I clicked on the question to post my view on this article. It mentioned a star call T Pyxidius, and that with a companion star goes to nova every so many years. The article also said it was very dim with a magnitude of 14, but brigthens to about 6.2, before fading back to normal. What I want to know is, that when they talk about such events? Why don't ever talk about how many light years away from us these stars are? Like this article stated that the last time this star T Pyxidis last went nova was over 40 years ago. Don't they mean that it went nova more than 40,000 years ago or however far away T Pyxidis actually is?
