Sorry about the multiple posts if they annoy you, but I wanted to reach
members who may not have joined the observers yahoo group.
We have the north bay of the shed undergoing installation of an
automatic garage door opener. Please bear with us for a while as the
various parts get installed. I'll post a detailed progress report in
the observers group as re Shed North Bay.
Please don't store anything on top of the parts we are using, or remove
any parts, or undo any work that has been done. Small common hardware
such as nails or wood screws won't be missed but it may not be easy to
tell what is a customized screw or pin that can't be replaced.
Thanks,
-Jim E.
While I may be going out on a limb here and run the risk of
“going off topic”, I feel it is important to clarify remarks made
by Sen. John McCain (R-AZ) during last night’s 2nd
presidential debate. During his rambling and often disjointed remarks, Senator
McCain made reference on 2 separate occasions to an “overhead
projector” and to a “planetarium projector” that Senator
Obama had obtained earmarked funds for. To be clear, the projector in question
is Adler’s famous Zeiss Mark VI planetarium projector, not an
“overhead projector”. The Adler Planetarium in Chicago, one of America’s oldest and most popular
planetariums, had sought federal funds from the *entire* Illinois congressional delegation to replace
the projector and refurbish the facility. The Adler Planetarium is a facility
widely used by the inner city students and schools of Chicago and is certainly a worthy expenditure
of taxpayer funds. I, as a citizen of NY and a US Taxpayer, have no problem
with my federal tax dollars funding such a facility and do not consider it
“pork”. The following is the Adler Planetarium’s official
response to Senator McCain’s irresponsible and misleading comments: http://www.adlerplanetarium.org/pressroom/pr/2008_10_08_AdlerStatement_aboutdebate.pdf
.
I have also uploaded this document to the group’s archive.

The following excerpt from the referenced article in Yahoo (http://news.yahoo.com/s/ap/20080920/ap_on_re_eu/eu_switzerland_particle_collider)
needs to be clarified: “Gillies said the sector that was damaged will
have to be warmed up well above the absolute zero temperature used for
operations so that repairs can be made — a time-consuming process.”
The LHC does *not*
operate at absolute zero. Absolute Zero, while defined as a state of
matter devoid of any energy, is not achievable in any realm, naturally or
artificially. Quantum Theory holds that there would always be a small probability
of some fluctuation and that there is no truly quiescent state of matter.
The temperature and density of Intergalactic Space is the coldest and most
rarified in all of nature. Remember the CMB? The Blackbody
temperature of this radiation is 2.3 K; the density of Intergalactic Space is approximately
equal to the average density of the universe: 1 Hydrogen atom per cubic meter,
a density much more rarefied than what can be achieved artificially. The
IGM (Intergalactic Medium), the occasional filaments of gas that exist between
galaxies, is about 10 to 100 times more dense than the average temperature of
the universe. While the lowest stated temperature achievable at the LHC
is between 4.5 and 1.9 K, sustaining this very low temperature is exceedingly
difficult due to energy requirements and the tolerances imposed on the vacuum seals
and equipment. All other variables being equal, temperature is
proportional to pressure; lowering the pressure has the corresponding effect of
lowering the temperature. The very low temperature of liquid Helium (~4
K) and the requirement that vacuums better than 10^-10 Torr be maintained over
a significant circumference are difficult to sustain. The vacuum of
Interstellar Space is between 10^-13 and 10^-14 Torr, a value between 1,000 and
10,000 times more rarified than what is obtainable artificially.
On another note concerning the LHC; Sadly, one
individual in India has already taken her life because of [irresponsible]
reports in the press that when they throw the switch at CERN and power-up the
LHC, the earth may be swallowed-up by a (micro) Black Hole spawned by the LHC.
This has to be the worst case of irresponsible and ignorant journalism. When
brought up to full power (~14 Tev), the mass equivalence (E=MC^2) of that
energy is on the order of 2x10^-23 kg, about 15 thousand times more massive
than a single proton (~1.6x10^-27 kg). According to current theory and
models, the smallest Black Hole should be no less than 3 solar masses (NASA’s
Rossi X-ray Timing Explorer recently discovered the smallest black hole to date
with a mass of 3.8 solar masses and a diameter of 24 km). 3.8 solar
masses is 3.7x10^57 times more massive than a single proton and 2.5 x 10^53
times more massive than the maximum energy (14 Tev) of the LHC. Now, when
someone asks you whether the earth will end by Black Hole, as a number of my
students have asked me, you can answer them with confidence by saying that
there is a greater chance of the earth being hit by a 10 km asteroid tomorrow
than being swallowed-up by a black hole spawned by the LHC.
Any statements in the regular press concerning new advances
in Physics, Astronomy and Astrophysics need to be read with a certain
circumspection. A word to the wise: always question statements and
pronouncements in the press from people who were trained as journalists, not
scientists.

PHOTO CAPTION: By Bob Lutz's own admission, it was the introduction
of the Tesla Roadster that caused General Motors to re-evaluate its stance on
electric-drive cars and set in the motion an intense race to bring to market
the world's first modern, OEM-built, range-extended electric car, the Chevy
Volt.
The Potential for Charging Electric Vehicles with Improved
Efficiencies in Outdoor Lighting
Since the
invention of the electric light, a pall of light pollution has been cast over
the land, effacing our vistas of the stars from the night time sky. Over the last
twenty years since the formation of the International Dark Sky Association,
knowledge of how to preserve this natural heritage through improving outdoor
lighting has grown by leaps and bounds. We know with certitude today how
replacing standard Semi Cut Off (SCO) lighting fixtures with Full Cut Off (FCO
) outdoor lighting fixtures with thirty percent (30%) reduction in size can put
the same amount on light on the ground while keeping light out of the sky.
Safety and visual acuity at night can be dramatically improved with the general
use of Full Cut Off lighting.
Full Cut
Off ( FCO ) lighting fixtures do this by limiting all the light from a fixture
to below the horizontal plane. They also limit the emission of light to only a
few percentile from between the horizontal plane and 15 degrees below it. This
keeps light out of the glare zone which improves visual acuity at night. The
electrical efficiencies to be gained by this improvement in fixture technology
are at least thirty percent. Quite simply if you are not throwing away thirty
percent of the light in useless directions, then fixtures can be downsized by
same amount, and still put the same amount of light on the ground with good
optics.
Other
efficiencies exist to be exploited. They are eliminating fixtures where not
really needed, eliminating time of use, or when not needed, and bi level
ballast for reducing lighting levels in the morning hours when parking lots are
not really being utilized. I would estimate that fully addressing all these
aspects would reduce outdoor lighting electrical consumption by at least 50%,
but for the purposes of this article we will consider only the more easily
reached 30% reduction mentioned above for the full use of FCO fixtures.
Consider this 30% figure to be the low hanging fruit of outdoor lighting
efficiencies.
One of
the major concerns about the coming technology of Plug In Hybrid Electric drive
vehicles and pure Electric only Vehicles, is how many of them can be charged
using off peak electricity without major investments in new power plants, and
in the grid. It is the position of this paper that unexploited electrical
efficiencies in lighting in general and outdoor lighting specifically could
power millions of these new electric vehicles if these inefficiencies in
lighting were to be addressed. Addressing them would not only release wasted
electricity for other valuable uses such as charging electric vehicles off
peak, but doing so would save billions of dollars for municipalities and cities
nationwide.
Since
lighting tends to be binned in size increments of thirty percent this paper
will use the 30% figure as a goal for improvements in outdoor lighting. In
brief a 70 watt light can provide the same light on the ground as a 100 watt
for example, if the former is FCO, and the latter is not. Outdoor lighting is
by definition using off peak power being switched on by photo sensors after
sunset switching off before sunrise.
In the UnitedState
of America
lighting accounts for twenty two percent (22% ) of all electrical consumption.
Outdoor lighting uses eight (8% ) of that 22% total, or only 1.77% of all
electricity. This is a vast amount of power amounting to 58,000 GWh/year.
Saving 30% of this power through the proper abatement of light pollution with
FCO lighting downsized by 30% would liberate 17,400 GWh/year of off peak
electricity.
Just how
many electric cars could this saved power recharge for how many miles. We will
use the new GM Series Hybrid Electric Car the Volt for a baseline. The Volt is
designed to have a 40 mile electric drive only range, then a small internal
combustion engine will start to recharge the batteries if needed. We will
consider a 40 mile daily drive for five days a week using battery power only.
The power storage of the Volt is 16 KWh’s and GM has said they have
designed this vehicle to deplete the batteries no more then 50% before
recharging. That would mean 8 KWh’s are available for this stated 40 mile
range. Assuming an 80% charging efficiency this would mean it would take 10 KWh’s
of grid power to recharge the GM Volt. At this rate the Volt would use 50
KWh’s of electricity a week, or 2,600 KWh’s a year for 10,600 miles
of electric powered driving. I am not saying everyone would operate their
vehicle in this manner, only that this is the potential this technology has.
All this
is strait forward enough with 17,400,000,000 KWh/year of freed up electricity
through addressing lighting pollution abatement, how many GM Volt’s can
we recharge yearly. Dividing the total electrical saving by the GM volt’s
yearly consumption yields the amazing figure of 6,692,000 GM Volt’s that
can be operated without building one new power plant. This scenario has the
potential to electrify over 71 billion passenger miles reducing the global
climate change impact of the oil that would normally be used for this purpose.
Considering
100 mile range electric only vehicles we could simply divide the vehicle
figures by 2.5 which yielding 2.67 million electric only 100 mile range cars
with the same platform efficiencies. Since such vehicle would not carry a IC
engine they actually would perform better then this. Over 1.3 million 200 mile
range electric only vehicles could be operated on this kind of power alone if
they were to be commonplace.
How could
the U.S. Federal government achieve these results. Number one thing, ban the
Semi Cut Off light except for special uses like indoors. Mandate Full Cut Off
Lighting for all outdoor applications. Set maximum level of illumination for
gas stations, convenience stores, etc., to 50 FCO foot candles (fc ), and to 30
fc for dark surrounds. Ban the Hg Vapor light period. Limit highway and parking
lots to 2 fc and specify bi-level ballasted lighting for parking lots. Ban HID
Flood lighting with articulations above 25 degrees. Set lumen’s output
caps for specific mounting heights to no more then 24 times the square of the
mounting height with exceptions for high activity areas. Limit car dealerships
to 20 fc. Ban the incandescent light bulb. Mandate all residential fixtures
capable of operating lamps over 15 watts CF be FCO. Reward utilities for
promoting off peak efficiencies and shifting power to the transportation
sector.
If nearly
7 million GM Volts can be operated on saved electricity from outdoor light done
right, and nearly 2.7 million electric only vehicles can be recharged from the
same amount of power, imagine what eight times this amount of freed up power
could do from commercial and industrial lighting. If the United States were ever to get
serious about doing something about global climate change and our hemorrhaging
of petrodollars overseas we would be doing this. We are beginning to see is the
vast potential for electrical efficiencies to power our transportation fleet
well into the future on more benign sources of power. The off peak grid has a
great amount of elasticity, in that we can exploit current wasteful practices
for new power.
Power is
now being wastefully thrown away to known inefficiencies. In short, all of this
could be done for a large net negative cost in money, with pay backs as short
as five years to our society, and greatly reduced environmental impacts. This
is what we would be doing in the USA in a rational world where
government regulated for the public benefit.

Joint Dark Energy Mission Public Website and Science Coordination Group
With this broadcast, the National Aeronautics and Space Administration
(NASA) and the Department of Energy (DOE) announce the opening of a
new public website for the Joint Dark Energy Mission (JDEM), a joint
NASA/DOE space-based mission to investigate dark energy. The purpose
of this website is to provide "one-stop shopping" for all public
information and documents regarding the mission that is generated by
or for the two agencies. This will be the primary conduit by which the
agencies will communicate on JDEM issues with the science community.
This broadcast also announces a Call for Letters for individuals to
apply for membership in the JDEM Science Coordination Group (SCG). The
SCG will aid in establishing preliminary science requirements for a
JDEM facility and will work in coordination with the JDEM Project
Office to develop a pre-conceptual design for JDEM that meets the
mission?s programmatic constraints. The function and responsibilities
of this Group are described in more detail in the Call for Letters and
Charter which are posted on the JDEM website.
The website URL is http://jdem.gsfc.nasa.gov. It will become open to
the public at 10am EDT on Friday, September 12. The initial contents
will include the following:
(1) An exchange of letters between the two agencies stating the
overarching principles of cooperation on JDEM;
(2) A Call for Letters to solicit expressions of interest to serve on
the JDEM SCG, along with the SCG's Charter.
We urge all those involved in dark energy research with an interest in
JDEM to refer to this website.

Last night I was out working on the C14 at Custer. We are making progress. As usual, I will first discuss the positives and then the negatives.
Positives:
1. I was able to get the ACP automation system working. Keep in mind that there is alot involved, including plate-solving, auto-focusing, camera control, scope/mount control, etc.
Negatives:
1. The big problem still is the mechanical jumping and skipping of the mount. Jeff is going to speak to a mechanical engineer this week and get back to me. Hopefully we will be able to replace the grease on the worm and worm gear. Jeff feels that the grease there is no good anymore. That will involve nothing more than taking out the worm/motor combo in the RA housing, removing the grease with a solvent and toothbrush, and reapplying the new grease. Hope that will work. If not, then the mount has to either be sent back to Celestron or be taken apart.
2. I wasn't able to test the guiding system. I was about to, but then the sky clouded over. Due to the mechanical problems, I'm not optimistic with guiding.
Hopefully next week we can apply new grease and test the guiding.
Cherry Springs State
Park, Pa.,
received a special designation from the International Dark-Sky Association
because it has little light pollution.
(Dave Wymer)
This
afternoon, I attended a briefing on Capitol Hill about light pollution, a
subject that has filled many of my
notebooks. A representative of a major utility company, a conservation
scientist, a medical researcher, and other experts addressed a roomful of
congressional staffers in an effort to move the federal legislature to take action
against wasteful artificial lighting. Several states, including Texas, and hundreds of towns across the country,
including Homer Glen, Ill.,
have taken measures to control how much light gets cast into the sky rather
than onto targets on the ground. But the federal government has not made rules
aimed at limiting light pollution.
One
presenter, biologist Travis Longcore of the Urban Wildlands Group in Los
Angeles, ran through a litany of species that are harmed by misdirected
illumination, such as migratory birds, which can become disoriented and crash
fatally into lighted towers, and sea turtle hatchlings, which can be lured away
from the sea—and to their inevitable death—by illuminated roadways.
Another presenter, David Blask of the Bassett Research Institute in Cooperstown, N.Y.,
focused on explaining why nocturnal illumination is linked to health problems
in one important species in particular: humans.
I've covered the harmful
effects of artificial light elsewhere, so I won't rehash them here. But
it's worth mentioning that the June 18 issue of the Journal of the National Cancer Institute
describes yet another scientific advance in our understanding of why women who
work in lighted conditions during the night have elevated rates of breast
cancer. Eva Schernhammer of HarvardMedicalSchool
and her colleagues report that postmenopausal women who have low levels of
melatonin, a hormone that the body makes primarily when it's dark, are more
likely to develop breast cancer.
Schernhammer
previously led a study that found that women who work at night, such as nurses
who work the graveyard shift, are at high risk of breast cancer. That finding,
published in 2001, was among the first scientific hints that frequent exposure
to light at night can lead to health problems. Since then, shift work has been
labeled a probably human carcinogen by a branch of the World Health
Organization.
Tonight, I read in the Custer Comment that George Vrattos had passed away.
I am greatly saddened by this.
Some few months ago, Rosanne and I took George out to a Sunday dinner; he
had told me that he was being moved in just a few days to his son's house
somewhere down south- I forget where, exactly.
We took him to a favorite Greek restaurant in Sayville, where we arranged
for him to order his big lamb dinner entirely speaking in Greek. Both he
and the restaurant's owner had a great time conversing. We spent a couple
of hours all together that afternoon, and when I brought him back to his
house we said good-bye to each other with the bond of the firmest handshake
as George was known for.
He was a steadfast soul, one who stood by me and confided in me as I did in
him for many years and through many vicissitudes of our lives. We often
joked about the religious calendars, and he and I called each other for me
to announce the dates of Greek Orthodox holidays and George to announce the
Jewish Orthodox ones- we had a lot of fun with the calendars and their
amusing complexities.
We shared a LOT of laughs as well as moments of introspection, and many good
nights at the telescope, too. George and I got 109 out of 110 Messier
objects at the Custer Messier Marathon of 1984. I still have somewhere the
"log" from that famous all-nighter.
I will miss George very much. His simulated crusty demeanor easily revealed
a man with a heart as big and affable as his smile. He was a fearless yet
realistic fellow who was at home with microwave electronics and engineering,
sound recording, and speaking a seemingly limitless number of foreign
languages.
Thank you.

WorldWide Telescope
Brings Space Exploration to Earth
A
service free of charge from Microsoft lets students and lifelong learners tour
the night sky using high-resolution images from the world’s best land-
and space-based telescopes.
REDMOND, Wash. — May 12, 2008 — The final
frontier got a bit closer today as Microsoft Corp. officially launched the
public beta of its WorldWide Telescope, which is now available at http://www.worldwidetelescope.org.
WorldWide Telescope is a rich Web application that brings together imagery from
the best ground- and space-based observatories across the world to allow people
to easily explore the night sky through their computers. WorldWide Telescope
has been eagerly anticipated by the astronomical and educational communities as
a compelling astronomical resource for students and lifelong learners, and as a
way to make science fun for children.
“The
WorldWide Telescope is a powerful tool for science and education that makes it
possible for everyone to explore the universe,” said Bill Gates, chairman
of Microsoft. “By combining terabytes of incredible imagery and data with
easy-to-use software for viewing and moving through all that information, the
WorldWide Telescope opens the door to new ways to see and experience the
wonders of space. Our hope is that it will inspire young people to explore
astronomy and science, and help researchers in their quest to better understand
the universe.”
The
application itself is a blend of software and Web 2.0 services created with the
Microsoft high-performance Visual Experience Engine, which allows seamless
panning and zooming around the heavens with rich image environments. WorldWide
Telescope stitches together terabytes of high-resolution images of celestial
bodies and displays them in a way that relates to their actual position in the
sky. People can freely browse through the solar system, galaxy and beyond, or
take advantage of a growing number of guided tours of the sky hosted by
astronomers and educators at major universities and planetariums.
“WorldWide
Telescope brings to life a dream that many of us in Microsoft Research have
pursued for years, and we are proud to release this as a free service to anyone
who wants to explore the universe,” said Curtis Wong, manager of
Microsoft’s Next Media Research Group. “Where is Saturn in the sky,
in relation to the moon? Does the Milky Way really have a supermassive black
hole in the center of the galaxy? With the universe at your fingertips, you can
discover the answers for yourself.”
The
service goes well beyond the simple browsing of images. Users can choose which
telescope they want to look through, including the Hubble Space Telescope, the ChandraX-RayObservatoryCenter, the Spitzer Space
Telescope or others. They can view the locations of planets in the night sky
— in the past, present or future. They can view the universe through
different wavelengths of light to reveal hidden structures in other parts of
the galaxy. Taken as a whole, the application provides a top-to-bottom view of
the science of astronomy.
“Users
can see the X-ray view of the sky, zoom into bright radiation clouds, and then
cross-fade into the visible light view and discover the cloud remnants of a
supernova explosion from a thousand years ago,” said Roy Gould, a
researcher at the Harvard-SmithsonianCenter for Astrophysics.
“I believe this new creation from Microsoft will have a profound impact
on the way we view the universe.”
Microsoft
Research has formed close ties with members of the academic, education and
scientific communities to make WorldWide Telescope a reality. NASA along with other organizations
coordinated with Microsoft Research to provide the imagery, provide feedback on
the application from a scientific point of view, and help turn WorldWide
Telescope into a rich learning application.
Microsoft’s
mission to make the universe accessible to everyone was begun years ago by
renowned Microsoft Senior Researcher Jim Gray. WorldWide Telescope is built on
top of Gray’s pioneering development of large-scale, high-performance
online databases including SkyServer and his contributions to the Sloan Digital
Sky Survey, a project to map a large part of the Northern sky outside of the
galaxy. Microsoft Research is releasing WorldWide Telescope as a service free
of charge to the astronomy and education communities as a tribute to Gray with
the hope that it will inspire and empower kids of all ages to explore and
understand the universe in an unprecedented way.

CASSINI IMAGING LEAD SCIENTIST TO PROVIDE COSMIC PERSPECTIVE FOR
MILLIONS AROUND THE GLOBE
When the worldwide film event known as Pangea Day launches this
Saturday, May 10, Cassini imaging team leader and veteran imaging
scientist, Carolyn Porco, will be present to provide an inspiring
perspective on humanity's place in the cosmos.
Pangea Day is a global event intended to bring the world together
through film and will link six locations around the world for a live
program of powerful films, live music and visionary speakers. The entire
four-hour program will be broadcast in seven languages to millions of
people worldwide on television, on the internet and over mobile phones.
Known for her passionate advocacy of space exploration, Porco was asked
by event organizers to kick off the program with a grand and sweeping
view of humankind's cosmic place, providing the context for the human
stories and songs that will be featured on Pangea Day.
"This will truly be one of those inspiring, hands-across-the-water
events that will be remembered for years to come," said Porco, "...a day
when each of us will be able to see the world through someone else's
eyes. I encourage everyone who hopes for peace to come to the world to
tune in."
Other speakers include CNN's Christiane Amanpour, Queen Noor of Jordan,
journalist Lisa Ling and former-soldiers-turned-peace-activists from
many conflicts across the globe. There will also be musical performances
and the airing of the 24 short films that were chosen from thousands of
entries from over 100 countries around the world.
Porco will present from Los Angeles. The other live broadcast venues are
in Cairo, Kigali, London, Mumbai and Rio de Janeiro.
American audiences will be able to take part in Pangea Day beginning at
2pm Eastern Daylight time (11am Pacific Daylight Time) on May 10 by
viewing the live broadcast on television, online, in public and private
venues and on mobile phones. The event will be broadcast live on cable
television in the United States by Current TV and YouTube will be
donating its homepage to the event. The program will be available
globally on a full-screen broadband web-stream courtesy of Akamai and
MSN in some 100 countries, including China, India, Indonesia, Malaysia,
Australia all of Latin America, the US, Britain, France, Italy, and
Ireland. It will also be streamed on the event website
http://www.pangeaday.org.
Additional information about the event and how to watch and/or
participate is available at the event website.
Images from NASA's Cassini and Voyager spacecraft are available online
at http://ciclops.org.
The Cassini Imaging Central Laboratory for Operations (CICLOPS) is the
operations center for the imaging team of the international
Cassini-Huygens mission to Saturn -- a cooperative project of NASA, the
European Space Agency and the Italian Space Agency. The imaging team
consists of scientists from the U.S., England, France, and Germany.

Thank you for writing back, Rebecca. I realize that you are writing to an
eclectic audience. The main point of my response, which you've articulated, was
that we could save tons of CO2 and megawatts of power if we simply installed
lighting more intelligently. My colleagues and I in the IDA don't advocate a
"dark ground", just a "dark sky". In addition to addressing other important
environmental concerns that are beyond the scope of this response or your
original article, by installing or retrofitting existing fixtures, fully
shielded lighting offers a substantial savings, a savings that is realized by
using a bulb with a smaller carbon footprint (lower wattage) that is used at
peak efficiency (reflectors in conjunction with a good optical design are a
design paradigm for any full-cutoff fixture) with that savings being passed
along to the municipal ratepayers (we, the taxpayers!). I realize that you're
limited to how much you can publish and I appreciate you taking the time to
write back. I welcome additional comments from the authors if they choose to
comment further.
Thanks again.

Subject: Re: EO Comment: Cities at Night: The View from Space
Dear Thomas,
Thank you for writing to us. Believe me when i say that on a personal
level, I coulnd't agree more with you about light pollution. I grew up
in rural West Virginia, and among the things i most treasure about going
home is the darkness of the night sky and the view of the stars and the
Milky Way. When the neighbor across the way put up a street light, it
made me want to reach for a BB-gun. I understand the concerns about the
impact of nighttime lighting on people's health, wildlife, and energy
consumption. I am certainly among those would be willing to sacrifice
convenience for a better view of the night sky.
however, those lights /are/ a sign of human presence, and while I can't
speak for the astronauts who took these images, I can /imagine/ the
feeling of.. affection and connectedness, might be the best
description...that an astronaut might feel at seeing city lights from
the darkness of space. I can imagine those astronauts feeling the same
way i have felt on occasions when calamity or inattention has found me
in the woods after dark, unprepared, and how i felt when i finally
caught a glimpse of the lights of "civilization." The astronaut
photography team may have been trying to share that feeling with people.
The topics you raise are important concerns, but they were simply beyond
the scope of this short article. I will forward your comments to the
authors, and they may contact you separately if they have anything more
to add.
Sincerely,
Rebecca Lindsey

You could have mentioned: the consumptive burning of fossil fuels necessary to
produce the hundreds of megawatts of wasted energy that are lighting up the sky
are a huge contributor to global climate change, the disrupted sleep patterns
and circadian rhythms of countless individuals, the disruption of the migratory
patters of many species of birds and animals, the link between artificial
lighting and certain forms of cancer, the destruction of the nighttime sky, once
known in a bygone era as “the greatest show on earthâ€. Gone is that
show, replaced with the garish and insipid lights of Las Vegas, a city with the
dubious honor of being “the brightest spot on earthâ€. This honor is
a sad testimony to what society values. Located in the great US Southwest,
within a few hours driving time of the nation’s (and, in some respects,

a dichotomy, to the breathtaking beauty of the night sky as seen from the very

Re: Cities at Night: The View from Space
I read with interest your column with the above captioned title. Being
published under the auspices of NASA one would think that there would be
some reference to the "effect" nighttime lighting has insofar as the parent
website is, ostensibly, published from a "Green" perspective. Although the
"Barn-door tracker" is good idea and necessary one, no mention is made on
the effects those bright cities have on the environment. From an
environmental perspective, it is breathtaking in the extreme that nowhere is
a reference made as to "why" you could see those cities from perch "above"
them.
With global climate change unequivocally linked to human activity, the
question begs asking: "Why are we lighting up the nighttime sky?" You could
have mentioned: the consumptive burning of fossil fuels necessary to produce
the hundreds of megawatts of wasted energy that are lighting up the sky are
a huge contributor to global climate change, the disrupted sleep patterns
and circadian rhythms of countless individuals, the disruption of the
migratory patters of many species of birds and animals, the link between
artificial lighting and certain forms of cancer, the destruction of the
nighttime sky, once known in a bygone era as "the greatest show on earth".
Gone is that show, replaced with the garish and insipid lights of Las Vegas,
a city with the dubious honor of being "the brightest spot on earth". This
honor is a sad testimony to what society values. Located in the great US
Southwest, within a few hours driving time of the nation's (and, in some
respects, the world's) center for astronomy, Las Vegas stands in stark
contrast, a dichotomy, to the breathtaking beauty of the night sky as seen
from the very same desert on which it was built.
Never in your column is there a challenge as to "why" we feel compelled to
light up kilometer after kilometer of open highway in the middle of the
desert.
It's high time the environmental movement recognize, let alone mount an
effort to combat, the ongoing destruction of the nighttime environment by
uncontrolled and runaway light pollution. Sadly, with all their fervor,
scant few are aware of this obvious assault on a very important part of our
natural environment with the corresponding and concurrent squandering of
precious natural resources. Ironically enough, it is reversible but largely
ignored or unknown.

Cities at Night: The View from Space
Astronauts onboard the International Space Station capture nighttime
photographs of city lights, spectacular evidence of humanity's existence,
our distribution, and our ability to change our environment.
