Images captured by NASA's Solar Dynamics Observatory have revealed that "coronal loops" give off subtle flashes of ...

As sunspots emerge on the sun's surface close to its equator, their orientations will match the old magnetic field, while sunspots forming closer to the poles will have a magnetic field matching the ...

No matter where it came from, the sunspot could pose a problem for Earth. That’s because it’s massive size could lead to dangerous M-class solar flares. These bursts of high-energy radiation ...

NASA/Solar Dynamics Observatory Solar flares are sudden ... in regions of the sun with strong magnetic fields, usually near sunspots and are more frequent during the solar maximum, when the ...

Flickering coronal "loops" on the Sun are warning signs of a coming solar eruption, paving the way for better space weather ...

For example, in August, the number of visible sunspots on our home star, which is a key metric for monitoring solar activity, reached a 23-year high. But the number of X-class flares has been the ...

The Origin of the Sun's Magnetic Field Could Lie Close to Its Surface May 22, 2024 — Surprise findings suggest sunspots and solar flares could be generated by a magnetic field within the Sun's ...

On a hot and humid Florida night in late August 1859, the sky suddenly lit up. But it was not from fireflies or a fireswamp.

The Farmers' Almanac predicts a “Thunder and Zing Spring” for 2025 across much of the United States, though Texas is forecast ...

This phase is characterized by an increase in sunspots and solar flares, impacting Earth through geomagnetic storms that can disrupt satellites, power grids, and communicatio... In May 2024 ...

Solar material is gusting out of the dark patch in the Sun's corona towards Earth at more than a million miles per hour.

The Kodaikanal Solar Observatory (KSO), established in 1899, has made significant contributions to understanding solar phenomena like sunspots, flares, and coronal mass ejections.
