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 ...

Our Sun has been burning brightly for currently about 4.5 billion years and will continue to do so for another 7 billion years or so. A photon from the surface of the Sun takes about 8 minutes and 20 ...

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 ...

Deep beneath the surface of the sun lies a razor-thin transition zone called the tachocline. Despite being only a sliver in size, the tachocline is believed to be the engine room of the un’s magnetic ...

Scientists have advanced in their quest to create an accurate model of the sun's inner workings, which could pave the way to a better understanding of our solar system. Accurate solar models might ...

Massive, long-lasting plasma flows 15 times the diameter of Earth transport heat from the sun’s depths to its surface, according to a study in the Dec. 6 Science. The finding supports a decades-old ...

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 ...
