How Long Has It Been Since We Saw A Supernova?

Betelgeuse has gotten dramatically dimmer over the last few weeks, astronomers say the change probably isn’t a symptom of an impending stellar explosion.

That’s good news for any planets in the star’s orbit... But it’s disappointing news for Earth-based astronomers and stargazers, who haven’t been able to watch the death of a star with their unaided eyes since 1987, and may not have another chance for centuries.

In 1987, a supernova called SN 1987A, marked the death of a blue giant star in the Large Magellanic Cloud, one of the dwarf galaxies that orbits the Milky Way. 168,000 years after the star ran out of fuel and collapsed in on itself, the light of the resulting explosion reached Earth’s southern hemisphere – preceded a few hours earlier by a series of neutrino bursts.

The car AND the blonde became too expensive to keep so I got rid of them both. ;)

Not sure when the last super-nova was but I predict the next will be early next Nov 4th

If nothing can go faster than light, then how did those neutrinos get here before the light did?

One would assume that the neutrino burst happend before...

“It’s as they say, you just passed them on to another good home.”

I was VERY careful about where the car went.
The blonde...not so much.

“Blonde? There was a blonde too?”

Yup.
Divorcing the blonde is what really made it too expensive to keep the car.
The car I had still looks great.
The blonde has been rode hard and put away wet too many times to count and shows it. =:0)
