This week on Looking Up we are 'shielded' from ignorance about the constellation Scutum, thanks to Bruce Bookout.
The night sky contains many odd objects besides the menagerie of strange creatures. This time of year, in our southwestern sky, you will find a “shield” of stars. The shield is the constellation Scutum.
Scutum represents the coat of arms on the shield of John Sobieski, the king of Poland in the late 1600s. Sobieski is considered one of Poland’s great national heroes, where he stabilized and restored the Polish kingdom after countless years of devastation. As the Warrior King, he ensured victory over the Turks at the Battle of Vienna.
The noted stellar cartographer, Johannes Hevelius, first drew it around 1687, using a few stars from a relatively barren region of the sky. To honor his native country, Hevelius included the new constellation in his newest star atlas, which he published in 1690. He originally named it Scutum Sobiescianum - the shield of Sobieski. Of course, the last part of that names has been dropped in more recent times to keep it simply, Scutum.
Unfortunately, you need fairly dark skies to see it. Right now, look for it in the southwest as night falls. It’s above the teapot of Sagittarius. It’s only about four to five faint stars all somewhat in a line.
