The final antenna for the project is here seen arriving to the high site at the observatory, 5000 meters above sea level. Start of Early Science Cycle 2. A groundbreaking ceremony was held on November 6, 2003 and the ALMA logo was unveiled.[8]. We find them at great cosmic distances, with most of their light stretched out to millimeter and submillimeter wavelengths by the expansion of the Universe. Arrival of the two ALMA transporters in Chile. [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. 66th and final antenna arrived and accepted. 9:25-9:50 Tom Bakx The dust-obscured early Universe as probed by ALMA. European, North American & Japanese amend agreement on the Enhanced ALMA. The transporters, which feature a driver's seat designed to accommodate an oxygen tank to aid breathing the thin high-altitude air, place the antennas precisely on the pads. Although ALMA did not observe the entire galaxy merger, the result is the best submillimeter-wavelength image ever made of the Antennae Galaxies, showing the clouds of dense cold gas from which new stars form, which cannot be seen using visible light. 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. Dec 11, 2012. This video shows the antenna being moved on the giant transporter called "Otto". ESO and NRAO worked together in technical, science, and management groups to define and organize a joint project between the two observatories with participation by Canada and Spain (the latter became a member of ESO later). Further discussions between ALMA and NAOJ led to the signing of a high-level agreement on 14 September 2004 that makes Japan an official participant in Enhanced ALMA, to be known as the Atacama Large Millimeter/submillimeter Array. ("Alma" means "soul" in Spanish and "learned" or "knowledgeable" in Arabic.) History. A drone camera flies overhead the ALMA observatory, showing the 66 telescopes that make up the array in the wilderness of Chile's Atacama desert. Costing $1.4 billion, ALMA is the world’s most expensive ground based telescope.

During Autumn 2009, the first three antennas were transported one-by-one to the Array Operations Site. The inauguration ceremony took place in Chile’s high desert at an altitude of 16,500 feet, or 5,000 meters. Testing of first prototype antenna begins at the ALMA Test Facility (ATF) site in Socorro, New Mexico. ESO/NRAO/NAOJ joint site testing with Chile. The complex was built primarily by European, U.S., Japanese, and Canadian companies and universities. [18] Both transporters were delivered to the ALMA Operations Support Facility (OSF) in Chile on 15 February 2008. Red and green show the distributions of molecular gas with different velocities mapped by 13 CO emissions. It has captured images of the most distant observations of water to date. 01:32. Video compilation showing various aspects of ALMA. or moving antennas around the site to change the array size, presents enormous challenges; as portrayed in the television documentary Monster Moves: Mountain Mission. Share Tweet. The blue region in left panel shows the ionized hydrogen gas observed with the Hubble Space Telescope. [42][43], In March 2020, ALMA was shut down due to the COVID-19 coronavirus crisis. 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. Japan constructed 16 Antennas. Three prototype antennas have undergone evaluation at the Very Large Array since 2002. Alma - the most complex ground-based telescope in existence - is officially opened during an inauguration ceremony in Chile's Atacama Desert. ALMA Telescope. 「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. [10] ALMA is the largest and most expensive ground-based astronomical project, costing between US$1.4 and 1.5 billion. Telescope History. This was the number of antennas specified for ALMA to begin its first science observations, and was therefore an important milestone for the project. ALMA (Atacama Large Millimeter/submillimeter Array) is a radio telescope inaugurated in 2013. Taiwan joins the ALMA Project through Japan. First move of an ALMA antenna to Chajnantor. A talk on the Atacama Large Millimeter/submillimeter Array (ALMA), by Leonardo Testi. Two peacock-shaped gaseous clouds were revealed in the Large Magellanic Cloud (LMC) by observations with the Atacama Large Millimeter/submillimeter Array (ALMA). The array has been fully operational since March 2013.[5][6]. Featured Videos Related A Hundred Million ... History. [28], ALMA participated in the detection of phosphine, a biomarker, in the atmosphere of Venus. Although very different approaches have been chosen by the providers, each of the antenna designs appears to be able to meet ALMA's stringent requirements. Illustrated by dramatic helicopter footage, the movie takes you on a journey to the 5000-metre-high Chajnantor Plateau, where ALMA stands, in the unique environment of the Atacama Desert of Chile. The Joint ALMA Observatory (JAO) provides the unified leadership and management of the construction, commissioning and operation of ALMA. memorandum of understanding for design & development. At that size, ALMA can pinpoint small, hidden details deep inside galaxies or within giant star forming regions, making it one of the most powerful telescopes … A view across the plains of Chajnantor with the ALMA construction site at the center. 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. The Atacama Large Millimeter/submillimeter Array (ALMA) surveyed the Hubble Ultra Deep Field, uncovering new details of the star-forming history of the Universe. 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. Costing more than a billion US dollars, it is the worlds's most expensive ground-based telescope. ALMA … 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. The first vehicle was completed and tested in July 2007. The ACA works together with the main array in order to enhance the latter's wide-field imaging capability.

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. The project began when Europe, North America and Eastern Asia each worked in isolation to propose a telescope that would receive light in millimeter and submillimeter wavelengths in large magnitudes. Go inside the U. S. insurrection with a National Geographic photographer. The ALMA radio telescope. 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. [37], In August 2013, workers at the telescope went on strike to demand better pay and working conditions. A series of resolutions and agreements led to the choice of "Atacama Large Millimeter Array", or ALMA, as the name of the new array in March 1999 and the signing of the ALMA Agreement on 25 February 2003, between the North American and European parties. 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. Array configurations from approximately 150 m to 14 km, Faster and more flexible imaging instrument than the Very Large Array, Largest and most sensitive instrument in the world at millimeter and submillimeter wavelengths, Point source detection sensitivity 20 times better than the Very Large Array, Data reduction system will be CASA (Common Astronomy Software Applications) which is a new software package based on, This page was last edited on 29 December 2020, at 02:01. Working together, the separate ALMA telescopes become one giant telescope up to 11 miles (16 km) across. [27], ALMA participated in the Event Horizon Telescope project, which produced the first direct image of a black hole, published in 2019. 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. ALMA construction and operations are led on behalf of Europe by ESO, on behalf of North America by the National Radio Astronomy Observatory (NRAO), which is managed by Associated Universities, Inc (AUI) and on behalf of East Asia by the National Astronomical Observatory of Japan (NAOJ). ALMA is being built by Europe, the United States, Canada, East Asia and the Republic of Chile. By using smaller antennas than the main ALMA array, larger fields of view can be imaged at a given frequency using ACA. The American and European partners each provided twenty-five 12-meter diameter antennas, that compose the main array. A history of telescopes Mirrors of creation. By using smaller antennas than the main ALMA array, larger fields of view can be imaged at a given frequency using ACA. The bright quasar, powered by a supermassive black hole at the core of a galaxy, is seen as it was only 670 million years after the Big Bang, and is providing valuable clues about how such huge black holes and their host galaxies formed … The work stoppage began after the observatory failed to reach an agreement with the workers' union. 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. 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. 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 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). Opening of Joint ALMA office, Santiago, Chile. May 09, 2014. In 1609 an Italian physicist and astronomer named Galileo became the first person to point a telescope skyward. The antennas forming the Atacama Compact Array, four 12-meter antennas and twelve 7-meter antennas, were produced and delivered by Japan. 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. It also delayed the cycle 8 proposal submission deadline and suspended public visits to the site.[44]. 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. Start of Early Science Cycle 1. ALMA images of two molecular clouds. 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. Here’s what it found. This is one of the first strikes to affect an astronomical observatory. ALMA is a premier telescope for studying the first stars and galaxies that emerged from the cosmic “dark ages” billions of years ago. 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]. [16] The solution chosen is to use two custom 28-wheel self-loading heavy haulers. Following mutual discussions over several years, the ALMA Project received a proposal from the National Astronomical Observatory of Japan (NAOJ) whereby Japan would provide the ACA (Atacama Compact Array) and three additional receiver bands for the large array, to form Enhanced ALMA. Moonrise above the 12 meter wide access road to the ALMA High Site. The most powerful radio telescope opens its eyes and shows us the universe as we've never seen. Galileo's ink renderings of the moon: the first telescopic observations of a celestial object. 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. ALMA has its conceptual roots in three astronomical projects — the Millimeter Array (MMA) of the United States, the Large Southern Array (LSA) of Europe, and the Large Millimeter Array (LMA) of Japan. ALMA … 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. Thirty-two 12-m antennas in the 12-m array. First antenna movement with a transporter. Red and green show the distributions of molecular gas with different velocities mapped by 13 CO emissions. Image of telescope in transit at the Site Erection Facility. On 30 September 2013 the final ALMA antenna was handed over to the ALMA Observatory. 20 July 2015: The Green Bank Telescope will be one of two radio telescopes participating in $100 million Breakthrough Listen project, the biggest scientific search ever undertaken for signs of … [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. Galileo's ink renderings of the moon: the first telescopic observations of a celestial object. 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. The guests are shown with one of the giant ALMA transporters as well as other components. [1] ALMA is expected to provide insight on star birth during the early Stelliferous era and detailed imaging of local star and planet formation. 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. [2] Costing about US$1.4 billion, it is the most expensive ground-based telescope in operation. Credit: ALMA (ESO/NAOJ/NRAO)/Fukui et al./Tokuda et al./NASA-ESA Hubble Space Telescope Astronomers know that stars are formed in collapsing clouds in space. Phase closure with three antennas at Chajnantor. The blue part in right panel shows the emissions from dust particles obtained with ALMA. PROGRAM: (20 min talk + 5 min QA) 8:55-9:00 Daisuke Iono Welcome. History. The American and European partners each provided twenty-five 12-meter diameter antennas, that compose the main array. 「私たちが住む太陽系は、どのように生まれたのだろう?」 Using the ALMA radio telescope in Chile, astronomers were able to capture the formation of a new planet, and scientists are observing it happen … 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. [35], The Atacama Compact Array, ACA, is a subset of 16 closely separated antennas that will greatly improve ALMA's ability to study celestial objects with a large angular size, such as molecular clouds and nearby galaxies. European, North American & Japanese draft agreement, with Japan providing new extensions to ALMA. Featured Videos Related A Hundred Million Stars in 3 Minutes ... History. This 16-minute video presents the history of ALMA from the origins of the project several decades ago to the recent first science results. 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. [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. The 130-ton ALMA antenna transporter "Otto" during its naming ceremony. First interferometry with two antennas at the Operations Support Facility (OSF). A Panchromatic View of Galaxy Build-up in the First 2 Gyrs of Cosmic History-----Venue: Online Date: December 15, 2020. On March 13, 2013, the ALMA Telescope in northern Chile officially went online. Share Link. 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). They are powered by twin turbocharged 500 kW Diesel engines. [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. [24][25], An image of the protoplanetary disk surrounding HL Tauri (a very young T Tauri star[26] in the constellation Taurus) was made public in 2014, showing a series of concentric bright rings separated by gaps, indicating protoplanet formation. Costing $1.4 billion, ALMA is the world’s most expensive ground based telescope. 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). Calçada (ESO), アルマ望遠鏡が観測するミリ波・サブミリ波は、地球の大気に含まれる水蒸気によって激しく吸収されてしまうため、空気が薄く乾燥した高地に建設する必要がありました。また、複数の電波望遠鏡を協働させる干渉計の技術を活用するためには、たくさんのアンテナを設置するための広い平坦な場所が必要です。野心的なアルマ望遠鏡を設置するにふさわしい「観測最適地」を求めて、天文学者は世界中の高地を調査しました。, その答えとして見出されたのが、南米チリ北部、アタカマ砂漠の標高5,000mの高原です。アタカマ砂漠は年間降水量が100mm以下で、世界でもっとも乾燥した場所のひとつといわれています。日本からアルマ望遠鏡施設までは、飛行機の乗り継ぎ時間を含めると40時間ほどかかりますが、アルマ望遠鏡設置に理想的な条件を備えた、地球上で究極の場所といえます。, アルマ望遠鏡のような巨大プロジェクトは、一国だけで開発・運用できるものではありません。世界中の国々が手を取りあい、人と技術と資金を出しあうことでアルマ望遠鏡は生まれました。, 一般的に学術研究は熾烈な国際競争の場でもありますが、同時に研究者が国々を自由に行き来したり、国際協力が当たり前のように行われたりもする平和な分野でもあります。1980年代から1990年代にかけて、日米欧のそれぞれが独自の巨大電波望遠鏡を計画していました。これらの状況は国際会議でお互いに共有されていたため、お互いの良いところを取り入れていくにつれて、計画はどれも似たものになっていきました。そして、「それぞれの計画を合体させ、1つの国や地域では実現できない理想の望遠鏡を作ってはどうか」という構想が日米欧の研究者たちのなかから生まれたのです。アルマ望遠鏡計画の誕生です。, 現在のアルマ望遠鏡の運用は、日本・台湾・韓国の東アジア、アメリカとカナダからなる北米、欧州南天天文台を構成する16か国と建設地のチリ共和国の協力で行われています。日本の国立天文台のスタッフ十数名も現地に赴任し、世界中から集まってきた研究者や技術者・事務職員と協力してアルマ望遠鏡の運用にあたっています。また日本・アメリカ・ドイツに設置されたアルマ地域支援センターでは、それぞれ東アジア・北米・欧州地域にいる天文学者がアルマ望遠鏡で研究を行うためのサポートを担当しています。, 国際協力で生まれたアルマ望遠鏡プロジェクトのなかで、日本は全体のおよそ4分の1の貢献をしています。パラボラアンテナは66台のうちの16台、電波をとらえる受信機は10種類のうち3種類を日本が開発しました。日本製の16台のアンテナで集められた信号を処理するためのスーパーコンピューターも、日本が開発したものです。アルマ望遠鏡には、日本の最先端技術が惜しみなく投入されているのです。, パラボラアンテナは、はるかかなたの天体からやってくる電波が最初に触れる人工物です。微弱な電波をもれなく集めるため、アンテナの表面はできるだけ滑らかにしておく必要があります。アルマ望遠鏡では、その誤差を人間の髪の毛の太さの約3分の1、25ミクロン以下という高い精度で実現しました。, パラボラアンテナには、観測対象の天体を高い精度で追尾できる性能が求められます。アタカマ砂漠の強い日射や昼夜の大きな温度差、強い風など、厳しい自然環境のもとでこれを実現するのは簡単なことではありませんでした。, 日本製のアンテナには、アンテナ自身の微妙なゆがみを自ら計測してリアルタイムで補正する最先端の技術をはじめ、さまざまな工夫が凝らされています。, アンテナで集められた電波をコンピューターで処理するための電気信号に変換するのが、受信機です。アルマ望遠鏡では、観測した電波を10の周波数帯(バンド)に分けて電気信号に変換するため、それぞれに最適な設計で受信機を開発しました。受信する波長が短くなるほど精度の要求も高くなります。, 日本は、超伝導技術や精密機械加工技術など、最先端技術の粋を集め、もっとも波長の短いバンド10受信機を含む3種類の受信機を開発し、全66台のアンテナに搭載される受信機を量産しました。, たくさんのアンテナからやってくる電気信号を処理するのが、「相関器」と呼ばれるスーパーコンピューターです。, 日本が開発した相関器は、日本製の16台のアンテナから届けられる膨大なデータを即座に処理する必要があります。そのデータ処理能力は、1秒間に256ギガバイト。DVD54枚(片面一層)のデータを毎秒処理することが可能です。, アルマ望遠鏡を構成する66台のアンテナのなかで、日本が開発した16台のアンテナ群と受信機、相関器からなるシステムを、「アタカマコンパクトアレイ(愛称:モリタアレイ)」と呼びます。たくさんのアンテナを連動させて、巨大な1つの望遠鏡とする「干渉計」方式の電波望遠鏡では、アンテナの間隔を広げれば広げるほど解像度が上がりますが、逆に視野は狭くなります。逆に、大きく広がった天体を広い視野で観測するためには、アンテナの間隔を小さくする必要があります。モリタアレイは、口径の小さなアンテナを狭い範囲にまとめることで、それを実現しました。, つまりアルマ望遠鏡を使う天文学者たちは、広い範囲に展開される米欧のアンテナ群と、モリタアレイの両方を組み合わせて観測することで、広がった天体のなかの細かい構造まではっきりと描き出すことができるのです。なおモリタアレイの名は、その設計に大きな貢献を残した、故・森田耕一郎 国立天文台教授にちなんでつけられたものです。アルマ望遠鏡が世界の天文学研究を今後もリードし続けるために、パワーアップのための将来開発計画も検討されています。日本の高い技術力をアルマ望遠鏡に投入することで、これからも天文学の発展に貢献していきます。, Credit:ALMA(ESO / NAOJ / NRAO)/ L.
