A Visual Guide to the Universe with the Smithsonian
This is the general description of the course/series.
For the first time in human history, we can see the full splendor and mystery of the universe, thanks to instruments on scores of planetary probes and observatories that have been launched into space since the 1990s.

Episode 9 The Seven Sisters and Their Stardust Veil
I really liked Episode 1 as it starts to describe Stonehenge and importance of tracking the motions of the sun to its northern and southern extremes at the solstices for tracking the seasons, and thus why building alignments to determine this were important.
The Pleiades cluster, or Seven Sisters, is one of the most beautiful star formations in the heavens. Discover the origin of the wispy nebulae that surround these bright stars. In the process, learn how the Hertzsprung-Russell diagram is a powerful tool for estimating the ages of star clusters.
Episode 10 Future Supernova, Eta Carinae
This episode was pretty good, including an in-depth discussion of the various theories on the possible alignments at the henge, which are of interest to me particularly because my brother-in-law grew up very near Stonehenge.
