The sun's atmosphere: Photosphere, chromosphere and corona
2022年6月21日 · The sun's atmosphere has three layers: the photosphere, the chromosphere and the corona. We explore each layer in more detail here.
Sun - Wikipedia
The Sun's atmosphere is composed of five layers: the photosphere, the chromosphere, the transition region, the corona, and the heliosphere. The coolest layer of the Sun is a temperature minimum region extending to about 500 km above the photosphere, and has a temperature of about 4,100 K. [77]

2024年2月3日 · The solar atmosphere is the outermost region of the Sun, visible during total solar eclipses. It consists of three primary layers: 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 ...
The Sun’s Atmosphere: Layers and Features Explored
The Sun’s atmosphere is a complex system with distinct layers, each playing a crucial role in the star’s ability to influence our planet. The lowest part of the solar atmosphere is the photosphere, which is the visible surface we observe with the naked eye or standard telescopes.

2012年10月10日 · This graphic shows a model of the layers of the Sun, with approximate mileage ranges for each layer: for the inner layers, the mileage is from the sun’s core; for the outer layers, the mileage is from the sun’s surface. The inner layers are the Core, Radiative Zone and Convection Zone.

2025年1月17日 · Sun - Solar Atmosphere, Radiation, Core: Although there are no fires on the surface of the Sun, the photosphere seethes and roils, displaying the effects of the underlying convection. Photons flowing from below, trapped by the underlying layers, finally escape.
Layers of Sun - Internal Structure of the Sun, Sun's Atmosphere
The atmosphere of the Sun is formed by its outer layers. There are primarily three layers that make up the atmosphere which is named as the core, the radiative zone, and the convective zone. These are the internal parts of the Sun.
Layers of the Sun: Structure & Composition with Diagram
2023年2月2日 · It forms the atmosphere of the sun. The sun’s energy radiates up from the sun’s interior out to these outer layers, which we see as sunlight. There are four layers here: 1. Photosphere. Temperature: 6500 Kelvin at the bottom to 4000 Kelvin at …
15.1 The Structure and Composition of the Sun – Astronomy
The region of the Sun’s atmosphere that lies immediately above the photosphere is called the chromosphere. Until this century, the chromosphere was visible only when the photosphere was concealed by the Moon during a total solar eclipse (see the chapter on Earth, Moon, and Sky ).
15.1: The Structure and Composition of the Sun
2022年4月11日 · Explain what happens in the different parts of the Sun’s atmosphere; The Sun, like all stars, is an enormous ball of extremely hot, largely ionized gas, shining under its own power. And we do mean enormous. The Sun could fit 109 Earths side-by-side across its diameter, and it has enough volume (takes up enough space) to hold about 1.3 million ...
