- Groups of sunspots forewarn of gigantic solar storms that can unleash a billion times more energy than an atomic bomb. Fears that these giant solar eruptions could create havoc on Earth, and disputes over the sun’s role in climate change, are adding urgency to these studies.

Solar cycles have a huge impact on the Solar System but are relatively poorly understood. Scientists have ascertained that they seem inextricably linked with the solar magnetic field, which arcs across the surface of our Sun in twists, swirls, and loops. Roughly every 11 years, the Sun's magnetic poles flip, north becoming south and vice versa. Thi...
It's important to understand that we don't really have a good idea about what happens insidethe Sun. It is thought that the solar magnetic field is generated by a dynamo inside the star, a rotating, convecting, and electrically conducting fluid that converts kinetic energy into magnetic energy, spinning a magnetic field out into space around the Su...
Based on the findings of the 'interference pattern', McIntosh and his team have arrived at predictions of the current solar cycle that are more in line with current observations than official predictions – the ones based on sunspot counts. Solar cycle predictions, plotted against observations. (C. Möstl, helioforecast.space/solarcycle) However, it'...
Feb 7, 2023 · This past week, a part of the sun’s surface broke off and started circling the sun’s north pole almost as if it were a giant polar vortex––and scientists don’t know why.
Feb 15, 2023 · A part of the sun has broken off and was swept up in a polar vortex. Scientists say it's not as dangerous as it sounds.
Apr 3, 2023 · The amount of radiation emitted by the sun can be extremely dangerous for astronauts going beyond the protection of Earth's ionosphere - where the planet's atmosphere meets space.
