**WHAT DOES THE INSIDE OF THE SUN LOOK LIKE?**

The sun is made out of layers. The core is located in the center. This is where the suns energy is created. From the core, energy travels to the radiation zone. In this zone, energy is carried by the particles of light. In approximately a million years, the energy then travels to the convection zone. In this zone, the speed at which energy travels will greatly increase. The sun has never been traveled to. It is impossible to travel to the sun. The closest that austronauts have ever been to the sun is the moon which is 250,000 miles away from the earth. The sun itself is much further away with a measurement of 93,000,000 miles.

**It is believed that the sun is made out of gases from the universe.The gravity is what makes the sun hot and dense. The sun also contains sunspots which are the cause of the loops from the suns [|magnetic field]. To be able to look at the sun and keep track of it, scientists use telescopes. Over the years, the surface of the sun has been calmer which makes it easier to see. As solar physicist Dean Pesnell said" That's perfect timing. The sun is experiencing a cenutry-class solar minimum, offering the clearest possible views." Right now, NASA is launching a program caled the "Solar Dynamics Observatory." This program is promised to see into the surface of the sun. Solar physicist Todd Hoeksema commented "There's a lot going on inside the sun that we do not understand. The [|Solar Dynamics Observatory] is bound to deliver some big discoveries the inside of the sun is easier to see when the suns surface of the suns interior is calm. One difficulty that scientists have with the vision of the sun is that they cannot see beyond the outer surface of the sun. This program senses the acoustic waves of the sun moving into it and it sees these waves to have a clear image.** =====



Interesting information: The sun weighs 4.40x10^30 pounds. This is the weight of 340,000 earths. The suns length is 860,000 miles. If you were to drive across the sun in a car, it would take you approximately 1.5 years. The temperature of the suns core measures to approximately 27 million degrees Fahrenheit. The surface is not as hot with a measurement of only 10,000 degrees Fahrenheit. If we imagined a road to the sun and drove by car, it would take you an entire length of 160 years. It is believed that the sun was formed by a large amout of gases and dust. The core takes up one fourth of the sun. It is believed that in approximately 4.5 billion years, the core will run out of energy and collapse and will cause the other parts of the sun to be blown up.

A question of wonder: "Why does the sun sometimes turn orange in the morning and bright white in the afternoon?" Answer: "As the sun rises in the morning, it passes through the earths atmosphere. The air scatters blue and green light. In the afternoon, only a few blue and green lights are scattered. This makes it bright white. If the blue and green light is taken away from the white light, this will form a color of orange and red. This is why the sun turns orange."
