Photosphere - Wikipedia The photosphere is a star's outer shell from which light is radiated It extends into a star's surface until the plasma becomes opaque, equivalent to an optical depth of approximately 2⁄3, [1] or equivalently, a depth from which 50% of light will escape without being scattered
Photosphere | Sun’s Surface, Solar Radiation Solar Flares | Britannica Photosphere, visible surface of the Sun, from which is emitted most of the Sun’s light that reaches Earth directly Since the Sun is so far away, the edge of the photosphere appears sharp to the naked eye, but in reality the Sun has no surface, since it is too hot for matter to exist in anything
The suns atmosphere: Photosphere, chromosphere and corona The photosphere is the lowest layer of the sun's atmosphere — the innermost layer we can observe directly The term photosphere means "sphere of light" and is the layer where most of the sun's
Photosphere - NSO - National Solar Observatory The photosphere radiates the light we see from the Sun This is the first and bottommost layer of the Sun’s atmosphere It’s the part of the Sun we are most familiar with because it represents the visible “surface” we see
NASA Marshall Solar Physics The photosphere is the visible surface of the Sun that we are most familiar with Since the Sun is a ball of gas, this is not a solid surface but is actually a layer about 100 km thick (very, very, thin compared to the 700,000 km radius of the Sun)
The Solar Photosphere - Stanford University 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 When we observe sunspots and faculae (bright little cloud-like features) we are observing them in the photosphere
The Surface of the Sun - Center for Science Education The photosphere is a thinner, cooler layer than its neighboring layers It is only about 500 km (300 miles) wide, a much thinner layer than the interior solar regions The temperature of the photosphere is around 5,500 °C (9,900 °F), which is much cooler than the Sun's core
Facts About The Suns Photosphere - Sciencing The surface of the sun, or photosphere, is a yellow-colored layer of thick, hot gases marked with dark spots, known as sunspots It is the lowest visible layer of the sun
Photosphere - an overview | ScienceDirect Topics The visible region of the sun is called the photosphere, where most of the electromagnetic energy reaching the earth originates Although the sun is a gaseous body, the photosphere is referred to as the surface of the sun
