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 ...

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 ...

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'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 ...

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 ...

“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).

With scientists measuring energy waves traveling through stars and setting them to music, the familiar tune takes on a whole new meaning. When you purchase through links on our site, we may earn an ...

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 ...

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 ...
