I can see clearly now, but then so can ETs half as smart see even
better
If the extremely nearby planet Venus that gives us panspermia flu most
every 19 months is officially mainstream taboo/nondisclosure rated
(much the same taboo/banishment as for our moon or its L1), then
perhaps going further out is the only viable option for this paranoid
Usenet/newsgroup that so fears anything new or much less revision of
any kind.
HR 8799 at 130 ly distance, as viewed by a pair of terrestrial
telescopes having to deal with atmospheric distortions, offers us a
good example of what ETs might view of our solar system. However,
imagine if such telescopes were in orbit, whereas instead of just
obtaining those deep IR detections of worthy exoplanets, whereas those
better equipped ETs could go for a visual and even the far better UV
look-see at us.
Too bad we still can not manage to place a pair of super-sized
telescopes in LEO, or much less within the Earth-moon L1 (Selene L1
and perhaps Selene L2) whereas the bulk of whatever volume or mass
would make hardly any difference. Even a dirt cheap TRACE(e2) which
could give us a 100x better than existing TRACE resolution plus
superior dynamic range of our own sun would have been a nice thing as
of a decade ago. Deploying a TRACE(e3) with sufficient DR(dynamic
range) for looking directly at the Sirius star/solar system should by
now have been possible, and we might even discover Sirius C as well as
the original molecular cloud which gave such a recent and aggressive
birth to Sirius, and can't be any too far off considering how recently
everything evolved.
The vast majority of exoplanet worlds may be inhospitable to naked
humans for any number of reasons, but just imagine what happened
within our environment of this most recent cosmic era, while the
impressive Sirius solar system was getting created from such a massive
molecular cloud of perhaps 120,000 solar masses (or was it another
galactic black hole merging kind of thing), as for Sirius B having so
vibrantly evolved itself so quickly into becoming the red supergiant
and then suddenly becoming the little white dwarf, is what must have
been every bit as good as our having a second sun, especially
interesting if we’re still making our trinary orbit every 100 thousand
years. But then it seems we can’t discuss intelligent other life, no
matters how probable or technology assisted, without every topic
attracting those brown-nosed clowns like a swarm of killer bees.

“Red Giant Star Found to Have Massive Tail”

*Mira A of several hundred solar radii (UV colorized as bluish): “A
dying star situated 400 light years away from us exhibits an unusual
and massive tail of heated gas that spreads for more than 13 light
years.”

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 solar mass) 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 Sirius star/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 original mass,
taking roughly 64~96,000 years for this explosive mass shedding 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 spent
star, 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 the mass of our
sun, and likely worth nearly 3 fold the mass of 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.
The absolutely vibrant and cosmic stunning Sirius Star/solar system
birth as of 250~300 MBP started off at ~12 Msun, burned through the
vast bulk of its hydrogen extremely fast and only somewhat recently
became worth ~3.5 Msun, as having lost 8.5 of its solar masses, as
such the original mass is still existing elsewhere and most likely
producing photons of its own or as part of some other star/solar
system.
According to the vast majority of the best available experts, the mass
of our universe stays exactly the same, no matters what takes place,
but as a whole we seem to keep getting more and more of them photons
(mostly of those we can’t see) and possibly even more of those free/
rogue electrons and positrons to deal with. *However, is there any
limit in physics or quantum whatever as to how many photons this
universe or any given cubic light year can safely contain?
In addition to whatever a dense molecular cloud of hydrogen and helium
represents as an average population of 1e6/cm3 (1e12/m3) for the
natural cosmic evolution process of creating stars and essentially
everything else, how about we start off fairly small in order to
figure out what the maximum number of photons that a given IGM cubic
second (2.7e25 m3) can possibly contain, outside of whatever molecular
clouds or stars represent. *Even though the average cubic second of
the IGM might offer as little as 2.7e30 raw elements of mostly
hydrogen and helium atoms, there’s always the minimum 3D worth of
1024^6/cm3 * 1e6 = 1.153e24 photons/m3 as coexisting within each cubic
meter of IGM, thereby we have a minimum of 3.113e49 photons per cubic
second. *The photons per universe having the volume of 1.7e80 m3 =
6.296e54 ly3 is thereby 6.296e54 * 3.113e49 = 1.96e104 photons/sec,
times the age of our universe and counting.
Notice how certain faith-based mindsets (mostly of the Old Testament
thumping and politically skewed types of the born-again republican and/
or pretend-Atheist kind) are continually obfuscating by acting
oblivious and/or dumbfounded as to most of everything around us,
especially if such involves anything of ETs or bad and otherwise
unexpectedly spendy as hell. *Of course their not willing to share the
truth about much of anything doesn’t exactly help.
Secondly, notice how those in charge of most everything can’t ever
manage to say with any expertise or much less supercomputer simulated
within their own peer replicated results, as to where exactly the very
recent creation/birth of the truly massive Sirius star/solar system
took place, other than insisting it was supposedly nowhere nearby our
solar system. *However, I find these highly subjective and typically
obfuscation loaded kinds of replies somewhat disingenuous and/or less
believable than LeapFrog published infomercial physics along with all
of their nifty eye-candy science stuff, but then that’s understandably
setting our ‘no child left behind’ of uneducated truth standards a bit
high.
