Eta carinae
from the shape and direction of both lobes, it appears this thing is going Kaboom in other direction You all burning my brain up, need another ice cold one

Hello All
Eta Carinae
Has already a Neutron Core
It is so massive that it will go through many stages of ejecting its atmosphere and leaving behind it the core to regenerate new shells. I maybe wrong here. But! why should the star completely explode and go through the process of collapsing.
In this case we do have the evidence that 150 years ago it did eject its shell.

The above links mostly talk about collapsing gas.

Your right Dave it does seem that Eta Carinae is part of a binary system.

Super picture... Description makes me wonder how such a structure could be formed. How about this idea?
If a relatively large object were orbiting Eta Carinae, the object would prevent the star's expulsion of gas and dust from being spherical. Instead, the object would 'deflect' the gas and dust expelled toward it -- creating this 'wasp waist' effect. Such a scenario would also account for the 'wisps' noted in the description. Some of the gas and dust not repelled/deflected by the large object would converge on the side opposite the star -- like an eddy downstream of a bridge pier.
Any thoughts??
