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 ...

In their interiors, stars are structured in a layered, onion-like fashion. In those with solar-like temperatures, the core is followed by the radiation zone. There, the heat from within is led ...

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 ...

Spinning around: the green arrows represent rotation speed in the stellar convection zone. Differential rotation is inferred from the oscillatory motions of the star seen as orange/blue shades on the ...

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 ...
