Fw: Star that is no longer there
Received;
Hi
Please find attached photograph I took of a couple of days
ago of a magnitude 5 star in the constellation of Cassiopeia.
But this is no ordinary star, in fact it is almost definitely no
longer there !
Below in green text is a quote from Armenian astronomer Garik Israelian who is part of a
team which has just published this unique and amazing discovery
"For the first time,
we see a star which most probably (99%) does not exist now, in our time.
The star HR8752 is few
thousand light years from us, so we are seeing it as it was a few thousand
years ago.
I have estimated that when
the stellar light corresponding to its present state reaches us, this star will
be seen to have exploded as Supernova. Our observations indicate spectacular
changes in the internal structure: the star is losing 1 solar mass every year !!! And its current mass is less than 20 solar masses.
It will not "expire" in 20 years, but in less than 1000 years it will
evolve so fast that the ONLY final solution for the star will be a Supernova
explosion.
http://www.iac.es/divulgacion.php?op1=16&id=774&lang=en
Attention! My statement
(that we are looking at a star which does not exist NOW) does not apply to any
other known stars in the Galaxy ・no matter how far away they are. More than 99% of the galactic
stars are stable enough that we can be sure that they are still there ・they exist NOW.
Of course you may say
"what about very distant galaxies, 10 billion light years away? The
universe is less than 14 billion years old, so maybe those far away galaxies do
not exist anymore?" Again, the answer is "They DO exist today".
The star HR8752 is dead. It
has become a black hole of a few solar masses - ie -
with a mass a few times that of our Sun."
I find it quite amazing to think that this normal looking star,
some 4.5 thousand light years distant and easily observed with a pair of
binoculars has already ended it's life.
One
day in the not to distant future people here on Earth may witness an incredible
sight in the sky as HR8752 is seen as a spectacular supernova in it's
final death throes before disappearing forever from our night skies...
Due
to the inclement weather here in the

Hi
Guys. Totally against the forecast for cloud and jetstream
we had a night of quite steady seeing but a bit misty requiring more gain and
less fps than normal. There was quite a bit of gain chasing required during the
capture runs to keep the histogram happy.
Once again I used a colour cam. I
daresay we all focus fiddle between rgb filters, but
that's not in the scheme of things with a colour cam.
I have put the colour channels out too for one pair
of runs, Is the C14;s corrector focusing them all
the same? looks ok to me, and certainly within range of the sharpening
tools, bearing in mind that the blue channel always suffers from seeing
more than the others,
WJ derotation was between 10 and
12 minutes per image
The GRS has some pink spots on its "hollow" side
edge

Mercury upcoming morning apparition...

Dear all
planetary observers -
As 2012 comes to close, I am seeking for Mercury observations for the upcoming
morning apparition.
Mercury passed inferior conjunction with the sun on November
17th. It just missed the transit of the sun by three days! Mercury will
appear in the morning sky a week later but by the end of the month, it
should be easily visible with the naked-eye about 45 minutes before
sunrise. The prime window to observe Mercury is during the first two weeks of
December with greatest elongation falls on December 4th. It will be at
least 20.5 degrees west of the sun and it will appear slightly more
than a half-disk (due to the elliptical orbit) at -0.4 magnitude.
There
are two things that make the apparition favorable. First: The angle of
the ecliptic is quite steep so Mercury appears higher in the sky.
Second: You can use Venus as guide to find Mercury even in daylight.
Mercury will stay within 10 degrees of Venus from November 28th to December
28th! One full month! But from December 4th to December 15th, Mercury will
be just under 7 degrees of Venus! This
is the greatest opportunity to observe Mercury at its best in
daylight. If you obtain both Mercury and Venus coordinations,
you can easily find Mercury when you use Venus as a starting point with RA
and Dec. Use low power! Also, you can focus on Venus and you are
sure to find Mercury with ease.
You
can use the JPL Horizons ephemeris at the day you are observing:
http://ssd.jpl.nasa.gov/horizons.cgi#top
Please,
send all observations to me at Frankj12@aol.com.
Thank You,
Frank J MELILLO (NY, the
ALPO Mercury Coordinator

NEREIDUM
MONTES HELPS UNLOCK MARS’ GLACIAL PAST
On 6 June,
the high-resolution stereo camera on ESA’s Mars
Express revisited the Argyre basin as featured in our
October release, but this time aiming at Nereidum
Montes, some 380 km northeast of Hooke crater.
The
stunning rugged terrain of Nereidum Montes marks the
far northern extent of Argyre, one of the largest
impact basins on Mars.
Nereidum Montes
stretches almost 1150 km and was named by the noted Greek astronomer Eugène Michel Antoniadi
(1870-1944).
Based on
his extensive observations of Mars, Antoniadi
famously concluded that the ‘canals’ on Mars reported by Percival Lowell were,
in fact, just an optical illusion.
The images
captured by Mars Express show a portion of the region, displaying multiple
fluvial, glacial and wind-driven features.
Extensive dendritic drainage patterns, seen towards the north (lower
right side) of the first and topographic images, were formed when liquid water
drained into deeper regions within the area.
On Earth,
tree-like channels of this kind are usually formed by surface runoff after
significant rainfall, or when snow or ice melts. Similar processes are thought
to have occurred on Mars in the distant past, when scientists now know there to
have been water on the surface of the Red Planet.
Several of
the craters within the region, particularly in eastern parts (lower section) of
the first image, show concentric crater fill, a distinctive Martian process
marked by rings of surface fluctuations within a crater rim.
The ratios
between the diameter and depth of the filled craters suggest that there may
still be water ice, possibly in the form of ancient glaciers, present below the
dry surface debris cover.
Scientists
have estimated that the water-ice depth in these craters varies from several
tens up to hundreds of meters.
The largest
crater on the south western side (top-left half) of the first and topographic
images appears to have spilled out a glacier-like formation towards lower-lying
parts of the region (shown as blue in the topographic image).
A smooth
area to the east of (below) the glacial feature appears to be the youngest
within the image, evidenced by an almost complete lack of cratering.
Another
indication of subsurface water is seen in the fluidized ejecta
blanket surrounding the crater at the northern edge (right-hand side) of the
first and topographic images.
These ejecta structures can develop when a comet or asteroid hits
a surface saturated with water or water ice.
Finally,
throughout the images and often near the wind-sheltered sides of mounds and
canyons, extensive rippling sand dune fields are seen to have formed.
In-depth
studies of regions such as Nereidum Montes play an
essential role in unlocking the geological past of our terrestrial neighbor, as
well as helping to find exciting regions for future robotic and human explorers
to visit.
