When Sirius Goes SuperNova
Only 8.611 LY distant. I think we'll be cooked, literally.
The Sun isn't massive enough, BUT will run out of nuclear fuel in a few billion years, and swell to a red giant, and incinerate the Earth. On these happy notes ... |

On these happy notes ... Stars don't go supernova very often. Whenever they do we can usually see them even from as far away as distant galaxies. |

When Sirius Goes SuperNova
Suggest you google supernova and read. It's the likely end game of any
star with enough mass. On average, a supernova will occur about once every 50 years in a galaxy the size of the Milky Way. Put another way, a star explodes every second or so somewhere in the universe. |

So the probability of Sirius going supernova is almost non-existent. |

When Sirius Goes SuperNova
A star going supernova every 50 years in a galaxy of 200 billion stars is not very much. Well it's often enough to eat up all those stars in 4 billion years, which is less than 1/3 of the time since the alledged big bang. So the probability of Sirius going supernova is almost non-existent. A supernova is a transient astronomical event that occurs during the last stellar evolutionary stages of a star's life, either a massive star or a white dwarf, whose destruction is marked by one final, titanic explosion. Sirius qualifies ! |
