NASA's Solar Dynamics Observatory captured sunspot AR3386 blast a long-duration X1.6-class solar flare and X1 flare. See time ...

The sun typically goes through regular cycles of increased and decreased activity, but in recent years, it hasn't been ...

The Sun exhibited unpredictable behavior with two strong solar flares in late November and early December 2025. These events, captured by NASA's Solar ...

Sunspot AR3165 has erupted with several m-class solar flares in a span of a few hours. NASA Solar Dynamics Observatory ...

A powerful M8.1 solar flare sent a full-halo coronal mass ejection toward Earth, and scientists expect it to trigger strong G3 geomagnetic storm levels on Tuesday. Forecasts show the Kp index rising ...

On December 8, 2025, the sun unleashed a significant solar flare, classified as an X-class event, raising concerns among scientists and technology experts alike. This article will explore the ...

Activity on the sun is not constant; it varies along a cycle of about 11 years. The peak of this solar cycle — called solar maximum — is when sunspots, solar flares and coronal mass ejections (CMEs) ...

LAS CRUCES, N.M. (KRQE) – Normally only visible much closer to the north pole, the Northern Lights have been seen as far south as New Mexico in recent years. These beautiful light shows are caused by ...

Solar flares can be many times the size of Earth and can damage things like satellites. A new study suggests that eruptions from the sun can be even hotter than researchers thought. Solar flares are ...

What processes are responsible for heating solar flares and what dangers do they pose to Earth? This is what a recent study published in The Astrophysical Journal Letters hopes to address as an ...

Beautiful yet dangerous solar flares that erupt from the sun could be as hot as 180 million degrees Fahrenheit, researchers say. That's more than six times hotter than solar physicists previously ...
