Massive solar flares, graceful eruptions of solar material, and an enormous sunspot make up some of the imagery captured by NASA's Solar Dynamics Observatory in 2013 and 2014. A year ago this weekend, ...

After a calm week, the sun erupted again. A powerful M5.1 solar flare burst from an emerging sunspot region, shaking the ...

The sun has become more and more active over the last 16 years, in a turn that surprised scientists and could affect space weather and technology on Earth, NASA announced this week. A new research, ...

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) ...

Space weather forecasters issued an alert on Tuesday for incoming severe solar storms that could produce colorful northern lights and temporarily disrupt communications. In the past few days, the sun ...

Back in 2019, a consortium of scientists predicted August 2025 as the peak of the solar activity cycle. But where are we now? When you purchase through links on our site, we may earn an affiliate ...

A massive solar storm has delayed the launch of Blue Origin's New Glenn rocket for a second time. The rocket is scheduled to carry NASA's ESCAPADE twin satellites on a mission to Mars. The Space ...

New research suggests that the unexpected intensity of the ongoing solar maximum may be partly tied to a lesser-known, 100-year solar cycle. If true, solar activity could spike further in the coming ...

A year ago this weekend, the sun’s activity created some of the most spectacular auroras on record, with displays visible as far south as Florida. The incredible spectacles last May (and another ...

Solar activity, manifested primarily through sunspots, solar flares and coronal mass ejections, has long influenced both the near-space environment and terrestrial systems. Over millennia, variations ...
