This article presupposes that Proxima Centauri is not, in fact, made of chorizo. Whereas we have long known that the moon is made of cheese. I think Klein is floating a test balloon to gauge the public's willingness to consume the 'celestial charcuterie' theory of the heavens.
Speaking for the food producers of Earth and the Solar System, I object to calling whatever material this extra-solar planet is made of "chorizo". If some expedition were to be made to this planet and return a thousand years later with a 10,000 km long sausage (nicely preserved due to the vacuum I suppose), it should not be be able to confuse the consumers by selling it under a brand name connected with Earth sausage…
Fine... we'll call it Sparkling Pork Sausage.
