2022 Supernova Boneyard
Welcome to the Boneyard. On this page you will find entries for objects that have been confirmed as Cataclysmic variables, asteriods (otherwise known as Vermin of the sky), or some other non extragalactic event. Why keep them around? Because you never know when something like this will come back to life...
