Astronomers studying 17 supernova remnants... a surprising discovery

Astronomers studying 17 supernova remnants, both in and near the Milky
Way, have made a surprising discovery. By analyzing the shape of the
remnants--created when massive stars exploded--they could tell what type
of supernova caused the debris cloud. As they reported recently in The
Astrophysical Journal Letters, a supernova known as a type Ia--caused
when a sunlike star in a binary system draws in too much gas from its
partner--generates a remnant cloud that's nearly spherical. But when
stars that are much more massive explode, their remnant clouds are
asymmetrical, as in this image of G292.0+1.8, located about 20,000
light-years away in the constellation Centaurus. (Photo:

There are other shapes that are both symmetrical and not spherical,
such as the hourglass or butterfly shapes. Was there any correlation
to these?

These objects are not supernova remnant, but planetary nebulae.
There is no 'explosion' in such a case, only an ejection of peripheral
layers of a star.

I have one copyright to my name at least one I chose to apply , a work
from 1990 based on stellar efficiency which involves two large
external rings and a smaller intersecting ring with one temporary
conclusion to consider.Although now a private work now,the idea is
still applicable - the higher elements forged within stars and which
are abundant here on Earth arise from considering the evolutionary
stage of stars known as a supernova as an intermediary stage rather
than the demise of a star.in other words,the elements in our bodies
and our planet arose from our own Sun at a different evolutionary
stage.
It was a joy to see the pictures of SN1987A in an era which is wrapped
up in geometric impossibilities such as 'black holes' and 'big
bang;,unlike everyone else here I have the luxury of working on
stellar geometry before the images of that geometry actually emerged

None of you appear to like astronomy or putting things in context,not
even discussing possibilities but it was not always like that.Although
a private work,the reasoning behind the large and small rings is
something in context of natural efficiencies that I see all around me
and this is something that would normally appeal to dynamicists who
unfortunately are stuck or are comfortable with a tainted Ra/Dec
outlook for the universe.
Maybe the thing about this is that there are no genuine or courageous
dynamicists anyway along with no astronomers
palsing

Not quite right; the elements in our bodies and our planet AND our sun
were all present in the molecular cloud from which they all condensed.
Any heavy elements synthesized within the sun, either there now or to
be synthesized later, will stay right where they are for a very long
time... there is no mechanism to get them outside of the sun while it
is still in a stable period.

Pray tell, just how are you defining "stellar geometry"?
> Although a private work...
I think it best to keep you private works private...
