NASA just announced the detection of massive Gamma and X-ray bursts from several candidate supernovae.

The recent bursts "may be the first time we see an X-ray flash lead to a supernova," said theorist Stanford Woosley of the University of California at Santa Cruz.

This would make the fist time we've anticipated and witnessed such activity instead of afterglow.

    But will the supernova actually appear (to us on Earth) in a week, or in another thousand years? Like, what's the time between the initial flash and the nova itself?

    the only way we'd be able to witness an actual supernova from the original source within our lifetimes would mean the destruction of all life in the solar system.

    Kickaha and Amorph couldn't moderate themselves out of a paper bag. Abdicate responsibility and succumb to idiocy. Two years of letting a member make personal attacks against others, then stepping aside when someone won't put up with it. Not only that but go ahead and shut down my posting priviledges but not the one making the attacks. Not even the common decency to abide by their warning (afer three days of absorbing personal attacks with no mods in sight), just shut my posting down and then say it might happen later if a certian line is crossed. Bullshit flag is flying, I won't abide by lying and coddling of liars who go off-site, create accounts differing in a single letter from my handle with the express purpose to decieve and then claim here that I did it. Everyone be warned, kim kap sol is a lying, deceitful poster.



    Now I guess they should have banned me rather than just shut off posting priviledges, because kickaha and Amorph definitely aren't going to like being called to task when they thought they had it all ignored *cough* *cough* I mean under control. Just a couple o' tools.



    Don't worry, as soon as my work resetting my posts is done I'll disappear forever.

    Silly people . . . the flash we detected is probably thousands of years old . . . the super novas will be thousands of lights years away, but maybe they're going super nova happened shortly after the gamma ray flashes. IOW, we may see them blow quite soon.



    I hope that they get good visual translations of these events . . .



    Space is awesome!!!



    & I mean that literally

    It'll take me a bit to find the perfect linkage, but until that edit...



    How are SN discovered?



    NASA Goddard High Energy Astrophysics Lab's excellent Intro to SN pages



    Some of these pages talk about the Gamma Ray Bursts, some link to Chandra, some to pulsar study



    video from Hubble of SN Remnants influenced by Pulsar/solar wind



    The team made news for early photos (by chance then, not by GRB/X-ray clues first) back in '02



    Modern SN watching has been active scientifically for about 100 years, but there are historical records of Kepler's star going Nova in 1604, and numerous references to suggest SN recordings in Egypt and China thousands of years ago.



    The problem has been that nobody knew where or when to look, so you either got lucky (usually with poor instruments) or got to the event late (big scopes take time to skew once reports tell them where). Turns out a lot of the research interest requires knowledge of the earliest spectra in the burst.



    Knowing where and when to focus a network of large scopes might allow interferometry and spectroscopy of unprecedented accuracy. Tying precise measurement of the GRB/X-Ray spike to its associated SN might allow new models of stellar evolution, and could help refine our maps of galactic development.

    that was my point. i wasnt clear, sorry.

    You know, that would really suck ... but still be kinda cool at the same time.

    Which will probably never happen. Our sun is a medium star. Which in most cases they just turn into white dwarfs then black dwarfs. Large stars turn into supernova's and into a neutron star or black hole.

    The light will arrive years later in its time . . . but it is the only thing that could possibly 'get here' between the time of the SN and our present . . . . nothing travels faster than light.

    So, when it arrives it will look like we are seeing a star just as it blows up.



    That's as close to simultaneity as you get when considering such vast distances.



    . . . or am I restating the obvious?!
