Exoplanets, sure. Exo-moons too, apparently. But exo ... comets?! Yes indeed, they're a real thing, and we've known about them for ages! How do you spot something so tiny around another star, so far away? Emily has the insider knowledge, because it's something she's genuinely investigating in her job as an actual, real-life astronomer.On the web: syzygy.fmHelp us make Syzygy even better!

On Friday's show: CenterPoint Energy executives spent much of the latest Public Utility Commission meeting defending their leases of mobile generators, costing more than $800 million, that went unused during and after Hurricane Beryl. And Harris County Commissioners approved a new version of the county's income assistance program. We learn more about both developments.Also this hour: NASA has a decision to make before the end of the month about when and how to bring two astronauts home who have been aboard the ISS for two months on a journey originally intended to last just a week. We discuss the circumstances surrounding Butch Wilmore and Suni Williams' mission, the problems detected with the Starliner vehicle that took them up there, and the safety culture at NASA today.Then, we talk with astronomer Dr. David Levy, who co-discovered Shoemaker-Levy 9, a comet that hit Jupiter in 1994. He's in town to meet with a local astronomy club.And from Disney wanting a wrongful death lawsuit thrown out because the plaintiff had Disney+ to a NFL player unveiling a mayonnaise-scented cologne, we break down The Good, The Bad, and The Ugly of the week.

*Pastor Kevin Lea: RSR hosts Fred Williams & Doug McBurney welcome Pastor Kevin Lea of Calvary Church Port Orchard WA to discuss NASA's BIG mistake, and the latest news from earth and space in light of Hydroplate Theory! * Shot in the DART: Hear the details regarding the DART mission and its impact on the asteroid Dimorphos, providing further evidence for the Hydroplate Theory of the origin of asteroids. * The Best Defense: We discuss how understanding the make-up of asteroids and comets should guide research on planetary defense against impacts. *Biblical Buckshot: The Biblical descriptions of meteoroid/asteroid impacts at Sodom & in Revelation match what was observed with Shoemaker Levy 9, and what would happen if a rockpile, (and not a single rock) was pulled down by earth's gravity. *Lucy and Dinky: NASA's next probe Lucy is on its way to study 11 more asteroids, and has already shocked the world with the contact binary of Dinkenesh! (Not shocking by the HPT paradigm though)...

En este octavo programa de “Obsesión por el Cielo: Punto Focal” platicamos sobre los cometas. Históricamente estos fenómenos celestes han sido considerados como mensajeros de desastres y guerras. Ahora son estudiados con mucho interés por astrónomos ya que están compuestos del material original que se piensa formó nuestro Sistema Solar, y nos pueden dar información de este proceso de formación. En este programa comentamos sobre la historia observacional de estos objetos y su nomenclatura, repasamos las distintas estructuras que los forman, sus composiciones y sus características físicas. También comentamos sobre las distintas órbitas que exhiben los cometas, la evolución dinámica de estas, y sus posibles orígenes. Terminamos el programa hablando sobre fenómenos relacionados con los cometas como lo es la luz zodiacal y las lluvias de meteoros, y la posible contribución de estos objetos a la presencia de agua en la Tierra y la vida. Compartimos también nuestras experiencias observacionales de cometas famosos como el Shoemaker-Levy 9, Hale Bopp, Hyakutake, Halley, etc.    

El Shoemaker-Levy 9 fue un cometa que colisionó con Júpiter en 1994, proporcionando la primera observación directa de una colisión extraterrestre entre objetos del sistema solar.​

Vor 30 Jahren zog der Komet Shoemaker-Levy 9 dicht an Jupiter vorbei – zu dicht. Durch die Anziehungskraft des Riesenplaneten regelrecht durchgeknetet, zerbrach das rund vier Kilometer große Objekt aus Eis und Staub in mehr als 20 Teile.Von Dirk Lorenzenwww.deutschlandfunk.de, SternzeitDirekter Link zur Audiodatei

Astronomers have spotted the biggest comet ever! And it's heading for Earth! Except (a) it's not heading towards Earth — it's closest approach to us will be beyond Saturn's orbit — and (b) it's not technically the biggest. But it's still cool! Emily's here with loads of info about comets, big comets, things that are sort of comets, how many tails they have (hint: it's more than one), and heaps more besides.Syzygy Merch!

El pasado 13 de agosto falleció Carolyn Shoemaker, destacada astrónoma estadounidense que, entre otras cosas, co-descubrió un cometa que chocó con Júpiter en 1994. Néstor Espinoza, astrofísico del Space Telescope Science Institute de Baltimore, repasó en su columna para Razones Editoriales la vida de esta científica que comenzó su carrera a una edad avanzada y qué significó para la ciencia el descubrimiento del cometa Shoemaker–Levy 9.

Bonfire night, November 5th 2015, 9.30pm. An agent fires off an email. An author is accused of plagiarism. His new book lies ready to be pulped. In the first of a new series of Sideways, Matthew Syed asks why we're doomed to be unoriginal and why it hurts so much to be, well, not that special. In 1998, Hollywood directors Matthew Bay and Mimi Leder went head to head with suspiciously similar disaster movies - Armageddon and Deep Impact. Allegations of late-night spying flew around. But could there have just been something in the air? Matthew reveals that, four years earlier, fragments of the Shoemaker-Levy 9 Comet smashed into Jupiter and right into the American consciousness. This is the thing... As Matthew discovers, our brains are wired for unoriginality, we evolve as a collective brain, absorbing our shared cultural cues and looking for what has worked in the past. But if that's the norm, why do we feel so disappointed when our ideas seem unoriginal, when someone else beats us to it? And is there a way out of this - to rekindle our originality? With author Ian Leslie, Kristen Lopez, TV editor for Indiewire and pop culture critic, Dr Michael Muthukrishna, Associate Professor of Economic Psychology at the London School of Economics and Nick Groom, Professor of Literature in English, University of Macau.

Pour cette partie, nous allons un peu plus parler d’Histoire avec un grand H car le contexte a en réalité souvent son importance. Personne ne vit en dehors de son époque, les idées ne sont pas des choses éthérées qui vivraient au-delà du quotidien des humains.Pour te le prouver, j’ai un parfait exemple pour toi. Alors détend-toi, installe-toi confortablement je vais te raconter une histoire plein de science et de rebondissement. Johannes Kepler Celui dont je vais te conter l’histoire n’est pas n’importe qui. Son nom ne t’es peut-être pas inconnu mais il est peu probable que l’on t‘ait déjà parlé en détail de l’étendue de son talent et il est encore moins probable que l’on t’ai conté l’histoire de sa vie. Cet homme est Johannes Kepler. Au lieu de simplement te parler de ses découvertes, j’aimerais te parler un peu du parcours atypique de Johannes Kepler car il est étrangement erratique pour quelqu’un qui énoncera des lois de mouvement si régulières. Alors laisse moi te conter le récit de la vie de l’un des esprits les plus importants de l’Histoire de l’astronomie. Lors de sa naissance, en 1571, l’Europe est en proie à deux révolutions :50 ans plus tôt, un écrit était cloué à la porte d’une église, et sonna le début du protestantisme,26 ans avant, un certain Copernic avait démontré que le soleil ne tournait pas autour de la Terre, mais l’inverse, ce qui est une étape scientifique plus que notable C’est un temps agité et où les autorités religieuses sont sérieusement remises en questions. Physiquement, il est assez chétif et a une vision abîmée par la variole… Des signes qui pourraient plutôt annoncer une mort rapide qu’une destinée brillante. Alors qu’il a 6 ans, un évènement changera sa vie à jamais : une comète apparaît dans le ciel et elle est tellement brillante que toute l’Europe est subjugée. Petit rappel d’histoire, Kepler est plus ou moins Allemand, au sens qu’à l’époque il n’y a pas d’Allemagne à proprement parler, mais le Saint-Empire romain germanique, qui s’est étendu du sud du Danemark au nord de l’italie et de l’alsace à Vienne en autriche. A l’époque, la guerre de 30 ans opposant catholiques et protestants n’a pas encore éclaté et Kepler s’inscrit en 1589 dans l’université de Tübingen dans le but d’étudier la théologie et devenir un pasteur. Il rencontre alors l’homme qui changea à tout jamais son destin, (et celui de la science elle-même, indirectement) : Maestlin. Un nom qui n’est pas si connu dans l’histoire mais dont le rôle ici est essentiel. Maestlin est secrètement un disciple de Copernic. Evidemment, à l’époque il faut bien savoir tenir sa langue lorsque l’on pense que la Terre n’est pas au centre de l’Univers, sous peine de se voir torturer. En voyant la passion de Kepler pour l’astronomie, il lui prêta alors discrètement l’oeuvre de Copernic. Cela fut un choc et fascina Kepler qui y vit alors non pas l’hérésie, mais l’oeuvre divine d’une mécanique harmonieuse. Kepler est âgé alors de 23 ans et malgré sa passion pour les astres, il pense toujours devenir pasteur, mais une rencontre va une nouvelle fois changer sa vie : La ville de Graz, en Autriche, l’invite à venir enseigner les mathématiques. Emballé par l’idée de vivre de sa passion scientifique, Kepler accepte mais peu de personnes suivent ses cours et il est alors contraint d’accepter un second poste : celui de créateur de calendrier. Ce qui à l’époque tient plus de l'astrologie que de l'astronomie. Johannes Kepler, malgré ses publications astrologiques reste réaliste quand à leur portée :“Le ciel agit sur l’homme pendant sa vie , comme les ficelles qu’un paysan noue au hasard autour des courges de son champ : les nœuds ne font pas pousser la courge, mais ils en déterminent... la forme.De même pour le ciel : il ne donne pas à l’homme ses habitudes,son histoire, son bonheur, ses enfants, sa richesse ou sa femme, mais il façonne sa condition”. Toute sa vie, Kepler oscille ainsi entre religion et science, arrivant à trouver un équilibre, notamment grâce à son protestantisme, lui permettant plus de flexibilité individuelle dans la foi que le catholicisme régi par l’autorité d’un Pape. Le manque de succès dans sa carrière a tout de même un avantage particulier : il dispose de temps libre pour réfléchir. Si la terre tourne autour du Soleil, elle n’est donc attachée à rien, flottant dans l’Espace. Mais qu’est-ce qui la fait flotter ? quelle est la raison qui fait qu’elle ne dérive pas et décrit une orbite autour du soleil. Lors d’un énième cours quasi-vide en 1595, Kepler a une illumination : Si la Terre tourne autour du Soleil, c’est probablement car le Soleil applique sur elle une force ! Newton était alors loin d’être né, il faudra encore attendre près de 50 ans, donc cette force, kepler l’appela “magnétisme”. Cela peut paraître évident, et même un peu faux, mais en Europe, il fut le premier à émettre cette théorie si proche de la réalité. Mais Je te rappelle que Kepler est avant tout très religieux, il va alors commencer par calculer l’espace entre les planètes et les relier aux formes sacrées de platon et y trouver une correspondance qui lui fera penser à l’oeuvre de Dieu lui-même. Mais si cela te parait absurde, sache que cette nouvelle approche sera ce qui permettra aux scientifiques d’avancer, sous couvert de découvrir comment “Dieu l’a fait”. Et c’est ce qui déclenche la révolution scientifique qui suivra peu après. Il va plus loin et trouve une harmonie qui pourrait être transcrite en musique et compose une version de “Harmonie des sphères”.L’idée de lier musique et astronomie n’est pas de lui et se retrouve depuis Pythagore et les premiers acousmaticiens.La différence est que dans sa version, au lieu de baser sa composition sur la distance entre les planètes, il se base sur leur vitesse. L'ensemble des planètes constitue un chœur (pas forcément très harmonieux) où la basse est dévolue à Saturne et Jupiter, le ténor à Mars, l'alto à la Terre et à Vénus, le soprano à Mercure Deux ans plus tard, en 1597, il publie ses idées, ce qui attira l’attention d’un certain Tycho Brahe un astronome qui voulait déménager à Prague pour continuer ses activités et ils deviennent correspondants réguliers. Cela va sauver la vie de Kepler. En 1599, la tension entre protestant et catholique est à son comble dans la ville de graz où Kepler est toujours installé.Il ne peut retourner dans son ancienne université où ses affinités avec les théories coperniciennes sont rejetées et c’est Brahe qui lui sauve la vie en lui proposant de venir à Prague pour l’assister dans ses travaux. Il se retrouve donc dans la cour du roi Rudolf II, un roi particulier, dans son affection pour le scientifique autant que l’occulte.Il était entouré d’alchimistes, d’astrologues comme de mathématiciens et d’astronomes, l’un des astronomes étant Brahe, sous le titre de “mathématicien impérial”. Sa mission était d’observer le ciel nocturne et de créer un relevé précis des cieux. Des relevés existaient avant lui, mais ils étaient imprécis ou incomplets.Le but était de créer une carte si précise que l’on pourrait alors prédire les positions des astres avec la plus grande des précisions. Mais en 1601, Brahe décède et le relai est passé à son second, Kepler, arrivé moins de deux ans plus tôt. La tâche qui lui est transmise est immense mais il hérite des travaux que son prédécesseur gardait jalousement : les observations astronomiques les plus précises de tous les temps. C’est ces dernières qui vont permettre les plus grandes découvertes faites par Kepler. Et si l’astronomie est son oeuvre la plus connue, Kepler est aussi connu pour avoir fait avancer bien d’autres champs de la physique, par simple intérêt fugace dans la matière. En 1604, par exemple, alors qu’il tente d’améliorer la façon d’observer une éclipse, il plonge alors si loin dans l’étude de l’optique qu’il va en profiter pour avancer la compréhension de l’oeil humain, découvrant que l’image au fond de notre rétine est inversée et corrigée par le cerveau.De ces études, il en profite aussi pour améliorer les verres optiques, notamment les lunettes, dont il a grandement besoin avec sa myopie dont il souffre depuis l’enfance.Pas la lunette astronomique évidemment puisqu’elle n’est pas encore inventée à l’époque. La même année, il observe et enregistre une supernova dans le ciel, sous la forme d’une étoile nouvelle. Il a même publié un ouvrage nommé “Le songe” ou “L’astronomie lunaire” qui est un des premiers ouvrages de science fiction.Un roman basé donc sur des faits scientifiques qui raconte une aventure sur la Lune entreprise par des humains aidés de démons, dans laquelle Kepler note les difficultés à prévoir une fois sur place : l’absence d’air bien entendu, mais aussi la lumière du soleil, non filtrée par une quelconque atmosphère.Il en profite aussi pour décrire avec poésie la vue de la Terre qu’auraient les aventuriers Les années d’observation attentive vont lui permettre de prouver scientifiquement les théories coperniciennes et le système héliocentrique. En 1609, il publie “Astronomie nouvelle”, qui non seulement explique le trajet de Mars dans le ciel nocture terrestre, mais il calcule et représente celui de la Terre vu depuis la planète rouge. Cette réflexion et ces calculs lui permettent de constater que les trajectoires des planètes ne sont pas circulaires et elliptiques, ovales, où l’un des centre est le soleil. C’est la première loi de Kepler Il démontre par le calcul la vitesse des astres, selon leur position sur cette ellipse, indiquant que lorsqu’un corps est sur la partie de son orbite la plus proche de l’astre autour duquel il gravite, sa vitesse est plus grande que lorsqu’il en est éloigné.Il arrive à trouver la relation qui régit la distance parcourue tout au long de la révolution.C’est la seconde loi de Kepler.Il n’est pas arrivé encore à permettre le calcul des paramètres de l’orbite elle-même, en revanche. Un fait intéressant, car très rare à l’époque : non content de publier ses théories, il publie aussi ses données brutes. De nos jours c’est une norme lors de publications scientifiques, mais à l’époque, c’est une forme de défiance envers les critiques potentielles, leur donnant la possibilité de le contredire… si toutefois c’était possible. En 1610, Galilée observe Jupiter avec la première lunette astronomique et sa découverte crée tellement l’émoi que beaucoup à l’époque pensent qu’il s’agit d’une erreur, voir d’une illusion d’optique. Cela inspira un nouvel ouvrage à Kepler qui non seulement démontre que les observations de galilée ne pouvaient être une illusion optique mais il en profita au passage pour décrire comment améliorer les télescopes pour les rendre plus efficaces. Mais les tensions religieuses au sein de l’Europe finiront par le rattraper et en 1612, le voilà encore contraint de quitter Prague pour Linz qui lui propose un poste de mathématicien en échange duquel il doit achever les tables d'observations du ciel. Il a encore une fois de la chance car à peine 5 ans plus tard, en 1617, les protestants seront massacrés à Prague et en 1618, ces derniers se rebellent et la guerre de 30 ans débute entre ces deux religions, apportant dans toute l’europe, son lot de morts, de pandémies et par la peur qu’elles occasionne, son lot de procès pour sorcelleries. en 1619, Kepler, que la guerre a fini par rattrapper, protestant au milieu de catholiques, reste officiellement protégé mais est harcelé quotidiennement. Malgré ce quotidien tourmenté, il parvient à créer la loi permettant de calculer l’orbite de tout astre d’un système planétaire en découvrant la relation entre ses dimensions et la vitesse de l’astre qui la parcourt. Pendant une année, il doit s’occuper de la défense de sa mère, accusée de sorcellerie, procès lors duquel ses capacités de démonstrations lui permettront se la sauver. Mais ce procès le cribla de dettes et il perdit sa maison et quitta Linz en 1626. Un an plus tard, il publia la table d’observation dont il avait hérité de Brahe et qu’il avait grandement complétée.Ce furent les observations les plus précises jamais vues et ses 3 lois étaient bien entendues utilisées dans cet ouvrage pour prédire des évènements futurs. Le prochain évènement serait le transit de Mercure, 4 ans plus tard, en 1631, un phénomène où, depuis la Terre, nous pouvons observer Mercure passer entre le soleil et nous. Mais non seulement il ne vécut pas jusqu’à voir son travail validé, mais la guerre de religion fera que sa tombe sera profanée.Nul ne sait ce qu’il est advenu de son corps. Bien évidemment, en 1631, ce transit a lieu, comme prédit par Kepler. Conclusion Ces travaux sont la fondation de bien des découvertes et ont inspiré bien des scientifiques. Cela permettra à Newton de créer sa théorie gravitationnelle et permettra la mesure de l’unité astronomique ( la distance terre-soleil) grâce l’observation du transit de Vénus, 8 ans après Mercure. Il est vrai que je parle et que je continuerai à beaucoup parler des hommes de sciences. Cela ne veut pas dire qu’il n’a pas existé des femmes de sciences durant l’aventure scientifique qu’a vécu l’humanité. Tu peux être ainsi amené à penser que jusqu’à récemment, elles ont souvent été reléguées à un rôle de soutien. Femme au foyer ou secrétaire, qu’elles dégageaient le chemin pour que leurs conjoints ou supérieurs puissent faire avancer les connaissances humaines. Ou alors on les imagine comme Nicole-Reine Lepaute, aidant son mari dans les calculs jusqu’à s’en abîmer la vue. Si cette image de personne en deuxième ligne n‘est pas tout à fait fausse historiquement, la réalité est un tout petit peu plus subtile, il existe bien des exceptions et ces dernières sont de plus en plus nombreuses avec l’avancé des moeurs de la société et la parité vers laquelle nous tendons doucement. Comme par exemple Caroline Herschel qui découvrit 8 comètes en tant qu'assistante de son frère, mais qui fut la première femme astronome salariée, et qui sera reconnue pour ses travaux, elle reçoit la médaille d’or pour la science prussienne et devient membre honoraire de la Royal Astronomical Society, … le tout fin 18e début 19e siècle. Mais il existe des cas plus lointains encore : comme par exemple Hypathie au 4e siècle dont les travaux ont été détruits mais dont on sait qu’ils étaient tellement avancés qu’ils lui ont valu d’être assassinée par des chrétiens fanatiques. Notons aussi au passage Émilie du Châtelet, française du 18e siècle qui fut à l’origine de la traduction en français des travaux de Newton… seule traduction jusque dans les années 2000 où une autre fut réalisée.A l’époque, maîtriser deux langues et être érudit au point de traduire un ouvrage scientifique n’est pas donné à tous et pour une femme de son époque, c’est extraordinaire. Enfin, toujours en vie de nos jours, je voudrais évoquer Carolyn Shoemaker, la personne ayant découvert le plus de comète dans toute l’histoire de l'humanité : elle a découvert 32 d’entre elles ! Et l’une de ces comètes est extrêmement connue : Shoemaker-Levy 9 ou SL9, la fameuse qui s’écrasa sur Jupiter en 1994 sous la forme d’une série de débris qui ont permis d’en savoir plus sur l'atmosphère de la géante rouge. Comme je te l’ai déjà dit le ciel est le même pour tous, et la soif de connaissance est peut-être quelque part dans notre ADN, quel que soit l’origine, le sexe ou le genre. Mais il y a une chose qui nous reliera toujours tous, c’est notre place dans l’Univers : du génie au crétin, de la vedette au groupie, du roi au mendiant, à l’échelle de l’univers nous ne sommes pas grand chose. A l’époque de Kepler, nous savons déjà que nous sommes moins importants qu’imaginé précédemment, relégué du centre de l’univers à l’un de ses astres… Mais malgré cela, nous étions toujours bien trop présomptueux.

There was a last-moment decision to make this episode an extended version of a brief program RC is presenting on Asteroid Day - June 30th. Looking back to the origin of the Taurid meteor stream and its fragmenting/disintegrations possibly timing with the climatic changes over the last 25k years, with one of its members having been the "Tunguska" object that exploded over Siberia in 1908, RC reviews the comparable explosive powers in nuclear testing and impact cratering events. The Shoemaker-Levy 9 Jovian impacts and the Tunguska airburst were supreme teaching events which Randall weaves into many learning moments for us! With a string of exclaiming headlines, he stresses the critical point that we must act on the fact that we live on a vulnerable planet...   Support Randall Carlson's efforts to discover and share pivotal paradigm-shifting information!

Randall’s back-drop sparks discussion of meteor showers and the progression of a disintegrating comet to provide the material for multiple impacts. We have learned critical lessons from Shoemaker-Levy 9, the KT boundary impact event, Tunguska, and nuclear detonations. He gets back into the work of Ted Bunch et al that compares impact markers from these events with the evidence for the YDIH. Lack of a crater is problematic to critics, but an oblique/tangential grazing of a passing object above the ice sheet is the scenario RC prefers, and includes drumlins as one of the potential effects that we now see in the landscapes.   Support Randall Carlson's efforts to discover and share pivotal paradigm-shifting information!

In questa puntata vi racconto di Shoemaker-Levy 9, la cometa che colpì Giove e lo farò in compagnia di un altra cometa che, invece, andò a colpire la Terra... per fortuna solo nella vicenda raccontata dal film Deep Impact.

Dr. Mark Boslough describes what happens when an asteroid enters Earth's atmosphere. He tell the story of how he learned of the historic 2013 Chelyabinsk impact. He also shares what it was like to see the effects of the Shoemaker-Levy 9 Jupiter impact.

Code-breaker and father of computer science, Alan Turing has been chosen to celebrate the field of science on the new £50 note. Adam Rutherford asks Chief Cashier at the Bank of England, Sarah Johns how and why he was selected and he asks Sue Black, Professor of Computer Science and Technology Evangelist at Durham University, who campaigned to save Bletchley Park, what this accolade means. In 1969, while millions watched the Apollo 11 moon landing on the television, BBC radio was providing scientific and engineering commentary throughout the day. One young scientist brought in to help interpret the lunar landscape was Lionel Wilson, at the time he had just finished his PhD on the mechanics of the Moon's surface. But after seeing evidence of ancient lava fields in the pictures beamed back to Earth, he changed the course of his career and spent the next 50 years studying volcanology on Earth and in space. 25 years ago, the planet Jupiter was peppered with over 20 cometary impacts, this had never been seen before. The comet was Shoemaker Levy 9, which had already broken into icy pieces. Its fiery death had been foretold a year earlier when calculations showed its orbit was due to cross Jupiter's. As D-day approached, July 16 1994, experts wondered whether there would be fireworks, or a fizzle, they weren't disappointed. Producer - Fiona Roberts

It’s 50 years since the moon landing and 25 years since Shoemaker - Levy 9 crashed into Jupiter. The Apollo missions returned to earth with cargos of moon rocks and the comet crash showed us what happens when celestial bodies collide. We look at the significance of both this week, and also contemplate a return to the moon. What will the next generation of moonwalking astronauts do there? One thing’s for sure, they’ll be examining moon rocks once more – though this time with a range of scientific tools which hadn’t been invented when the Apollo missions ceased.

Presented by Prof. Andreas Burkert on 29th March 2019. The Galactic Center is one of the most fascinating and extreme places in the Milky Way. Harboring a supermassive black hole with a mass of order four million solar masses, it experiences cycles of activity and star formation, separated by periods of quiescence that last of order a million years. The Milky Way’s supermassive black hole currently is inactive. However a small, diffuse gas cloud (G2) has recently been detected on an orbit almost straight into the Galactic Supermassive Black Hole. Like comet Shoemaker Levy’s 1994 collision with Jupiter, the big challenge has started for astrophysicists to predict the outcome of G2’s close encounter with the supermassive black hole. Their models will be validated directly by observations within the next decade.

Yep. Podcats. Not a typo. This week we take a journey back to 1994, just after an astronomer named Heidi Hammel — as well as the entire scientific community at large — learned that a fragmented comet named Shoemaker-Levy 9 was going to crash into Jupiter at a speed of more than 130,000 miles per hour. "We have witnessed other impacts,” Heidi tells us. “What was really special about the Jupiter one was we had warning that it was going to happen.”  This moment was huge for Heidi, who was just a young astronomer from the Massachusetts Institute of Technology at the time. She was asked to lead the team that would analyze photos of the impacts taken by the still-relatively-new Hubble Space Telescope.  Oh yeah, in this podcast episode Heidi also compares planets to cats and herself to a veterinarian so PODCATS!

Zuerst zerbrach er ihn in 21 Teile, und dann ließ Jupiter den Kometen Shoemaker-Levy 9 zwischen dem 16. und dem 22. Juli 1994 Stück für Stück in seiner Atmosphäre verschwinden. Dieser Kometeneinschlag in einen Planeten war zum ersten Mal fast live im Internet zu sehen. Autor: Florian Hildebrand

Transcript: The current model of a cometary nucleus is called the dirty iceberg model, first proposed 50 years ago by Fred Whipple. The icy nucleus is a composite with rock, and comets can break up under gravitational forces or under the pressure of expanding frozen gases. Shoemaker-Levy 9 near Jupiter was an example of a comet breaking up under the gravity force of the giant planet. The icy material in a comet nucleus is composed primarily of frozen water, methane, ammonia, and carbon dioxide. In 1986 a fleet of spacecraft got very close to comet Halley, and Giotto in particular was able to take beautiful pictures of the comet nucleus showing that it was in fact very dark and covered with dust as dark as black velvet reflecting only four percent of the light from the Sun. Different comet nuclei may be darker, caused by dust material, or brighter, caused by frozen gases.

Transcript: When we look at the Moon we are looking in a mirror. The Moon has lived for the same length of time as the Earth, 4.6 billion years, and its cratered surface reflects impacts occurring throughout its history. Most of those impacts occurred during the era of heavy bombardment within the first few hundred million years. However, a significant number of large impacts have occurred throughout cosmic time. On the Earth, however, geological activity and erosion has erased most of the evidence of craters. Of the several tens of millions of potentially impacting bodies that reach the upper Earth's atmosphere, only a few land everyday as meteorites, and most of them are very small. So on the Earth evidence of cratering is rare. In northern Arizona, the Barringer crater, in a dry desert region, is one of the best preserved craters dating back twenty-five thousand years. The impactors are traveling fast, 25 to 100 thousand miles per hour. An enormous energy is released when a meteorite is brought to zero velocity, and its kinetic energy must be turned into heat energy. But impacts do happen. In 1994 astronomers watched the comet Shoemaker-Levy break apart into pieces and slam into the atmosphere and eventually the surface of Jupiter using the Hubble Space Telescope.

Jupiter has long been an object of wonder, with its dramatic Great Red Spot, its numerous and varied satellites and the stunning collision of the comet Shoemaker Levy 9 with the Jovian atmosphere in 1994. This unit will introduce you to our solar system's largest planet and its major satellites and the history of their exploration. This study unit is just one of many that can be found on LearningSpace, part of OpenLearn, a collection of open educational resources from The Open University.

David H. Levy is one of the most successful comet discoverers in history. He has discovered 22 comets, nine of them using his own backyard telescopes. With Eugene and Carolyn Shoemaker at the Palomar Observatory in California he discovered Shoemaker-Levy 9, the comet that collided with Jupiter in 1994. That episode produced the most spectacular explosions ever witnessed in the solar system. Levy is currently involved with the Jarnac Comet Survey, which is based at the Jarnac Observatory in Vail, Arizona but which has telescopes planned for locations around the world. Levy is the author or editor of 35 books and other products. He won an Emmy in 1998 as part of the writing team for the Discovery Channel documentary, "Three Minutes to Impact." As the Science Editor for Parade Magazine from 1997 to 2006, he was able to reach more than 80 million readers, almost a quarter of the population of the United States. A contributing editor for Sky and Telescope Magazine, he writes its monthly "Star Trails" column, and his "Nightfall" feature appears in each issue of the Canadian Magazine Skynews. David Levy has given more than 1000 lectures and major interviews, and has appeared on many television programs, such as the Today show (4 times), Good Morning America (twice), the National Geographic special "Asteroids: Deadly Impact", and ABC's World News Tonight, where he and the Shoemakers were named Persons of the Week for July 22, 1994. Also, Levy has done nationally broadcast testimonials for PBS (1995-present), and for the Muscular Dystrophy Association Telethon (1998-1999). He and his wife Wendee host a weekly radio show available worldwide at www.letstalkstars.com. In 2004 he was the Senator John Rhodes Chair in Public Policy and American Institutions at Arizona State University. He has been awarded five honorary doctorates, and asteroid 3673 (Levy) was named in his honor. In 2010, David became the first person to discover comets visually, photographically, and electronically. On June 6, 2010, David was awarded a Ph. D. from the Hebrew University of Jerusalem for his dissertation for the Department of English on the topic of "The Sky in Early Modern English Literature: A Study of Allusions to Celestial Events in Elizabethan and Jacobean Writing, 1572-1610." Levy is President of the National Sharing the Sky Foundation, an organization intended to inspire new generations to develop an inquiring interest in the sciences, or in other words, to reach for the stars. Levy resides in Vail, Arizona, with his wife, Wendee. After teaching Physical Education in the Las Cruces school district for 26 years, in 1996 Wendee became the manager of Jarnac Observatory, and was promoted to Director in 2004. Wendee is an integral part of our Jarnac Comet Survey, helping to organize the program and scan the images. As Secretary-Treasurer of the National Sharing the Sky Foundation, Wendee plays a vital role in its activities. Dec, 7, 2009.
