Bloop? Or blooper?

On Tuesday’s Astronomy Picture of the Day, the image shown above is described as a visual representation of the loudest sound ever detected in the ocean by underwater microphones. Called a bloop, it is even louder than the sounds that can be made by giant blue whales. My first question is: What does this have to do with astronomy? My second question is: Who do they think they’re fooling?

After careful study, I’ve determined that the above picture is of brightly-lit skyscrapers in Chicago reflected in Lake Michigan, taken with a cheesy cheapo digital camera with its ISO setting way too high. Prove it to yourself by backing away from your computer screen about 15 feet (5 meters). I’m sure you’ll agree.
