November 14 2016 Astronomy Newsletter


Hi everybody

Here's the latest article from the Astronomy site at BellaOnline.com.

Scutum the Shield
Vienna, September 1683. For two months the city had been besieged by an army of the Ottoman Empire, and couldn't hold out much longer. But what does this have to do with astronomy? The link is the constellation Scutum (the Shield).

And here's the previous article. I was traveling and in the excitement didn't get the newsletter written.

*Birthdays galore*
