Slight Lunar Eclipse Friday Evening

The last Lunar Eclipse or Eclipse of the Moon for 2013 will be a minor Penumbral Eclipse of the Moon on Friday evening (2013 October 18). Unlike a Total or Partial Eclipse of the Moon, a Penumbral Eclipse of the Moon is more difficult to notice, because only a partial shadow of the Earth falls on the Moon. Unlike a Solar Eclipse or Eclipse of the Sun, an Eclipse of the Moon is safe to view with the naked-eye, binoculars, or a telescope.

Friday's Penumbral Eclipse of the Moon will be visible for most viewers on our planet (except Australia, Japan, Pacific Ocean islands, a large portion of Alaska, most of Siberia, and a small portion of northeastern China.). However, in the Americas it will be visible as the Moon is rising, while in most of Asia it will be visible as the Moon is setting.

Although NASA describes Friday's eclipse as "a relatively deep penumbral eclipse with a magnitude of 0.7659," do not expect a darkened Moon, as might be seen in other Total or Partial Lunar Eclipses. It will simply appear a wee bit darker than a normal Full Moon.

As North American viewers will see this eclipse shortly after sunset, and while the Moon is rising, this will make it even more difficult to notice any shading on the Moon. While the Moon is rising, light from the Moon has to travel through a greater amount of Earth's atmosphere to reach a viewer's eyes. And, at this time, the Earth's atmosphere is not completely dark, as the Sun has just recently set.

The event will probably not be visible to most people until about 66 percent of the Moon's disk is immersed in the Earth's penumbra shadow. This is estimated to occur between 7:30 and 8:10 p.m. Eastern Daylight Time (23:30 October 18 to 0:10 October 19 Coordinated Universal Time); the time of greatest eclipse is 7:50:16.9 p.m. Eastern Daylight Time (23:50:16.9 Coordinated Universal Time). Then a dusky shading of the southern half of the Moon could be visible, depending on atmospheric conditions and the ability of a viewer to detect minor shading.

All Lunar Eclipses occur at the time of a Full Moon. This month, the Penumbral Eclipse of the Moon comes on the day of the Hunter's Moon: 7:38 p.m. Eastern Daylight Time (23:38 Coordinated Universal Time). The Hunter's Moon often occurs when many leaves have fallen off of the trees and the harvesting of most crops has been completed. Hence, with a bright Full Moon appearing shortly after sunset, tree leaves no longer blocking the moonlight, and fields cleared of crops, it created the best time to hunt for meat, to store for the long Winter ahead.

Colorful Fall Foliage: Astronomy Affects Nature

http://0.tqn.com/d/pittsburgh/1/0/p/4/moraine2-lg.jpg

The colors of Fall are reflected in Lake Arthur of Moraine State Park,
in north suburban Pittsburgh. Moraine State Park is named for the glacial
moraines that cover its land. The Park marks the approximate, greatest 
southerly extent of travel of the glaciers, during the last glacial period.

The second half of October marks both the end of the growing season, as well as the peak in colorful Fall foliage in the Pittsburgh Quad-State Region: Western Pennsylvania, Northern West Virginia, Eastern Ohio, and Western Maryland. Although these came a few weeks earlier, in the higher elevations of the Allegheny Mountains portion of the region.

The annual change in color of leaves, from the ubiquitous greens of Spring and Summer to the yellows, golds, oranges, reds, crimsons, purples, and browns of many deciduous trees and shrubs in the Autumn, is one of the greatest visible effects of Astronomy on the natural world we live in. The increasing length of darkness, each day in Autumn, is the primary cause of this color change.

Planet Earth has a 23.44-degree tilt in its north-south axis to the plane of its orbit around the Sun. Consequently, as the Earth revolves around the Sun, a different portion of the planet each season of the year receives the most direct sunlight. The Northern Hemisphere receives the most direct sunlight in the Spring and Summer months, while the intensity of sunlight diminishes during the Autumn until the beginning of Winter, when the length and intensity of sunlight is at a minimum.

It is the long nights and the lower intensity of energy coming from the Sun, due to the Sun's lower angle in the sky, during the Autumn and Winter months, that prevents the leaves from producing the nutrients needed by the plant. Hence, the leaves do not keep their green color and eventually fall-off. When the length and intensity of sunlight increases in the Spring months, trees and shrubs grow new, green leaves to harvest the sunlight into energy for the plant's needs.

After the Summer Solstice in June, each day the Earth's Northern Hemisphere receives less direct sunlight causing nighttime to become longer. However, as the most direct sunlight hits the Northern Hemisphere on the day of the Summer Solstice, and due to seasonal lag caused by large bodies of water on the Earth, the green leaves continue to flourish on most plants, except in areas of great drought. As the Earth reaches the point in its orbit around the Sun marking the Autumnal Equinox in the Northern Hemisphere, the less direct sunlight and longer nights become significant.

The production of chlorophyll in plants, during the Spring and Summer months when sunlight is more abundant, is used to manufacture food-sugars from sunlight through a chemical process known as photosynthesis. The chlorophyll pigment overwhelms other pigments in a plant's leaves; hence, the plant's leaves reflect a green color.

Plants prepare for the days when less sunlight will be available for food production by beginning to close-off the veins which carry fluids to and from their leaves. This a protective measure, to reduce the energy needs of the plant for the long Winter. Also, the tender leaves, in which the leave's fluids could easily freeze in sub-freezing temperatures, could hurt the plant and must be disposed-of. Hence, after the leaves change color, they fall off of the plant.

As days go by in the Fall with less intense sunlight available each day, chlorophyll production begins to slow down, stops, and eventually all chlorophyll is destroyed. Different species of trees and plants contain and produce different pigments, other than chlorophyll. Hence, when the chlorophyll is destroyed, the different pigments determine what colors will be unveiled in the leaves. The carotenoid pigment, which is always present in leaves, is then unmasked to show the yellow and gold colors of leaves, which remains pretty-much the same each year.

Weather, also influenced by the Earth's tilt on its axis and the amount of energy from the Sun received on different parts of the planet, has some additional effect on the intensity of pigment color in a leaf, each year, with temperature and moisture being the main influences.

Often the most brilliant displays of Fall color come when days are warm and sunny and nights are cool, but not below the freezing-point. In such days, chlorophyll continues producing sugars, but the closing of a leaf's veins traps these additional sugars in the leaves. This spurs the production of anthocyanin pigments, which results in leaves of dazzling red, purple, and crimson colors.

Although, if Autumn days are too warm, as we in the Pittsburgh region experienced in September, the leaves' veins may not close-off soon enough, and Fall colors will be slightly delayed or be less intense. A severe drought can also delay Fall colors. and, in some cases, result in leaves falling off branches prematurely.

Many areas of western and northern Pennsylvania, particularly in the Allegheny Mountains, have vivid displays of Fall color at this time of year. This is thanks to the astronomical effects of Earth, with the 23.44-degree tilt on its axis, revolving around the Sun..

Mystery Rocket Launch Seen From Space Station Explained



Last night, ESA/Italian astronaut Luca Parmitano posted some bizarre photos via his Twitter account from the International Space Station. A mystery rocket contrail could be seen rising above the Earth’s twilight horizon.

A missile launch seen from space: an unexpected surprise! pic.twitter.com/mbWI209ELv — Luca Parmitano (@astro_luca) October 11, 2013
This oddity was all the more strange as there were no scheduled launches by NASA (due to the government shutdown) or from any U.S. commercial spaceflight company. Russia and Europe also had no scheduled launches at that time. Still, something had been fired into space.

One photograph shows the wiggly trail of a white contrail — exhaust and water vapor created by a rocket’s passage through the atmosphere; odd pattern forming after being buffeted by high altitude winds. Then, in another dramatic snapshot, Parmitano posted a weird-looking cloud dominating the photograph caused by the rocket disintegrating over the Earth .

After doing some digging, Nancy Atkinson over at Universe Today found the answer, courtesy of the Russian Forces blog:

The Strategic Rocket Forces carried out a successful test launch of a Topol/SS-25 missile on October 10, 2013. The missile was launched at 17:39 MSK (13:39 UTC) from Kapustin Yar to the Sary Shagan test site in Kazakhstan. According to a representative of the Rocket Forces, the test was used to confirm characteristics of the Topol missile, to test the systems of the Sary Shagan test site, and “to test new combat payload for intercontinental ballistic missiles.”

Should We Worry About Comet ISON ?

Reporting for SpaceWatchtower 

Friends of the Zeiss, a non-profit organization which provides news and information to the public regarding Astronomy, Space, and related sciences, as well as promoting the history and preservation of Pittsburgh's original Buhl Planetarium and Institute of Popular Science, also provides a service whereby the public can send electronic mail inquiries regarding questions they have on Astronomy, Space, and related sciences, as well as seeking possible answers to an unknown object seen in the sky:

A recent public inquiry regarded the safety of Comet ISON, which is approaching the Sun and expected to arrive around Thanksgiving Day. The following is the response given to this question, by Glenn A. Walsh, Project Director of Friends of the Zeiss.

Should we worry about Comet ISON?

Do comets bring about solar storms when they come in near orbit with the sun?

Reply ---

From: Glenn A. Walsh

In 1910, thousands of people were scared because the newspapers reported that the comet tail of Halley's Comet, which was partially composed of cyanide gas, would brush along the Earth's atmosphere. The fear was that, somehow, the comet's tail would poison our atmosphere. Consequently, hucksters made money selling "comet pills" that were supposedly an antidote to the poisons from the comet's tail.

It was all bogus. Even the scientists of the day knew that there was no danger from the tail of Halley's Comet. And, the scientists did try to publicize that fact in the newspapers. But scare-mongering news reports always receive more attention from the public than a scientific news article.

The same is true regarding Comet ISON. Today, viral YouTube and other social media and Internet posts are drowning-out the scientific news articles debunking the fear-mongering reports about Comet ISON.

Astronomers have been watching Comet ISON for many months. The only question is whether Comet ISON will become a bright, naked-eye comet when it comes close to the Sun, or whether it will fizzle-out as spectacle in the sky. They are still not sure, so time will tell.

Comets do not create solar storms. Indeed, if Comet ISON was completely swallowed-up by the Sun (which is still one possiblity), the Sun would hardly notice it. Comets are balls of ice, dust, and perhaps some small rocky pieces which are much smaller than the Earth.

Solar storms can occur at any time, but are usually more frequent during the peak of the 11-year sunspot cycle. The Sun is nearing the peak of the current sunspot cycle, so it would not be unusual for a solar storm to break-out at this time. However, if a solar storm does break-out at the time Comet ISON encounters the Sun, around Thanksgiving Day, that would simply be a coincidence.

The following are recent articles, from the Friends of the Zeiss' SpaceWatchtower Blog, regarding Comet ISON and the current sunspot cycle:

With the Federal Government shutdown has also come the shutdown of most Government web sites, including the Internet web sites of NASA and other science-related agencies. However, some of the older Internet content of the web sites of these agencies may still be available, free-of-charge, through a unique Internet archive known as the "Wayback Machine."

The Wayback Machine is a digital archive of the World Wide Web and other information from the Internet, dating from 1996 to a few months ago. It is managed by the Internet Archive, a non-profit organization in San Francisco. Currently, there are about 240 billion pages archived.

Presently, it is necessary to know the actual Internet address of the web site or web pages of interest. Keyword-search is not available. However, in the case of shutdown Government web sites as well as other web searches of interest, a Google search can often give you the needed web address, or a web address close to the desired address for the web page of interest.

The Wayback Machine is named after the WABAC (pronounced way-back) machine, a time travel machine used by Mr. Peabody, a dog scientist with a bow-tie and eyeglasses, in the popular 1960s, children's television cartoon series Rocky and Bullwinkle.

New Mars Probe Launch Escapes Govt. Shut-Down

Mars MAVEN mission

NASA's next Mars-bound spacecraft was cleared for launch in spite of the federal government shutdown. (John Raoux / Associated Press / September 27, 2013)







MAVEN, set for launch between Nov. 18 and Dec. 7, will play a crucial role as a communications relay between Earth and the rovers Curiosity and Opportunity, Jakosky said. That’s a function currently carried out by two aging satellites, Mars Odyssey (launched in 2001) and the Mars Reconnaissance Orbiter (launched in 2005).

Had MAVEN not escaped the funding freeze, the team could have pushed a launch to Dec. 15 at the latest, about a week after the end of its official launch window, Jakosky said. But beyond that, Earth and Mars would have fallen out of ideal alignment.

Sat. Memorial Service for John McCarter, Buhl Planetarium Supporter

By Glenn A. Walsh
Reporting for SpaceWatchtower

A memorial service for a long-time supporter of Pittsburgh's original Buhl Planetarium and Institute of Popular Science, John W. McCarter who passed-away August 8 at age 81, will be held this Saturday (2013 October 5) at 10:30 a.m. EDT at the First Unitarian Church of Pittsburgh, which is located at 605 Morewood Avenue in the Oakland section of the City of Pittsburgh. A reception at the church follows the memorial service.

John, who lived most of his life in Pittsburgh and Dormont, was a music teacher in the Pittsburgh Public Schools, teaching in several city schools including Thadeus Stephens and John Morrow schools. He graduated from Oliver High School and studied music education at Indiana University at Bloomington.

John was born in Pittsburgh on 1931 October 24. Exactly eight years later, on 1939 October 24, came the dedication of Pittsburgh's original Buhl Planetarium and Institute of Popular Science, where he gained a life-long interest in Astronomy and the sciences during his youth. He eventually built his own telescope and used it to share his interest in stargazing with others.

John was a member of Friends of the Zeiss, a non-profit organization which provides informal Astronomy and Science education to the public, as well as promoting the history of Pittsburgh's original Buhl Planetarium and Institute of Popular Science.

John brought his 4-inch refractor telescope to the Mount Lebanon Public Library, on the evening of 2012 June 5, to assist with safe public viewing of the very rare Transit of the Planet Venus across the image of the Sun. Unfortunately, this public observing session, co-sponsored by Friends of the Zeiss and the Mount Lebanon Public Library, was preempted by clouds. However, the public was still able to observe the event via a NASA web-cast in a library meeting room.

In 2004, The Carnegie Library of Pittsburgh shut-down their very successful Three Rivers Free-Net (TRFN), which had provided free Internet web sites to Pittsburgh-area non-profit organizations. Anticipating this shut-down, immediately after the last day of operation of TRFN, David Tessitor and John McCarter co-founded the PittsburghFree.net. The PittsburghFree.net, which provides a very similar service as did TRFN, was completely financed by John McCarter.

The new free-of-charge, non-profit organization web site hosting service began with 40 web sites from TRFN. Today, the PittsburghFree.net hosts approximately 150 web sites of community-oriented groups and individuals.

Astronomical Calendar: 2013 October


One of the greatest natural effects of Astronomy on the Earth, caused by the revolution of our planet around the Sun combined with the 23.44-degree tilt of the Earth's axis, is the annual multi-color foliage in Autumn. This photograph shows the brilliant Fall foliage in Pennsylvania's Allegheny National Forest. (Image Source: Pittsburgh.about.com )
