From the article: "As the red giant tears apart nearby stars, the dense white giant absorbs the shrapnel, a mixture of hydrogen-rich materials that come its way. The tiny dead star then gradually becomes hotter until it reaches a breaking point when all that energy is released in a huge cosmic explosion — a so-called nova."
That's the worst explanation of a nova I've ever seen. You'd think the author would have at least glanced at the Wikipedia article about novae.
- febed 3y agoThe explanation isn’t good but they aren’t talking about a normal supernova here, it’s a recurring one that I too never heard about earlier.
- gus_massa 3y agoNitpicking: Don't confuse https://en.wikipedia.org/wiki/Nova https://en.wikipedia.org/wiki/Nova and https://en.wikipedia.org/wiki/Supernova https://en.wikipedia.org/wiki/Supernova From Wikipedia: > For other uses, see Nova (disambiguation), Novas (disambiguation), and Novae (disambiguation). > Not to be confused with luminous red nova, supernova, kilonova, or micronova. (Disclaimer: I have no idea what half of them mean, but I guess they are nasty things that can make a star brighter.)
