Such heavy loads of dust are generally thought to arise much later in cosmic history than circa 400 million years after the big bang, the epoch at which this newfound galaxy appears.Although the work has yet to be peer-reviewed, a preprint study that analyzed this “red monster” galaxy, officially called EGS-z11-R0, is already making waves in the astronomical community. “It’s astonishing to think about how short these timescales are,” says Pieter van Dokkum, an astrophysicist at Yale University, who was not involved in the study. “Sharks and turtles have been around for about that long.”For perspective, seeing such a big, dusty galaxy
