APOD: Sunset, Shadowrise (2010 Jul 29)

Postby APOD Robot » Thu Jul 29, 2010 4:05 am

Image Sunset, Shadowrise

Explanation: From central Australia, this serene 360 degree panorama follows a clear horizon as twilight began on May 28. At left, a bright western sky is still illuminated by the setting Sun. But sweeping right, toward a view centered on the countryside's dominating sandstone formation called Uluru or Ayers Rock, the sky takes on progressively darker hues and subtle colors. Behind Uluru is the shadow of planet Earth itself, a dark blue arch rising in the east. Cast through the dense atmosphere and still close to the horizon, Earth's long shadow is bounded above by a pinkish glow or antitwilight arch. Known as the Belt of Venus, the lovely color of the antitwilight arch is due to backscattering of reddened light from the setting Sun. On that night, a nearly full Moon also rose above Earth's shadow in the eastern sky.

What a beautiful image!

This is a perfect illustration of my contention that night doesn't fall, it rises.

And in the morning it sinks! :mrgreen:

I once saw a nearly full Moon sit smack in the middle of the Earth's shadow one early morning. The blue shadow looked like thick distant fog or an opaque cloud bank. It seemed impossible that the Moon could be seen right through this thick-looking blueness, yet there it was, clear as day.

That'd be a lunar eclipse, wouldn't it?

Thanks for the nostalgia Art!
I liked the center of the photo best; with the tree and Ayers Rock. 8-) Don't get me wrong I liked the whole panorama. :) I presume that lone dot of light was Venus?

True; but it isn't on the panorama. :? It does give a link to another panorama that shows Luna.

True; but it isn't on the panorama. :?

:oops: I didn't expect it to show up that small. It does say above the Earth's shadow.

I see this nearly every month, and how close the Moon is to the terminator is a clue to how near we were to an eclipse.

On which projects the shadow of the earth? I think about the atmosphere itself and which forms the belt of venus? I think about the atmosphere itself with the color of sunlight at the surface through the stains of that color. I hope to rectify if different.

So that's what it's like to have eyes in the back of your head to see through at the same time you are looking forward. Amazing!!
