Outer Core: A liquid layer of molten iron and nickel is be- neath the Earth's mantle, and is responsible for generating the planet's magnetic field. Inner Core: The Earth's solid, super-hot center is primarily composed of iron and nickel. The temperatures are as high as the surface of the sun.

There are two main forces acting in a star: Gravitational contraction: it is due to the higher layers, this force pushes mass to the center. Radiation pressure: it is produced by the inner layers, and it forces material upwards.
The star will now begin to shed its outer layers as a diffuse cloud called a planetary nebula. Eventually, only about 20% of the star’s initial mass remains and the star spends the rest of its days cooling and shrinking until it is only a few thousand miles in diameter.
The star LGM-1 is a special kind of neutron star called a pulsar. A pulsar is a rotating neutron star that shoots out a narrow beam of energy, like the spinning light in a lighthouse.

The Stars lesson plan includes three worksheets: an activity worksheet, a practice worksheet, and a homework assignment. Each one will help students solidify their grasp of the material they learned throughout the lesson.
This day focuses on one of the most awesome things we can see in the night sky: stars and star patterns that we call constellations. Stars are big exploding balls of gas — mostly hydrogen and helium — held together by their own gravity. Astronomers think that there are 200 billion stars in the Milky Way , the galaxy where our own solar ...
