The inside stuff:• Core:
The inside stuff:• Core:
– The inner most layer of the sun.
The inside stuff:• Core:
– The inner most layer of the sun.
– Temperatures in the core reach about 15,000,000 °C.
The inside stuff:• Core:
– The inner most layer of the sun.
– Temperatures in the core reach about 15,000,000 °C.
– Nuclear fusion happens here.
The inside stuff:• Core:
– The inner most layer of the sun.
– Temperatures in the core reach about 15,000,000 °C.
– Nuclear fusion happens here.
– The energy produced at the core today will not reach the surface of the sun for a few hundred thousand years.
The inside stuff:• Radiation Zone:
The inside stuff:• Radiation Zone:
– A zone of tightly packed gases.
The inside stuff:• Radiation Zone:
– A zone of tightly packed gases.
– Transfers the energy from the core in the form of electromagnetic energy.
The inside stuff:• Radiation Zone:
– A zone of tightly packed gases.
– Transfers the energy from the core in the form of electromagnetic energy.
– The temperature ranges from 2,000,000°C to 7,000,000°C.
The inside stuff:• Convection zone:
The inside stuff:• Convection zone:
– Outermost layer of the sun’s interior.
The inside stuff:• Convection zone:
– Outermost layer of the sun’s interior.
– Convection currents here keep the energy moving towards the surface of the sun.

The Atmosphere:• Photosphere:
The Atmosphere:• Photosphere:
– The visible portion of the Sun.
The Atmosphere:• Photosphere:
– The visible portion of the Sun.
– Means sphere that gives off light.
The Atmosphere:• Photosphere:
– The visible portion of the Sun.
– Means sphere that gives off light.
– The temperature is about 6,000°C.
The Atmosphere:• Chromosphere:
The Atmosphere:• Chromosphere:
– The portion that radiates most of the ultraviolet light.
The Atmosphere:• Chromosphere:
– The portion that radiates most of the ultraviolet light.
– The temperature is about 10,000°C.
The Atmosphere:• Corona:
The Atmosphere:• Corona:
– Extends several million kilometers from the “surface” of the sun.
The Atmosphere:• Corona:
– Extends several million kilometers from the “surface” of the sun.
– The temperature is about 1,000,000°C.
The Atmosphere:• Corona:
– Extends several million kilometers from the “surface” of the sun.
– The temperature is about 1,000,000°C.
– Most of the Sun’s X-ray energy comes from here.
The Atmosphere:• Solar Winds:
The Atmosphere:• Solar Winds:
– A stream of charged particles that are “blown” away from the sun.
The Atmosphere:
Features of the Sun:• Sunspots:
Features of the Sun:• Sunspots: Cooler areas on the
Sun’s “surface”.
Features of the Sun:• Sunspots: Cooler areas on the
Sun’s “surface”.– Caused by magnetic fields on the
“surface” of the sun.
Features of the Sun:• Sunspots: Cooler areas on the
Sun’s “surface”.– Caused by magnetic fields on the
“surface” of the sun.
– As cool as 4,000 °C.
Features of the Sun:• Sunspots: Cooler areas on the
Sun’s “surface”.– Caused by magnetic fields on the
“surface” of the sun.
– As cool as 4,000 °C.
– Run in cycles of about 11 years.
Features of the Sun:
Sun spots:
Features of the Sun:• Solar Prominences:
Features of the Sun:• Solar Prominences: Gases trapped
in the magnetic field lines that connect sun spots.
Features of the Sun:• Solar Prominences: Gases trapped
in the magnetic field lines that connect sun spots.– Can rise up to 100,000 km above the
“surface” of the sun.
Solar Prominence:

Features of the Sun:• Solar Flares:
Features of the Sun:• Solar Flares: Happen when solar
prominences connect together.
Features of the Sun:• Solar Flares: Happen when solar
prominences connect together.– Super heated gases (millions of
degrees) on the “surface” erupt into space.
