390:. so you do not have any control over the angle of view or the distance and due to this you rarely get the opportunity to take a picture of titan. We do not have many options as this is the ONLY image that NASA has. Intensity in this colorized image is proportional to how much radar brightness is returned, or more specifically, the logarithm of the radar backscatter cross-section. The colors are not a representation of what the human eye would see. The lakes, darker than the surrounding terrain, are emphasized here by tinting regions of low backscatter in blue. Radar-brighter regions are shown in tan. The image is centered near 80 degrees north, 35 degrees west and is about 140 kilometers (84 miles) across. Smallest details in this image are about 500 meters (1,640 feet) across.

369:- False color suggests dirt and water, which would give the average viewer an inaccurate impression. Choice of angle is a bad idea: if you're not soing to show a true landscape, use an isomorphic (map) projection. Also needs distance key. I think the raw data could be turned into a FP, but whoever's running the post-processing for NASA went for "pretty" over "encyclopedic". —

look. Radar images taken by the spacecraft
Cassini during a fly-by of the moon on July 22nd last year show more than 75 large bodies of liquid ranging in diameter from three to 70km in the moon's northern hemisphere. It was taken by the Cassini spacecraft, and is a NASA public domain license. It currently appears in the Titan article
111:
perhaps not the most striking of images, but it is very encyclopedic, very informative, and very rare (due to contemporary technological limitations). The image is also technically flawless, being very large and without artifacts or noise. There are few pictures like this on
Knowledge (XXG); I think
280:
I think the picure is attractive, it's encyclopedic, difficult to reproduce and of high quality, the only thing that isn't so great is the blank space, which could perhaps be cropped out to give a smaller overall picture or be filled in as the research continues? Personally I think there is more

Scientists have uncovered evidence of the existence of lakes filled with liquid methane on Saturn's moon Titan. Although the existence of such lakes or oceans has been predicted for 20 years, this is the first time that convincing evidence has been gathered due to a dense haze preventing a closer
208:
But this is just a radar image, it could be anything anywhwere. There is no indication in the picture itself that this is a lighthour away or that we are seeing methane lakes. Don't get me wrong here, as a physicist I'm all for the excitement of the find, the pic on its own is what I find
218:
How exactly would a picture convey that it was taken a light hour away? We could of course create an animated gif that turns from black to image after an hour, but I don't think that's what you had in mind. ~
344:, we should see the macroimportance of this image rather than just the quality. It revealed the liquid methane lakes on the Titan, which nobody had seen before. It was important enough to on the COVER of

328:-- is this not one of the better pictures in Knowledge (XXG)? It is certainly more interesting than potatoes and coins, no matter how technical perfect those shots are.

Folks are ooh-ing and aah-ing over a
Photoshopped picture of a coin, but complain about a close-up image of an object a light hour away? Is this reverse week? ~

I tried to crop them out, but we'd lose too much of the picture. Plus they signal just how hard it is to take an image under these conditions. ~
