Explore Earth's hidden layers beneath our feet. This kid-friendly guide includes a neat diagram and fun descriptions of the 4 layers of the Earth.

Discover interesting facts about the sun, the solar system's central star that supports all life on Earth.

After that, the sun's outer layers will expand, and it will become brighter. However, the surface temperature will cool by about half, which will change the sun's light from bright white to red.

The sun's atmosphere has three layers: the photosphere, the chromosphere and the corona. We explore each layer in more detail here.

Meanwhile, the EUI images our star in ultraviolet light, which allows scientists to study the superheated plasma in the sun's outer atmosphere, the corona, which can reach temperatures as great as 5.4 ...

Victor Pizzo, a physicist at the National Oceanic and Atmospheric Administration's Space Environment Center, explains. The fact that the sun's corona is very hot--one million to two million ...

Our Sun is currently in its middle age, about 4.6 billion years old, ... After its red giant phase, the Sun will shed its outer layers, forming a beautiful but fleeting planetary nebula.

I didn’t see his layers forming. That’s the rub of parenting. Life is in the little moments, and parenting is mostly little moments.

Flow zone. The sun is a white-hot ball of plasma that's boiling on its surface. This boiling region is called the "convection zone," where layers and plumes of plasma roil and flow.

Have you ever wondered what’s inside the Sun, the massive star that powers our solar system? In this video, we take a deep dive into the Sun’s mysterious interior, breaking down its layers ...

Surprise findings suggest sunspots and solar flares could be generated by a magnetic field within the Sun’s outermost layers. If confirmed, the findings could help scientists better predict ...
