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 ...

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 ...

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 ...
