Sunlight damage extra credit


What happens if you look into the sun for to long? If you stare directly into the sun you can damage your eyes and become temporarily partially blind. The sun gives out UV rays which can almost cause a sunburn on your eye. If you look at the sun directly and don't use the right tools it can cause damage.If you look at the sun with unfiltered binoculars it can deliver over 500 times as much energy to the eye, making it very dangerous. Even small glances at the Sun through unfiltered binoculars can cause permanent blindness. So don't stare at the sun!

What Will Happen to the sun? extra credit


The sun is in its midlife stage, meaning its making a lot of helium and hydrogen atoms. Right now the surface temperature of the sun is getting hotter and the sun is getting brighter. In its early stages it used to be a lot less bright. But the sun will die out and shed its layers and become a dim white dwarf planet. Making the earth have no heat.

The picture is of a star exploding like the sun will in many many years

What's the Suns core made of? extra credit


The Sun's core has a very high temperature, more than 15 million degrees Kelvin. The core of the sun is very very dense. The core of the sun is so hot that it destroys all of the neutrons. then the electrons and protons supply the core. the very high temperature also makes the protons and electrons move very very fast which makes the core very dense. When the Protons and Electrons are moving so quick the slam into each other and create fusion suppling the sun with its energy

life on the sun and other planets



My planet, the sun, does not have liquid Water. It is way to hot to keep water. The sun does have a magnetic field.
The Sun consists mainly of hydrogen and helium. I don't think there is life on the sun. I think it is way to hot to support any life and there is no oxygen atmosphere so we could not breathe.
I think life could be on Europa. Europa's Jupiter's fourth largest moon. Some scientist believe that life could be on it because its very smooth, and doesn't have much craters. Also It has a huge frozen ocean, one of the biggest in the entire solar system. Its frozen and its -260 Fahrenheit. I might think that we can liv eon europa. Maybe if we had a special suits to make us not freeze to death, But it is very possible.

distance....


Space is measured in different ways. One way is AU meaning astronomical units. This is used when you want to measured anything between the sun and the earth. KM is used on earth, to measure big distance lets say form a town to a town. LY, is light years, they are huge. They are used to measure big spaces in the universe.
We are 1 AU from the sun. I Don't think we will ever be able to land on the sun. It is way to hot and it is far to get there. we have a better chance going on the moon than the sun.
