There’s a lot less landmass, which negates the impact of perihelion. At solar maximum, the sun's most active phase of its 11-year cycle, produces more light, energy and solar radiation.

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 through solar maximum ...

On Dec. 26, NASA’s Parker Solar Probe went where no mission has gone before and came within 3.8 million miles (6 million kilometers) of the Sun’s surface, flying through the solar corona ...

The obvious reason for the increased frequency is the arrival of solar maximum. This peak in the sun's roughly 11-year cycle of activity, which is triggered by the weakening and eventual flipping ...

The landmark Ivanpah solar energy plant along Interstate 15 near the Nevada-California border is past its prime, left in the ...

As the sun geared up to spit a powerful solar flare into space, NASA scientists snapped huge loops of plasma leaping from the sun's surface. These spectacular solar structures, known as coronal ...

The sun started 2025 with a bang as it fired off a powerful solar flare this morning. The X-class solar flare peaked at an X1.2 at 6:40 a.m. EST (1140 GMT) on Friday (Jan. 3), releasing a blast of ...
