Submission + - Scientists await the explosion of Eta Carinae (harvard.edu) 1
Urbanator writes: According to the Chandra X-Ray observatory, Eta Carinae, a star about 7,500 light years away and 100 to 150 times the mass of the sun is set to explode. If this occurs the star may be light enough to rival a full moon for a short period of time. New composite images of the star are shown, displaying the results of an earlier explosion from the 1840's which caused material about 10 times the mass of the sun to eject from the star and form a nebula around it. Of course for all we know, this explosion may have already happened sometime in the last 7,500 years.
