Re: Reverse sun motion
It takes about 4 hours and 45 minutes to fly from Tampa to LAX so If you left Tampa at 9am local (6am LAX) when you landed at LAX it would be 10:45 local so the Sun would be 1h 45m further along it's path through the daytime sky When you land at LAX Local time will be 1hr 45min later than when you l...

Re: Reverse sun motion
The other aspect is, LAX is at 33d 56'N and Tampa is at 27d 58'N
almost exactly 6d further south and would also cause the sun to appear a little further south in the sky at LAX

Re: APOD: Dark Sand Cascades on Mars (2015 Nov 29)
The image makes more sense rotated 180 degrees because it makes the downhill streaks run toward the bottom. But why are all the streaks on the same side of every dune? Did not one slip the other way? And why are the streaks black when all the other material on both sides of the dunes is light? I'm ...

http://s.hswstatic.com/gif/sand-dune-6.jpg What I believe we are seeing is: The ridge line, where the wind blown upslope meets the angle of repose, is where the dark streaks begin at the ridge line and flow down the repose side branching slightly at the bottom The even side is the top of the slope ...

Re: Moon orientation across sky
When you face East, the point that represents North is located NW of E. When you face West, the point that represents North is located NE of W. This difference in the respective perceived North causes the apparent shift in the Lunar North. The rotation is gradual as at any given point in the Lunar p...

Re: Moon orientation across sky
this is similar to the orientation of Orion. At my latitude, 38deg N, Orion rises on his back like waking up after sleeping, and sets on his feet.
In the eastern sky, the Pleiades rises first then Taurus then Orion awakes.
In the Western sky, Orion's feet set first followed by Taurus then the Pleiades

Re: APOD: Phobos: Doomed Moon of Mars (2015 Nov 22)
« Gravitational tidal forces are dragging it down. » That assertion is puzzling... The mean distance between Mars and Phobos is 9377 kilometers , whereas the mean difference between the Earth and the Moon is 384,400 kilometers . That means that Phobos is ~40 times closer to Mars than the Moon is to...

You're probably right about that. He quite likely would claim that you only identified 899 instead of 900 out of 1000 and won't be considered as successful

Any Math Geeks wanna earn $100,000
Doug Keenan has posted a challenge... Anyone that can accurately identify at least 90% of the 1000 series' as trended or not trended, and is willing to pay $10 US to find out if they did or not, will be given the sum of $100,000 US if successful. I'll wager he is banking on having at least 10,000 en...

Re: Cute stuff goes here; you have been warned!
Looks like Geck is correct. I found it on a Google search for baby polar bears and found it just too adorable
Apparently this is what a baby polar bear looks like at that point

Although I can't open the photo information my Kindle, this looks like it would be about a 5 second exposure. Your eye processes light in 1/30th second and so the locale wouldn't appear as depicted in the image to your eyes if you were standing there. But with the camera iris open for 5 seconds, the...
