The NASA public archives present a vast resource of authentic satellite data that research astronomers have tapped into for decades. Recently, the same data analysis tools used by professional astronomers have been adapted into a browser-based interface called JS9 for easy use by any interested student. Tutorials and classroom-ready activities that explore many deep sky objects in depth have also been generated. JS9 affords a unique, platform-independent introduction to the world of astronomical observation with no cost to anyone. It presents a virtual-classroom-ready approach that can be utilized anywhere, at any time, at home or anywhere that internet connectivity is available. Its predecessor, DS9, is still used extensively and is available as a desktop application.
