Got more stay at home time than you know what to do with? Do you want to experience the joy of learning and gaining knowledge in science and astronomy? Well I have a suggestion for you! Take an on-line course. I did and it was a great learning experience.

The course was free from Coursera.com and titled " Astronomy: Exploring Time and Space". It consists of a series of videos lectures from Professor Chris Impey at the University of Arizona, and included companion on-line readings and presentation slides.  The description says it takes 59 hours to complete, however it took me a little longer.  Also, included in the course are tests in each chapter, essay assignments graded by fellow students, and regular bi-weekly live Question and Answer sessions with Professor Impey.  Did I mention that it is all free?

If you are looking for a course on how to use a telescope, then this is not the course for you.  However, if you want take a look into Scientific Methods, Our Solar System, The Life Cycle of Stars, Tools of Astronomy, Astrophysics, Theory of Relativity, Exoplanets and more, then I highly recommend this course. 

My only negative is that some of the accompanying video segments (not the lectures) were geared to a different generation of students, so I just skipped them.  

The good news is that if this course does not sound like a good match for you there are over 1400 other classes on Coursera.com that are free. I found the regular routine of the class structure and the stimulation of learning new ideas were just the thing for me - and I think you will too.
