50 Years after Yuri Gagarin's space flight and about 40 years since I studied a bit of Astronomy I am taking an Astronomy course. The lectures are given by a retired Astrophysicist at a local Senior Center.

I am amazed how much has changed. We know much more about the Universe than before and at the same time all is in flux and new information is expanding rapidly. (not unlike the Universe itself)

Below I am providing links to an incredible NASA site that contains a calendar of new Astronomy related images published every day. (Astronomy Picture of the Day)
