A photosphere is the region of a luminous object, usually a star, that is transparent to photons of certain wavelengths. Stars, except neutron stars, have no solid or liquid surface. [note 1] …

photosphere, visible surface of the Sun, from which is emitted most of the Sun’s light that reaches Earth directly.

The photosphere is the lowest layer of the solar atmosphere. It is essentially the solar "surface" that we see when we look at the Sun in "white" (i.e. regular, or visible) light.

The surface of the Sun is called the photosphere, a term which means “sphere of light.” The glowing ball of light that you see in the sky is the photosphere.

The photosphere is defined as the well-defined surface of the Sun where most visible light is emitted, consisting of hot plasma held together by gravity. It is characterized by the presence …

The photosphere is the lowest layer of the Sun's atmosphere and is the visible surface we see from Earth. The name originates from the Greek words 'photos' (light) and 'sphaira' (sphere), …

The photosphere plays a crucial role in the Sun's luminosity, affecting solar radiation that reaches Earth and potentially influencing climate change. Observing this layer has revealed significant …

It’s the part of the Sun we are most familiar with because it represents the visible “surface” we see. The Sun doesn’t really have a solid surface since it is a huge ball of gas and plasma. …

We term the region where this happens the apparent surface, or the photosphere. The photosphere is the disk you see in the sky when you look at the Sun through a filtered …

The point where it appears to become completely opaque is called the photosphere. Thus, the photosphere may be thought of as the imaginary surface from which the solar light that we see …
