Astronomy Tools: Observatories and Virtual Observatories

One of the greatest on-earth tools astronomers have is the observatory--a place that usually houses a giant telescope and other tools useful for observing the sky.

Now the internet makes it possible for anyone to access the information collected by observatories in Virtual Observatories.
