Aerospace has opened the new Mt. Wilson Aerospace Facility for Integrated Optical Tests (MAFIOT) on the grounds of the Mount Wilson Observatory in Southern California. The official ribbon-cutting ceremony took place Tuesday, Oct. 21.

MAFIOT is designed to support a wide range of research in atmospheric laser propagation, atmospheric scattering, lidar, and laser communication. MAFIOT complements and greatly extends the capabilities of Aerospace’s original installation, the Mt. Wilson Optical Communications and Atmospheric Measurement (MOCAM) facility.

MAFIOT provides a flexible, low-cost solution for new technology assessment and experimentation in laser/lidar and astronomical physics. The facility houses a modular suite of instruments, including a series of cameras and their associated optics, capable of capturing visible through long wavelengths, all mounted on a 2-axis gimbal.

Together, MAFIOT and MOCAM provide a unique capability for experiments related to everything from laser communications to atmospheric and radiometric measurement, and ultimately are aimed toward the development of better tools and spaceflight systems. In addition, the site can host external experiments, act as a new technology test bed for customers, and serve as a ground station for various satellite experiments.

[The smaller scope apparently will get less use after the commissioning of the larger, and we’re looking into gaining access to it for the club.]
 

We’re still looking into scheduling another Mt. Wilson 60-inch session maybe in the Fall (we’ll see what our AEA budget allocation is).  But we must await the AEA budget allocation, as we’ve completely depleted our bank account.  Also, We’re also checking on the possibility of using Aerospace’s new 0.8m telescope at Mt. Wilson.


Oct. 23 Partial Solar Eclipse at AGO
A last-minute decision was made by Alan Olson & Mark Clayson to set up the H-alpha scope in the AGO mall to observe the partial solar eclipse near maximum.  A large sunspot group, some nice prominences and a filament were visible.  At least 2 or 3 dozen turned out to look, and here are some photos taken.


Club-Supported Star Party at WLAC
On Friday, Nov. 7 Mark Clayson & Nahum Melamed supported a star party for students of West L.A. City College & the public on their campus.  Nahum’s wife is on the faculty and arranged for us to bring our 10-inch telescope & giant binoculars.  It was a clear & warm evening, and a good turnout of a few dozen people, including a group of students from Mexico.  We looked at Uranus, Andromeda Galaxy, the Moon, and various stars, clusters & nebulae.  The GoTo feature of the 10-inch impressed all, and it was spot-on locating objects & centering them in the field of view.  Several took photos with their smart phones.  Someone else had an impressive virtual reality system with 3-D goggles & computer that allowed you to explore the solar system, etc.  The event is held each semester – twice a year – and we offered to support it in the future.
    
          

Astronomy Video(s) & Picture(s) of the Month
(from Astronomy Picture of the Day, APOD: http://apod.nasa.gov/apod/archivepix.html)


Video:  Sunspot Group AR 2192 Crackles http://apod.nasa.gov/apod/ap141022.html
Image Credit: 
Solar Dynamics Observatory, NASA
Explanation: One of the largest sunspot groups in recent years is now crossing the Sun. Labelled Active Region 2192, it has already thrown a powerful solar flare and has the potential to produce more. The featured video shows a time lapse sequence of the Sun in visible and ultraviolet light taken yesterday and incorporating the previous 48 hours. AR 2192, rotating in from the left, rivals Jupiter in size and is literally crackling with magnetic energy. The active Sun has caused some spectacular auroras in recent days, and energetic particles originating from AR 2192 may help continue them over the next week. Tomorrow, the Sun will appear unusual for even another reason: a partial solar eclipse will be visible before sunset from much of North America.


Video:  Sprite Lightning in Slow Motion http://apod.nasa.gov/apod/ap141013.html

Explanation: What causes sprite lightning? Mysterious bursts of light in the sky that momentarily resemble gigantic jellyfish have been recorded for over 25 years, but their root cause remains unknown. Some thunderstorms have them -- most don't. Recently, however, high speed videos are better detailing how sprites actually develop. The featured video is fast enough -- at about 10,000 frames per second -- to time-resolve several sprite "bombs" dropping and developing into the multi-pronged streamers that appear on still images. Unfortunately, thevisual clues provided by these videos do not fully resolve the sprite origins mystery. They do indicate to some researchers, though, that sprites are more likely to occur when plasma irregularities exist in the upper atmosphere.


Video:  A Total Lunar Eclipse Over Tajikistan http://apod.nasa.gov/apod/ap141005.html

Jean-Luc Dauvergne (Ciel et Espace); Music: Valère Leroy & Sophie Huet (Space-Music)
Explanation: If the full Moon suddenly faded, what would you see? The answer during the total lunar eclipse of 2011 June was recorded in a dramatic time lapse video from Tajikistan. During a total lunar eclipse, the Earth moves between the Moon and the Sun, causing the moon to fade dramatically. The Moon never gets completely dark, though, since the Earth's atmosphere refracts some light. As the above video begins, the scene may appear to be daytime and sunlit, but actually it is a nighttime and lit by the glow of the full Moon. As the moon becomes eclipsed and fades, the wind dies down and background stars can be seen reflected in foreground lake. Most spectacularly, the sky surrounding the eclipsed moon suddenly appears to be full of stars and highlighted by the busy plane of our Milky Way Galaxy. The sequence repeats with a closer view, and the final image shows the placement of the eclipsed Moon near the Eagle, Swan, Trifid, and Lagoon nebulas. Nearly two hours after the eclipse started, the moon emerged from the Earth's shadow and its bright full glare again dominated the sky. The next total lunar eclipse will occur this Wednesday.




In Green Company: Aurora over Norway

Explanation: Raise your arms if you see an aurora. With those instructions, two nights went by with, well, clouds -- mostly. On the third night of returning to same peaks, though, the sky not only cleared up but lit up with a spectacular auroral display. Arms went high in the air, patience and experience paid off, and the amazing featured image was captured. The setting is a summit of the Austnesfjorden fjord close to the town of Svolvear on the Lofoten islands in northern Norway. The time was early March. Our Sun has been producing an abundance ofpicturesque aurora of late as it is near the time of its maximum surface activity in its 11-year magnetic cycle.




Sunspots and Solar Eclipse

Explanation: A New Moon joined giant sunspot group AR 2192 to dim the bright solar disk during Thursday's much anticipated partial solar eclipse. Visible from much of North America, the Moon's broad silhouette is captured in this extreme telephoto snapshot near eclipse maximum from Santa Cruz, California. About the size of Jupiter, the remarkable AR 2192itself darkens a noticeable fraction of the Sun, near center and below the curved lunar limb. As the sunspot group slowly rotates across the Sun and out of view in the coming days its activity is difficult to forecast. But the timing of solar eclipses is easier to predict. The next will be a total solar eclipse on March 20, 2015.


Rosetta's Selfie 
Image Credit: 
ESA/Rosetta/Philae/CIVA
Explanation: This Rosetta spacecraft selfie was snapped on October 7th. At the time the spacecraft was about 472 million kilometers from planet Earth, but only 16 kilometers from the surface of comet 67P/Churyumov-Gerasimenko. Looming beyond the spacecraft near the top of the frame, dust and gas stream away from the comet's curious double-lobed nucleus and bright sunlight glints off one of Rosetta's 14 meter long solar arrays. In fact, two exposures, one short and one long, were combined to record the dramatic high contrast scene using the CIVA camera system on Rosetta's still-attached Philae lander. Its chosen primary landing site is visible on the smaller lobe of the nucleus. This is the last image anticipated from Philae's cameras before the lander separates from Rosetta on November 12. Shortly after separation Philae will take another image looking back toward the orbiter, and begin its descent to the nucleus of the comet.


NGC 4762: A Galaxy on the Edge 
Image Credit: 
ESA/Hubble & NASA
Explanation: Why is there a bright line on the sky? What is pictured above is actually a disk galaxy being seen almost perfectly edge on. The image from the Hubble Space Telescope is a spectacular visual reminder of just how thin disk galaxies can be. NGC 4762, a galaxy in the nearby Virgo Cluster of Galaxies, is so thin that it is actually difficult to determine what type of disk galaxy it is. Its lack of a visible dust lane indicates that it is a low-dust lenticular galaxy, although it is still possible that a view from on top would reveal spiral structure. The unusual stellar line spans about 100,000 light years from end to end. Near NGC 4762's center is a slight bulge of stars, while many background galaxies are visible far in the distance. Galaxies that appear this thin are rare mostly because our Earth must reside (nearly) in the extrapolated planes of their thin galactic disks. Galaxies that actually are this thin are relatively common -- for example our own Milky Way Galaxy is thought to be about this thin.


From the Temple of the Sun to the Temple of the Moon 
Image Credit & Copyright: 
Dave Lane
Explanation: What connects the Sun to the Moon? Many answers have been given throughout history, but in the case of today's featured image, it appears to be the plane of our Milky Way Galaxy. The 16-image panorama was taken in Capitol Reef National Park, Utah, USA where two sandstone monoliths -- the Temple of the Moon on the right and the Temple of the Sun on the left -- rise dramatically from the desert. Each natural monument stands about 100 meters tall and survives from the Jurassic period 160 million years ago. Even older are many of the stars and nebulas that dot the celestial background, including the Andromeda Galaxy. Tomorrow the Earth will connect the Sun to the Moon by way of its shadow: a total lunar eclipse will be visible from many locations around the globe.


Astronomy News:

NASA's hubble surveys debris-strewn exoplanetary construction yards

Published: Friday, November 7, 2014 - 04:47 in Astronomy & Space

NASA/ESA/G. Schneider/U. Arizona
Astronomers using NASA's Hubble Space Telescope have completed the largest and most sensitive visible-light imaging survey of dusty debris disks around other stars. These dusty disks, likely created by collisions between leftover objects from planet formation, were imaged around stars as young as 10 million years old and as mature as more than 1 billion years old. "It's like looking back in time to see the kinds of destructive events that once routinely happened in our solar system after the planets formed," said survey leader Glenn Schneider of the University of Arizona's Steward Observatory. The survey's results appeared in the Oct. 1, 2014, issue of The Astronomical Journal.


Once thought to be simply pancake-like structures, the unexpected diversity and complexity and varying distribution of dust among these debris systems strongly suggest these disks are gravitationally affected by unseen planets orbiting the star. Alternatively, these effects could result from the stars' passing through interstellar space.
The researchers discovered that no two "disks" of material surrounding stars look the same. "We find that the systems are not simply flat with uniform surfaces," Schneider said. "These are actually pretty complicated three-dimensional debris systems, often with embedded smaller structures. Some of the substructures could be signposts of unseen planets." The astronomers used Hubble's Space Telescope Imaging Spectrograph to study 10 previously discovered circumstellar debris systems, plus comparatively, MP Mus, a mature protoplanetary disk of age comparable to the youngest of the debris disks.
Irregularities observed in one ring-like system in particular, around a star called HD 181327, resemble the ejection of a huge spray of debris into the outer part of the system from the recent collision of two bodies.


New study finds oceans arrived early to Earth

Astronomers using NASA's Hubble Space Telescope have completed the largest and most sensitive visible-light imaging survey of dusty debris disks around other stars. These dusty disks, likely created by collisions between leftover objects from planet formation, were imaged around stars as young as 10 million years old and as mature as more than 1 billion years old. "It's like looking back in time to see the kinds of destructive events that once routinely happened in our solar system after the planets formed," said survey leader Glenn Schneider of the University of Arizona's Steward Observatory. The survey's results appeared in the Oct. 1, 2014, issue of The Astronomical Journal.

Earth is known as the Blue Planet because of its oceans, which cover more than 70 percent of the planet's surface and are home to the world's greatest diversity of life. While water is essential for life on the planet, the answers to two key questions have eluded us: where did Earth's water come from and when? While some hypothesize that water came late to Earth, well after the planet had formed, findings from a new study led by scientists at the Woods Hole Oceanographic Institution (WHOI) significantly move back the clock for the first evidence of water on Earth and in the inner solar system.

"The answer to one of the basic questions is that our oceans were always here. We didn't get them from a late process, as was previously thought," said Adam Sarafian, the lead author of the paper published Oct. 31, 2014, in the journalScience and a MIT/WHOI Joint Program student in the Geology and Geophysics Department.
One school of thought was that planets originally formed dry, due to the high-energy, high-impact process of planet formation, and that the water came later from sources such as comets or "wet" asteroids, which are largely composed of ices and gases.
"With giant asteroids and meteors colliding, there's a lot of destruction," said Horst Marschall, a geologist at WHOI and coauthor of the paper. "Some people have argued that any water molecules that were present as the planets were forming would have evaporated or been blown off into space, and that surface water as it exists on our planet today, must have come much, much later -- hundreds of millions of years later."
The study's authors turned to another potential source of Earth's water -- carbonaceous chondrites. The most primitive known meteorites, carbonaceous chondrites, were formed in the same swirl of dust, grit, ice and gasses that gave rise to the sun some 4.6 billion years ago, well before the planets were formed.
"These primitive meteorites resemble the bulk solar system composition," said WHOI geologist and coauthor Sune Nielsen. "They have quite a lot of water in them, and have been thought of before as candidates for the origin of Earth's water."
In order to determine the source of water in planetary bodies, scientists measure the ratio between the two stable isotopes of hydrogen: deuterium and hydrogen. Different regions of the solar system are characterized by highly variable ratios of these isotopes. The study's authors knew the ratio for carbonaceous chondrites and reasoned that if they could compare that to an object that was known to crystallize while Earth was actively accreting then they could gauge when water appeared on Earth.
To test this hypothesis, the research team, which also includes Francis McCubbin from the Institute of Meteoritics at the University of New Mexico and Brian Monteleone of WHOI, utilized meteorite samples provided by NASA from the asteroid 4-Vesta. The asteroid 4-Vesta, which formed in the same region of the solar system as Earth, has a surface of basaltic rock -- frozen lava. These basaltic meteorites from 4-Vesta are known as eucrites and carry a unique signature of one of the oldest hydrogen reservoirs in the solar system. Their age -- approximately 14 million years after the solar system formed -- makes them ideal for determining the source of water in the inner solar system at a time when Earth was in its main building phase. The researchers analyzed five different samples at the Northeast National Ion Microprobe Facility -- a state-of-the-art national facility housed at WHOI that utilizes secondary ion mass spectrometers. This is the first time hydrogen isotopes have been measured in eucrite meteorites.
The measurements show that 4-Vesta contains the same hydrogen isotopic composition as carbonaceous chondrites, which is also that of Earth. That, combined with nitrogen isotope data, points to carbonaceous chondrites as the most likely common source of water.
"The study shows that Earth's water most likely accreted at the same time as the rock. The planet formed as a wet planet with water on the surface," Marschall said.

While the findings don't preclude a late addition of water on Earth, it shows that it wasn't necessary since the right amount and composition of water was present at a very early stage.

"An implication of that is that life on our planet could have started to begin very early," added Nielsen. "Knowing that water came early to the inner solar system also means that the other inner planets could have been wet early and evolved life before they became the harsh environments they are today."

Earth's water is older than the sun


This is an illustration of water in our Solar System through time from before the Sun's birth through the creation of the planets.
Bill Saxton, NSF/AUI/NRAO
Carnegie Institution for Science President Matthew Scott

Water was crucial to the rise of life on Earth and is also important to evaluating the possibility of life on other planets. Identifying the original source of Earth's water is key to understanding how life-fostering environments come into being and how likely they are to be found elsewhere. New work from a team including Carnegie's Conel Alexander found that much of our Solar System's water likely originated as ices that formed in interstellar space. Their work is published in Science. Water is found throughout our Solar System. Not just on Earth, but on icy comets and moons, and in the shadowed basins of Mercury. Water has been found included in mineral samples from meteorites, the Moon, and Mars.

Comets and asteroids in particular, being primitive objects, provide a natural "time capsule" of the conditions during the early days of our Solar System. Their ices can tell scientists about the ice that encircled the Sun after its birth, the origin of which was an unanswered question until now.
In its youth, the Sun was surrounded by a protoplanetary disk, the so-called solar nebula, from which the planets were born. But it was unclear to researchers whether the ice in this disk originated from the Sun's own parental interstellar molecular cloud, from which it was created, or whether this interstellar water had been destroyed and was re-formed by the chemical reactions taking place in the solar nebula.
"Why this is important? If water in the early Solar System was primarily inherited as ice from interstellar space, then it is likely that similar ices, along with the prebiotic organic matter that they contain, are abundant in most or all protoplanetary disks around forming stars," Alexander explained. "But if the early Solar System's water was largely the result of local chemical processing during the Sun's birth, then it is possible that the abundance of water varies considerably in forming planetary systems, which would obviously have implications for the potential for the emergence of life elsewhere."
In studying the history of our Solar System's ices, the team -- led by L. Ilsedore Cleeves from the University of Michigan -- focused on hydrogen and its heavier isotope deuterium. Isotopes are atoms of the same element that have the same number of protons but a different number of neutrons. The difference in masses between isotopes results in subtle differences in their behavior during chemical reactions. As a result, the ratio of hydrogen to deuterium in water molecules can tell scientists about the conditions under which the molecules formed.
For example, interstellar water-ice has a high ratio of deuterium to hydrogen because of the very low temperatures at which it forms. Until now, it was unknown how much of this deuterium enrichment was removed by chemical processing during the Sun's birth, or how much deuterium-rich water-ice the newborn Solar System was capable of producing on its own.
So the team created models that simulated a protoplanetary disk in which all the deuterium from space ice has already been eliminated by chemical processing, and the system has to start over "from scratch" at producing ice with deuterium in it during a million-year period. They did this in order to see if the system can reach the ratios of deuterium to hydrogen that are found in meteorite samples, Earth's ocean water, and "time capsule" comets. They found that it could not do so, which told them that at least some of the water in our own Solar System has an origin in interstellar space and pre-dates the birth of the Sun.
"Our findings show that a significant fraction of our Solar System's water, the most-fundamental ingredient to fostering life, is older than the Sun, which indicates that abundant, organic-rich interstellar ices should probably be found in all young planetary systems," Alexander said.

Lecture: NASA’s Dawn Mission to the Asteroid Belt

The ambitious and exciting Dawn mission is one of NASA's most remarkable ventures into the solar system. After more than seven years of interplanetary spaceflight, the probe is just a few months away from the mysterious world Ceres. The spacecraft has already completed a spectacular exploration of Vesta. These were among the last uncharted worlds in the inner solar system prior to Dawn. They are the two most massive residents of the main asteroid belt, that vast collection of bodies between Mars and Jupiter. Ceres is so large that it is included in the category of dwarf planets, along with Pluto. The alien landscapes Dawn reveals provide humankind with a new perspective on the solar system. Remnants from the time that planets were formed, Ceres and Vesta hold clues that will help scientists understand the dawn of the solar system. Dawn orbited Vesta from July 2011 to September 2012 and returned astonishing views of this fascinating world. It is the only spaceship ever to orbit an object in the asteroid belt and is the first ever targeted to orbit any two extraterrestrial destinations. Such a mission would be truly impossible without the use of ion propulsion, a technology that has mostly been in the domain of science fiction. Dr. Marc Rayman will give a fascinating and entertaining presentation on the Dawn mission and its two exotic destinations as well as its use of ion propulsion. He also will share the excitement and profundity of controlling a robotic ambassador from Earth in deep space.
