APOD: Comet, Heart and Soul (2018 Aug 23)

Post by APOD Robot » Thu Aug 23, 2018 4:07 am

Image Comet, Heart and Soul

Explanation: The greenish coma of comet 21P/Giacobini-Zinner stands out at the left of this telephoto skyscape spanning over 10 degrees toward the northern constellations Cassiopeia and Perseus. Captured on August 17, the periodic comet is the known parent body of the upcoming Draconid meteor shower. Predicted to be at its brightest next month, the comet is actually in the foreground of the rich starfield, only about 4 light-minutes from our fair planet. Giacobini-Zinner should remain too faint for your eye to see though, like the colorful Heart and Soul nebulae near the center of the sensitive digital camera's field of view. But the pair of open star clusters at the right, h and Chi Persei, could just be seen by the unaided eye from dark locations. The Heart and Soul nebulae with their own embedded clusters of young stars a million or so years old, are each over 200 light-years across and 6 to 7 thousand light-years away. They are part of a large, active star forming complex sprawling along the Perseus spiral arm of our Milky Way Galaxy. Also known as the Double Cluster, h and Chi Persei</a> are located at about that same distance. Periodic Giacobini-Zinner was visited by a spacecraft from Earth when the repurposed International Cometary Explorer passed through its tail in September 1985.

Interesting the contrast of this and the other recent image of the Heart....

Beautiful indeed.

However, a contributor to the Recent Submissions thread, PauLee97, recently posted a picture showing much the same motif, but personally I like his colors even better. Also, he captured a meteor seeming shooting at the "gap" between the Heart and the Soul Nebulas. Check it out!

I like the image, but always find it jarring to see an enhanced image of objects “near” something familiar (the double cluster, of course) looking about the way it looks through a pair of binoculars. I understand the reasons; I like muted colors, but then you couldn’t see much structure.

Pardon me dipping my toe in the water, but I’ve long found these discussions as interesting, or often more so, as the images.
