Any Interesting Astronomy Evemts in WV, NC or SC?

I’m headed for the three states mentioned in Subject. I’ll be touring those
states from June 4 to June 13. Museums, fair, amateur club meetings,
lectures, public or government observatories?

Spitzer: Clarification on the Milky Way Structure

Two of the Milky Way’s Spiral Arms Go Missing

St. Louis, Mo. — For decades, astronomers have been blind to what our galaxy,
the Milky Way, really looks like. After all, we sit in the midst of it and can’t
step outside for a bird’s eye view.

Now, new images from NASA’s Spitzer Space Telescope are shedding light on the
true structure of the Milky Way, revealing that it has just two major arms of
stars instead of the four it was previously thought to possess.

"Spitzer has provided us with a starting point for rethinking the structure of
the Milky Way," said Robert Benjamin of the University of Wisconsin, Whitewater,
who presented the new results at a press conference today at the 212th meeting
of the American Astronomical Society in St. Louis, Mo. "We will keep revising
our picture in the same way that early explorers sailing around the globe had to
keep revising their maps."

An artist’s concept of the structure of our two-armed Milky Way is online at
http://www.nasa.gov/mission_pages/spitzer/multimedia/20080603a.html .

Since the 1950s, astronomers have produced maps of the Milky Way. The early
models were based on radio observations of gas in the galaxy, and suggested a
spiral structure with four major star-forming arms, called Norma,
Scutum-Centaurus, Sagittarius and Perseus. In addition to arms, there are bands
of gas and dust in the central part of the galaxy. Our sun lies near a small,
partial arm called the Orion Arm, or Orion Spur, located between the Sagittarius
and Perseus arms.

"For years, people created maps of the whole galaxy based on studying just one
section of it, or using only one method," said Benjamin. "Unfortunately, when
the models from various groups were compared, they didn’t always agree. It’s a
bit like studying an elephant blind-folded."

Large infrared sky surveys in the 1990s led to some major revisions of these
models, including the discovery of a large bar of stars in the middle of the
Milky Way. Infrared light can penetrate through dust, so telescopes designed to
pick up infrared light get better views of our dusty and crowded galactic
center. In 2005, Benjamin and his colleagues used Spitzer’s infrared detectors
to obtain detailed information about our galaxy’s bar, and found that it extends
farther out from the center of the galaxy than previously thought.

The team of scientists now has new infrared imagery from Spitzer of an expansive
swath of the Milky Way, stretching 130 degrees across the sky and one degree
above and below the galaxy’s mid-plane. This extensive mosaic combines 800,000
snapshots and includes over 110 million stars.

Benjamin developed software that counts the stars, measuring stellar densities.
When he and his teammates counted stars in the direction of the Scutum-Centaurus
Arm, they noticed an increase in their numbers, as would be expected for a
spiral arm. But, when they looked in the direction where they expected to see
the Sagittarius and Norma arms, there was no jump in the number of stars. The
fourth arm, Perseus, wraps around the outer portion of our galaxy and cannot be
seen in the new Spitzer images.

The findings make the case that the Milky Way has two major spiral arms, a
common structure for galaxies with bars. These major arms, the Scutum-Centaurus
and Perseus arms, have the greatest densities of both young, bright stars, and
older, so-called red-giant stars. The two minor arms, Sagittarius and Norma, are
filled with gas and pockets of young stars. Benjamin said the two major arms
seem to connect up nicely with the near and far ends of the galaxy’s central bar.

"Now, we can fit the arms together with the bar, like pieces of a puzzle," said
Benjamin, "and, we can map the structure, position and width of these arms for
the first time." Previous infrared observations found hints of a two-armed Milky
Way, but those results were unclear because the position and width of the arms
were unknown.

Though galaxy arms appear to be intact features, stars are actually constantly
moving in and out of them as they orbit the center of the Milky Way, like London
commuters in a busy traffic circle. Our own sun might have once resided in a
different arm. Since it was formed more than 4 billion years ago, it has
traveled around the galaxy 16 times.

Co-investigators of this research include Ed Churchwell, Marilyn Meade and Brian
Babler of the University of Wisconsin, Madison; Barbara Whitney of the Space
Science Institute, Madison, Wis.; Rémy Indebetouw of the University of Virginia,
Charlottesville; and Christer Watson of Manchester College, Ind. NASA’s Jet
Propulsion Laboratory, Pasadena, Calif., manages the Spitzer mission for NASA’s
Science Mission Directorate, Washington. Science operations occur at the Spitzer
Science Center at the California Institute of Technology, also in Pasadena. For

Exoplanet HAT-P-7b in Cygnus (7 mmag depth)

Dear friends,

Last night I was blessed with very good transparency as well as good
seeing
which was a
godsend, for I sat down to pursue the transit for exoplanet HAT-P-7b
in Cygnus
and whose
depth is a meagre 7 mmag. With a magnitude of 10.460 for the parent
star (GSC
3547:1402)
before first contact, we have a new magnitude of approximately 10.467
during the
four-hr
transit.

I am very happy to present you with the resultant light curve and
which is available at http://www.perseus.gr/Astro-Photometry-HAT-P-7-20080603.htm
comprised of 413 data points (first light curve) and 84 five-point
medians (second light curve). The dynamic duo, my AP160 and AP1200GTO,
came through once again in a most impressive fashion and in spite of
the fact that the five-hr session started with my target below 40d.

This result is somewhat of a letdown in the sense that my next target
in a few days will be for a target with a 10 mmag depth and which
should be a relative breeze.

Clear skies!

Anthony.

Venus at superior conjucntion – the anti-transit

It’s been interesting following the progress of Venus toward superior
conjuction over the last few weeks in the images from SOHO. It has now
appeared in the LASCO C2 view, and will apparently pass behind the Sun in a
few days. I was thinking of this as an anti-transit, when I realized we were
almost exactly halfway between the last transit of Venus (6/8/2004) to the
next one (6/6/2012). Given that the orbits of Venus and Earth are nearly
circular, it makes perfect sense that at this halfway point, Venus would be
almost exactly on the far side of the Sun. I love it when I find a bit of
order in the Universe.
