As we were introduced to some of the different types of objects we find in space and the first Messier Object in the previous article, Observing the Messier Objects (Part 1), this article continues with descriptions of more of the Messier Objects. We will concentrate on those objects that are deemed noteworthy with an attempt to include samples of all the different types. Messier 8 is commonly called the Lagoon Nebula, a diffuse nebula in the constellation Sagittarius. Giving rise to its name, a dark area appears to divide the cloud of glowing gas like a rift, but the dark area is actually dense thick gas and dust that blocks the light behind it, making it look like a gap. This star-rich region lies in the direction toward the plane of and central core of our galaxy, the Milky Way.
Messier (M) 11 is a beautiful rich sample of an open or galactic cluster, commonly called the Wild Duck Cluster. Located in the constellation Scutum, I recall my first telescopic observation of this cluster in 1969 and was impressed with a view rivaling a set of sparkling diamonds on a backdrop of black velvet. M13 is one of the brightest and richest globular clusters located in the constellation Hercules. Globulars appear like a splash of salt or sugar on a table top, with each crystal representing a star. A modest size telescope will easily separate, or resolve, the stars even in the dense core of this cluster. Nearby M13 toward the northeast in the same low power field of view is NGC (New General Catalog) 6207, a distant edge-on galaxy well beyond any star or object in our own Milky Way.
M16 is a star cluster and nebula in the constellation Serpens. This famous object has the common name of the Eagle Nebula due to some dense pillars of gas and dust lying near the heart of this object that resemble a flying eagle. The Hubble Space Telescope (HST) zoomed into this region capturing fantastic details of these pillars we call elephant trunks (for lack of a better term) and clearly showed us that near the top of at least one of them exists new stars in their embryonic stage of development. M17 is the Swan or Omega Nebula in Sagittarius. We often find that objects are called more than one name. Radiation from a local open star cluster causes the gases of the nebula to shine. Let's conclude this installment with M20, the Trifid Nebula. A diffuse nebula also in Sagittarius, its name comes from an appearance resembling 3 sections or lobes. But interestingly besides an open star cluster, the nebula itself is made of 3 kinds. A reflection nebula appears blue, an emission nebula appears red, and dark nebulae gives rise to its name. Many years ago, a former student of mine majoring in art gave me a beautiful painting of this incredibly colorful object.
