The Sun

What is the convection zone of the Sun?

Back

The convection zone is the outer layer of the Sun's interior where energy is transferred through convection currents. Hot plasma rises, cools, and then sinks back down, creating a cycle.

Front

What are granules on the Sun's photosphere?

Back

Granules are small, cell-like structures on the Sun's photosphere, formed by convection currents of hot gases. They appear as bright spots and are a sign of the Sun's dynamic surface.

Front

What is the radiation zone of the Sun?

Back

The radiation zone is the layer of the Sun where energy radiates away from the core. It can take up to 100,000 years for energy to pass through this zone due to the dense plasma.

Front

What is convection?

Back

Convection is a method of heat transfer where warmer, less dense particles rise while cooler, denser particles sink, creating a current. This process is seen in the Sun's convection zone.

Front

What is the photosphere?

Back

The photosphere is the visible surface of the Sun that emits light and heat. It is the layer we see from Earth and is where sunspots and granules are observed.

Front

What are sunspots?

Back

Sunspots are temporary phenomena on the photosphere of the Sun that appear as spots darker than the surrounding areas. They are caused by magnetic activity and are cooler than the surrounding plasma.

Front

What is the core of the Sun?

Back

The core is the innermost layer of the Sun where nuclear fusion occurs, producing energy. It is extremely hot and dense, with temperatures reaching about 15 million degrees Celsius.

Front

What is the chromosphere?

Back

The chromosphere is a layer of the Sun's atmosphere located above the photosphere and below the corona. It is visible during solar eclipses and has a reddish color due to hydrogen emission.

Front

What is the corona?

Back

The corona is the outermost layer of the Sun's atmosphere, extending millions of kilometers into space. It is visible during a total solar eclipse and has a much higher temperature than the photosphere.

Front

What is solar prominence?

Back

Solar prominences are large, bright features extending outward from the Sun's surface, often in loop shapes. They are made of plasma and can last for several days or weeks.
