Back in 2022, astronomers were puzzled by a so-called “tidal disruption event” (TDE), dubbed AT2018hyz, that had faded when it was first noticed three years earlier, only to unexpectedly reanimate and burp out extremely bright radio waves. University of Oregon astrophysicist Yvette Cendes, a co-author of that 2022 paper, dubbed the black hole “Jetty McJetface” (a nod to the 2016 online British competition to name a research vessel Boaty McBoatface).
