Greeting All,
I am quite new to the ISS forums and have been browsing through the Astronomy Science threads.
I thought many of you may be interested in my Uni's free on line encyclopedia of astronomy. SAO is within the Centre for Astrophysics and Super Computing at Swinburne University of Technology
It is an evolving resource, written by research astronomers and I am sure much of the information within this resource would help clarify many of your discussions.
