An uncommon double solar eruption has sent two coronal mass ejections towards Earth, which are expected to arrive Wednesday.

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.

Even if the specific monthly peak of the cycle has passed, it doesn't mean solar activity is over. Strong solar activity persists for a year or two beyond the maximum date, so we still have some time ...

Solar flares are classified based on their strength and fall into five designated categories: A, B, C, M and X. An X-class ...

Solar flares are intense bursts of electromagnetic radiation that erupt from the sun’s surface, usually from magnetically active regions like sunspots. When the sun's magnetic fields tangle, break, ...

Sunspot numbers are usually high for a couple ... and within it the solar wind particles course along magnetic field lines that channel their movements. The eye-catching computer graphics Deehr ...

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 ...

Most of the time, the Earth and Sun’s magnetic fields are misaligned ... Solar maximum is a period that can see a drastic increase in sunspots, solar flares, and coronal mass ejections, which ...
