The cool thing about astronomy? It is also time travel! Did you know that when you look into the night sky your eye is being hit by the actual photons that were put forth by the stars you are looking at? We are connected to those stars through those photons, some of which have been traveling to us for many thousands of years. Look at a neighboring galaxy such as Andromeda and your eyes are connecting with particles that have traveled for 2.5 million years, 5.8 trillion miles each year, and they finally meet you and your eyes. How fantastic is that?
