Google Earth has launched a new facility - allowing users to "time travel" virtually - through ancient Rome. Google Earth affords on line travelers an opportunity to visit the street where they live. Now they can also travel back to an era 17-hundred years in the past.

Google Earth is the popular mapping service that lets users move through three-dimensional satellite images showing city streets. Now users will also have a chance to "time travel." Google Earth's newest attraction allows virtual visits to ancient Rome, around the year 320 AD.
