I tweeted my way to ESO’s Very Large Telescope!

As an introduction, let’s just say that ESO – the European Southern Observatory – basically builds and operates the most advanced and powerful telescopes observing from our planet. For their 50th anniversary, they had the awesome idea to get one of their followers to tweet their way to the VLT… I came back a few days ago, and it was a beautiful life-changing experience.

Striking a pose on the VLT platform

The Very Large Telescope is located on top of a Chilean mountain, Cerro Paranal, at an altitude of about 2600 meters. Cerro Paranal is in the Atacama Desert, the driest region on Earth, 2 hours away by car from the nearest town. ESO chose the southern hemisphere to install their telescopes because it enables them to observe the center of the Milky Way and the Magellanic Clouds… and they chose Chile because the “seeing”, the quality of the observations is excellent. The atmosphere is very stable, the skies are almost always clear, there is no light pollution whatsoever.

Cerro Paranal is often nicknamed the astronomers’ paradise by those who visit it… and with reason; one of them even told me that if he was not married, he would never want to leave! The conditions up there are harsh, and of course observations last all night long, 365 days a year, but Paranal is nonetheless an amazing place to work and live. ESO did a great job when they built the Residencia,  which is beautifully integrated in the surrounding landscape. From the outside, it looks a bit like the underground lair of a James Bond villain… which may explain why the Residencia was chosen as a filming location for Quantum of Solace!

Cerro Paranal hosts 10 active telescopes. There are four telescopes with an 8.2-meters diameter mirror, named UT-1 through 4 and a.k.a. Antu (The Sun), Kueyen (The Moon), Melipal (The Southern Cross) and Yepun (Venus) in Mapuche language. There are also 2 survey telescopes, VST with a 2.6-meters and VISTA with a 4-meters mirror and 4 “small” ones, with “only” an 1.8-meters mirror (the auxiliary telescopes). Telescopes can be combined for specific observations using a process that is called Interferometry – which makes them even more powerful. The 4 auxiliary telescopes can be moved around to any of the 30 positions available on the platform, which opens an amazing range of observation possibilities. I think the only place where I can say it this here, among spacetweeps… I sure did not expect to be so emotionally moved by these gentle giants.

The telescopes are amazing pieces of technology… powerful, silent, and gorgeous in the chilean light – sunrise, daylight, sunset, darkness, moonlight… The view from and on the VLT platform is always breathtaking. Please check out check out my pictures here if youre not convinced yet!

On my last night at Cerro Paranal, I teamed with Henri Boffin – a renowned ESO astronomer- to image Thor’s Helmet, the NGC 2359 nebula… The observation was streamed live on ESO’s website as part of a six-hours broadcast, which I can only recommend you watch if you’re interested in astronomy. The picture we took is stunning! Mathieu (outreach team), Gabriel (astronomer), Claudio (shift supervisor) and I were also live from the VLT platform a few hours later for a Q&A session…

If I had to sum up this week in Chile… I had a great time, met a lot of people who are passionate about their work, and learned a lot about astronomy and ESO. And if you’d rather read the longer version, please check out my blog entries for this trip… available in both english or french!

Can you imagine that the mirror for the future E-ELT (European-Extremely Large Telescope) will be 39 meters wide?

In Memory of Colin Greenhalgh, April 29, 1957 – January 24, 2012

Canis Majoris, the “Big Dog” with open cluster galaxy M41 at its heart and the brilliant star, Sirius, pointing the way, is the appropriate constellation to watch for as we contemplate the loss of our friend and fellow Space Tweep, Colin Greenhalgh; known to us all as @OriginalColin on Twitter.

Colin lost his battle with a difficult illness on January 24, 2012 in Durham, UK. As the realization of his untimely passing spread through the Twitter community, it’s become wonderfully obvious that he was truly loved by so many and especially by his fellow Space Tweeps. Second only to his devotion to and love of dogs, especially rescued dogs, Colin returned the favor, and loved us back!

Growing up in England ensured that Colin was exposed to astronomy and related subjects at a very early age. Amateur astronomy and a working knowledge of the stars and constellations remains to this day an enviable element in British education, and that exposure nurtured an early love of all things “Space” in the young Colin. As many US tweeps have learned in their interaction with so many UK tweeps, this love of “looking up” instilled in youth, lasts a lifetime.

Before the end of the Space Shuttle Program, Colin, like the rest of us, participated enthusiastically in the excitement and electricity of following the launches and landings of the Space Shuttle in real time, with the Space Tweep Community (on at least two or more continents) through Twitter, and frequently through @SpaceFlightNow. But his love of space, fascination with space flight and knowledge of astronomy were not all that made Colin a likely member of the Space Tweeps. Colin was an all-round science geek! From Star Trek to Star Wars to “Apollo 13” to anything associated with NASA, or its counterpart the ESA; from the SDO and its warnings of oncoming CME’s and their spectacular aurora; to a deep love for and profound respect for those lucky enough to leave this planet and return to it he loved it all. That was Colin’s way.

It took the modern miracle of Twitter, and the community of tweeps who coalesced around the US Space Program and NASA, together with the tireless leadership of Jen Scheer (@flyingjenny) to bring forth the “Space Tweep Society.” It took about 5 minutes for Colin to sign up!

A charming story, shared by Colin’s beloved younger sister Ros, explains how an early adventure sealed the deal: Ros writes “ . . . I take enormous comfort knowing how much he loved the ‘company’ of his tweet friends and I was delighted when he went to London to meet some of them as this was a ‘big’ journey for him as he had very little money and rarely traveled. He couldn’t stop talking about it when he returned home. His love of Space started when he became friends with an American boy called Randy at the age of 14 (when he was visiting his Aunt in Seaham where we lived). Randy’s family invited him to Michigan for a holiday which included a trip to Florida and subsequent visit to the Space Centre. From that point on he was forever ‘hooked’ :) ” I think we can see that joy on Colin’s face in this photo!

One of Colin’s biggest thrills occurred this past year, when he traveled to London and met with @Craftlass, @SpaceKate, @leslieberg @herrea and @flyingjenny at The Lyric Pub. He’d traveled 270 miles south by train and, but for his lack of wings, could have flown back to Durham on his own!

His experience was memorialized by Jen’s presentation of treasured NASA patches and, of course, Space Tweep Society patches of which he was so proud! His tweet accompanying this picture was “You can’t just buy these. You have to be given them!” And he was.

Colin’s interests were so much deeper and broader than can be given proper due here. He was, first and foremost completely in love with “his” dogs! For reasons which no one can fail to understand, Colin was the trusted walker and care provider for dogs belonging to others, whether they were simply unable to spare the time, or away from Durham for days or weeks. There was almost nothing in his life that pleased him so much as to be out walking with them through the beautiful area of fields and streams not far from his home.

As you can see from the images above and the sunset following, even though he underplayed it, Colin had a talent and an eye for photography; a gift from his late father of whom he was very proud. His dad was a professional photographer and, in the days before the digital camera came along, film needed development. When he was old enough, Colin helped his dad in the darkroom and once mentioned that the experience drew him to the study of chemistry. That education eventually took him to Durham University, where he was a long time technician in the Chemistry Department.

Colin’s heart, his intelligence, his talent for snarky British humor, his progressive passions, his sheer charm – even his cranky “arse” moodiness made him so dear to so many of us. 54 years and change was not enough!

Next time you’re out and it’s clear, look up and find Canis Majoris. Colin is likely up there somewhere with his Big Dog.

1st European SpaceTweetup #Spacetacular!!

1st European SpaceTweetup #Spacetacular!!

On 18 September, the German Aerospace Centre (DLR, @dlr_en) and the European Space Agency (ESA, @esa) invited 60 lucky Twitter followers to the first European SpaceTweetup.  Among them some of our most prominent members, @flyingjenny, @herrea, @CraftLass, @travelholic, @amoroso, @marcozambi, @SpaceKate, @DrLucyRogers and @rocketman528. I (@akanel) was also lucky to be invited – and this was my first Tweetup ever!

The SpaceTweetup took place on German Aerospace Day at the joint DLR and European Astronaut Centre site in Cologne.  It was an amazing day, which not even the German grey and rainy weather could spoil!  …it did, of course, make our photographs a bit murky, but that’s about it!

The SpaceTweetup program was full and exciting.  So many thrills packed inside approx. 10 hours that could have easily been the object of two or more separate events.  For those who didn’t get to attend, a four hour (!) long selection of the best moments is available on ESA’s site.

The day started very excitingly.  We visited and learned about the SOFIΑ Project (Stratospheric Observatory for Infrared Astronomy), DLR and NASA’s impressive airborne telescope.  Mounted on a Boeing 747SP aircraft modified by L-3 Communications Integrated Systems, SOFIA has a 2.5 meter reflecting telescope, which makes measurements during flight!  High above the disturbances caused by Earth’s atmosphere, but also easily accessible for maintenance and modifications, SOFIA combines the advantages of space telescopes, like Herschel and Hubble, with the ease of ground based telescopes.

The science done on SOFIA is planned by the Universities Space Research Association (USRA) and the Deutsches SOFIA Institut (DSI) under the leadership of NASA Ames Research Centre.  Observing mostly in the far infrared, SOFIA will be used to study many different kinds of astronomical objects and phenomena, such as e.g. star birth and death, formation of new solar systems, identification of complex molecules in space (such as organic materials necessary for life), planets, comets and asteroids in our own solar system, nebulae and dust in galaxies and black holes at the centre of galaxies, helping to answer many fundamental questions about the creation and evolution of the Universe.

The Future of the James Webb Space Telescope

JWST

Image credit: NASA

Greetings Space Tweeps,

I just wanted to drop a quick line for all to see concerning the fate of the James Webb Space Telescope. JWST promises much for the field of Astronomy and science in general. It will be able to see far earlier into the history of the universe than ever before, provide help in examining extrasolar planets, and bring humanity answers (and indeed more questions) about our reality. Most importantly, it will provide science jobs, research and inspiration right here in the US of A. While its goals are noble, there is controversy about its cost. NASA has addressed the budgeting issue and put JWST back on track. Nevertheless, on Nov 18 2011, the US House of Representatives will be voting on that funding.

If it is of interest to you to #saveJWST then please see this link for more information. Also check out #saveJWST, #3×10, and #write4flight hashtags on Twitter.

If you do not support the telescope, then feel free to ignore this post. I do not wish to discuss the merits of JWST here. This is just a friendly reminder that you can do something to #savethistelescope .

Science and space travel are humanity’s two most important assets. The more people know about what NASA does the better off humanity will become.

The James Webb Space Telescope

Hello fellow members of the #spacetweepgeekdom !

It’s a great morning here. I am a #NASATweetup alum of the June 6, 2011 #NASATweetup @NASAJPL in California some weeks ago. It is a pleasure not only to be so much more involved with NASA now, but to interact with other spacetweeps. You truly are a people I grok.

I am writing this post for only one quick, simple reason. The James Webb Space Telescope is in danger of losing its funding. Congress will be voting in part to eliminate its funding this Wednesday July 13, 2011. If you are interested in the fight to prevent this, then I have some links for you:

I only want to bring this to your attention. Some of you no doubt are interested in this. Others may not think it is worth the time and effort to save JWST. That’s fine on both counts. If the above links are useful, then take them. If not, then please just ignore the post. There is no reason to have a discussion of the merits of saving/canceling JWST here on the Space Tweep Society website.

Thanks for your time, and do have a great day =)

Epic ISS Pass Last Night

Clear skys and mild temperatures and a bright ISS slicing right through the middle of the sky. Made for a perfect night to view the completed station. For the first time in my life I was able to make out the solar panels with a pair of binoculars. I snapped a few time exposures but didn’t take the time to set the camera. I was to busy talking to neighbors and explaining what they were seeing through the binoculars. It was a very exiting time. I shared my tweetup experience with all my neighbors who may now look up more often and remember that we have a presence in the sky. A million pound outpost circling the planet at over 17,000mph.

Celebrate St. Patty’s Day at the American Museum of Natural History – follow MESSENGER Spacecraft as it begins to orbit Mercury

MESSENGER Orbital Insertion of the Innermost Planet, Mercury

After flying nearly 5 billion miles over 6 years from Earth, the MESSENEGER spacecraft is scheduled to begin orbiting Mercury on March 17, becoming the first spacecraft to do so if successful. To date, MESSENGER’s three flybys of the innermost planet have yielded invaluable insights about Mercury, the smallest, densest, and least explored of the terrestrial planets.

The event will feature a live feed from MESSENGER operations center at Johns Hopkins University with Sean Solomon, director of the Department of Terrestrial Magnetism at the Carnegie Institution and principal investigator of the MESSENGER mission, and Museum scientists, who will discuss the mission, including the importance of understanding Mercury’s high-density composition. The Museum’s Digital Universe Atlas will be used to illustrate the path that MESSENGER traveled before entering Mercury’s orbit on the AstroBulletin screen.

The fate of the spacecraft—which will begin its rocket burn at 8:50 pm—won’t be known until after 10 pm.

WHEN: Thursday, March 17, from 8:30 to 10:15 pm Wine and beer will be available for purchase from the Starlight Café.

WHERE: Dorothy and Lewis B. Cullman Hall of the Universe, Fredrick Phineas and Sandra Priest Rose Center for Earth and Space. Enter at 81st Street.

ADMISSION: Free

Thank you to Ellen Evaristo of the American Museum of Natural History for the tip!

NASA Stardust craft to make Valentine’s night pass by comet

NASA Stardust craft to make Valentine's night pass by comet

(Cape Canaveral, FL) — A NASA spacecraft will make a Valentine’s night pass by a fast moving comet in the hopes of learning more about the icy rock.

The Stardust-NExT (New Exploration of Tempel) spacecraft is on a course to fly very close to the comet Tempel 1 on Monday at about 11:37 pm EST.

“Stardust-NExT is a mission to reuse the Stardust spacecraft to further the exploration of comet Tempel 1,” principle investigator Joe Veverka explained.

“Temple 1 was the target of Deep Impact. Deep Impact discovered that this is a most interesting comet,” Veverka added. “We want to see more of the surface and we also want to see what changes have occurred since Deep Impact went there five years ago.”

In a deep space ballet 209 million miles or 2.25 AU from earth, Stardust will both scientifically scan and photograph Tempel 1.

The two space objects are expected to fly to within 124 miles apart.

The mission’s project manager, Tim Larson, explained, “We want to extend the mapping and observation of (Tempel’s) nucleus to see new areas of the nucleus we hadn’t seen before, so it will help complete the mapping of the nucleus of this comet. And, then if possible, we would like to be able to image a crater that was left behind” from the Deep Impact.

Comets are mostly icy chunks of rock material which are locked in an elliptical orbit around the Sun. As the comet nears the Sun, a white fuzzy atmosphere envelopes around the icy rock and forms a tail region due to solar radiation.

There are about 4,000 known comets, and Tempel 1 orbits past the Sun once every 5 1/2-years, and out to a region between Mars and Jupiter.

As Stardust races near the comet at 24,300 miles per hour, the craft’s science and navigation instruments will be activated.

The Comet and Interstellar Dust Analyzer instrument will be turned on at about 8:30 pm, and run until about 2:30 am Tuesday morning. This analyzer will study the masses of ions from the dust particles which surround the comet.

The Dust Flux Monitor will be turned on at about 11:16 pm, and will study the make up and size of dust originating from Tempel 1′s coma.

The nearly five mile long and three mile wide comet rotates once every forty-one hours.

The Stardust mission has had a very storied career since it’s February 1999 launch aboard a Delta II rocket from Cape Canaveral.

In 2002, the craft flew by the Annefrank asteroid making observations and taking thousands of images. Over a year later, the craft flew by it’s main target, comet Wild 2.

A section of Stardust known as the sample material capsule collected dust and particles from Wild 2.

In January 2006, the sample material capsule returned to earth, landing in Utah.

The mission was then extended in late 2006 at a cost of $29 million to keep the spacecraft alive through September of this year.

Total Lunar Eclipse from Nicaragua

One of the most wonderful astronomical events available without the need
of any particular artificial optical instrument, and shared almost
instantaneously in a whole hemisphere is without doubts a Lunar Eclipse.

And the Eclipse from December 21st, 2010 was no exception to the
previous statement, with so many good astro-friend in may Countries that
were as expectant as I was for this event.

This particular eclipse coincided with the Winter Solstice for the
Northern Hemisphere and happened to be one of the most “darkest”
(meaning that: one where the shadow of our planet fell almost perfectly
over the lunar disc) in the recent times.

With so many expectation and nerves, a small group from ANASA
gathered at the fields of the Pierre & Marie Curie elementary
school, in the outskirts of Managua; battling against mosquitoes and the
late hour of the event. For Nicaragua, the Penumbral part of the
eclipse began on Dec. 20th, 23:30 hours.

Around some 40 people joined us, mostly kids; willing to observe
their first Lunar Eclipse. Weather forecast were reserved for us,
talking about heavy clouds and strong winds.

We were able to enjoy the eclipse just until a few minutes past the
initial part of Totality, where those dreaded forecasts became true:
clouds rapidly covered our sky and stayed there for a very long time,
whilst a dark-reddened Moon hovered above us, hidden from our sight.

I had the chance to peek at the Moon for a brief time, using my small
telescope, in a window among the clouds, and I was amazed how really
dark it was! I was able to hint some blue and purple tint on the less
darker areas, something I had never saw before during a total eclipse.

I was glad to spent this time with my wife and several friends from
ANASA: Ricardo Ruiz, Sergio Melendez and Nohelia Ocampo. Also it was fun
to receive updates via SMS from Adelmo Sandino and Javier Ramirez,
while a diligent Luis Arguello kept an open line by phone, reporting
several times.

Sergio was so kind to bring with him the smallest telescope I have
ever seen: it resemble pretty much to a can of potatoes chips. The
resulting end: kids love it!

I invite you to share with the us the experience, by watching the pictures already posted in my Picasa web album.

Clear skies!
