Our galaxy is about 100,000 light years across, so the stars you can see will not be that old. However, the Andromeda galaxy is round 2.9 million light years away, and is easily visible with the naked eye.

For objects a few billion years old you have to go to deep space telescopes.

You dont need a deep space telescope to see the earth or the moon ;)

I was talking about seeing them as they were a few billion years ago, like the deep space galaxy clusters! I can look at a rock on earth to see something a few billion years old.

In fact, I can look at just about anything, as the elementary particles are a few billion years old.

I wouldn't see a Higgs boson though.
