There have been supernova, visible to the unaided eye, documented throughout history. However, this is the first modern supernova that we're able to witness with advanced instruments, and it should teach us a lot about how stars form and die. Hence it doesn't matter when it actually exploded. You're just pointing out the obvious, as many diggers do, unnecessarily. - greymaxcat, on 10/12/2007, -0/+15I thought this was a story about Starr Jones eating too much at Denny's....
- monsters, on 10/12/2007, -1/+12what? of course, and in fact we can likely tell exactly how long ago....
- frogpelt, on 10/12/2007, -0/+9Everything we know about happened in the past! Congratulations on your discovery!
- inactive, on 10/12/2007, -0/+8I'm willing to go crazy and bet a whole lot of money that it did, in fact, explode years ago.

Woohoo.... I'll go mark it down on my calendar. - ahawks, on 10/12/2007, -0/+4I was going to edit my comment to put this info in, but time ran out.
According to Wikipedia, this star is 1,950 lightyears away. So really, 2,000 years is a pretty small time difference when dealing with such things, I don't suppose timeframe really matters. - argonaut99, on 10/12/2007, -0/+3For the record, this will most likely be nothing like our sun's situation in a few billion years. Sure, it's likely to go through the red giant and white dwarf stages, but that should be it (i.e. no companion star to provide the critical mass needed for supernovae).
Photos and more info on this star:
http://www.ras-observatory.org/ras/Research/ICRAR/Observers/Ernesto_Guido/RS_Ophiuchi/rs_ophiuchi.html - DBCubix, on 10/12/2007, -0/+3Its just a wafer-thin mint...
- frizop, on 10/12/2007, -0/+3It's not really a question so much as it _should_ be a statement. This happen many, many years ago. However, were are now able to see it.
- denjin, on 10/12/2007, -0/+2This is an interesting story, but the blurb for the title here is inaccurate. They obviously haven't glimpsed an "exploded star". It will explode some day in the next however many thousand years.
If you're alive, might want to hide a bit then, though. ;) Supposedly a Type 1A Super Nova is a problem if you're less than 3,000 light years from it (this star is under 2000 I think?). - nodrew, on 10/12/2007, -1/+3"old news that star probly went suprnova a million years ago how is this new newd?"
You sir are an idiot.
The star in question is 1,950 light years away and thus could never have super nova'd more than 1,950 years ago. However, in these circumstances, it is considered that time is relative, not absolute. Therefore, while it may have actually occurred thousands of years ago, we cannot fully judge the time until we are able to witness it.
In any case, learn to spell, learn to type and most of all, learn to fraken read. - Presentlight, on 10/12/2007, -0/+2Not to be critical, but that is a terrible headline to have posted. It is stated by the poster both that the scientists glimpse a star that has "exploded" while at the same time stating that the star is on the "brink of exploding." Something cannot both be on the brink of exploding and have already exploded.
- apocalizer, on 10/12/2007, -0/+2That was a lame excuse to make a comment about Star Trek. (Either that or the US Navy has more capable aircraft carriers than I thought.) Besides, if that ship was able to get away, where would the suspense be?
- jmacdonagh, on 10/12/2007, -0/+2" 'It could be tomorrow, but most likely it'll be 1,000, 10,000, 100,000 years from now,' says Jeno Sokoloski."
God dammit! - hodyoaten, on 10/12/2007, -0/+2OK, wait:
(1) These things are so bright they temporarily outshine the entire galaxy they're within.
(2) The star is 1950 light years away... or about 2% the width of our galaxy.
(3) The 1604 supernova was 10 times further away than this star.
The article just completely glossed over how close this supernova will be. At least if I wake up at 4 am and it's daylight outside, I'll know what it is. - crawf061, on 10/12/2007, -2/+3that artist's impression is very nice... he's got a good imagination!
- fatb0b, on 10/12/2007, -0/+1and it's a DUPE
http://digg.com/space/Scientists_Spot_Star_Set_to_Supernova_Soon - MarkCiccone, on 10/12/2007, -2/+3Foreshadows our situation in a couple billions years :D
- mfratt, on 10/12/2007, -1/+2Ever notice how, whenever the Enterprise is near a star about to explode, it manages to get stuck there for some random reason (crew stuck on an abandoned ship, drunk engineers pulling out isolinear chips, etc) until last possible second?
- rblinne, on 10/12/2007, -0/+1Some background on RS Oph from AAVSO:
http://www.aavso.org/vstar/vsots/0500.shtml - trib4lmaniac, on 10/12/2007, -2/+1Well, when that thing explodes, I'm going to have a hard time getting to sleep at night with all that starshine around!
- ahawks, on 10/12/2007, -3/+1I do wish they'd mentioned which timeframe they're talking about. How many lightyears away is it? If it's far away, it may have already blown and it could still be 10,000 years before we know.
I assume they are talking about from our perspective, because we have no way of knowing what has happened to it in the time it took for its light to reach us. - Ndiggnation, on 10/12/2007, -9/+2Some might not like what he said (for reasons unknown), but he is right.
- bobothn, on 10/12/2007, -10/+2old news that star probly went suprnova a million years ago how is this new newd?
- fatb0b, on 10/12/2007, -10/+2Dupe, same exact story.
http://digg.com/space/Scientists_Spot_Star_Set_to_Supernova_Soon - stylerm, on 10/12/2007, -26/+5Because of how long it takes light to travel, for all we know the star could have exploded years ago.
