Suns photosphere1/8/2024 The photosphere is so vastly brighter than these two regions that they cannot be seen except with special instrumentation or during a total solar eclipse when the photosphere itself is blocked out. Although the sun is a gaseous body, the photosphere is referred to as the surface of the sun. This is wear the light we see from the Sun originates. The visible region of the sun is called the photosphere, where most of the electromagnetic energy reaching the earth originates. The term photosphere means 'sphere of light' and is the layer where most of the sun's. This region of the Sun is the first part of the Sun that is visible to us and we call it the photosphere. The photosphere is the lowest layer of the sun's atmosphere the innermost layer we can observe directly. Immediately above the photosphere is a relatively thin layer called the chromosphere ( sphere of color) and beyond that a large and very rarified outer atmosphere called the corona ( crown). Photosphere The material that reaches the top of the convection zone cools by giving of light. Much cooler than the core of the Sun, the photosphere has a temperature of about 10,500 degrees F, or about 5800 K. In certain wavelengths of light, the many convective columns give the Sun a slightly grainy appearance, sometimes referred to as granules or "rice grains," for its similarity to rice boiling in a pot. On close inspection with properly filtered instruments, the photosphere appears as a great cauldron with the tops of these convective currents bubbling up in a seething sea. Several methods of measuring the temperature have all determined that the Sun's photosphere has a temperature of about 5,840 K. The photosphere merely represents the outer boundary of the region in which most solar energy has been converted into visible light.īeneath the photosphere is the convective zone, a region in which huge columns of hot plasma rise and fall much like water boiling in a pot. Despite the light emitted, the photosphere is one of the coolest regions in the Sun’s atmosphere with a temperature of about 6000 K. It sometimes is referred to as the Sun's surface, but in fact the Sun has no solid surface such as that of the Earth. The Suns photosphere is a very thin layer made up of numerous granules (transient convective cells) where hot gases rise and give off light and heat. The Sun’s photosphere extends near its surface, in the region where the gas becomes opaque, with an optical depth of up to 400 kilometers. The photosphere is the layer that we see when we look directly (foolishly) at the Sun.
