On Feb 14, 1990 NASA, by request of Carl Sagan, commanded the Voyager 1 spacecraft, having completed its primary mission and now leaving the solar system, to turn its camera around and to take a photograph of Earth... 4 billion miles away. In this image, Earth shows up as merely a "pale blue dot" seemingly drifting in a sunbeam (the first image in the video). The Earth is only 0.12 pixels wide in the original version of this image. The words being read are Carl Sagan's reflections on this image.

Anyone familiar ... ( 10 months ago by surferbeto)

Anyone familiar with basic principles of remote sensing understands that Greyhaven's patient explanation to SardonicusRexx is correct. A pixel is NOT "either on or off." A pixel represents a value of 0-255 in each of 3 or 4 bands. Bright objects much smaller than a pixel are detectable if they are viewed against a dark background because they color the whole pixel. SardonicusRexx's comments appear rather ignorant. I can't tell is he's just trolling or if he really doesn't get it.

For the memory of Carl Sagan! It's intended to make you reflect on how small we are in this universe, yet how much some people care about stupid crap so much.

I love the Pale Blue Dot concept, it's so utterly important. I'm an atheist but I attended church with my wife the other day and the pastor preached a sermon based on this photo. Unfortunately, he twisted it to stress how singularly important we are to the Christian God, that we are so small but so infinitely important to the Christian deity, and that we should give more money to the church accordingly. I nearly vomitted.
