400 years back, human beings believed the Earth was the center of the Universe. After that, Copernicus discovered that Sun is at the center of earth orbit. However, Sun is not the center of universe. With improved space observation telescopes now we know that there are billions of galaxies, supernovas, other solar system planets that are billions of light years away from us. It is even suspected that some planets even have favourable conditions to sustain life.
Given all this information about the immensity of our universe, we feel that we are very small as compared to this wonderful universe. The recent photos on Wikipedia precisely clear our perspective about position of Earth in this huge and expanding space. The postion of Earth with respect to: the solar system , the Local Interstellar Cloud , the Milky Way , the galactic Local Group , the Virgo supercluster , the complex supercluster Fish Whale And finally … the observable universe.
We already knew that the universe is infinitely greater than the Earth . But these pictures provide us with an accurate picture about where our Earth is located in the universe. Does the universe size fascinates?
