Microsoft has come out with a wonderful tool to explore the universe. It is called Worldwide Telescope and it is a web based program and will only run on Microsoft Windows.
Microsoft’s goal is to appeal to amateur astronomers, teachers and kids, people who might never get a chance to look at the Milky Way through a telescope as large and prestigious as the Hubble or the Chandra. This is a wonderful tool for homeschool families to implement your studies in the universe or astronomy.
