1. In Nuclear fusion, four hydrogen atoms fuse together to form Helium and a lot of energy!

2. Sunlight takes 8 minutes and 20 seconds to reach Earth. Sunlight travel through space in the form of electromagnetic wave or radiation. electromagnetic wave or radiation

3. Held in place by Earth's magnetic field, the Van Allen radiation belts swell and shrink in response to incoming energy disturbances from the sun. Earth’s magnetic field protect us from space radiation.

4. Earth’s Geomagnetic Field is protecting us. Solar Wind Solar flare Effects

5. Nuclear Fusion powers the Sun and all other stars. This happens in the Sun’s core. Hydrogen or H is the fuel of stars. Sunlight as energy. Helium as by product Neutrino as by product Sunlight takes 8 minutes and 20 seconds to reach Earth. Sunlight travel through space in the form of electromagnetic wave or radiation.

7. The Dangers of going to space. Cataract Cancer Degenerative damage Genetic mutations

10. Outside of the Earth's protective magnetosphere, astronauts are at risk from exposure to radiation from solar particle events and high- energy galactic cosmic rays. Cell and tissue damage caused by exposure to these types of radiation are distinct from that caused by terrestrial radiation sources such as x-rays, and the biological consequences are poorly understood.

11. The flow of iron in the Earth’s core produces the magnetic field that protects earth from space radiation.

12. Convection of liquid iron produces earth’s magnetic field.

13. The Earth creates the magnetic field and the magnetosphere for the planet. How does it do it? The molten iron flows like a huge river. As the iron rivers flow, they create an electric current. That current creates the magnetic field that surrounds the planet. The magnetic field created in the center of the planet makes your compass point north and protects the Earth from solar winds.

14. Earth’s ozone layer protect us from ultraviolet radiation.
