„As fun and creative as all three posters are, they’re based on real phenomena. In a dead galaxy, new star birth has ceased and most remaining stars are the long-lived variety, which are small and red, giving the galaxy a crimson glow. Likewise, when dead stars collide, they sometimes create a gamma ray burst, or the brightest type of explosion in the universe. And while dark matter may sound like it’s right out of a Halloween tale, its gravity keeps stars inside galaxies and hold groups of galaxies together in clusters – yet scientists don’t know what this invisible stuff is made of.“
