Wandering Universe

Episode 26 of Wandering Universe.  Another short episode this time. Since we're on the subject of summer, this show focuses on one of the season's most plentiful objects; globular clusters.  What are they?  News niblet about LIGO and the What's Up segment round out this last 2x monthly episode.  From now on Wandering Universe will be a monthly show, coming out in the first week of the month.
