How many parsecs of space have been mapped so far?

Question

Is there a site where I can download a 4D map of the known stars, galaxies and rate of expansion of space?

Answer 1

A parsec is a measure of distance, not volume.

1 parsec = 3.2616 light years

You can fit an infinite number of distance measurements in any finite volume, so I'd have to answer with "infinity".

To answer your second question, here's a good website:

Answer 2

In Discover magazine, I read a story that in 2006, astronomers have the most complete map of the "local" universe - all objects within about 600 million light years.
