    Wow. I wonder, if it exploded tomorrow, how long the light show would last?

    It's 7500 light years away. It probably already exploded years ago.

    Yeah, they should have entitled the article, "Come light from Eta Carinae's explosion, get to us already!"

    Or, "Eta Carinae, please make your explosion observable from our frame of reference."

    Ok, so I'm not so good with the space and light stuff. But if ts 7500 light years away doesn't that mean it could have already exploded and we don't know it?

    Yup, and to blow your mind further, there may be many more stars out there that have done the same thing, and we don't know it.

    Do you see that double-lobed structure in the article picture? From what I understand, we should be very very happy that we can see it. If it looked like just a globe surrounding Eta Car, that would probably mean its poles were directly aligned with us. That would further imply we were looking down the barrel of a nearby long gamma-ray burst - which could fry our world like an apple under a rocket engine.

    Fortunately, it's pointed away from us. The Earth escapes certain doom again!

    Thats very cool, but the fact that we might never see it during our lifespan is both disspointing and depressing.

    Pretty wild article. It'd be neat to see something like that show up on our 'scopes in the course of our lifetimes.

    Incredibly, a Google search for "physics is phucked" returns only three results.

    That means it would take 7500 years for the light from that explosion to reach Earth.

    Light year = time of light in a year.

    ie. Something traveling at the speed of light takes 1 year to get from point A, to point B. Therefor, point A and B are 1 light year apart.

    Well, it would certainly be something interesting to look at...for the first couple years. Once it goes off, how long will it be visible?
