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

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

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

A geomagnetic storm watch predicts northern lights across the northern U.S. and Midwest this week, following solar eruptions ...

Nov. 11, 2024 — Like the Earth, the Sun likely has swirling polar vortices, according to new research. But unlike on Earth, the formation and evolution of these vortices are driven by magnetic ..

As the sun reaches its solar maximum, a strong solar flare erupted on March 28, which may enhance the visibility of the northern lights and disrupt technology.

solar flares and coronal mass ejections is not constant. Instead, it rises and falls throughout an 11-year solar cycle. At the bottom of this solar cycle, called solar minimum, months can pass ...

ESA’s Solar Orbiter recorded a giant plasma structure extending millions of kilometres from the Sun’s surface. The footage, taken on October 12, 2022, shows a swirling motion in the solar wind ...

At the peak of the cycle — called solar maximum — sunspots, flares and CMEs are commonplace. We have tracked solar cycles for hundreds of years by counting the number of sunspots on the sun.
