Big Ball of Hot Plasma and Nuclear Fusion that Holds Our Solar System Together

# data[].attributes.body
The one and only!

# data[].attributes.body
No, the Sun is not a vegetable. Do not attempt to eat it.

# data[].attributes.body
The core is the innermost layer of the Sun. This area of the Sun is incredibly dense (10 times the density of gold) and hot (27 million degrees Fahrenheit), and it is where nuclear fusion occurs.
it is about 0.2-0.25 of the solar radius.

# data[].attributes.body
The sun's radiative zone is where radiation from the core travels out to the outer convective zone. It forms about 70% of the Sun's radius. It can take photons thousands of years to leave this zone, since it is of varying densities and there are so many other photons all bouncing around.

# data[].attributes.body
This area of the sun is very tumultuous. Plasma is heated by the sun's inner regions and rises to the surface, where it cools and sinks back to the bottom of the convection zone. Since the sun is rotating, this convection happens in a swirling fashion. Unlike the Earth, or other solid bodies, the sun's equator rotates faster than its poles. The spinning also produces magnetic fields.

# data[].attributes.body
The Sun's photosphere is the visible "surface" of the sun. It contains sunspots, and it is only about 100 km thick. Light and heat radiate from this layer. Relatively cool and dark areas called "sunspots" can be found on this layer.

# data[].attributes.body
The Sun's chromosphere is an irregularly shaped layer of the sun. It is about 20,000 degrees Celsius. When it is viewed with the proper spectrograph or filter, a lot of hidden features can be seen, such as bright spots around sunspots, or prominences. It is the site of a lot of activity, such as prominences and filament eruptions.

# data[].attributes.body
The sun's corona is the outermost layer of its atmosphere. It is almost always invisible to observers on Earth until a total solar eclipse. It is the source of solar winds.

# data[].attributes.body
Sunspots are cooler areas of the sun's photosphere. The photosphere usually has a temperature of about 5,800 Kelvin, while sunspots are only 3,800 K. They occur over regions of intense magnetic activity.

# data[].attributes.body
Solar prominences are massive and bright solar features that extend from the sun's surface. They may last for a day or more. They are made of plasma.

# data[].attributes.body
Solar flares are powerful radiation blasts. They can't directly kill a human or other living creatures, but they can wreak havoc on electrical instruments and our satellites.

# data[].attributes.body
This beautiful natural phenomenon occurs when electrons collide with the upper parts of the Earth's atmosphere. These electrons collide with gasses long enough to energize the for short amount of time, causing them to light up.
