The Cosmos: Create a Spiral Galaxy. A galaxy is a massive collection of stars, stellar remains, gas, dust, and planets.
Galaxies can contain as few as 10 million stars, or as many as 100 trillion. Astronomers believe that there are about 170 billion galaxies in our universe, each varying in shape from spiral, elliptical, to irregular. In today’s tutorial, we will demonstrate how to create a spiral galaxy of your own and will depict a fleet of ships making its way through the universe to find a new home. The Cosmos: Create a Green Planet, a Setting Sun, and a Space Ship in Photoshop.
Our universe is vast.
So vast, in fact, that astronomers don’t measure its size in meters or miles but by explaining how long it would take to travel a certain distance at the speed of light. Light travels approximately 186,282 miles per second. This means that in a one year a person traveling at the speed of light would travel about 6 trillion miles. In today’s tutorial, we will be concluding our cosmos series by demonstrating how to create a green planet, a setting sun, and a space ship which has traveled several million light years in Photoshop. Today's tutorial is part of a 4-part series depicting the journey of the inhabitance of a dying world that must travel into the unknown to find a new world to call home.
