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, ...

We know that the sun has entered its peak phase of activity, called solar maximum. But are we still in it, or is solar maximum already behind us? Let's see what the data has to say. However, 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) ...

Was it truly possible that the night sky over Alabama could shimmer with those otherworldly greens and pinks normally ...

The Northern Lights may ramp up in intensity for the next 50 years as the sun potentially enters a new long-term phase of heightened activity, suggests a new study by solar scientists. The night sky ...

There are many things with spots: Dalmatians, leopards, ladybugs, overripe bananas, and guys with bald spots are all great examples. Another thing with spots is the Sun! That's right! The Sun, as it ...

People in the U.S. were treated to stunning auroras last week when a powerful geomagnetic storm pushed the celestial displays as far south as Florida and Mexico. The spectacle was particularly ...

While the Sun’s solar flares strongly correlate with sunspots, observations of more than 14,000 other stars show this is not generally the case.

The sun has been unleashing a series of intense solar flares in recent weeks and much of last year as scientists forecast the sun has reached its solar maximum, an 11-year cycle. However, some ...

A solar cycle is a roughly 11-year periodic change in the Sun characterized by variations in the number and intensity of sunspots, as well as a flipping of its magnetic poles.

Climate data in a report published by the National Oceanic and Atmospheric Administration’s (NOAA) Climate.gov website found that the sun’s solar activity, including overall brightness and sunspot ...
