Solar activity is still increasing in a sunspot cycle that is proving way more intense than scientists predicted. Just how much stronger is it going to get?

Nunalleq, a village in what’s today southwest Alaska, seemed to have thrived during the Little Ice Age. How did this village manage to survive and prosper during this time period? And what caused this period of climate change in the...

Dr. Steve Johnson, Senior Scientist of the Space Radiation Analysis Group, discusses what's being done right now to document radiation exposure, not only to ensure our astronauts stay healthy, but to understand weather in space. HWHAP...

A massive storm over the Sun discharged the largest solar flare in three years on Sunday, No. 29. <br/>

The Sun's energy is one of the biggest forcings on Earth's climate, and for years satellites have measured total solar irradiance. Glory will continue collection of this critical climate data, which will contribute to the long-term...

The Sun is stirring from its latest slumber. As sunspots and flares, signs of a new solar cycle, bubble from the Sun’s surface, scientists are anticipating a flurry of solar activity over the next few years. Roughly...

The number of sunspots increases and decreases over time in a regular, approximately 11-year cycle, called the sunspot cycle. The exact length of the cycle can vary. It has been as short as eight years and as long as fourteen, but the...

Learn about the science behind nature's most spectacular light show. Caused by the sun, solar wind interacts with Earth's magnetic shield and reacts with gas molecules creating the visible aurora.
