Include recent findings in your answer . Scientist are looking into sending spacecrafts to the sun without a person having to be inside due to the extreme temperature. Discuss the overall benefits that may be derived from space exploration. Overall benefits that may be derived from space exploration is finding another planet that could be inhabited, finding life that could possibly be out there and many more.

Galaxy- The collection of many stars, dust and gas in however many solar systems and is all held together by gravity Milky Way- The galaxy Earth is in. The name came from the shape of the galaxy. How does solar wind form? Solar wind forms from the outward expansion of Plasma from the suns Corona solar.
