Pronounced skoo-tem, this constellation did not exist prior to the 1600s and is therefore considered modern. It was originally called Scutum Sobiescianum in honour of Polish warrior king John Sobieski. History When the Ottoman Empire tried to expand and take over Vienna, pope Innocent XI sent out a call for a 'holy league' of soldiers. This was answered by Sobieski, who was put in charge of a combined force of 70,000 men. This defeated an army twice its size. At the end of the battle the king was heard to say Veni, vidi, Deus vicit, which translates as 'I came, I saw, God conquered.' This battle was the beginning of the end to the threat posed to Europe by the Ottoman Empire. The founder of lunar topography, Johannes Hevelius (1611 - 87), delineated seven star formations in the 17th Century which are included in the 88 internationally recognised modern constellations: Scutum, Sextans, Vulpecula, Lynx, Leo Minor, Lacerta and Canes Venatici. They were introduced in his 1690 atlas Firmamentum Sobiescianum. When Hevelius drew up this star group it was the first modern constellation to be linked to a living person. Constellation Data
Formation of the Shield
Stars The system of naming the 24 brightest stars with Greek letters goes back to Johannes Bayer (1572 - 1625) and uses a Greek letter followed by the genitive (possessive) form of the constellation name. In 1862, Prussian astronomer Friedrich W Arlander (1799 - 1875) proposed that variable stars should have a new designation. This procedure assigns the first variable without a Greek letter the designation 'R'. This is followed by the next upper-case letters through to Z. Today, when these letters are exhausted, a two-letter name is used, starting with RR and going through to ZZ. Variable stars already bearing a Greek letter are not renamed, but keep their original designation. Star Table
Clusters and Nebulae There are two Messier catalogued objects in Scutum: M11 is the Wild Duck Cluster and M26. Both are open clusters.
Reflection Nebula IC 1287 The Reflection Nebula IC 1287 shines faintly, covering about 20' of arc within the rich star field near NGC 6649. Unlike emission nebulae, this type of cloud typically has a pale-blue sheen caused by the reflection and scattering of light by interstellar dust. Planetary Nebula IC 1295 The Planetary Nebula is situated near the globular cluster NGC 6712. Although ninth magnitude, it is a difficult target for backyard astronomers. Meteor Shower The June Scutids is a minor meteor shower whose existence was finally confirmed within the past 40 years. This low-rate display (up to four per hour if you are lucky) is active between 2 June and 29 July, peaking around 27 June.
