Prominent physicist Étienne Klein is apologizing for his Twitter prank, admitting the photo of a distant star he posted was actually just a slice of chorizo sausage. Klein had posted the pic, writing "Picture of Proxima Centauri, the nearest star to the Sun, located 4.2 light years away from us. It was taken by the James Webb Space Telescope. This level of detail... A new world is unveiled every day." The picture was liked and retweeted thousands of times before Klein admitted that the detailed pic was actually just some chorizo sliced up in front of a black background. He revealed the nature of his prank; to warn others about fake news online.
