Podcasts about extremely large telescope

Geoff Clayton is the Interim Director of Astronomy at the Maria Mitchell Association. This week Geoff talks about The Extremely Large Telescope which is being built on a mountain in Chile. It is the biggest telescope ever.

Le télescope chilien, doté d'un miroir de 39 mètres de diamètre, a pour objectif de révolutionner l'exploration, mais un complexe industriel risque d'être construit à proximité, affectant les conditions d'exploration. Dans le nord du Chili, au cœur du désert d'Atacama, le chantier du Extremely Large Telescope a débuté depuis six ans et devrait être achevé d'ici 2028. Avec ce nouveau joujou XXL, les astronomes espèrent en apprendre davantage sur les mystères les plus complexes de l'astronomie moderne, comme les trous noirs, les premières galaxies ou encore la matière noire. Mais déjà, les scientifiques s'inquiètent : un projet de méga complexe industriel pourrait voir le jour à proximité et troubler les conditions d'observations en créant de la pollution lumineuse. Naïla Derroisné, notre correspondante au Chili, a pu se rendre sur place. À la Une du Nouvelliste, en Haiti : les habitants de Petite-Rivière, en Artibonite, victimes à nouveau d'attaques des gangsLes habitants de Petite-Rivière ont été réveillés par des rafales, mercredi. L'Artibonite est encore visée par les attaques de gangs. Le bilan n'est pas encore connu, mais « il y a de nombreuses victimes civiles et parmi les forces de l'ordre », assure Frantz Duval, rédacteur en chef du Nouvelliste, interviewé en direct dans notre émission. « En ligne, des vidéos montrent les chefs de gangs qui pavoisent », dit Frantz Duval. Pour fuir les attaques, les habitants ont pris le chemin du fleuve, mais « beaucoup ont péri noyé, car il n'y avait pas assez de bateaux », indique Frantz Duval.Le journaliste haïtien, au micro d'Anne Cantener, est aussi revenu sur les conditions matérielles « très très très confortables » du Conseil présidentiel de transition.Le Nouvelliste fête ses 127 ans ce jeudi 1er mai. « Nous avons de moins en moins d'annonceurs et, entre 2024 et aujourd'hui, nous avons tout perdu, comme beaucoup d'institutions en Haïti », déplore Frantz Duval, rédacteur en chef.USA : Kamala Harris sort du silenceFace aux attaques de Donald Trump contre les immigrés, les universités, les juges, les scientifiques... beaucoup ont reproché aux démocrates de rester trop silencieux. L'ancienne candidate et ancienne vice-présidente Kamala Harris a donc pris la parole hier, lors d'un discours à San Francisco.Dans ce discours, elle a « fustigé » Donald Trump, écrit le Los Angeles Times. « Au lieu d'une administration qui travaille à faire avancer les idéaux les plus ambitieux de l'Amérique, nous assistons à un total abandon de ces idéaux », a notamment déclaré Kamala Harris. Pour la démocrate, le pays est entré dans « une crise constitutionnelle » et « les contre-pouvoirs s'effritent », rapporte le journal californien. Mais Kamala Harris garde espoir : « Ce que l'on observe aussi, ce sont des Américains qui donnent de la voix et montrent leur courage », a-t-elle clamé.Néanmoins, ce discours n'a pas convaincu la presse américaine. Un discours « mordant », mais trop conventionnel, tacle Politico. D'après le média en ligne, Kamala Harris n'a donné que « peu de nouveaux détails » sur sa vision du parti démocrate et du pays, « et encore moins d'indices sur la suite de sa carrière ». Politico croit tout de même savoir que Kamala Harris réfléchit à se présenter au poste de gouverneur de Californie l'an prochain ou à nouveau à la présidence en 2028, après sa cuisante défaite. De son côté, le Los Angeles Times souligne l'ambiance dans le public hier, un accueil « tel une rock star » et le journal de s'interroger : « Comment Kamala Harris parviendra-t-elle à convertir cette bonne volonté pour la suite ? »Le Canada, terre de refuge pour les AméricainsLes plus fragiles ou les plus directement visés par l'administration Trump décident de quitter leur pays. Le Canada voisin est donc devenu un possible refuge. Comme l'a constaté notre envoyée spéciale à Toronto, Marine de la Moissonnière.À lire aussiLe Canada, nouveau refuge pour les Américains inquiets depuis le retour de Donald Trump à la Maison BlancheUn 1er-Mai sous le signe des manifestations en Colombie et au SalvadorEn Colombie, le président de gauche Gustavo Petro avait appelé mercredi à voir « des millions » de Colombiens dans la rue pour ce 1er-Mai. Le chef d'État colombien soumet ce jour au Sénat les 12 questions de sa consultation populaire sur le travail. Exemple de question listé par le journal El Tiempo : « Êtes-vous d'accord pour que le travail le dimanche et les jours fériés soient payé double ? » Le Sénat aura ensuite un mois pour autoriser ou non ce référendum. El Tiempo anticipe donc des semaines de « mouvements et de calculs politiques » car ni l'opposition ni le gouvernement n'ont une majorité au Congrès.Au Salvador, de nombreux syndicats et partis ont appelé à manifester contre le président Bukele. « Ces deux derniers mois, la classe ouvrière a été frappée de plein fouet », dit le mouvement pour la défense de la classe ouvrière au journal El Salvador. Les manifestants protestent contre le licenciement de plus de 20 000 travailleurs du secteur public, le déplacement forcé d'habitants des zones rurales pour des projets immobiliers, les obstacles à la liberté de se syndiquer, mais aussi des salaires trop bas et, enfin, un système d'éducation et de santé publique à la traine.Bolivie : nouvel épisode du feuilleton judiciaire autour de l'ancien président Evo MoralesLe journal bolivien Los Tiempos donne donc la parole à l'avocat d'Evo Morales. D'après lui, « la justice est en train d'être rendue ». Mais, nous dit La Razon, le Tribunal suprême de justice s'indigne de cette décision qui permet, dit-il, « aux citoyens poursuivis pour pédophilie de se moquer de la justice. Nous devons protéger nos enfants ». Et le média Infobae nous apprend que le Conseil de la magistrature bolivien a lancé une enquête disciplinaire contre la juge à l'origine de cette décision. Une juge, souligne La Razon, proche d'Evo Morales. Cette juge a demandé à poursuivre l'enquête, mais dans le département de Cochabamba, le fief d'Evo Morales.La Razon rappelle qu'il y vit dans une maison barricadée, protégée par ses soutiens, pour empêcher son arrestation. Et d'après InfoBae, Evo Morales, pourtant inéligible, compte déposer une candidature présidentielle dans deux semaines à La Paz.

Just two weeks ago the world learned of an asteroid that had an almost 3 percent chance of striking earth in less than a decade. Astronomers kept looking, and a team including Olivier Hainaut at ESO's Very Large Telescope at Palanar, in Chile, have managed to narrow down the uncertainty such that we now know it will definitely not hit the earth. The secret of making such observations after most telescopes could no longer see it was down to the exceptionally dark skies there. But these may be under threat. A plan has been made to build a large power plant, including sustainable hydrogen production around 11km away from the otherwise isolated site, and astronomers around the world are rallying to call for the plant to be built further away so that its construction will not spoil the otherwise unique observation conditions. One of the signatories of a petition to that effect is Julia Siedel, also of ESO, who just last week published the first 3D atmospheric analysis of an exoplanet's climate. As she explains, future similar observations using the forthcoming, co-sited Extremely Large Telescope could be thwarted before the telescope is even finished.Back on earth, the Atlantic Meridional Overturning Current (AMOC) continues to bring warmer air and nutrients north towards the Arctic, and colder, denser water south in the global ocean overturn. But are reports of its collapse under climate change justified? A new paper this week suggests that for the next century at least it is stable though it might slow down. Jonathan Baker of the UK Met office explains how the winds in the south mean the cycle will keep turning, though it may slow down.Talking of the Arctic, Yoel Fink of MIT has dressed a couple of royal marines in wearable computer fibres for their current icy patrol in the north of Canada. Far from going commando, their underwear is measuring temperature and calorific burn to help them avoid frostbite and the dangers of the extreme environment. Yoel's paper this week describes the new device and the principle that in the future much of all of our healthcare will be provided by these sorts of wearable, stretchy, computing textiles monitoring our activities.Presenter: Roland Pease Producer: Alex Mansfield Production Coordinator: Jana Bennett-Holesworth and Josie Hardy(Image: Celestial conjunction at Paranal.

Spekulationen über außerirdisches Leben oder NHIs (Nicht Humane Intelligenzen) entwickelten sich in den vergangenen Jahren inflationär und es gab sogar Anhörungen vor dem US-Kongress zu einem Thema, das nicht lange davor noch kaum gesellschaftsfähig war. Dem gegenüber stehen Forschungsergebnisse von Dr. Helmut Lammer et al., Ende 2024 auch im renommierten Wissenschaftsjournal Astrobiology publiziert, die nahelegen, dass nach aktuellem Stand der Forschung höher entwickeltes, intelligentes Leben in der Galaxis eine ausgesprochene Rarität sei. Inwieweit aktuelle Daten des Extremely Large Telescope oder James Webb seit [%%Teil I der Sendung%%eta%%] im Jahr 2020 neue Erkenntnisse brachten, bespreche ich u.a. live mit meinem Studiogast Dr. Helmut Lammer.

Wenn wir in einer klaren Nacht in den Himmel schauen, können wir eine atemberaubende Vielzahl an funkelnden Punkten beobachten. Doch der Blick in den Sternenhimmel liefert immer nur zweidimensionale Bilder. Die dritte Dimension der Himmelsobjekte – also ihre Entfernung zur Erde – ist nicht so leicht zu bestimmen. Mit welchen Methoden Astronominnen und Astronomen den Kosmos dennoch vermessen und welche bedeutende Rolle das Bestimmen von Entfernungen im Weltall heute noch spielt, berichtet Hendrik Hildebrandt von der Universität Bochum in dieser Podcastfolge von Welt der Physik. *** Ein Beitrag von Julia Thomas, gesprochen von Ulrike Kapfer.

They episode concludes with practical advice aimed at current and aspiring church planters, emphasising the importance of perseverance and flexibility (48:23).DISCUSSED ON THIS EPISODEThe ReplacementsThe Extremely Large TelescopeThe RingerAndre the Giant documentaryMr McMahon documentaryLogan Paul's Best WWE MomentsJohn G Paton: Autobiography of the Pioneer Missionary to the New HebridesEmpire podcastSilk Roads: A New History of the World, by Peter FrankopanCONTACT USShock Absorber Email: joel@shockabsorber.com.auShock Absorber Website: shockabsorber.com.auSoul Revival Shop: soulrevival.shopCheck out what else Soul Revival is up to here

Velkommen tilbage fra sommerferie, og velkommen til den allerførste udgave af RumNyt – RumSnaks nye nyheds-format, hvor vi hveranden uge samler masser af rumnyheder fra hele Universet. Vi fordobler altså antallet af RumSnak-episoder, så der fremover kommer RumSnak hver uge – med RumNyt og “RumSnak Classic” på skift. I denne omgang RumNyt skal det blandt andet handle om kinesiske Månemissioner, vand på Mars, rumskrot og arkæologi på Den Internationale Rumstation. Vi har naturligvis også et par bonus-links, og så slutter vi episoden med en lille quiz, hvor vi skal prøve at identificere hvilke rumdata der er blevet omsat til lyd. God fornøjelse

Hosted by Dr. Jacinta Delhaize & Dr. Daniel Cunnama. The 5th of December 2022 sees the commencement of construction of the long-awaited Square Kilometre Array (SKA)! We are honoured to be joined by the SKA Observatory Council Chairperson, Dr. Catherine Cesarsky to talk about this momentous occasion. The SKA Observatory (SKAO) is a next-generation radio astronomy facility that will revolutionise our understanding of the Universe and the laws of fundamental physics. Formally known as the SKA Observatory, the SKAO is an intergovernmental organisation bringing together nations from around the world. The observatory consists of the SKAO Global Headquarters in the UK, the SKAO's two telescopes at radio-quiet sites in South Africa and Australia, and associated facilities to support the operations of the telescopes.   The SKA telescopes: Composed of respectively hundreds of dishes and thousands of antennas, the SKAO's telescopes will be the two most advanced radio telescopes on Earth. Together with other state-of-the-art research facilities, the SKAO's telescopes will explore the unknown frontiers of science and deepen our understanding of key processes, including the formation and evolution of galaxies, fundamental physics in extreme environments and the origins of life.   Dr. Cesarsky was appointed Chair of the SKA Board of Directors in 2017, and her distinguished career spans some of the biggest international astronomy projects of recent years. As Director-General of the European Southern Observatory she oversaw the Very Large Telescope, the start of construction of the Atacama Large Millimeter Array (ALMA) and launched the Extremely Large Telescope project, one of the key astronomical facilities of the coming decades along with the SKA. Among her other prestigious roles, Dr Cesarsky was President of the International Astronomical Union and High Commissioner for Atomic Energy in France. She is known for her successful research activities in high energy and in infrared astronomy and is member or foreign member of science academies over the world, including Europe (Academia Europaea), France (Académie des Sciences), United Kingdom (Royal Society), United States (NAS), Sweden (Royal Swedish Academy of Sciences).   SKAO: https://www.skao.int/   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

Adapting the pyramid wavefront sensor for pupil fragmentation of the ELT class telescopes by Nicolas Levraud et al. on Monday 19 September The next generation of Extremely Large Telescope (24 to 39m diameter) will suffer from the so-called "pupil fragmentation" problem. Due to their pupil shape complexity (segmentation, large spiders ...), some differential pistons may appear between some isolated part of the full pupil during the observations. Although classical AO system will be able to correct for turbulence effects, they will be blind to this specific telescope induced perturbations. Hence, such differential piston, a.k.a petal modes, will prevent to reach the diffraction limit of the telescope and ultimately will represent the main limitation of AO-assisted observation with an ELT. In this work we analyse the spatial structure of these petal modes and how it affects the ability of a Pyramid Wavefront sensor to sense them. Then we propose a variation around the classical Pyramid concept for increasing the WFS sensitivity to this particular modes. Nevertheless, We show that one single WFS can not accurately and simultaneously measure turbulence and petal modes. We propose a double path wavefront sensor scheme to solve this problem. We show that such a scheme,associated to a spatial filtering of residual turbulence in the second WFS path dedicated to petal mode sensing, allows to fully measure and correct for both turbulence and fragmentation effects and will eventually restore the full capability and spatial resolution of the future ELT. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.08822v1

Zahlreiche Missionen der ESA sind der umfassenden astronomischen Beobachtung des Weltalls gewidmet. Gerade hat die Mission Gaia alle Erwartungen übererfüllt und einige neue Missionen wurden gerade gestartet oder stehen schon in den Startlöchern. Doch wie läuft so eine Mission im Vorfeld ab und wie gelingt die Zusammenarbeit mit der wissenschaftlichen Community? Wir sprechen über diese Beobachtungsmissionen, das Wissenschaftsprogramm der ESA und auch die Zukunft der bodengestützen Astronomie durch das Extremely Large Telescope in Chile.

Six years ago, in episode 150, Jochen Liske of ESO told us about the Extremely Large Telescope that is currently being built in Chile. This episode is a continuation (which is why this is a kind of bonus episode labelled as 150.5) in which Thomas Pfrommer tells us about how to control the optical path of this monster telescope: the 39 meter, 798-segment main mirror, plus the four additional mirrors involved in bringing the light to a stable and sharp focus. I recorded this episode mainly to fill in some "gaps" I needed for the book chapter on telescopes.

This episode is a continuation (which is why this is a kind of bonus episode labelled as 150.5) in which Thomas Pfrommer tells us about how to control the optical path of this monster telescope: the 39 meter, 798-segment main mirror, plus the four additional mirrors involved in bringing the light to a stable and sharp focus. I recorded this episode mainly to fill in some "gaps" I needed for the book chapter on telescopes.

And from the different kinds of fruits, He made them into pairs - males and females. The night overtakes the day. These are solid proofs for people who think.   [88:17] Why do they not reflect on the camels and how they are created? [88:18] And the sky and how it is raised. [88:19] And the mountains and how they are constructed. [88:20] And the earth and how it is built. The distance to the center of the Earth is 6,371 kilometers (3,958 mi), Earth's inner core is the innermost geologic layer of the Earth. It is primarily a solid ball with a radius of about 1,220 kilometres (760 miles), which is about 20% of the Earth's radius. We have no samples of the Earth's core available for direct measurement, but from analysis of seismic waves and the magnetic field the inner core is believed to be composed of an iron–nickel alloy with some other elements. The temperature at the inner core's surface is estimated to be approximately 5700 K (5430 °C or 9806 °F), which is about the temperature at the surface of the Sun. Earth's outer core is a fluid layer about 2,400 km (1,500 mi or 40% of Earth’s radius) thick and composed of mostly liquid iron and nickel. Its outer boundary lies 2,890 km (1,800 mi) beneath Earth's surface. The transition between the inner core and outer core is located approximately 5,150 km (3,200 mi) beneath the Earth's surface. Earth’s mantle: The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles 40% of Earth’s radius) thick, and makes up a whopping 84% of Earth's total volume. Humans have drilled over 12 kilometers (7.67 miles) in the Sakhalin-I. In terms of depth below the surface, the Kola Superdeep Borehole SG-3 retains the world record at 12,262 metres (40,230 ft) in 1989 and still is the deepest artificial point on Earth. The Earth's crust is a thin shell on the outside of the Earth, accounting for less than 1% of Earth's volume. The Earth's crust ranges from 5–70 kilometres (3.1–43.5 mi) in depth. Because Earth’s crust are less dense than the mantle below, both types of crust "float" on the mantle. Mountains Moving Continental drift The Earth has 7 major plates. Each of these plates float onto of the Earth’s mantle. Each year each plate moves about an inch. When these plates collide into one another the plate that is stronger moves below and the plate that is weaker moves on top. Then over millions of years this accumulation in moving causes the formation of mountains. Mountains are waves of stone - their time horizon is much longer and move much slower [27:88] When you look at the mountains, you think that they are standing still. But they are moving, like the clouds. Such is the manufacture of GOD, who perfected everything. He is fully Cognizant of everything you do.   [79:30] He made the earth egg-shaped. 79 30 1 وَالْأَرْضَ And the earth wal-arḍa ا ر ﺽ 79 30 2 بَعْدَ after baʿda ب ع د 79 30 3 ذَٰلِكَ that dhālika ذ ل ك 79 30 4 دَحَاهَا spread it / made it egg-shaped. daḥāhā د ح و   The root for the word has predominately two meanings: the first meaning is of an egg, but specifically an ostrich egg. The word دَحَاهَا / dahaha in Arabic comes from the word for an egg, but specifically an ostrich egg. The Earth is not a perfect sphere it is an Oblate Spheroid, where the north and south pole are slightly compressed and the equator is slightly expanded. What kind of an ostrich did the Arabs at the time of the revelation of the Quran have among them? It was called the Arabian ostrich (also known as the Syrian ostrich) that sadly went extinct in the early 20th century. But luckily for us one of these eggs was discovered and preserved. It was as a gift the poet C.M. Doughty gave to archeologist T.E. Lawrence.  https://www.bbc.co.uk/sounds/play/p030vqx5 https://twitter.com/nhm_oology/status/576067708837605376 Egg yolk = core, egg white = mantle, shell = crust The second meaning of the root دَحَاهَا / dahaha means: to spread, stretch, expand, I equate this to the description of the tectonic plates of the earth. That God is giving us two pieces of information about the earth, one is its shape, the other is it’s make up. When people describe the plate tectonics of the Earth they describe it like an egg that is cracked with its shell bumping into one another. Mars Without the fragmentation of the crust of the Earth through plate tectonics the only mountains we would of had would be volcanoes. The tallest mountain in our Solar System is on Mars. It is called Mount Olympus (72,000 ft) twice as tall as Mount Everest. Early on, Mars had really active volcanoes, fed by hot, rising blobs of rock from deep inside. But Mars doesn't have tectonic plates that move over hotspots, like in Hawaii. So instead of getting a chain of volcanoes, you could keep building one huge one. And, with the lower gravity on Mars, that magma could be pushed to great heights. Plate tectonics is not necessary for the creation of mountains, but without plate tectonics many of the minerals and nutrients that are part of the crust and mantle of the Earth would never get to the surface. mountains act as elevators for minerals deep in the earth What do we gain from mountains? There are typically two words throughout the Quran that God uses in reference to mountains. الْجَبَلَ (al-jabal) = mountain رَوَاسِيَ (rawaseea) = stabilizers (78:7)   [15:19] As for the earth, we constructed it, and placed on it stabilizers (mountains), and we grew on it a perfect balance of everything. How are mountains stabilizers [78:7] And the mountains stabilizers (awtādan) ?   78 7 1 وَالْجِبَالَ And the mountains wal-jibāla ج ب ل 78 7 2 أَوْتَادًا (as) pegs / stakes (stabilizers). awtādan و ت د   [16:15] And He placed stabilizers (mountains) on earth, lest it tumbles with you, as well as rivers and roads, that you may be guided. [21:31] And we placed on earth stabilizers, lest it tumbles with them, and we placed straight roads therein, that they may be guided. [31:10] He created the heavens without pillars that you can see. He established on earth stabilizers (mountains) lest it tumbles with you, and He spread on it all kinds of creatures. We send down from the sky water to grow all kinds of beautiful plants. Rain Shadow Effect Mountains catch the moisture of rivers of water in the sky and snow and produce fresh water [77:27] We placed on it high mountains, and provided you with fresh water to drink. Beetle in the desert goes to the tops of the dunes for moisture to drink, then the birds eat the beetles for water Most mountain ranges occur along coastlines. Minerals taken from mountains and dumped into oceans and rivers for life Rain, snow and wind dissolve the limestone and send it back to the ocean, where it settles That was enough to convince them that the forces that churn the earth’s crust into jagged peaks also help our climate stay relatively stable Rivers Mountains are often called nature's water towers. ... It is no surprise then that in semi-arid and arid regions, over 70 to 90 percent of river flows come from mountains. But even in temperate areas, 30 to 60 percent of freshwater can come from highland watersheds. Carbon Cycle Climate cycle keeps temperatures stable Winds Deflects the winds Stabilize the weather   Colors [35:27] Do you not realize that GOD sends down from the sky water, whereby we produce fruits of various colors? Even the mountains have different colors; the peaks are white, or red, or some other color. And the ravens are black. Without mountains, there will be a more uniform distribution of rainfall. Aesthetically, over time, plate movements, together with other geologic processes, have created some of Nature's most magnificent scenery. Without mountains on our planet, we would lose our trees and our other plant life - moving down that chain of living things. That bedrock would be ground away by storms. The Earth would become smaller and smaller and without plants, it would lose its atmosphere. Something interesting about Mountains and specifically their tops, I don’t think any location is held more dearly to individuals globally as mountain tops. Everywhere in the world, people consider their mountains and specifically their tops as sacred, but sometimes for vastly different reasons. A perfect example of this is happening right now in Hawaii. Mauna Kea, in Hawai’i on the Big Island. Its peak is 4,207.3 m (13,803 ft) above sea level. Most of the volcano is underwater, and when measured from its underwater base, Mauna Kea is the tallest mountain in the world if you measure from its base which is ~20,000 ft below sea level, measuring over 10,000 m (33,000 ft) in height. Everest from its base is 29,029′ For generations, the Hawaiian people considered the top of their beloved mountain as sacred, and this came to a tipping point because on top of Mauna Kea is also one of the best locations in the world to observe the night sky. The brightest places in the world have the darkest skies The location is near ideal because of its dark skies from lack of light pollution, good astronomical seeing, low humidity, high elevation above most of the water vapor in the atmosphere, clean air, good weather and low latitude location. Also, Mauna Kea is one of the only places in the world where you can drive from sea level to 14,000 feet in about 2 hours. So it makes it one of the best places in the world to set up an observatory Currently, there are 13 observatories at Mauna Kea summit. Today there is an ongoing debate in Hawaii regarding the construction of the Thirty Meter Telescope (TMT) is considered an Extremely Large Telescope. It will actually be the largest telescope in the northern hemisphere, if it is built. Portal into the rest of the universe where you realize you are on this rock hurling through the cosmos  Both groups appreciate and see the sacredness in mountain tops but for two fundamentally different reasons. But both can appreciate that at these locations it instills a feeling of humility and reverence in human beings. For one we realize how insignificant we are, how vast the universe is, and how great God who created all this is.   [41:10] He placed on it stabilizers (mountains), made it productive, and He calculated its provisions in four days, to satisfy the needs of all its inhabitants. 41 10 1 وَجَعَلَ And He placed wajaʿala ج ع ل 41 10 2 فِيهَا therein fīhā ف ي 41 10 3 رَوَاسِيَ stabilizers (mountains) rawāsiya ر س و 41 10 4 مِنْ from min م ن 41 10 5 فَوْقِهَا above it fawqihā ف و ق 41 10 6 وَبَارَكَ and He blessed wabāraka ب ر ك 41 10 7 فِيهَا therein. fīhā ف ي   Humility Mountains keep people balanced between spiritual and scientific Humble and aspirational [17:37] You shall not walk proudly on earth —you cannot bore through the earth, nor can you be as tall as the mountains. [7:171] We raised the mountain above them like an umbrella, and they thought it was going to fall on them: "You shall uphold what we have given you, strongly, and remember the contents thereof, that you may be saved." Mountains humble the human instincts and reveal our insignificance We look like ants Half Dome   Mountains Day of Judgment [18:47] The day will come when we wipe out the mountains, and you will see the earth barren. We will summon them all, not leaving out a single one of them. [52:10 / 56:5 / 81:3] The mountains will be wiped out. [70:9 / 101:5] The mountains will be like fluffy wool. [73:16] The day will come when the earth and the mountains will quake, and the mountains will turn into a weightless pile. [77:10] The mountains are blown up. [78:20] The mountains will be removed, as if they were a mirage. [20:105] They ask you about the mountains. Say, "My Lord will wipe them out. [69:14] The earth and the mountains will be carried off and crushed; utterly crushed. [73:14] The day will come when the earth and the mountains will quake, and the mountains will turn into a weightless pile. No Ego: [33:72] We have offered the responsibility (freedom of choice) to the heavens and the earth, and the mountains, but they refused to bear it, and were afraid of it. But the human being accepted it; he was transgressing, ignorant. [22:18] Do you not realize that to GOD prostrates everyone in the heavens and the earth, and the sun, and the moon, and the stars, and the mountains, and the trees, and the animals, and many people? Many others among the people are committed to doom. Whomever GOD shames, none will honor him. Everything is in accordance with GOD's will.

While we're all waiting for James Webb to launch - which it will - the Extremely Large Telescope to be constructed, and LUVOIR to get approved. (Please get approved, please get approved.) We're going to need a way to pass the time. So let's have our imaginations take flight, out into the Universe, and consider some of the most incredible ideas suggested for telescopes. Unless you've been crawling through scientific journals like me, I guarantee you've never heard of any of them. But when I'm done, you're going to want to fund all of them.

Suurimmat kaukoputket maailmassa ovat tällä hetkellä peiliteleskooppeja, joiden halkaisija on noin kymmenen metriä. Nyt on jo tekeillä seuraava sukupolvi: näiden teleskooppien pääpeilin halkaisija on no 30 metriä tai enemmän. Suurin lähitulevaisuuden jättiteleskoopeista on eurooppalainen ELT, Extremely Large Telescope, eli Äärimmäisen Suuri Teleskooppi. Sen peilin läpimitta lähes 40 metriä ja kooltaan teleskooppi on suuren jalkapallostadionin kokoinen. ELT:n sijoituspaikalla Chilessä tehdään jo pohjatöitä, ja itse teleskoopin osia ollaan rakentamassa täällä Euroopassa. Jos kaikki sujuu suunnitellusti, aloittaa tämä jättiläinen havaintojen teon vuonna 2025. Tiedeykkösessä projektipäällikkö Roberto Tamai Euroopan Eteläisestä Observatoriosta kertoo enemmän ELT:stä ja sen rakentamisesta. Tähtitieteilijä Petri Väisänen puolestaan on nyt työssä Etelä-Afrikassa sijaitsevalla SALT-teleskoopilla. Kyseessä on virallisen listan mukaan maailman viidenneksi suurin kaukoputki, jonka peili on jotakuinkin kymmenmetrinen. Petrillä on siten hyvä kuva siitä, millaista tutkimusta valtavan suurilla havaintolaitteilla voi tehdä ja millaisia uusia näkökulmia ne avaavat avaruuden tutkimukseen. Hän myös selittää laajemmin mitä kaikkea tähtitieteessä on tapahtumassa. Spoiler alert: elämme jänniä aikoja ja paljon tapahtuu varsin pian. Ohjelman toimittaa Jari Mäkinen.

Das Fernrohr und dann auch bald Spiegelteleskope waren die Basis für die frühen Erkenntnisse in der Beobachtung und das Verständnis des Universums – noch lange bevor an Raumfahrt zu denken war. Doch mit den Großspiegelteleskopen seit den 1990er Jahren wurde die Beobachtungsqualität noch einmal signifikant gesteigert und lieferte noch tiefere Einblicke in die Tiefen des Alles. Neuartige Steuerungssysteme erlauben nun die Konstruktion noch viel größerer Spiegelteleskope und in wenigen Jahren wird diese neue Generation die bisher schon beeindruckende Bildqualität noch um ein vielfaches steigern. Ich spreche mit dem Astrophysiker und Professor für Beobachtende Astronomie an der Universität Hamburg Jochen Liske über Voraussetzungen für die Beobachtung des Alls, die Entwicklung der Teleskop-Technologie über die Zeit, die Herausforderungen der Astronomie als solcher, die Europäische Südsternwarte und ihre Großteleskope, künftige Projekte wie dem Extremely Large Telescope und dem kommenden Zeitalter der Multi-Messenger-Astronomie.

Paul Crowther provides an overview of the contemporary questions in astrophysics, including the nature of dark matter, the search for planets around other stars and how they will be addressed by upcoming large telescopes such as the James Webb Space Telescope and the Extremely Large Telescope, enhanced by stunning NASA, ESA, ESO images

The European Southern Observatory broke ground June 19th to build the world's largest telescope atop the Cerro Armazones mountain in Chile. Clara Moskowitz reports     

In this episode we talk with Jochen Liske from the European Southern Observatory about the E-ELT Telescope for which construction is about to start. We discuss the engineering challenges of building a 40m mirror and the associated telescope, as well as the science that is planned to be addressed with the E-ELT once it is finished. We also discuss a number of issues around optical astronomy in general that were not covered in our episode about the LBT. Joe Liske is also the host of both the HUBBLEcast and the ESOCast, two video podcasts about astronomy you may want to check out.

We catch a space dragon, chop the top off a mountain for an extremely large project, and find out how to walk on the surface of a star on this week's episode of Lagrange Point.
