Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Messier 20 and 21." Also known as NGC 6514, the Trifid Nebula (Messier 20, left) was first recorded by Charles Messier in 1764. It illustrates three different types of astronomical nebulae; red emission nebulae dominated by light from hydrogen atoms, blue reflection nebulae produced by dust reflecting starlight, and dark nebulae where dense dust clouds appear in silhouette. Messier 21 (right), also recorded Messier in 1764, is an open cluster of stars that is relatively young and tightly packed. Both are located in the constellation Sagittarius, and are visible with a pair of binoculars or small telescope. Both lie approximately 5,000 light years away, but their ages are significantly different: M20 is about 300,000 years old, while M21 is 8 million years old.

Thank you my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) for Thursday, August 6, 2020 entitled "Messier 20 and 21." Also known as NGC 6514, the Trifid Nebula (Messier 20, left) was first recorded by Charles Messier in 1764.

Spectacular picture of the LORD's creation in the heavens.
Explanation: The beautiful Trifid Nebula, also known as Messier 20, is easy to find with a small telescope in the nebula rich constellation Sagittarius. About 5,000 light-years away, the colorful study in cosmic contrasts shares this well-composed, nearly 1 degree wide field with open star cluster Messier 21 (right). Trisected by dust lanes the Trifid itself is about 40 light-years across and a mere 300,000 years old. That makes it one of the youngest star forming regions in our sky, with newborn and embryonic stars embedded in its natal dust and gas clouds. Estimates of the distance to open star cluster M21 are similar to M20's, but though they share this gorgeous telescopic skyscape there is no apparent connection between the two. In fact, M21's stars are much older, about 8 million years old.

The Trifid nebula, a region in our Milky Way, is an unusual combination of three spacial events. The young energy field is constantly in motion and can be seen from Earth as a colourful and bright phenomenon. The music of TRIFID came into existence because three musicians felt the urge to explore and discover the unique fusion of accordion, vibraphone and double bass. The result is an exciting and intense perspective of something which can be described best as a spirited, yet serene and intimate, energy field full of lyricism and mystery.
