below were captured by the…

Scientists measure structure of enormous solar flare

Scientists measure structure of enormous solar flare

Astronomers at the Harvard-Smithsonian Center for Astrophysics reported spatially-resolved observations of the regions of the Sun's magnetic field and flare-ejected electron activity, with the results suggesting that these kinds of spatial structures in the…
