It is so vast that, according to some, the light won’t reach from one end to another within the age of the universe. However, scientists are still engaged in research to solve the mysteries of space. However, no scientific instruments have been manufactured to date to calculate the vastness of space and university accurately. The Hubble space telescope has enhanced the capacity of human visibility to 94 billion light-years. This artificial space object is working as an observatory in the sky. The Hubble space telescope is known as the first major optical telescope developed by NASA and launched three decades earlier. It orbits the earth and provides outstanding pictures of space that are considered the most important images to enhance human knowledge and insights into space.
