NASA space images for training algorithms are all fake - except one

NASA has revealed a stunning mosaic of fake space images used to train its astronomical algorithms – but has hidden within it is a single image of a genuine cosmic marvel. The mosaic below consists of 225 images, 224 of which are fake, created by artificial intelligence (AI). But one shows a real interstellar phenomenon, taken by NASA's Hubble Space Telescope. NASA uses computer algorithms to crunch digital images of the real night sky taken by robotic telescopes, in order to find stars and galaxies and measure their properties. This mosaic consists of 225 images, 224 of which are fake. One is real - but can you spot which one?
