Three arches above Utah

This picture shows three different types of arches, two on Eath, and one not. The arch of our milky way can be seen next to the two arches made from sandstone. The type of galaxy that we live in is a type of spiral galaxy. Because of this, we can see the bands surrounding us in our night sky. These bands surrounding us are a part of the central disk. Millions of stars can also be seen in this picture. So manny can be seen because this picture was taken in the middle of the dessert where there is no other light to take away from the luminosity of the stars in the night sky. Such a view as this could not be seen in a light up city. The sand arches in this picture are formed by erosion of water agaisnt the rock. This breathtaking arch composed of sand is about 150 feet long, and about 90 feet tall.The dark objects that can be seen in the backround of the picture are actually monoliths that were formed in crevices on the floor of an ocean that evaporated millions of years ago. This stunning picture was taken in Utah, which is close to Colorado, which is where i was born! Since today is my birthday i thought i would add that in :)
