"Stars On A Trail"

A Path North
* Image Credit & Copyright: Mario Konang

Explanation:
What happens if you keep going north? The direction north on the Earth, the place on your horizon below the northern spin pole of the Earth -- around which other stars appear to slowly swirl, will remain the same. This spin-pole-of-the-north will never move from its fixed location on the sky -- night or day -- and its height will always match your latitude. The further north you go, the higher the north spin pole will appear. Eventually, if you can reach the Earth's North Pole, the stars will circle a point directly over your head. Pictured, a four-hour long stack of images shows stars trailing in circles around this north celestial pole. The bright star near the north celestial pole is Polaris, known as the North Star. The bright path was created by the astrophotographer's headlamp as he zigzagged up a hill just over a week ago in Lower Saxony, Germany. The astrophotographer can be seen, at times, in shadow. Actually, the Earth has two spin poles -- and much the same would happen if you started below the Earth's equator and went south.

"Stars On A Trail"

Please click the post above to reveal the whole path of that thread.

This thread about Star Trails is a long trip through the photo archives of NASA and ESA. Some of you have already seen my affinity for these archives, and in threads like this one I would like to make you understand my fascination. So if you like, follow me this time on my trail in all directions back and forward in time, past beautiful, special, extreme and even magical places, through a gallery of wonderful images, provided by great often volunteer astrophotographers who are generous enough to share their love and fascination for the stars around us ..

Please visit their websites, leave friendly and encouraging comments and maybe you will even have the opportunity to support them financially or logistically. On each of my posts you can find a link to the archive pages and many of the astrophotographers leave a link there or even a mail-address

I can hardly express my great gratitude for all the magic and beauty and I sincerely hope that these archives will be available to us for a long time to come! But you never know, with the power-obsessed destructive Lunatics these days..

Anyway, I really hope you enjoy this trail with me.

grobi wears a new hat with an US-shaped Pride flag embroidery and a peace sign, as well as new "John Lennon" sunglasses reflecting a well-known Planetary Nebula .. He rides the wrong way around on a laughing horse through space, accompanied by Hubble and Chandra, in the background you can see Gravity's Grin or flippantly called the Cheshire Cat galaxy group. grobi looks kind of stoned, but swears stone and bone that he has not ingested any external toxic materials. Instead, he mumbles something about Dark Matter and the distortion of the time-space continuum and that he now has more foresight.. .. and on top of all this, does he invite us on a journey through space and time??? Honestly, he had the wrong mushrooms in his lunch soup, didn't he?
