Astronomy Picture of the Day -- Three Arches Above Utah
NASA ^ | May 24, 2011 | (see photo credit)

Posted on 05/23/2011 9:23:11 PM PDT by SunkenCiv

[Credit & Copyright: Brad Goldpaint (Goldpaint Photography)] Explanation: How many arches can you count in the above image? If you count both spans of the Double Arch in the Arches National Park in Utah, USA, then two. But since the above image was taken during a clear dark night, it caught a photogenic third arch far in the distance -- that of the overreaching Milky Way Galaxy. Because we are situated in the midst of the spiral Milky Way Galaxy, the band of the central disk appears all around us. The sandstone arches of the Double Arch were formed from the erosion of falling water. The larger arch rises over 30 meters above the surrounding salt bed and spans close to 50 meters across. The dark silhouettes across the image bottom are sandstone monoliths left over from silt-filled crevices in an evaporated 300 million year old salty sea. A dim flow created by light pollution from Moab, Utah can also be seen in the distance.

I'm glad APoD's in my time zone, I'm able to take care of the 24th now. I plan to take it easy tomorrow, weaning myself off the www for the summer. Heard that one before, haven't we?

the smaller one has a kind of 3-D quality, so I thought a larger size would be nice on the drive.

check it out, doesn’t that “rock” foreground look fake?

Probably a short time exposure for the stars, and then a flash exposure of the arch, with the same camera setting.

I remember camping out in the canyonlands and just being awed by the stars. It was incredible Same with the Mojave desert. If I could get rid of my house without losing a small fortune, I’d sell everything and move out there without hesitation. Utah was just incredible. I’m sure I’ll end up living there some day.

And to think, that 300 million years ago, when that was the bottom of a sea, the stars were actually where we see them today.

Here's a clip from the photo matched with my Starry Night view from a Utah location ( Salt Lake City - close enough for this purpose )

The "red" star is Antares in Scorpio. The red lines in the star chart are hour lines and latitude lines. The hour lines are 30 minutes apart here, so you can see the exposure was maybe a minute or tow long to produce the trails that we see. ( I can get a better estimate by blowing up the scale. )

More than a little imprecise.

Yeah, aren’t we out in some backwater spiral arm?

And as you can see, we’re in a backwater spiral arm (”...the Orion arm is not a major spiral arm, but only an enhancement of stars and gas between the Sagittarius and Perseus arms”).

Hundreds of Billions of miles at blinding speeds beyond comprehension.

BUT.... from our perspective...

Well, it's like having beachfront property. You get a nice view, and it's way away from the crowded (and very hot) inner city.

Away from the (very hot and possibly containing a black hole) inner city is always a plus.

Actually, the stars are just holes in the celestial canopy. ;’)
