I was watching a program on TV this morning about astro physics. In one part they were talking about the size of our galaxy and went on to say ‘Here is a photograph of our galaxy’. Surely it cant be a photograph, it must be a digital impression of what we think it looks like?
How do scientist know what it looks like? Voyager 1 is the farthest man made object but she hasn’t left our galaxy has she?
