The next generation of ground-based telescopes are coming to give us an unprecedented view into the cosmos. Today, the Giant Magellan Telescope was approved to begin construction in Chile. When it opens its eyes in 2021, it will be the largest telescope in the world ... for a little while, anyway. The building of the GMT marks the beginning of the era of extremely large telescopesâthose whose light-gathering surfaces measure in excess of 80 feet. The Giant Magellan will measure just over 80 feet.
How far can I see with a telescope? Pretty far. Usually this question is asked when comparing two scopes, as in can I see farther with this telescope?. A bigger scope will show you more, but not necessarily farther. You don't really need to see farther, though. With the unaided eye, you can see 2.8 million light-years to the Andromeda Galaxy. Even a very small telescope can show you an object called 3C273, a quasar in Virgo that is 3 billion light-years distant. But most objects that are interesting to look at aren't that far away. What you really want with a telescope is light-gathering power to see fainter things, not farther things.
