Red giant stars are many, and yet still a little hard to come by, as

UV and IR)

*Mira A of several hundred solar radii (UV colorized as bluish): “A

Sirius B could have been much like an image of Mira A, except a whole
lot larger (1000 solar radii), as viewed in visible and near IR

There are many possibilities, as for how Sirius B used to function as
a truly massive (9 solarmass)star, thereby extremely hot and fast
burning prior to becoming a red supergiant, creating an impressive
planetary nebula phase before ending as the little white dwarf. *For
all we know Sirius B was even a variable kind of red giant and then
perhaps a slow nova flashover phase prior to finishing off as the
white dwarf.
These following examples are probably similar or perhaps representing
a slightly smaller version of what the Siriusstar/solar system looked
like once Sirius B had started turning itself from an impressive red
supergiant into a white dwarf of perhaps 1/8th its originalmass,
taking roughly 64~96,000 years for this explosivemassshedding phase
to happen. *A few tens of billions of years later is when such a white
dwarf eventually becomes a black dwarf, kind of black diamond spentstar, in that our universe may or may not be quite old enough to
display such examples.

Betelgeuse has been a massive red giant at 20+ fold themassof our
sun, and likely worth nearly 3 fold themassof the original Sirius B,
and currently expanded to 1000 solar radii, and it'll be truly
impressive nova whenever it transforms into a white dwarf nearly the
size of Jupiter.
The soon to be renewed and improved Hubble should accomplish the
improved spectrum and resolution of most everything, along with other
existing and soon to be deployed telescopes should give us even better
composite examples of what Sirius B used to look like. *This may give
some of us a better interpretation as to what transpired right next
door to us, as well as having unavoidably contributed to some of what
our solar system has to offer.
We seem to have become closely associated with the Sirius star
cluster, even though Sirius has been a relatively newish and extremely
vibrant stellar evolution (quite possibly contributed from another
galaxy), and especially terrestrial illuminating of the first 200~250
million years worth.
It took a cosmic molecular cloud worth perhaps at least 120,000 solar
masses in order to produce such a 12+ mass star system, leaving 99.99%
of that molecular mass blown away and to fend for itself, at a place
and time when our existing solar system wasn't any too far away.
Others might go so far as to suggest a molecular cloud mass of 1.2
million, and others yet would prefer that this terrific cloud had
emerged from a smaller galaxy that encountered our Milky Way.
There's no way that our passive little solar system wasn't somehow
directly affected by and otherwise having become somewhat tidal radius
interrelated with such a nearby mass, at least associated with the
mutual barycenter that's primarily dominated by the Sirius star/solar
system.
Lo and behold, it seems the mergers of galactic proportions isn’t
nearly as uncommon as some naysayers might care to think.

According to several physics and astronomy kinds of observationology
science (deductive interpretation of eye-candy), our Milky Way is made
up of at least two galactic units, with more on their blue-shifted way
towards encountering us. Seems hardly fair considering that
everything was supposedly created via one singular big bang, not to
mention that hundreds to thousands of galaxies seem headed into the
Great Attractor (including us) for their final demise and/or rebirth.

Don’t forget to appreciate those Hubble, KECK and multiple other
archives (including those of FAS) depicting “colliding galaxies”, soon
to be ESA enhanced and expanded upon via a trio of their impressive
orbital observatories, not to mention whatever the renewed and
improved Hubble plus our next generation of orbital observatories
should further document. It may even become hard to find galaxies as
massive as ours and Andromeda that are entirely original without their
having gown via mergers.
Where's the all-knowing expertise from FAS, telling us whatever they
seem to know best or at least suspect is most likely. Surely these
brown-nosed clowns, faith-based bigots and closed mindsets of our
Usenet/newsgroup that are enforcing their mainstream status quo (much
like my personal Jewish shadow tries to do), are hopefully not
speaking on behalf of FAS.
