“We sent whalesong into interstellar space because the creatures that sing these songs are superlative beings that fill us with awe, terror, and affection. We have hunted them for thousands of years and scratched them into our mythologies and iconography. Their bones frame the archways of medieval castles. They’re so compelling that we imagine aliens might find them interesting — or perhaps understand their otherworldly, ethereal song.”

― Nick Pyenson, Spying on Whales: The Past, Present, and Future of Earth's Most Awesome Creatures
