BEYOND DEEP SPACE
From neutrinos produced just seconds after the Big Bang to the most distant superclusters of galaxies we know of, studying the edge of our universe is an exciting task for astronomers around the world. And thanks to advancements in technology, we know more than ever about what lies at the boundaries of our cosmos.
When you look at something, you are looking back in time. This holds true for anything you see, it’s just the distances involved are mostly so small and light moves so quickly, you will never notice the time it takes to reach you. When you begin to look into space, the time difference starts to matter. Looking at the Moon, you are seeing it about 1.3 seconds back in time. Light takes just over eight minutes to reach us from the Sun, and to Jupiter it’s about 43 minutes.
However, these kinds of time scales are nothing compared to the amount of time it’s taken light to reach Earth from the most distant stars and galaxies we can see.
Based on calculations, astronomers believe the universe is 13.8 billion years old. Light moves at the speed of
