a magnetic field reversal. The sun undergoes such a reversal every 11 years, which marks an important stage in the solar cycle. The shift in polarity marks the point at which the sun is halfway ...

Even if the specific monthly peak of the cycle has passed, it doesn't mean solar activity is over. Strong solar activity ...

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 ...

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 ...

There may be more northern lights – or aurora borealis – sightings this spring. As we near the spring equinox, also known as the vernal equinox, on March 20, the Earth's magnetic field and ...

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.

A giant, black region of the sun — called ... and powerful solar flares will become more common, Young said. That can be a concern since the powerful magnetic fields from coronal mass ejections ...

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 ...

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 ...
