Since this image has proven popular (some 190,000 hits last month alone), here’s something in the same vein. The first photo of Earth taken from another planet, in this case taken from Mars by Spirit on March 8th 2004.
Some things to consider. I will not necessarily be responding to (or even reading) comments. I generally do not block comments unless they are off-topic, merely a soap-box for the individual, or clearly spam. I reserve the right to ban persistent offenders. Occasionally a comment will be held up for moderation because it triggers a filter; in particular comments with four or more links will be delayed. Do not resubmit the comment - it will be posted when I get an opportunity. Lastly, commenting get automatically shut down three weeks after the post first appears. Have fun!
