During an early stage of the planning of ALMA, it was decided to employ ALMA antennas designed and constructed by known companies in North America, Europe, and Japan, rather than using one single design. European/U.S. The criteria for the potential ALMA site include: (1) high atmospheric transparency at submillimeter wavelengths (2) good radio seeing to achieve sub-arcsec resolution (3) low wind velocity for a good pointing accuracy (4) flat and wide (> 3 km x 3 km) area to locate the array (5) easy accessibility to the site (6) existing infrastructure, etc. May 09, 2014. ALMA began scientific observations in the second half of 2011 and the first images were released to … It is also one of our most important scientific inventions for exploring our galaxies. This close-up image reveals one such galaxy (orange), rich in carbon monoxide, showing it is primed for star formation. Thirty-four 12-m antennas in the 12-m array, nine 7-m antennas in the 7-m array, and two 12-m antennas in the TP array. [3][4] ALMA began scientific observations in the second half of 2011 and the first images were released to the press on 3 October 2011. It was this period that the scientists in the ALPINE project focused on when they used ESO's ALMA telescope to carry out the first ever large survey of distant galaxies. Share the excitement of the inauguration ceremony and contemplate the breathtaking images from ALMA itself and views of its unique environment in the Atacama Desert. The telescope as we know it today has gone through several significant milestones since it was first patented way back in 1608. This artist's rendering of the ALMA array on the Chajnantor plateau shows how, as an interferometer, ALMA acts like a single telescope with a diameter as large as the distance between its individual antennas (represented by the blue circle). ALMA: New telescope can detect hidden gases that might hold the key to star and planetary formation. Linking three antennas allows corrections of errors that can arise when only two antennas are used, thus paving the way for precise, high-resolution imaging. European, North American & Japanese amend agreement on the Enhanced ALMA. Telescope History. By using smaller antennas than the main ALMA array, larger fields of view can be imaged at a given frequency using ACA. In 2013, the Atacama Compact Array was named the Morita Array after Professor Koh-ichiro Morita, a member of the Japanese ALMA team and designer of the ACA, who died on 7 May 2012 in Santiago. In 1609 an Italian physicist and astronomer named Galileo became the first person to point a telescope skyward. Costing $1.4 billion, ALMA is the world’s most expensive ground based telescope. ALMA images of two molecular clouds. The guests are shown with one of the giant ALMA transporters as well as other components. The ALMA radio telescope. 8 Cool Facts About the ALMA Telescope by Clara Moskowitz, SPACE.com Assistant Managing Editor ESO Photo Ambassador Babak Tafreshi snapped this remarkable image of the antennas of the Atacama Large Millimeter/submillimeter Array (ALMA), set against the splendour of the Milky Way. PROGRAM: (20 min talk + 5 min QA) 8:55-9:00 Daisuke Iono Welcome. But before ALMA could join the Event Horizon Telescope network, it first had to transform into a different kind of instrument known as a phased array. History. 「生命の材料は、地球以外の場所にも存在しているのだろうか？」, 人類が長年抱いてきたこんな疑問に挑む最前線が、アルマ望遠鏡です。南米チリの標高5,000mの高地に建設され、2011年に科学観測を開始したこの巨大望遠鏡。これを使えば、星や惑星の材料となる塵やガス、生命の材料になるかもしれない物質が放つかすかな電波を、「視力6000」に相当する圧倒的な性能でとらえることができます。惑星誕生のメカニズムや地球外生命の可能性を明らかにし、私たちのルーツを宇宙にたどること。これが、日本を含む22の国と地域が協力して運用するアルマ望遠鏡の使命です。ここでは、アルマ望遠鏡が挑む壮大な宇宙の謎と、その解明を目指す取り組みについて紹介します。, アルマ望遠鏡は、130億光年以上も遠くにある天体が放った電波をとらえ、撮影することに成功しています。130億光年離れた天体が放った光や電波は、130億年の時間をかけて地球に届くので、私たちが観測したのは、その天体の130億年前の姿なのです。宇宙で「遠くを見ること」は「昔を見ること」と同じです。先のアルマ望遠鏡の観測からは、130億年以上前の天体付近にも、すでに酸素や塵が多く存在していたことがわかりました。, 宇宙は、いまから138億年前にビッグバンで誕生したと考えられています。では、最初の銀河はいつごろどんな大きさで生まれ、進化したのでしょうか？　そして私たちの太陽系がある天の川銀河はどのように生まれたのでしょうか？宇宙の進化に大きな影響を与えたと考えられる、爆発的星形成銀河（120億年前に発生したとされる、天の川銀河の数百倍の勢いで恒星を生みだす銀河）といった謎に満ちた天体にも、アルマ望遠鏡は迫りつつあります。視力6000に相当する圧倒的な性能を駆使して、銀河の誕生と進化の謎を明らかにし、歴史を紐解いていくことも、アルマ望遠鏡の大きな目標なのです。, 宇宙の歴史の模式図。138億年前のビッグバンで始まった宇宙が膨張を続け、その中で星や銀河が生まれ、進化してきた様子を表現しています。, Credit：B.Saxton（NRAO / AUI / NSF）; ALMA （ESO / NAOJ / NRAO）; NASA / ESA Hubble, 夜空に輝く星たちのほとんどは「恒星」といって、太陽と同じように自らエネルギーを作りだして発光しています。宇宙全体にはおそらく1,000億個のさらに数千億倍もの恒星があると言われています。これまで、望遠鏡で数多くの恒星の研究が行われてきました。そして近年、天文学の進歩によって、私たちが住む太陽系と同じように、夜空に輝く恒星のまわりにも数多くの惑星が存在していることが明らかになってきました。, では、それらの惑星が誕生する様子はどんなものだったのでしょうか？「第2の地球」と呼べるような惑星は、どんな場所に、どんなプロセスでできるのでしょうか？アルマ望遠鏡は、惑星の材料になる小さな塵（ちり）やガスを観測することができます。塵やガスが集まっていく様子を詳しく観測することで、惑星が作られていく姿を描き出すことができるのです。アルマ望遠鏡の活躍により、天文学者たちは、惑星誕生の現場をこれまでになく鮮明に写し出すことに成功しています。アルマ望遠鏡は、惑星誕生のシナリオを構築し、惑星の多様性の起源を明らかにするという究極の目標に向かって、今日も観測を続けています。, Credit: S. Andrews（Harvard-Smithsonian CfA）, ALMA（ESO / NAOJ / NRAO）, Credit: ALMA (ESO/NAOJ/NRAO)/L. The ALMA image provided astronomers a major breakthrough in understanding a nearby planetary system and provided valuable clues about how such systems form and evolve. Calçada (ESO) & NASA/JPL-Caltech/WISE Team, 地球の生命のルーツは、いったいどこにあるのでしょうか？　生命の材料となる物質は、地球にしか存在しないのでしょうか？それとも、宇宙のいろんな場所にありうるのでしょうか？, アルマ望遠鏡は宇宙空間に漂う塵やガス、ガスのなかに含まれるアミノ酸などの有機物をとらえることもできます。それは、地球以外に生命が誕生する可能性を調べることにつながります。私たちの体はタンパク質でできていて、タンパク質はアミノ酸でできています。アミノ酸が宇宙に存在することがわかれば、地球以外で生命が発生する可能性があるかもしれません。アルマ望遠鏡は、アミノ酸をはじめとするさまざまな有機分子が放つ特有の電波をとらえることを目指しています。, アルマ望遠鏡の活躍により、惑星誕生の現場で複雑な有機分子がすでに何種類も発見されています。アミノ酸があれば必ず生命が生まれるわけではありませんが、少なくともその前提がどれくらいの確率で整っているのか、アルマ望遠鏡による観測で明らかになる日も遠くないでしょう。, ここまでに挙げたさまざまな宇宙の謎に迫るために重要なのが、宇宙からやってくる電波を望遠鏡でとらえることです。夜空に輝く恒星たちは、表面の温度が数千度～数万度という高温のため、私たちの目にも見える光（可視光）を発しています。すばる望遠鏡のような光学望遠鏡は、その恒星が放つ光をとらえることができます。しかし、惑星の材料となる塵やガス、ガスに含まれるアミノ酸はマイナス260℃程度と、とても低温なため、光を放つことができません。アルマ望遠鏡はこの塵やガスやアミノ酸が放つ電波をキャッチすることで、銀河や星、惑星の材料、そして生命の材料となる物質の分布や性質を明らかにしようとしています。, 下の画像は、2つの銀河が衝突しつつある「触角銀河」の画像です。アルマ望遠鏡が電波で観測した画像と、光学望遠鏡が可視光で観測した画像を重ねることで、可視光では見えなかった低温のガスの分布を見ることができます。アルマ望遠鏡が観測できるのは、「ミリ波・サブミリ波」と呼ばれる電波です。ミリ波・サブミリ波を観測する望遠鏡はほかにもいくつかありますが、非常に高い感度と解像度（視力）をあわせもつアルマ望遠鏡は、大きく抜きんでた存在であり、これまで見ることができなかった宇宙の姿を詳しく描き出すことができます。, 電波と可視光で観測した触角銀河。電波では、可視光では見ることのできないガスや塵の分布を知ることができます。, Credit：ALMA（ESO / NAOJ / NRAO）, ESO, NASA / ESA Hubble Space Telescope, 世界最大級を誇るすばる望遠鏡の口径が8.2mもあるとおり、望遠鏡は、その口径が大きければ大きいほど弱い光や電波をとらえることができ、また解像度（視力）も向上します。このため、天文学者はより口径の大きな望遠鏡を作りだすことに力を注いできました。しかし、ある程度以上大きな望遠鏡は、技術的な限界から作ることが困難です。この限界を突破するためのアイデアが、「小さな望遠鏡を広い場所にたくさん並べ、それらを連動させて1つの巨大な望遠鏡として機能させる」というものです。この仕組みは「干渉計」と呼ばれ、アルマ望遠鏡もその技術を使っています。アルマ望遠鏡では、口径12mのパラボラアンテナ54台と、口径7mのパラボラアンテナ12台、合計66台を結合させることで、1つの巨大な電波望遠鏡を作りだします。, アルマ望遠鏡の66台のアンテナは最大で直径16kmの範囲内に設置することができます。これは、東京の山手線の直径距離（田端〜品川間）に匹敵する大きさです。このときのアルマ望遠鏡の口径は実質16kmとなり、解像度は人間の視力に例えると「視力6000」、大阪に落ちている1円玉の大きさが東京から見分けられる能力に相当します。すばる望遠鏡やハッブル宇宙望遠鏡の視力と比べても10倍、これまでの電波望遠鏡と比べると数十倍から100倍高い性能になります。また、アンテナの位置を移動させることで、カメラのズームレンズのような働きを持たせることができます。広い視野で観測を行いたいときはアンテナを狭い範囲に集め、反対に高い解像度を得たいときにはアンテナを広い範囲に展開します。, Credit: ALMA (ESO/NAOJ/NRAO)/L. That's a huge, light-gathering eyeball! ALMA can produce as many as 1,291 baselines, some up to 16 kilometers long. ALMA Telescope. ALMA images of two molecular clouds. ALMA is a premier telescope for studying the first stars and galaxies that emerged from the cosmic “dark ages” billions of years ago. On 28 July 2011, the first European antenna for ALMA arrived at the Chajnantor plateau, 5,000 meters above sea level, to join 15 antennas already in place from the other international partners. The American and European partners each provided twenty-five 12-meter diameter antennas, that compose the main array. The participating East Asian countries are contributing 16 antennas (four 12-meter diameter and twelve 7-meter diameter antennas) in the form of the Atacama Compact Array (ACA), which is part of the enhanced ALMA. During Autumn 2009, the first three antennas were transported one-by-one to the Array Operations Site. The American and European partners each provided twenty-five 12-meter diameter antennas, that compose the main array. 66th and final antenna arrived and accepted. [23] These early images give a first glimpse of the potential of the new array that will produce much better quality images in the future as the scale of the array continues to increase. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), along with other telescopes, have discovered the most distant quasar yet found. [31], The Atacama Large Millimeter/submillimeter Array (ALMA), an international astronomy facility, is a partnership of Europe, North America and East Asia in cooperation with the Republic of Chile. Call for shared-risk Early Science proposals. Share Link. [10] ALMA is the largest and most expensive ground-based astronomical project, costing between US$1.4 and 1.5 billion. Using the ALMA radio telescope in Chile, astronomers were able to capture the formation of a new planet, and scientists are observing it happen … By using smaller antennas than the main ALMA array, larger fields of view can be imaged at a given frequency using ACA. ESOcast 51: Video report about the ALMA correlator. This location was chosen for its high elevation and low humidity, factors which are crucial to reduce noise and decrease signal attenuation due to Earth's atmosphere. 66 radio telescopes in the Atacama Desert of northern Chile, Location of Atacama Large Millimeter Array, The first two ALMA antennas linked together as an, Three ALMA antennas linked together as an interferometer for the first time, ALMA prototype-antennas at the ALMA test facility, July 2008 NRAO ALMA newsletter article by Dr. Al Wootten, National Institutes of Natural Sciences, Japan, Institut de Radio Astronomie Millimétrique, National Astronomical Observatory of Japan, After a Tough Year, ALMA's Star Begins to Rise at Last, removing excessive or indiscriminate images, Learn how and when to remove this template message, Atacama Submillimeter Telescope Experiment, "Alma telescope peers into space from Chile's mountains", "ALMA Inauguration Heralds New Era of Discovery", "At the End of the Earth, Seeking Clues to the Universe", "Alma telescope: Ribbon cut on astronomical giant", "ALMA - Atacama Large Millimeter/submillimeter Array", "Ground breaking ceremony for the Atacama Large Millimeter Array (ALMA)", "National Radio Astronomy Observatory - Legacy Content - ALMA (CV)", Chile's ALMA probes for origins of universe, "General Dynamics Receives $169 Million to Build 12-Meter Antennas for Advanced Radio Telescope", https://www.almaobservatory.org/en/announcement/result-of-the-initial-testing-of-the-japanese-aca-12-m-antenna-to-be-delivered-to-alma-2/, https://www.almaobservatory.org/en/press-release/alma-observatory-equipped-with-its-first-antenna/, "Monster Moves, Season 5, Episode 6: Mountain Mission", "European ALMA antenna brings total on Chajnantor to 16", "Birth of Planets Revealed in Astonishing Detail in ALMA's 'Best Image Ever' - NRAO: Revealing the Hidden Universe", "RELEASE 14-038 - NASA's 3-D Study of Comets Reveals Chemical Factory at Work", "Event Horizon Telescope Captures First Image of Black Hole | Astronomy | Sci-News.com", "Phosphine gas in the cloud decks of Venus", "Scientists find gas linked to life in atmosphere of Venus", "First Light for Band 5 at ALMA - New receivers improve ALMA's ability to search for water in the Universe", Creative Commons Attribution 4.0 International License, ALMA Observatory: ALMA Selects New Director, "New 2012 ALMA Video Compilation Released", "ALMA Compact Array Completed and Named After Japanese Astronomer", "Workers at Earth's largest radio telescope in Chile strike over pay, working conditions", "Workers strike at world's largest radio telescope", "ALMA resumes operations after end of workers' strike", "COVID-19 (coronavirus) Measures at ALMA", "ALMA Residencia Handed Over - New accommodation for staff and visitors at ALMA site in Chile", How the Huge ALMA Radio Telescope Works (Infographic), An optical system design for the Atacama Large Millimeter Array, Australian Square Kilometre Array Pathfinder, Canadian Hydrogen Intensity Mapping Experiment, Combined Array for Research in Millimeter-wave Astronomy, Multi-Element Radio Linked Interferometer Network, Special Astrophysical Observatory of the Russian Academy of Science, Space Telescope European Coordinating Facility, https://en.wikipedia.org/w/index.php?title=Atacama_Large_Millimeter_Array&oldid=996886963, Articles with infoboxes completely from Wikidata, Articles containing potentially dated statements from 2014, All articles containing potentially dated statements, Creative Commons Attribution-ShareAlike License, Atacama Large Millimeter and Submillimeter Array.

Placing the antennas closer together enables the imaging of sources of larger angular extent. Red and green show the distributions of molecular gas with different velocities mapped by 13 CO emissions. Discover Atacama Large Millimeter Array (ALMA) in Chile: One of the world's most advanced radio observatories sprawls across the Atacama Desert. ALMA is inaugurated after nearly three decades of planning, engineering and construction. As no known non-biological source of phosphine on Venus could produce phosphine in the concentrations detected, this indicated the presence of biological organisms in the atmosphere of Venus. Galileo's ink renderings of the moon: the first telescopic observations of a celestial object. On 30 September 2013 the final ALMA antenna was handed over to the ALMA Observatory. A merger between two galaxies led to something unique, as the news brought by Daily Mail reveals. ALMA is being built by Europe, the United States, Canada, East Asia and the Republic of Chile. The blue region in left panel shows the ionized hydrogen gas observed with the Hubble Space Telescope. Taiwan joins the ALMA Project through Japan. This 16-minute video presents the history of ALMA from the origins of the project several decades ago to the recent first science results. ALMA consists of 66 parabolic dishes, 54 of which are 12 metres (39 feet) in diameter and 12 of which are 7 metres (23 feet) in diameter. A Panchromatic View of Galaxy Build-up in the First 2 Gyrs of Cosmic History-----Venue: Online Date: December 15, 2020. [16] The solution chosen is to use two custom 28-wheel self-loading heavy haulers. Share Link. On 7 July 2008, an ALMA transporter moved an antenna for the first time, from inside the antenna assembly building (Site Erection Facility) to a pad outside the building for testing (holographic surface measurements).[19]. The initial ALMA array is composed of 66 high-precision antennas, and operates at wavelengths of 3.6 to 0.32 millimeters (31 to 1000 GHz). General Dynamics C4 Systems and its SATCOM Technologies division was contracted by Associated Universities, Inc. to provide twenty-five of the 12 m antennas,[12] while European manufacturer Thales Alenia Space provided the other twenty-five principal antennas[13] (in the largest-ever European industrial contract in ground-based astronomy). The 12-meter-diameter dish was manufactured by the European AEM Consortium and also marks the successful delivery of a total of 25 European antennas — the largest ESO contract so far. [42][43], In March 2020, ALMA was shut down due to the COVID-19 coronavirus crisis. The vehicles were made by Scheuerle Fahrzeugfabrik [de][17] in Germany and are 10 m wide, 20 m long and 6 m high, weighing 130 tonnes. ALMA was initially a 50-50 collaboration between the National Radio Astronomy Observatory and European Southern Observatory (ESO) and later extended with the help of the other Japanese, Taiwanese, and Chilean partners. However, two decades prior to this, the global scientific community had already identified the need for a radiotelescope with the characteristics of ALMA. In 1609 an Italian physicist and astronomer named Galileo became the first person to point a telescope skyward. 9:00-9:25 Tomoko Suzuki Gas contents in star-forming galaxies around Cosmic High Noon. A history of telescopes Mirrors of creation. Sixteen 12-m antennas in the 12-m array. A groundbreaking ceremony was held on November 6, 2003 and the ALMA logo was unveiled.[8]. History. The Atacama Large Millimeter/submillimeter Array (ALMA) is a telescope array in Chile that includes 66 receivers. This was the number of antennas specified for ALMA to begin its first science observations, and was therefore an important milestone for the project. Once completed there will be 66 antennas trained at the sky, working in tandem with one another to observe the cosmos, the largest and most expensive ground-based telescope in history. The array has been constructed on the 5,000 m (16,000 ft) elevation Chajnantor plateau - near the Llano de Chajnantor Observatory and the Atacama Pathfinder Experiment. Transporting the 115 tonne antennas from the Operations Support Facility at 2900 m altitude to the site at 5000 m, Three prototype antennas have undergone evaluation at the Very Large Array since 2002. The 130-ton ALMA antenna transporter "Otto" during its naming ceremony. Activates for operating the ARC have also divided into the three main regions involved (Europe, North America and East Asia). 9:25-9:50 Tom Bakx The dust-obscured early Universe as probed by ALMA. The ALMA radio telescope array captures a ring of fire – the light from a remote, well-formed galaxy more than 12 billion light years away that was gravitationally magnified as it was bent around an intervening galaxy. The array has much higher sensitivity and higher resolution than earlier submillimeter telescopes such as the single-dish James Clerk Maxwell Telescope or existing interferometer networks such as the Submillimeter Array or the Institut de Radio Astronomie Millimétrique (IRAM) Plateau de Bure facility. Go inside the U. S. insurrection with a National Geographic photographer. ALMA, currently the largest telescope array in the world, just took a look at the Hubble Space Telescope’s deepest-ever image, the Hubble Ultra Deep Field. At the end of 2009, a team of ALMA astronomers and engineers successfully linked three antennas at the 5,000-metre (16,000 ft) elevation observing site thus finishing the first stage of assembly and integration of the fledgling array. ESO/NRAO/NAOJ joint site testing with Chile. The ALMA regional centre (ARC) has been designed as an interface between user communities of the major contributors of the ALMA project and the JAO. (in HD). [29][30] However, this theory has since been overturned, and there has been a new study indicating that there is no phosphine in the atmosphere of Venus. On 11 August 2014, astronomers released studies, using the Atacama Large Millimeter/submillimeter Array (ALMA) for the first time, that detailed the distribution of HCN, HNC, H2CO, and dust inside the comae of comets C/2012 F6 (Lemmon) and C/2012 S1 (ISON). They are powered by twin turbocharged 500 kW Diesel engines. The first step toward the creation of what would become ALMA came in 1997, when the National Radio Astronomy Observatory (NRAO) and the European Southern Observatory (ESO) agreed to pursue a common project that merged the MMA and LSA. [7] The array has much higher sensitivity and higher resolution than earlier submillimeter telescopes such as the single-dish James Clerk Maxwell Telescope or existing interferometer networks such as the Submillimeter Array or the Institut de Radio Astronomie Millimétrique (IRAM) Plateau de Bure facility. The blue part in right panel shows the emissions from dust particles obtained with ALMA. European, North American & Japanese draft agreement, with Japan providing new extensions to ALMA. Galileo's ink renderings of the moon: the first telescopic observations of a celestial object. Start of Early Science Cycle 1. A talk on the Atacama Large Millimeter/submillimeter Array (ALMA), by Leonardo Testi. As of 2014[update], most theories did not expect planetary formation in such a young (100,000-1,000,000-year-old) system, so the new data spurred renewed theories of protoplanetary development. The target of the observation was a pair of colliding galaxies with dramatically distorted shapes, known as the Antennae Galaxies. The components designed and manufactured across Europe were transported by specialist aerospace and astrospace logistics company Route To Space Alliance,[9] 26 in total which were delivered to Antwerp for onward shipment to Chile. Dec 11, 2012. With this key step, commissioning of the instrument began 22 January 2010. It is composed of 66 antennas, each several metres in diameter, and works in synergy as a single giant telescope thanks to the interferometry technique. 01:32. memorandum of understanding for design & development. These long asked questions of the universe still remain a mystery, but they are about to be solved by the world’s most advanced telescope ALMA, a giant telescope that was constructed at an altitude of 5,000 meters in Chile and started its scientific observations from 2011. The blue features are galaxies imaged by Hubble. Testing of first prototype antenna begins at the ALMA Test Facility (ATF) site in Socorro, New Mexico. [37], In August 2013, workers at the telescope went on strike to demand better pay and working conditions.
