Go deep into the sun and uncover the secrets of its convective zone radiative zone and core Learn how nuclear fusion produces ...

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 ...

Last time, I talked about how the Sun, the source of practically all life on our planet, was pretty slack with its nuclear burning. It did so little of it, that (volume for volume) it put out about as ...

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 ...

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 ...

How do you power a super advanced alien civilization? Soak up a star. We harness the power of the sun using solar panels. What if you were to scale this idea to astronomical proportions? Surround an ...

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 ...

“What appliance can pierce through the outer layers of a star and test conditions within?” asked Arthur Eddington in his book The Internal Constitution of the Stars (Cambridge University Press, 1926).
