Solar physicists say they have found a key source of intense gamma rays unleashed when Earth's nearest star produces its most ...

Our planet was rocked by some of the worst geomagnetic storms in more than 20 years. Triggered by a slew of solar flares, the ...

Space weather forecasting is a guessing game. Predictions of outbursts from the sun are typically based on the amount of activity observed on the sun’s roiling surface, without accounting for the ...

Scientists have detected a strange new type of high-frequency wave on the sun's surface, and the waves are moving three times faster than scientists thought was possible. The acoustic waves, called ...

The outer layers of the sun’s atmosphere are a blistering million degrees hotter than its surface. The hidden culprit? Magnetic activity. How Scientists Are Tackling the Tricky Task of Solar Cycle ...

Researchers have achieved a breakthrough in solar physics by providing the first direct evidence of small-scale torsional Alfvén waves in the sun's corona—elusive magnetic waves that scientists have ...

The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our ...

Star burst: a solar flare as seen by NASA's Solar Dynamics Observatory. (Courtesy: NASA/SDO) An intense blast of high-energy protons from the Sun pummelled the Earth in about 660 BC and left a ...

At its current solar maximum, our Sun has been pretty busy of late, flinging parts of itself at Earth and raising concerns about effects on satellites and power grids while also gracing us with ...

New evidence that solar neutrinos can change “flavour” confirms that our understanding of the Sun is correct and that neutrinos have mass. Massive attack: data from the SNO experiment and elsewhere ...

Groundbreaking advances in solar and space physics have provided key insights into the inner workings of the heliosphere, the vast protective bubble formed by the solar wind that extends from the Sun ...

Solar physics investigates the complex processes occurring in our Sun – the nearest star and a prototypical example of stellar activity. Central to the discipline is an understanding of the Sun’s ...
