There's a space joke so old you're unlikely to find its provenance on the internet: If you want to visit the sun, go at night. If you're scratching your head about the punchline, that's because the sun, our solar system's star that provides heat and light, is a blindingly ...
Despite being so hot, the corona is less than a millionth as bright as the Sun. As you walk away from a bonfire, you feel less of its heat because you receive less energy due to the inverse square law. Why is the more distant corona so much hotter than parts of the Sun closer to...
Next on our journey outwards from the centre of the Sun, is the convective zone, where bubbles of plasma carry the heat to the surface like a giant lava lamp. Temperatures at the bottom of the convective zone are 2 million degrees. Finally, the surface, the part of the star that we ca...
The sun, a massive nuclear-powered source of energy at the center of the solar system, generates the heat and light that sustain life on Earth. But how hot is the sun? The answer is different for each part of the sun. Arranged in layers, the sun varies in temperature: It is hottest...

The sun radiates energy in all directions. Most of it dissipates into space, but the tiny fraction of the sun's energy that reaches Earth is enough to heat the planet and drive the global weather system by warming the atmosphere and oceans. The delicate balance between the amount of heat ...
