* Higher Mass: Blue stars are much more massive than red or yellow stars.
* Faster Fusion: Their greater mass leads to much stronger gravity, causing them to burn through their hydrogen fuel at an incredibly fast rate.
* Shorter Lifespan: This rapid fusion means they have significantly shorter lifespans, often lasting only a few million years compared to the billions of years that smaller stars like our Sun live.
Think of it like this: A small, efficient car can travel for a long time on a full tank of gas. A powerful sports car burns through its fuel much faster, even though it can go much faster.
So, while blue stars are incredibly bright and powerful, their high energy output comes at the cost of a much shorter lifespan.
