Unique Telescope Facility Opens In Swiss Biosphere

Alpine Swiss Village

In the easternmost part of Switzerland near the Italian border, lies a pristine area of land ranging from 1,400 to 3,173 meters above sea level. It encompasses 172,400 hectares of forests, alpine grasslands and bare rocks or screes that are strictly protected and not inhabited. Each year, around 50 researchers from Switzerland and abroad carry out scientific studies in the area. A research committee is responsible for the coordination of the various projects, such as hydrology, meteorology, biodiversity, ecology. Now, another specialty is arriving in this area in form of a private endeavor – astronomy.

AAV Lue-Stailas is a new center for amateur astrophotography in the eastern Alps of Switzerland. Built on a sunny terrace at 1935 m (6300 ft) and facing south into the beautiful valley of Muestair, the center’s prime geographical location benefits from excellent sky conditions with about 250 clear nights a year. Thanks to its rigorous protection policy, Val Muestair was able to keep much of its original rural and natural habitat. This will soon be honored by the regions participation in a new high-alpine UNESCO Biosphere Reserve in the European Alps, the Val Muestair/Swiss National Park Reserve. AAV Lue-Stailas will collaborate with this unique “Biosfera”-Project in order to bring its pristine skies to the public. The center will open in March of 2009, the International Year of Astronomy.

AAV Lue-Stailas is the brainchild of Václav and Jitka Ourednik who hold both a PhD in neuroscience and have been studying the regenerative capacity of the central nervous system for over 20 years. While pursuing competitive research and publishing in foremost scientific journals, they present their scientific results at international symposia and organize professional meetings and seminars. But what’s happening in Switzerland has been born of the unique love of both the micro and macro cosmos. Says Jitka, “The views through a microscope can be remarkably similar to vistas in the universe imaged through a telescope such as the Hubble Space Telescope (HST) or simulated with computers according to current cosmological theories.”

Microscope VS. TelescopeInner Space or Outer Space?

In order to promote public awareness for the need to protect the natural habitat and dark skies, Václav and Jitka have decided to make their life-long hobby a profession and create a center for amateur astrophotography in Europe. Their search for the best possible location for hosting a unique telescope facility lasted several years. Finally, being both fond of the Swiss Alps, they chose a sunny terrace at an altitude of 2000 m in the county of Lue in eastern Switzerland for the creation of the Alpine Astrovillage Lue-Stailas. Says Vaclav, “Recent statistics show that the global interest in astronomy increases every year dramatically. Moreover, people are not only interested in astronomy and astrophotography but they also realize how important their contribution is in the preservation of our global natural habitat, which also includes the protection of dark night skies by a strict control of light pollution.”

At Alpine Astro Village, each living quarters/studio will have its own automated dome, telescope and imaging equipment, which can be, if needed, operated from the studios. Another treat of the center are its two robotic telescopes in Australia for remote imaging of the southern skies.. Yet, although the main purpose of the site is astrophotography, and there will also be telescopes set up for visual exploration for public activities like star parties and AAV club activities, there’s just a little more to this sphere than the astronomy angle:

“One of the unique aspects of AAV Lue-Stailas is that we strive to maintain and profit from the contrast of embedding our center of modern life style and high-tech equipment within the historical heritage of the region . This allows the visitors to fully enjoy and capture the beauty of the local night sky while having the opportunity to enjoy all the treasures of the valley and its vicinity during the day” say the Ouredniks, “The region provides limitless opportunities for daytime nature walks, biking tours, or demanding hiking expeditions. In winter, downhill skiing is less than one car-hour away (famous resorts such as Davos, Pontresina, St-Moritz…)and cross-country ski tracks are right at our center’s door step. We also strongly suggest visiting of the neighboring villages in the valley and beyond. You will find beautiful, traditional, and historic architecture, led by the Monastery of Saint John in Muestair, a United Nations Educational, Scientific and Cultural Organization World Heritage Center dating from the 8th century and famous for its frescos from the times of Charlemagne. A visit to Val Muestair and AAV Lue-Stailas will stay forever in your memory.”

And so will meeting the lovely, giving Vaclav and Jitka Ourednik.

Podcast: Missions to Mars, Part 1



With last month’s safe arrival of the Phoenix Mars Lander, Mars enthusiasts breathed a collective sigh of relief… phew. Now it’s time to search for evidence of organic molecules in the ice at Mars’ north pole. But this is just the latest in a long series of missions sent to the Red Planet. Let’s have a history lesson, and look back at the missions sent to Mars, successful and unsuccessful.

Hubble Zooms In On Coma Galaxy Cluster

The Coma Cluster is one of the densest known clusters of galaxies, containing thousands of elliptical and spherical star systems. The entire cluster is huge, more than 20 million light-years in diameter. It’s also very far away, over 300 million light years distant. But no telescope brings the Coma Cluster closer than the Hubble Space Telescope, and a new Hubble image has captured the magnificent starry population in one area of the Coma Cluster with the Advanced Camera for Surveys.

The above Hubble image focuses on an area that is roughly one-third of the way out from the center of the whole cluster. One bright spiral galaxy is visible in the upper left of the image (see below for a close-up of this galaxy). It is distinctly brighter and bluer than the galaxies surrounding it. A series of dusty spiral arms appears reddish brown against the whiter disc of the galaxy, and suggests that this galaxy has been disturbed at some point in the past. The other galaxies in the image are either elliptical galaxies, S0 (s-zero) galaxies or background galaxies that are far beyond the Coma Cluster sphere.

Ellipticals are featureless “fuzz-balls,” pale golden brown in color and contain populations of old stars. Both dwarf and giant ellipticals are found in abundance in the Coma Cluster.

Farther out from the centre of the cluster there are several spiral galaxies. These galaxies contain clouds of cold gas that are giving birth to new stars. Spiral arms and dust lanes “accessorise” these bright bluish-white galaxies, which have a distinctive disc structure.

S0 (S-zero) galaxies form a morphological class of objects between the better known elliptical and spiral galaxies. They consist of older stars and show little evidence of recent star formation, but they do show some structure — perhaps a bar or a ring that may eventually give rise to more disc-like features.


This image zooms in on one area of the new Hubble image, the stunning Lenticular galaxy (in the lower left of the first image) with numerous background galaxies visible as well.

The cluster’s position in space – near the Milky Way’s north pole— places it in an area not obscured by dust and gas, making it easily visible from Earth.

Equipment Review: Meade 8X42 Travel Binoculars

My Mother always told me that if I couldn’t say something good about somebody, that I shouldn’t say anything at all. Well, after a few weeks of using a pair of Meade 8X42 Travel Binoculars, I guess it’s about time I said something… I just hope you want to hear it.

First Impression of the Meade 8X42 Travel Binoculars

I opened the box and there they were… a pair of Meade binoculars in a plastic blister pack like you’d find hanging on a peg in your nearby discount department store. I couldn’t help but ask myself if I was going to get the same quality as a Meade department store telescope, but I knew I had to be fair. After all, you can’t judge a cake by its frosting, right? Darn, right.

So, I open them up and examined them. According to their advertising blurb; “They are light and portable, and include a carrying case and neck strap.” Well, they’re right about that. These 8X42 binoculars certainly are light. Actually, they’re probably the lightest pair I’ve ever held that had that kind of aperture. Carrying case? Check. Neck strap? Check. Now for the binoculars themselves…

“A rubber coated exterior helps protect your Meade Travel binoculars from bumps and dings, and offers a slip-proof grip.” Right again, the tubes are rubberized and I will give them credit – they definitely are easy to securely grip. Let’s see now. It says “Optics Fully Coated”. Yep. They are. At least the surfaces I’m looking at are coated and apparently well done. What’s next? Right eye diopter? Gotcha’ . It’s there, too… And functional. Interpupillary distance? Check. Spreads wide… Goes to narrow. Everything seems to be functioning perfectly… So let’s have a look!

Viewing Through the Meade 8X42 Travel Binoculars

Well, surprise surprise! With or without eyeglasses, I have no problem hitting focus and the Meade 8X42 Travel Binoculars have sweet eye relief. It boasts closes focus of 21 feet, but I actually got it down to around 10 feet with a nice image. According to their advertising; “Meade 8X42 Travel Binoculars offer bright, clear images for a host of observing opportunities, from nature viewing and birding to sporting events and travel.” Well, let’s just see, huh?

So, out we go. During the daylight I was picking up bright, crisp images of birds, well defined looks at distant objects and am pleased to announce that the claim of “8X is the perfect compromise for those who want to hand-hold their binoculars for an extended period of time but want more magnification than low power models” is correct. The light weight does make them easy to hold and to steady. But, what about twilight viewing? Again, I’m impressed. I was watching deer a good thousand yards away and I could easily distinguish their different coat markings. Yeah, Meade!

Now, what about astronomical implications? Not bad on the Moon. I can see crater detail and hold them steady. Jupiter? Steady enough to see two jovian moons. Star clusters? Yep. M44 is nice and crispy. M67 isn’t resolved, but then I didn’t expect it to be. Globular clusters show up nicely. Again, they don’t resolve – but it’s not the binoculars fault. Galaxies? Yes. M81 and M82 were fine. M51 was faded, but there… and M65 and M66 took some aversion but could be seen. Double stars? Mizar and Alcor…. mmmm… ok. Cor Caroli? Again, just ok. All in all? The Meade 8X42 Travel Binoculars perform well in all applications.

All applications, but one…

Traveling With the Meade 8X42 Travel Binoculars

One of the reasons I enjoy binoculars so much is that I do travel. Something that’s only about the size of a good book is easy to tuck in between your clothes in your suitcase and send up the luggage ramp into the airplane. And this is just what I did with the Meade 8X42 Travel Binoculars. After all, my laptop has been halfway around the world and back in just this same manner.

Ummm… Apparently Meade just needs to take the word “Travel” out of their description.

The laptop in its suitcase arrived fine – but the binoculars in the other didn’t. Absolutely nothing fragile inside the same suitcase was damaged in any way, but the moment I tried to use the Meade 8X42 Travel Binoculars after traveling I got double images. Folks, when you see two perfectly focused images while looking through a pair of binoculars? Something has definitely gone afoul inside the tomato. I readjusted the interpupillary distance. I readjusted the right eye diopter. I readjusted the focus. I tried covering one lens – and then the other. The result? Either optical tube showed a crisp, clean image… But not together. Test number two – give them to someone else to look through. Guess what? Yeah. They saw the same thing. Two images. Just a little bit of active use and this pair of binoculars lost their collimation.

In the long run, maybe you won’t experience the same thing I did with the Meade 8X42 Travel Binoculars. Maybe I just got that one in every hundred pair that had a screw loose. Maybe the suitcase they were in got handled a lot rougher than what it looked like. Maybe both of sets of eyes went bad in a short period of time. Maybe it won’t happen to you… But maybe… Maybe it will.

Sorry, Ma. I really tried.

What Do You Do If Someone Blows Up Your Satellite? Call a Space Lawyer

Artist impression of an anti-satellite missile (Jeremy Cook/Popular Mechanics)

As space travel becomes routine and private enterprise gets a foothold in low Earth orbit, it is becoming clear that specialists in the field of space law are required. Until now, lawyers here on the surface have extended their knowledge into space, but there will be a time when terrestrial lawyers will need to be superseded by a space equivalent. For example space lawyers could wrangle who is accountable for the space debris left behind after a satellite gets shot down. What happens if a nation accidentally (or deliberately) destroys another nation’s spy satellite? Does this cause retaliation with global consequences or can the dispute be easily settled in “Space Court” with the help of space lawyers? These are extreme examples, but space lawyers may eventually become a part of everyday life for manned excursions into the cosmos. To mark the beginning of this new era of law, the first space law student graduated from the University of Mississippi on Saturday…

Michael Dodge from Long Beach, Mississippi, graduated last weekend with a special distinction with his degree from the National Center for Remote Sensing, Air and Space Law, University of Mississippi. This marks the beginning of a new era for the legalities in the space travel as Dodge is the first ever US space lawyer.

The university is unique in that it offers the only dedicated aerospace law curriculum in the US which is accredited by the American Bar Association. The degree requires courses in US space and aviation law, international space and aviation law, and remote sensing. Dodge also had to carry out independent research, contributing to the publication of the Journal of Space Law.

Once I came to the law school, I read that there was an attorney here that specialized in space law. After that, I became curious as to why space needed regulation, and how legal regimes could be constructed to govern such an expanse.” – Michael Dodge

The future promises to be good business for Dodge, as more and more technology and private corporations are launched into orbit, disputes will be commonplace. Recently, the Chinese and US shoot down of satellites caused international condemnation; the left-over debris is considered to be a huge risk to the future of space travel. In this case, what would happen if a multi-million dollar satellite were damaged by an orbiting piece of space junk? Could the satellite owner take legal action against the organization that littered low Earth orbit? Even mundane disputes such as confrontations on the International Space Station would require a specialist’s knowledge in the laws of space.

Many people would argue that there are already too many lawyers here on Earth, but it looks like space lawyers will be a necessary part of mankind’s big step into a new legal frontier…

Phoenix Will Try New “Sprinkle” Technique

Phoenix “vibrates” to move soil through a screen.

New motto for the Phoenix spacecraft: If at first you don’t succeed, then dust yourself off and try again. Since the Martian soil is proving to be a challenge for the Mars lander, engineers will try a new technique to try delivering the frozen arctic soil into the TEGA, or the Thermal and Evolved-Gas Anaylzer, designed to bake and sniff samples to identify key ingredients in the soil. The soil is clumping together, and won’t pass through a screen that brings it to the ovens on board the spacecraft. Engineers operating the Robotic Arm on Phoenix Lander are testing a revised method they are calling the sprinkle technique.

“We’re a little surprised at how much this material is clumping together when we dig into it,” said Doug Ming a Phoenix science team member from NASA’s Johnson Space Center, Houston.

Engineers commanded the spacecraft to vibrate the screen for 20 minutes on Sunday but detected only a few particles getting through the screen, not enough to fill the tiny oven below.

“We are going to try vibrating it one more time, and if that doesn’t work, it is likely we will use our new, revised delivery method on another thermal analyzer cell,” said William Boynton of the University of Arizona, lead scientist for the instrument.

The arm delivered the first sample to TEGA on Friday by turning the scoop over to release its contents. The revised delivery method, which Phoenix is testing for the first time today, will hold the scoop at an angle above the delivery target and sprinkle out a small amount of the sample by vibrating the scoop. The vibration comes from running a motorized rasp on the bottom of the scoop.

Phoenix used the arm Sunday to collect a soil sample for the spacecraft’s Optical Microscope, so look for images of that procedure soon. Today’s plans include a practice of the sprinkle technique, using a small amount of soil from the sample collected Sunday. If that goes well, the Phoenix team assembled at the University of Arizona plans to sprinkle material from the same scoopful onto the microscope later this week.

The Phoenix team also discussed this picture, showing a spring on the ground near a footpad of the spacecraft. It came from Phoenix itself, when the biobarrier was opened to free the robotic arm back on May 30, the sixth Martian day of the mission.

Can Light be “Squeezed” to Improve Sensitivity of Gravitational Wave Detectors?

Visualization of a massive body generating gravitational waves (UWM)

The search is on to detect the first evidence of gravitational waves travelling around the cosmos. How can we do this? The Laser Interferometer Gravitational-Wave Observatory (LIGO) uses a system of laser beams fired over a distance of 4 km (2.5 miles) and reflected back and forth by a system of mirrors. Should a gravitational wave pass through the volume of space-time surrounding the Earth, in theory the laser beam will detect a small change as the passing wave slightly alters the distance between mirrors. It is worth noting that this slight change will be small; so small in fact that LIGO has been designed to detect a distance fluctuation of less than one-thousandth of the width of a proton. This is impressive, but it could be better. Now scientists think they have found a way of increasing the sensitivity of LIGO; use the strange quantum properties of the photon to “squeeze” the laser beam so an increase in sensitivity can be achieved…

LIGO was designed by collaborators from MIT and Caltech to search for observational evidence of theoretical gravitational waves. Gravitational waves are thought to propagate throughout the Universe as massive objects disturb space-time. For example, if two black holes collided and merged (or collided and blasted away from each other), Einstein’s theory of general relativity predicts that a ripple will be sent throughout the fabric of space-time. To prove gravitational waves do exist, a totally different type of observatory needed to be built, not to observe electromagnetic emissions from the source, but to detect the passage of these perturbations travelling through our planet. LIGO is an attempt to measure these waves, and with a gargantuan set-up cost of $365 million, there is huge pressure for the facility to discover the first gravitational wave and its source (for more information on LIGO, see “Listening” for Gravitational Waves to Track Down Black Holes). Alas, after several years of science, none have been found. Is this because there are no gravitational waves out there? Or is LIGO simply not sensitive enough?

The first question is quickly answered by LIGO scientists: more time is needed to collect a longer period of data (there needs to be more “exposure time” before gravitational waves are detected). There is also strong theoretical reasons why gravitational waves should exist. The second question is something scientists from the US and Australia hope to improve; perhaps LIGO needs a boost in sensitivity.

The laser "squeezer" equipment (Keisuke Goda)

To make gravitational wave detectors more sensitive, Nergis Mavalvala leader of this new research and MIT physicist, has focused on the very small to help detect the very big. To understand what the researchers are hoping to achieve, a very brief crash course in quantum “fuzziness” is needed.

Detectors such as LIGO depend on highly accurate laser technology to measure perturbations in space-time. As gravitational waves travel through the Universe, they cause tiny changes in the distance between two positions in space (space is effectively being “warped” by these waves). Although LIGO has the ability to detect a perturbation of less than a thousandth of the width of a proton, it would be great if even more sensitivity is acquired. Although lasers are inherently accurate and very sensitive, laser photons are still governed by quantum dynamics. As the laser photons interact with the interferometer, there is a degree of quantum fuzziness meaning the photon is not a sharp pin-point, but slightly blurred by quantum noise. In an effort to reduce this noise, Mavalvala and her team have been able to “squeeze” laser photons.

Laser photons possess two quantities: phase and amplitude. Phase describes the photons position in time and amplitude describes the number of photons in the laser beam. In this quantum world, if the laser amplitude is reduced (removing some of the noise); quantum uncertainties in laser phase will increase (adding some noise). It is this trade-off that this new squeezing technique is base on. What is important is accuracy in the measurement of amplitude, not the phase, when trying to detect a gravitational wave with lasers.

It is hoped that this new technique can be applied to the multi-million dollar LIGO facility, possibly increasing LIGO’s sensitivity by 44%.

The significance of this work is that it forced us to confront and solve some of the practical challenges of squeezed state injection—and there are many. We are now much better positioned to implement squeezing in the kilometer-scale detectors, and catch that elusive gravitational wave.” – Nergis Mavalvala.

Where Is the New Horizons Spacecraft?

Even though New Horizons is the speediest spacecraft ever to travel through our solar system, it still has a long way to go on its voyage to Pluto and the Kuiper Belt. However, New Horizons hit an interplanetary milepost yesterday, June 8, by crossing the orbit of Saturn. At 1.5 billion kilometers or 935 million miles (10.06 astronomical units) distant, that’s a mission’s worth of space for most spacecraft. But for New Horizons, it’s just another interplanetary point on its voyage to the outer reaches of our solar system. As a testament to New Horizons’ speed, the spacecraft set a record for the fastest transit to Saturn by any spacecraft, making the trip in two years and four months. Voyager 1, the previous record holder, made the journey in approximately three years and two months.

Still aiming for its arrival at the Pluto/Charon system in July of 2015, New Horizons’ mission managers tell us the spacecraft is healthy, and in electronic hibernation. After a productive two-week series of system checks, maintenance activities, and software and command uploads, New Horizons is humming through the outer solar system at 65,740 kilometers per hour (40,850 mph). The team expects to keep the spacecraft in hibernation until Sept. 2.

Although the first 13 months of the mission kept the New Horizons team pretty busy, through its encounter with and gravity assist from Jupiter in February 2007, the next few years will probably be fairly quiet for the mission’s scientists and engineers.

In a previous interview, Alan Stern, New Horizons’ Principle Investigator told Universe Today, “The middle years will be long and probably, and hopefully, pretty boring. But it will include yearly spacecraft and instrument checkouts, trajectory corrections, instrument calibrations and rehearsals for the main mission.” During the last three years of the interplanetary cruise mission, Stern said teams will be writing, testing and uploading the highly detailed command script for the Pluto/Charon encounter. The mission begins in earnest approximately a year before the spacecraft arrives at Pluto, as it begins to photograph the region.

As New Horizons crossed Saturn’s orbit yesterday, the ringed planet was nowhere to be seen, as it was more than 2.3 billion kilometers (1.4 billion miles) away from the spacecraft.

And speaking of the Voyager spacecraft (way back in the first paragraph), Voyagers 1 and 2 are at the edge of the Sun’s heliosphere some 100 AU away, and are the only spacecraft operating farther out than New Horizons.

The next big milepost on New Horizons’ journey? Crossing the orbit of Uranus, on March 18, 2011.

Hanny’s Voorwerp – Still Alive and Kicking….

Hanny's Voorwerp

Back a few month’s ago, we had an article about Galaxy Zoo. In essence, it’s a type of consortium that studies galaxies and works towards classifying them. In the process of studying the images, they made a rather unusual discovery… One that’s still around.

According to the Galaxy Zoo blog: “Ever since it was first identified, Hanny’s Voorwerp has grabbed the attention of the Zookeepers and everyone else who comes across it. One reason we’ve been successful in getting such a wide range of observations over just a few months (and therefore why posts on here have been delayed!) has been that colleagues seem to find it equally compelling. So what is it? Our current best guess goes something like this:

A hundred thousand years ago, a quasar blazed behind the stars which would have already looked recognizably like the constellation Leo Minor. Barely 700 million light-years away, it would have been the nearest bright quasar, shining (had anyone had a telescope to look) around 13th magnitude, several times brighter than the light of the surrounding galaxy. This galaxy, much later cataloged as IC 2497, is a massive spiral galaxy which was in the process of tidally shredding a dwarf galaxy rich in gas – gas which absorbed the intense ultraviolet and X-ray output of the quasar and in turn glowed as it cooled. But something happened to the quasar. Whether it turned off, dropped to a barely simmering level of activity as its massive black hole became starved for gas to feed its accretion, or it was quickly shrouded in gas and dust, we don’t see it anymore. But we see its echo.”

But that was months ago. Is Hanny’s Voorwerp still alive and kicking? You betcha’. Astrophotographer Joe Brimacombe took this week’s image of the Voorwerp (Dutch for “what the heck is that?”) on May 25, 2008. Like Joe’s own interest, Galaxy Zoo didn’t stop searching out the meaning of Hanny’s Voorwerp, either. They kept right on photographing and analyzing. According to Bill Keel:

“At this point, we know that the object is rich in highly ionized gas. There is continuum light, especially at the northern tip, but the emission lines are so strong that we can as yet say little about its continuum structure. The high ionization might suggest shock ionization or photoionization by an active galactic nuclei, which would have to be much brighter than any we see in the neighborhood. If the AGN is in IC 2497, it must be highly obscured from our direction but not toward the gas. (It may be significant that the cloud lies near the galaxy’s projected minor axis). The FIRST survey at 20 cm shows weak emission from the cloud and a significant radio source in IC 2497. We are now pursuing further imaging, UV, and X-ray detections to work out what we are seeing here. Whatever it is, it seems to be unique in the SDSS imaging survey. Chris Lintott has queried the database and, after winnowing out imaging artifacts, found no objects with u-g and g-r colors within 0.15 magnitude of what we see in Hanny’s Voorwerp.

Our working hypothesis is that Hanny’s Voorwerp consists of dust and gas (maybe from a tidally disrupted dwarf galaxy) which is illuminated by a quasar outburst within IC 2497, an outburst which has faded dramatically within the last 100,000 years.”

What ever it might truly be is still somewhat a mystery… But it’s a great summer-hot object!
