The sun's convection zone plays a key role in the generation and evolution of the Sun's magnetic field. Analyzing data sets spanning more than 20 years, researchers have obtained the most ...

The sun has long intrigued scientists. However, this sphere of super-heated plasma—the closest star to Earth—is also notoriously difficult to study, leaving many unanswered questions. Now, researchers ...

The Sun's magnetic activity follows an eleven-year cycle. Over the course of a solar cycle, the Sun's magnetic activity comes and goes. During solar maximum, large sunspots and active regions appear ...

Go deep into the sun and uncover the secrets of its convective zone radiative zone and core Learn how nuclear fusion produces unimaginable energy and powers life on Earth Discover how photons take ...

New simulations suggest that the origins of the sun's explosive storms could lie much closer to its surface than first thought. When you purchase through links on our site, we may earn an affiliate ...

Different stars can exhibit different levels of activity. The Sun's signs of solar activity are rather feeble on an astronomical scale. Other stars are up to ten times more active. While researchers ...

Seth Putterman started out studying the behavior of plasma for national security reasons. Extremely fast hypersonic missiles heat and ionize the surrounding air and form a cloud of charged particles ...

Science 101 tells us that the twinkling appearance of stars from our vantage point on Earth is due to atmospheric effects: winds and varying temperatures and densities in the air bend and distort the ...

Understanding the Sun's magnetic dynamo could help predict solar weather, such as potentially dangerous geothermal storms, solar flares and sunspots. Mathematicians have proposed a new model of the ...

Astronomers at the Solar & Heliospheric Observatory (SOHO) captured this image of a solar prominence erupting from the surface of the Sun on October 25, 2002. Two large prominences were spotted and ...
