Throughout time, humans have explored their surroundings, crossing oceans and landmasses in pursuit of knowledge and glory. This thirst for knowledge also turned eyes skyward, causing the curious to try to understand the vastness of existence around the planet Earth. As technology advanced, the desire to venture into the cosmos became increasingly possible, until man walked on the moon and equipment traveled much farther away. Fortunately for those who are still on terra firma, gathering information about the universe is much easier than launching on a rocket ship. People can learn and discover more about deep space through adventures in cyberspace without the need for oxygen tanks or special suits.
