Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled: "A Meteor and the Gegenschein." The meteor is fairly obvious in this picture taken near the Teide Observatory in the Canary Islands. But gegenschein? Notice the brighter 'spot' in the band of light extending from the upper left to the bottom center. That band is zodiacal light (sunlight backscattered by interplanetary dust). The bright spot is the gegenschein, or counterglow. It is also formed by the same interplanetary dust, but is seen at the point in the celestial sphere directly opposite the Sun from an observer's perspective (the anti-solar point).
German explorer Alexander von Humboldt coined the term "gegenschein" after observing the phenomenon during a trip to South America in the early 19th century. As you would expect, those of us living in a light-polluted world of technology don't often see gegenschein, let alone zodiacal light. But next time you find yourself unexpectedly beneath a dark sky, don't forget to look up.

Thank you my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) for Wednesday, May 12, 2021 entitled: "A Meteor and the Gegenschein."

APOD Background
"Explanation: Is the night sky darkest in the direction opposite the Sun? No. In fact, a rarely discernable faint glow known as the gegenschein (German for "counter glow") can be seen 180 degrees around from the Sun in an extremely dark sky. The gegenschein is sunlight back-scattered off small interplanetary dust particles. These dust particles are millimeter sized splinters from asteroids and orbit in the ecliptic plane of the planets. Pictured here from last March is one of the more spectacular pictures of the gegenschein yet taken. The deep exposure of an extremely dark sky over Teide Observatory in Spain's Canary Islands shows the gegenschein as part of extended zodiacal light. Notable background objects include a bright meteor (on the left), the Big Dipper (top right), and Polaris (far right). The meteor nearly points toward Mount Teide, Spain's highest mountain, while the Pyramid solar laboratory is visible on the right. During the day, a phenomenon like the gegenschein called the glory can be seen in reflecting air or clouds opposite the Sun from an airplane."

SSG Bill McCoy
Awesome Colonel - my music tastes are very eclectic - I enjoy big bands, jazz (especially mellow jazz), classical, 50's/60's R&R, C&W (not the Country Rock), and a lot more. Great post, as usual.

The meteor is acting like a candle to light up it's own part of the evening sky Maj William W. 'Bill' Price , have a great Wednesday sir.
