It is getting close to your mother's and
your father-in-law's birthdays, this is what is on your mind. You are also
thinking of the photo Doug sent you yesterday.

Sculptor Galaxy
PHOTO: ALMA Telescope Captures NGC 253's Vigorous Gas Emissions
Sometimes science can be beautiful. Just take a look at
this image released by the huge new ALMA telescope in Chile. It reveals
enormous gobs of cold, dense gas blasting out from the Sculptor Galaxy that may
hold clues as to why astronomers have had trouble finding high-mass galaxies
that theories predict should exist, according to a new study.
The different colors represent
different emission intensities, or amounts of gas released -- purple
corresponds to the brightest, most intense gas emissions and red is the least
intense.
The Sculptor Galaxy, also called
the Silver Dollar Galaxy and more formally known as NGC 253, is a spiral-shaped
galaxy located 11.5 million light-years away from our solar system. It has been
classified as a starburst galaxy because it forms stars at a very high rate. It
was discovered in 1783 by Caroline Herschel, an astronomer whose brother and
collaborator, Sir William Herschel, discovered infrared radiation.
And now the ALMA (Atacama Large
Millimeter/sub-millimeter Array) telescope, newly inaugurated in March 2013,
has revealed new secrets by detecting radio wave emissions from the galaxy,
which have been converted into the three-dimensional visualization above.
“With ALMA’s superb resolution and
sensitivity, we can clearly see for the first time massive concentrations of
cold gas being jettisoned by expanding shells of intense pressure created by
young stars,” study co-author Alberto Bolatto, astronomy professor at the
University of Maryland, said in a written statement.
The galaxy expels gas when the
newborn stars kick out radiation and strong winds. The researchers found that
the galaxy expels almost 10 times the sun's mass in gas every year. Meanwhile,
the galaxy might run out of gas in 60 million years. This could starve future generations
of stars, preventing them from having the fuel they need to form, and ending
the galaxy's starburst.
This finding could help explain why
computer models have predicted that older galaxies should have higher masses
and more stars, but astronomers have not been able to observe them.
The research was presented in a paper and published in
the July 25, 2013 issue of Nature.

And, an added thank you to my old friend who connected me with this article, John Douglas Goss, for being who he is. - rho

1002 hours. What this photo made me think of immediately is how unique
and beautiful nature is and sometimes even more so as if seen by alien eyes.
Shortly thereafter "as if seen by a soul". In an earlier post I conceived
a concept of a soul searching for a heartanmind to nibble on and this
photograph of a very large gaseous object to something so seemingly small
because it has no mass. Anyway, as a visual it works for me.
You are concerned with "I conceived a
concept of a soul search," because other people might just as well have
conceived it and the point is not to copyright the concept and who knows what
else rolls into your mind. What do you have to say about this, orndorff? -

1010 hours. Your paragraph makes this even more awkward. Arrogance, on
my part, and false modesty another splash against the central thought. I love
the photo and presently it is my desktop photograph. I can imagine a soul
searching for a particular 'flavor' of color to nibble on and not realizing
what it is sheorhe is eating; how sheorhe will be changed/evolved by having
eaten a human-like heartanmind. Looking for one thing and finding another
is very much a part of our nature and I would like to see this as a part GMG,
because 'there is an observed human truth to the process'. I see a humor in it
. . . souls don't know any more than we do, maybe not as much, immortal or not.
And, the further humor is that humans don't really know much of anything for
sure. This is so very amusing to me. LOL.
It appears your '"central thought' is
now in calmer waters. - Amorella
1021 hours. It is. The arrogance and false modesty is just so much
rubbish when compared to a well working inner humor.
Mid-afternoon.
You have stopped at Kroger's on Tylersville and Cox after a late lunch at
Smashburgers. The rains and the lower dark clouds have let up; cumulus and blue
sky are prevailing from the west. You have a few more errands this afternoon. Let's
work on Grandma 20 while we can. - Amorella
1628 hours. We sit here in Deerfield Township's Rose Hill Cemetery;
Carol on page 121 of The Columbus Affair, and me writing. I have 897 sensible
words on Grandma 20 and am need of deleting a hundred.
Make
a copy of what you have presently and work from the copy as time and
inclination permit. - Amorella
1950 hours. We mowed the lawn (humidity was up), watched the national
news, both ABC and CBS and Carol wants to watch a show at eight. We topped off
our left over Papa John's pizza and once I check my email I'm ready to tackle
Grandma 20 and hopefully finish it up this evening.
Post and relax, boy. If you don't complete
it tonight you can tomorrow. - Amorella
Ah, yes, if I live through the night.
