few new zealand stargazers may have received a
detailed view of the Andromeda spiral galaxies, M31
and M32, from temperate latitudes. They are too far
north to be easily seen from Wellington, (41 degrees
south.)

the infra-red picture gives a welcome rare insight
into the 'local group' of galaxies. (Spitzer space
telescope by NASA, dompost, 7-6-2006 pg. B2.) Thanks.

however, it does not answer several queries..

Why is Andromeda Galaxy not spiralling, zooming and
pulsing? Is it because of a fast shutter speed? (Yes,
1 minute) or the long-distance stitch?

Andromeda Messier-31 galaxy is approximately 2.5
million lightyears distant. the resulting picture [may
be] a composite of 50 images high by 60 images wide.

What is a square degree? Like the construction of an
innuit igloo iceblock-house. There are 41,253 square
degrees in a sphere , viz. 360 squared over pi.

Can I see Omega Centauri globular cluster overhead
with binoculars, mid 2006? Yes. WGTN NZ.
What is a galactic year?

Spitzer Space Telescope has captured a stunning
infrared view of Messier 31,
the famous spiral galaxy also known as
Andromeda.Andromeda is the
most-studied galaxy outside our own Milky Way, yet
Spitzer's sensitive
infrared eyes have detected captivating new features,
including bright,
aging stars and a spiral arc in the center of the
galaxy. The infrared
image also reveals an off-centered ring of star
formation and a hole in the
galaxy's spiral disk of arms. These asymmetrical
features may have been
caused by interactions with the several satellite
galaxies that
surround Andromeda."Occasionally small satellite
galaxies run straight through
bigger galaxies," said Dr. Karl Gordon of the Steward
Observatory,
University of Arizona, Tucson, lead investigator of
the new observation.
"It appears a little galaxy punched a hole through
Andromeda's disk, much
like a pebble breaks the surface of a pond."The new
false-color
Andromeda image is available at Andromeda Images
..Approximately 2.5 million
light-years away, Andromeda is the closest spiral
galaxy and is the only
one visible to the naked eye. Unlike our Milky Way
galaxy, which we
view from the inside, Andromeda is studied from the
outside. Astronomers
believe that Andromeda and the Milky Way will
eventually merge
together.Spitzer detects dust heated by stars in the
galaxy. Its multiband
imaging photometer's 24-micron detector recorded
approximately 11,000
separate infrared snapshots over 18 hours to create
the new comprehensive
mosaic. This instrument's resolution and sensitivity
is a vast
improvement over previous infrared technologies,
enabling scientists to trace the
spiral structures within Andromeda to an unprecedented
level of
detail."In contrast to the smooth appearance of
Andromeda at optical
wavelengths, the Spitzer image reveals a well-defined
nuclear bulge and a system
of spiral arms," said Dr. Susan Stolovy, a
co-investigator from the
Spitzer Science Center at the California Institute of
Technology,
Pasadena. The galaxy's central bulge glows in the
light emitted by warm dust
from old, giant stars. Just outside the bulge, a
system of inner spiral
arms can be seen, and outside this, a well-known
prominent ring of star
formation.NASA's Jet Propulsion Laboratory, Pasadena,

Very Interesting.....
What a spectacular sky we live under and in.
We are all a part......That is what makes it even better.
It would be interesting as to when we find God. Or are we viewing him and
or her.... as we speak....A playground of spheres, arcs, black holes, and
ever evolving "old history" and new......
Light years, and seconds.....It all depends on what scale we measure from.
Inches, feet, Miles, minutes, hours, days, years, meters, hecters,
kilometers, 10ths.....day/night......
Thanks for the view....
