Where do we observe cosmic background radiation?
Josiah AdamsEvery where in the universe.
The probes are sent far from Earth because the signal is faint, so they are not affected by Earthly electromagnetism.

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.
