They say that space really is the final frontier and the media, probably even more so than the scientists. In this infographic you will find out, exactly how much money both these little odysses into the unknown are costing us.
For more than a decade, scientists have observed “ship tracks” in natural-color satellite imagery of the ocean. These bright, linear trails are a visible manifestation of pollution from ship exhaust, and scientists can now see that ships have a more subtle, almost invisible, signature as well.
