“Red supergiants are some of the most massive and brightest stars, but they don’t live that long. In human terms, Betelgeuse is a geriatric at 10 million years old. It is nearing the end of its life. By contrast, our smaller sun is roughly 4.5 billion years old, just middle-aged.
“Red supergiant stars like Betelgeuse die in a spectacular fashion: after exhausting all their hydrogen and helium they collapse onto themselves, and finally explode in a supernova, one of the most cataclysmic events in the universe. And Betelgeuse is near the end of its life. “
As you can observe, if Betelgeuse were centred where the sun is, the radius of Betelgeuse would extend beyond Mars. Life would not have had time to evolve with so short a stellar life span.
We shall miss the shoulder of Orion when it blows up. Orion has been a marker of the autumn and winter sky since the dawn of man.
