This is interesting.... But I don't understand why people spend millions of dollars for looking about a planet ... Can't travel him.... While we are destroying our planet we live in
Spending money in keeping our planet.. Better than spending money in search of an inaccessible planet.
Studying other solar system gives us valuable information about our universe. It teaches about the origin of the universe, the planets, the stars, the climate, the development of life and much more. All this information can help us better understand our planet and what we need to do to keep it in a good shape.
