Astronomers track the sun's 11-year cycle by counting sunspots. Also, we're expecting a strong geomagnetic storm and aurora ...

The sunspots are the visible evidence of the solar magnetic field changing its polarity, and appear as darker areas where there is a greater strength of magnetic flux in the sun’s photosphere.

Study shows that deep learning predicts TEC variations in the ionosphere, minimizing failures in satellite signals during ...

The sun was well observed during the period of the Maunder Minimum and this lack of sunspots is well documented. This period of solar inactivity corresponded to a climatic period called the ‘Little ...

The Sun's activity typically peaks at solar maximum, but there's an even more dangerous stage it could enter, and with ...

Helioseismic and Magnetic Imager (HMI) image of the big sunspot that occurred on 5 May 2024, in magnetic field. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news ...

Thus a change in the number and location of sunspots reveals changes in the magnetic field of the Sun. It turns out that what’s behind the solar cycle is these periodic changes in the Sun’s ...

According to the Russell-McPherron effect, the magnetic fields of the Earth and the solar ... When the sun is "active," it produces more sunspots, which appear as black splotches on the face ...

Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the aurora-causing effects of the solar wind. However, towards the equinox, the two fields ...

A G3 geomagnetic storm is predicted to strike Earth, with displays of the Northern Lights possible across northern U.S.

The sunspot, named 3856, is facing Earth and has developed a volatile type of magnetic field known as a "beta-gamma-delta" ...

They're cooler regions of gas, some as large as the entire Earth. The sunspots are produced by powerful magnetic fields coming from inside the sun, which, on one hand, would fry your electronics ...
