No one knows. But at 100 - 150 times the Sun’s mass, it doesn’t have much time left. And the presence of lots of nitrogen in the gas surrounding it is a bad sign: that means that the star was making heavy elements in its core, then belching them up into space. By the time a star like Eta Car is making nitrogen, it doesn’t have long left to go. And when it goes, it’ll <I>go</I>.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.badastronomy.com/bablog/2007/06/20/eta-car-tick-tock-tick-tock/"><P>So Eta Car is  ticking bomb.
