A new study published in the Nature Scientific Reports on July 13 suggests that powerful eruptions on the Sun can trigger large earthquakes on Earth. In the paper, the authors analyzed 20 years of proton density and velocity data, as recorded by the SOHO satellite,…
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…
The Sun's magnetic activity fluctuates in a rhythm of about 11 years, which is reflected in the frequency of sunspots. During solar maximum, huge sunspots and active regions appear on the surface of the star. Scientists have long been puzzled over the reason…
Scientists at the Skolkovo Institute of Science and Technology in Russia along with colleagues from the Karl-Franzens University of Graz and the Kanzelhoehe Observatory, Austria have formulated a new automatic method for tracking coronal dimmings or traces of…
In a new study, physicists from the University of Wisconsin-Madison help explain why the solar wind's temperature becomes 10 times larger than expected when it reaches the Earth. Previously, researchers thought the solar wind has to cool down very rapidly as it…
An increasing amount of research indicates that solar storms can be even more powerful than measurements have shown so far via direct observations. Researchers believe that society is not sufficiently prepared if a similar event were to happen now. The researchers…
Japanese researchers have taken the first steps to understand how the Sun's rotational cycle influences lightning activity on Earth. The answers were found in diaries dating back to the 1700s. "It is well known that long-term – centennial to…
A new measurement and modelling tool/technique, developed by Dr Neel Savani of Imperial College London and NASA's Goddard Space Flight Center, could give more than 24 hours' notice of large magnetic storms from the Sun that could be harmful to systems on…
A team of researchers at NASA's Johnson Space Center in Houston and Lawrence Berkeley National Laboratory in Berkeley, Calif., has found radiation from protons could further enhance a process that occurs during tumor progression. This information may help lead…
