I don't know the instrument--but that sort of thing is frequently due to a double reflection within a window that separates the fore-optics from the outside universe. Depending on the material (silica, sapphire, ...) you get a significant fall-off for a double reflection, and then the same fall-off to quad, etc.

...There is a ghost image of Earth about three diameters to the right of the actual image...
There is also a ghost image the same distance to the left.

Good catch! It is indeed the Neogene-Miocene period as the last step in the animated gif. The work that Stu originally referred to was done in collaboration by Dr. Ron Blakely of Northern Arizona University. (The animations in the wikipedia entry were done by Dr. Ron Blakely.)

Here is his website that has individual maps of each of the paleo-reconstructions (including Pleistocene and Present) :
http://jan.ucc.nau.edu/~rcb7/mollglobe.html

And a website to other detailed data products:
http://cpgeosystems.com/index.html


I recently got a copy of his (beautifully illustrated) book: "Ancient Landscapes of the Colorado Plateau", mentioned on his site. I highly recommend it.


Yes, this is a good dataset. We've used a smoother version of this animation in Science On A Sphere.

A frame exists for the future projection of the continents. I've considering making an augmented version of the animation that incorporates this into the future.

Here's a colorization of this LRO Earth image. Below is a preview at 10% resolution, 1/2 res version is available here (2.3 MB) and full res version here (8 MB).

Very lovely, except for the Photoshop masking artifacts around the edge (mainly in the 12 o'clock to 2 o'clock positions).

The NPP mission is making a Global Image (not just hemispherical) of the Earth every day. Here is the first image release:

Rosetta Earth flyby 2 revisited, magnified 1.5x from original scale and rotated so north is up:


This one was hard to work with. The red and especially the green channel suffers from a ghost image which makes the composite look ugly. I tried subtracting them out as best as I could but it still left residual images of the bright clouds in the green channel. As a result, fair portions of the sea and cloud areas use synthetic green while most of the land masses use RGB colorm as synthetic green doesn't produce satisfactory color.

I abandoned the very same data set for the reasons you mention.... GREAT work.

Updating this post - the animation for past continental drift has moved to here: http://sos.noaa.gov/Datasets/dataset.php?id=336

And I've been putting together a future projection animation, from some of Ron Blakey's future frames:
