RELATED TOPICS: HUBBLE TELESCOPE
Astronomers' Milky Way model
We say that a telescope looks back in time when it looks into space, but that is not exactly true. Light takes some amount of time to travel from one object to another; it is not instantaneous. Light covers 186,282 miles (299,792 kilometers) each second.
