It is not a prediction of a supernova. The thread title should read "Exploding star can be seen from earth for 2 weeks".
The supernova occurred in a galaxy 21 million light years away. It took 21 million years for the the light from it to arrive at Earth a couple of days ago. The light will continue to arrive for a while. But, as the article points out, it's not really going to be noticeable.
edit on 8/27/2011 by Phage because: (no reason given)
The distance is absolutely mind boggling 21 million light years away. Well the distance that light travels in one year is 10 Trillion 10,000000000000 Kilometres en.wikipedia.org... so that has to be multiplied by 21,000,000 resulting in a huge number of Kilometres that I have no idea how to represent here.

How do they know it's going to explode so far ahead of time?
I mean, is the star swelling or collapsing or something? How can they be so sure that the indicators are that precise, that they can predict a super nova 2 weeks ahead of time?
I'm sure the answer is amazing.
Mate, read the article please.
It allready happenned, it just takes some time for us to see it..........
These images show Type Ia supernova PTF 11kly, the youngest ever detected -- over the past three nights. The left image taken on Aug. 22 shows the event before it exploded supernova, approximately one million times fainter than the human eye can detect. The center image taken on August 23 shows the supernova at about 10,000 times fainter than the human eye can detect. The right image taken on Aug. 24 shows that the event is six times brighter than the previous day. In two weeks time it should be visible with a good pair of binoculars.
