Solar activity is essentially an expression of changing magnetic fields in the sun's atmosphere. Recent observations substantiate a comprehensive theory that explains the 11-year magnetic cycle ...

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 ...

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 ...

In Solar Cycle 25, the Sun has spent the last near-decade building strong magnetic fields at its poles through convection. As those fields become stronger and less stable, they're bound to flip ...

Scientists have raised concerns about the potential disruption to global communication infrastructure, including the internet, due to increased solar storms and flares during the Solar Maximum phase.

There may be more northern lights – or aurora borealis – sightings this spring. During the March and September equinoxes, the Earth's axis is parallel to the sun's. According to the Russell ...

Within 90 seconds of the aurora's reaching the skies above Quebec, magnetic ... the solar cycle. The sun, like the Earth and most of the planets, is a huge magnet, with its own force field ...

The sun’s constant ... 11-year cycle; at the end of the process, eruptions of energy unleash charged particles that rush ...

Solar physics is the study of the fundamental processes occurring in the sun. Primarily this is related to the dynamics of plasmas and their interplay with the sun’s magnetic fields, and how ...
