SOLAR SYSTEM

Detailed explanation-1: -The hunt for an answer also is revealing important details about our own place in the universe – where we came from, how life came about and, perhaps, where we’re headed. The years and decades ahead will bring us ever closer to the ultimate in self-reflection: a mirror image of our own planet Earth.

Detailed explanation-2: -We must have food, water, air, and shelter to survive. If any one of these basic needs is not met, then humans cannot survive. Before past explorers set off to find new lands and conquer new worlds, they had to make sure that their basic needs were met.

Detailed explanation-3: -Essential elements of life-oxygen, water, air, etc.-are lacking on other planets. However, scientists are still searching to look for signs of life on other planets. Therefore, humans can survive on other planets only if they possess essential elements of life.

Detailed explanation-4: -What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.

Detailed explanation-5: -No other planet in our solar system currently has the conditions to support life as we know it on Earth. Even if scientists discover another habitable planet outside of our solar system, humans do not yet have the technology to visit it.

Detailed explanation-6: -To conclude, any new human colonisation on another planet would be very difficult. The extreme weather conditions, the chemistry of the atmosphere and the vast amounts of resources needed to support human life all play into this.
