It took me a year to return. I apologize for that. Everyone has family issues, right? I will try to post regularly.

My topic today is actually about dying stars, which die every day. It is unlikely that we will see a supernova in our lifetime, due to their long life span, some millions, even billions of years. However, here is a tidbit for you. If you didn't know already, we have, in our galaxy, one Red SuperGiant that may explode to a Supernova Type II. Or, it may already have exploded and we just don't know it yet.
From our Sun, it takes light about eight minutes to reach us, since its only 93 million miles away. But the Red SuperGiant is about 640 lightyears away. (That's roughly, 9,460,730,472,580,800 metres [exactly] times 640.)
This Red SuperGiant is called Betelgeuse and it lies in the Orion constellation. It is a possibility that Betelgeuse has already turned supernova and we're just waiting for it to reveal itself to us. It could show tomorrow, or in the next 1000 years.
But with every death of a star, births a new. In all sorts of nebulae stars are being born, nurtured by its surroundings, etc.-Meiko
