EbylHusker Posted August 30, 2013 Share Posted August 30, 2013 It's an interesting theory, but one that makes a lot of assumptions and interpretations of things that favor this certain theory, while ignoring others. That's nothing against this theory, though, since all theories on the origin of life on this planet do just that. What a lot of people don't understand, unfortunately, is that most of these types of things are riddled with assumptions and interpretations that are crafted to intentionally favor the researcher's pet theory.

ZRod Posted September 4, 2013 Share Posted September 4, 2013 Anybody know if these images are still colored in or are we are seeing the real colors these days? I'm too lazy/busy to look it up right now. I know the Nebula's and such are, but I didn't know if images from newer satellites were or not. Quote Link to comment

I'm too lazy/busy to look it up right now. I know the Nebula's and such are, but I didn't know if images from newer satellites were or not. I'm not sure. Hubble, for instance, doesn't actually take color pictures, but has filters that only allow certain wavelengths of light through. By analyzing and combining data from different wavelengths, and assigning colors to wavelengths, color images are produced. Cassini's cameras work in a similar fashion. That said, this method does allow them to produce "accurate" colors as they believe you'd see if you were actually there viewing it. Quote Link to comment

I've always wonder if the images were totally accurate though, and not over saturated or what have you. I wish they were able to take a "true" picture instead of putting composites together from the different spectrum. Quote Link to comment
EbylHusker Posted September 5, 2013 Share Posted September 5, 2013 Well, what you get out of a DSLR isn't really a "true" picture in terms of what the human eye sees (and more to the point, what the brain perceives). So whether you've got a conventional RGB sensor that records the data in that way, or are using filters and then compositing wavelength band pictures, the end result is still pretty much the same. As for bumping in saturation, contrast, etc, I'm sure many are. But you'd probably have to find comments about each specific image to know for sure. 1 Quote Link to comment

tschu Posted September 11, 2013 Share Posted September 11, 2013 I'm so pumped for Comet Ison aka C/2012 S1. I might be setting myself up for a massive disappointment, but I still remember watching comet Hale-Bopp in '97, looking out west from our driveway into the evening sky. For weeks! If only I was old enough to appreciate what I was seeing - an incredible comet event that might never occur in my lifetime again. Come November and onwards, we'll find out if the comet will amaze us or fizzle and disappoint us. I want to believe.... Quote Link to comment
