why an alien ship?
I was trying to find out what picturing mechanism would give you those perfectly aligned lines (from one pic to the next one)
It turns out NONE! they just combined some of them to one picture without expressively pointing that out.
This finally explains why those streaks were so nicely aligned from one picture to the next one.

Will,

three separate exposures would look like this, yes.
This link explains it quite well:

here's one of the pictures taken on that day:
http://hla.stsci.edu/cgi-bin/display?im ... WFC3+F606W

drag a little bit to the top to see the comet.
This interactive image viewer lets you use gamma control on the raw data by letting you push on the "darker" and "brighter" button on top.

try it out.


The image is the result of combining 3 exposures that produce the 3 components, and the shapes are produced by the combined motion of the Hubble telescope and the comet.

That image (shown above) is the average of 3 separate Hubble exposures. The 3 exposures are available individually for display or download from the web page, as is the combined image.

There's 8 pictures of the comet that are taken on the same day.
If you align those 8 pictures you get the weirdest thing ever!
It looks like a huge triangular object that turns on and off parts of its edges.
As the position of those lit edges stays the same, even when they're turned off and later turned on, I can't imagine how this could be explained with long exposure and stacking.

I just made this gif, so it's a DTV exclusive :D

it's wider than 750 pixels, so you have to click on the link:

Prove it! Where is the link to the original images you used?
Not here...

the original images from that date were darkened to get that strange image inside the white mesh of the comet. you can get the original hubble image, darken it a few shades, and you will see

Thank you Tjahzi!
as soon as there's new pictures available from Hubble, we will know if those strange images are because of the way Hubble's wide field camera works or not.

As I don't have access to telling Hubble what to take pictures of, all we can do now is wait! :D

I'm not entirely convinced by that link.
