They can make color images out of the individual black and white images, but they also get accurate measurements of how bright things are in each color. In addition, special color filters can isolate colors that are absorbed by methane in the atmosphere of Saturn and Titan and show otherwise invisible details. In this case though, the camera was using a clear filter and it doesn't look like they took any colored filter images in this particular sequence. The scientists may be interested in high resolution imaging of the small moon, or of something too dim to see with the filters on, or they want to make a movie out of the images. It's hard to say without asking them. <a HREF="http://saturn.jpl.nasa.gov/faq/raw-images.cfm" rel="nofollow">Common questions about the raw images can be answered here</a>. Hi Sohn-

This is an amazing program. And there is a big community (and a dedicated website) for better add-ons and textures. Just check out their screenshot gallery... http://www.shatters.net/celestia/gallery.html</a> Have fun! For those of you who can’t wait for their turn in touring space should try out Celesita .

(or they pictured the image in the range of the frequency of non-visible light?) And I wonder that how they give colors to the image as well. Why doesn’t this image have colors?

It amazes me that nature seems to "repeat" his/herself across such a large scale.
