Why stars can’t be trusted!
If you’re an astronomer you depend on accurate observations of stars, but there’s a problem. Stars are sneaky! Changing in size, brightness, color, they hide their chemistry, their age and even their companions from all but the cleverest observers. Stars explode precisely when they intend to. Betelgeuse took a brightness plunge, T CrB refused to go nova, and other failures to be predictable irk observers for good reasons. Let's talk about it.
