   Feb 3, 2024 · Photosphere. Thickness/Size: Approximately 500 kilometers. Temperature: Around 5,500°C. Characteristics: The photosphere is the Sun’s visible surface, where light is emitted that we see from Earth. It’s marked by granules and sunspots, which are manifestations of the Sun’s magnetic activity.

   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.

   What are the characteristics of a photosphere?

   • Thickness/Size: Approximately 500 kilometers. Temperature: Around 5,500°C. Characteristics: The photosphere is the Sun’s visible surface, where light is emitted that we see from Earth. It’s marked by granules and sunspots, which are manifestations of the Sun’s magnetic activity. Below this layer, the Sun is opaque to visible light.

   What happens if we look through a photosphere?

   • Something similar happens in the Sun. Its outer atmosphere is transparent, allowing us to look a short distance through it. But when we try to look through the atmosphere deeper into the Sun, our view is blocked. The photosphere is the layer where the Sun becomes opaque and marks the boundary past which we cannot see (Figure 15.5).

   What is a photosphere & why is it important?

   • (Image credit: NASA/SDO) 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 energy is emitted. It takes about eight minutes for sunlight from the photosphere to reach Earth.
