Here's a breakdown of what you might be referring to and what the correct terms are:
* The Sun's surface: The visible part of the Sun that we see is called the photosphere. This is where the light we see originates. It's not a solid surface, but a layer of gas where the Sun becomes opaque to light.
* The Sun's atmosphere: The Sun has several layers of atmosphere above the photosphere, including the chromosphere and corona. These layers emit light, but they are much fainter than the photosphere and can only be seen during eclipses or with specialized instruments.
* The Sun's light: The light we see from the Sun is a combination of different wavelengths, including visible light, infrared radiation, and ultraviolet radiation. The Sun constantly emits these wavelengths in all directions.
So, there isn't a specific name for a "sphere of light" around the Sun. It's more accurate to say that the Sun is a sphere of hot gas that emits light and radiation in all directions.
