How did astronomers find the next nearest galaxy?
The nearest Galaxy to milky way is a naked eye object.
The Andromeda galaxy can be seen with the naked eye. At first, it was believed to be a nebula, but stars had to be resolved using a large telescope in order to determine that it was, in fact, a spiral galaxy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
