- When you see images from a telescope that are called “white light images,” you are looking at the photosphere. Strong magnetic fields are repeatedly formed and dissolved here, releasing energy and stirring up the plasma in the next layer, the chromosphere.

When all the nuclear reactions are over, a small star like the Sun may begin to contract under the pull of gravity. In this instance, the star becomes a white dwarf which fades and changes...
But more crucially, the human eye doesn’t perceive light by averaging the various colours of the spectrum together. So, a very slight excess of green light doesn’t look green to the human eye – it looks white. The Sun would have to emit only green light for our eyes to perceive it as green.
Have you ever given serious consideration to star colours? I often hear people say all stars look white. This is not true. Some show very obvious colour.
Sep 25, 2016 · For instance, the color of a star – which varies from bluish-white and yellow to orange and red – is primarily due to its composition and effective temperature.
By studying our Sun, scientists can better understand the workings of distant stars. The hottest part of the Sun is its core, where temperatures top 27 million °F (15 million °C). The part of the Sun we call its surface – the photosphere – is a relatively cool 10,000 °F (5,500 °C).
Aug 25, 2023 · Only a handful of stars show any color at all, and the vast majority are just, well, white. Looking up at the starry host, you might wonder: Why are some so colorful, while others aren’t?
