Il décrypte ce qui se cache dans le spectre des galaxie. La cosmologie moderne est sur le point de naître.

No episódio de hoje do Horizonte de Eventos vamos contar a história do astrônomo Vesto Slipher, o Vesto foi um dos astrônomos mais importantes da história, ele trabalhou no Observatório Lowell, com um dos primeiros espectrógrafos da história, e com isso ele conseguiu medir o espectro das galáxias, e usando o Efeito Dopler ele conseguiu determinar a velocidade com a qual as galáxias estão se afastando de nós. Essas medidas juntamente com as medidas de distâncias feitas pelo Edwin Hubble no Observatório de Monte Wilson, foram responsáveis por montar um dos gráficos mais importantes da astronomia, que nos mostrou que o universo está em expansão.

The Sombrero Galaxy has taught us a lot. It provided important details about the birth, scale, and evolution of the universe. And it's a good laboratory for studying the birth of stars and the feeding habits of giant black holes. The Sombrero is about 30 million light-years away. It forms a disk that we see almost edge-on. It has a bright “bulge” of stars in the middle, and a lane of dark dust around its rim. That makes it look like a sombrero. In 1912, V.M. Slipher discovered that the galaxy is moving away from us at about 25 million miles per hour. At the time, astronomers were debating whether the entire universe was contained inside the Milky Way. Slipher's discovery indicated that the Sombrero was a separate galaxy, far beyond the Milky Way. It also suggested that the universe was expanding. The galaxy has a central black hole that's roughly 250 times the mass of the Milky Way's black hole. It appears to be “feeding” on massive amounts of gas, perhaps funneled in from outside the galaxy. Stars are being born in the galaxy's ring of dust. Studying that process can tell astronomers more about how stars are born — all from the “brim” of a galactic sombrero. The Sombrero is in Virgo. The Moon is passing through the constellation tonight, with Virgo's leading light, Spica, close to its upper right. The Sombrero is about the same distance to the lower right of Spica, and is an easy target for telescopes.  Script by Damond Benningfield Support McDonald Observatory

The Modern Creation Myth: At the start of the 20th century, mathematical physics, inspired by a series of instrumental discoveries in astrophysics, attempted to formulate an answer to the question of how the universe came to be. The resulting creation story, the big bang, was hailed as a triumph of reason and cosmic understanding. But was it really something new, or was it just a new version of the oldest myth known to humanity?

Am Lowell Observatorium in Arizona entlockt der Astronom Vesto Melvin Slipher den Himmelsobjekten immer wieder ungeahnte Informationen. Unter anderem entdeckt er, dass sich Galaxien voneinander fort bewegen. Das Fundament zur Urknalltheorie.

Zurückhaltend, vorsichtig, dabei unermüdlich sein Ziel im Auge: der Astronom Vesto M. Slipher. Für ein Semester holt das Lowell Observatorium in Arizona den Farmersohn aus Indiana - es werden 53 Jahre. Anfangs auch für Hühner und Kuh des Observatoriumsgründers zuständig, entwickelt sich Slipher zu einem der Gründerväter der modernen Kosmologie. Autor: Wolfgang Burgmer

We had the pleasure of discussing Indiana ag with Steve Howell of the Indiana Soybean Alliance and Greg Slipher of the Indiana Farm Bureau. Listen in to learn more about livestock expansion and the importance of agriculture in Indiana.  

The Discussion: You’d be forgiven for thinking we recorded this episode drunk – but we assure you, we weren’t. And you’ll have to forgive us for our crappy audio and shameless national stereotyping! But in this show, recorded from our dark sky star party in the Welsh Brecon Beacons, we discuss the event, Jeni’s talk on exoplanet research and we take a look at listeners’ emails. The News: Rounding up the space and astronomy news this month we have: A fresh look at the age and high metallicity of an observable star cluster Australia takes the plunge and announces the creation of its own space agency Research giving hints of water on planets in the TRAPPIST 1 system Hat of Woo: Paul’s festering Hat of Woo gets another airing as we take a look at the end of the world on 23rd September as planet Nibiru collides with Earth (or the beginning of The Rapture, if the world doesn’t end). Assuming you’re reading this or listening to the podcast, the world clearly didn’t end! Q&A: Listeners’ questions via email, Facebook & Twitter take us on a journey into the astronomy issues that have always plagued our understanding or stretched our credulity. This month we’re tackling a question about the consequences of discovering life on another planet to planetary exploration: “Let’s say the next Mars rover that is tweaked to find life on Mars finds some microbial life what impact would that have on the whole Mars exploration plans? I cannot imagine that one can send a crew of astronauts to Mars' surface and avoid contamination. If Mars is declared some sort of reserve shouldn't we then shelve all these plans? Clemens Unger, Melbourne Australia

The Discussion: Jeni’s back and the band is back together to discuss watching this year’s Perseid meteor shower and coverage of the Great American Eclipse The News: Rounding up the space and astronomy news this month we have: The shortlisted explorer and missions of opportunity being considered by NASA Jellyfish galaxies feeding supermassive black holes Goodbye to the Cassini Saturn explorer ‘The Other Section’: This month we keep Paul’s festering Hat of Woo out of sight and take a long look at the Voyager spacecraft on the 40th anniversary of this programme, which revealed the solar system unlike any other space mission.

The Discussion: Jeni’s bizarrely decided that a holiday is preferable to being locked in a bunker with two megalomaniacal Martians, so you’re left with an exhausted Paul and a jetlagged Ralph this month. What could go wrong? We discuss outreach at science festivals and a happy resolution to the light pollution issue in the Brecon Beacons dark sky reserve. The News: Rounding up the space and astronomy news this month we have: The new Doctor is upsetting some people (get over it!) The hunt Planet 9 takes another turn Have astronomers discovered the smallest possible star? A deep dive on the Great American Eclipse on August 21st And an update on the gravitational wave data debate Astronomy You’ve Probably Never Heard Of: This month we give Paul’s festering Hat of Woo and airing as we kick start another occasional feature looking into the science progress in areas (or astronomers) you’ve probably never heard of. This month we look at cosmology and the expanding universe from the perspective of the much-overshadowed astronomy giant, Vesto Slipher. Q&A: Listeners’ questions via email, Facebook & Twitter take us on a journey into the astronomy issues that have always plagued our understanding or stretched our credulity. This month we’re tackling a question about the effects of using a centrifuge to simulate gravity in space: “Let’s say we build a spaceship which contains a massive wheel which rotates to generate 1G. If you are standing on the inside of the outer wall of the wheel, you will be rotating at the same speed as the wheel and therefore feel the 1G. (Like you see in 2001 – A space Odyssey). So the artificial gravity is only created by the rotation and centrifugal force and not by the distortion of space time due to a massive body. Now what will happen when I jump? When I jump up, I am no longer connected to floor of the wheel. What happens to me? As I understand it, I should start to float inside the wheel, like they do in the ISS. The reason is that the centrifugal force generated by rotating wheel no longer applies to me as I am longer connected. If this is the case, then you better never run inside the wheel (running means you will have both feet of the ground between steps) and most likely need to wear Velcro shoes to ensure you stay connect to the floor of the wheel. Am I missing something as a lot of proposed interplanetary spaceships include some sort of wheel to generate artificial gravity? Your humble listener and collector of your podcast posters.

El descubrimiento de la expansión del Universo empieza en 1912, con los trabajos del astrónomo norteamericano Vesto M. Slipher. Mientras estudiaba los espectros de las galaxias observó que, excepto en las más próximas, las líneas del espectro se desplazan hacia el rojo. Esto significa que la mayoría de las galaxias se alejan de la Vía Láctea ya que, corrigiendo este efecto en los espectros de las galaxias, se demuestra que las estrellas que las integran están compuestas de elementos químicos conocidos. Este desplazamiento al rojo se debe al efecto Doppler.

On this week's episode, Alex and Brandon chat about what makes a dragon a dragon.If you live somewhere other than Texas and the winter weather has you feeling down, then grab some hot cocoa and listen Alex and Brandon talk your ears off. After one of the worst starts in the podcast's history, Brandon tries to right the sinking ship with his choice for this week's ABC's of Geekdom segment about a famous Italian video game character. No, not that one. Then they move on to some corrections, including Game of Thrones, Star Wars, Freedom Fighters: The Ray, Mortal Kombat X, Tim Blake Nelson, Witchblade, Shazam, Christopher Masterson, Smaug, and Slipher the Sky Dragon. Before the break, they also cover a bit of news, including the new subtitle for Star Wars Episode VIII, the death of John Hurt, cast by announcements for Godzilla: King of the Monsters, The Predator, and Black Panther, and some details on the upcoming X-Men tv series on FOX.After the break, they boys come back to discuss a few trailers including the teaser for the Marvel/Square Enix partnership, some gameplay of Robin in Injustice 2, and a new story for Tekken 7. Then they break Dow the nominations for this year's Razzie awards. Then for this week's feature topic, the boys discuss why video games movies are so bad and rack their brains for ways to make them better. Then they finish if the show with Brandon's first ever choice for Fan Fic Fights, this time pitting two old geezers against each other.Last but not least, Brandon decided that after getting all serious talking about American History X that we needed to lighten things up by talking about a really dumb comedy, so he has chosen Neighbors as the next movie for us to watch and discuss. We'll be talking about that in 2 weeks, so make sure to watch it and let us know what you thought!Don't forget to follow us on Twitter @AtariAlex, and @Megsikouicorean.

Presented by Prof. Karl Glazebrook on 9th September 2012.On Sep 17th 1912 Vesto M. Slipher at Lowell Observatory measured the first redshift of a galaxy and established their large velocities, this laid the groundwork for Hubble's discovery of the expansion of the Universe. One hundred years later we have measured close to 2 million galaxy redshifts (about one third of these measured in Australia) and this has been fundamental to our understanding of the structure of the Universe. In this public lecture, Professor Karl Glazebrook will tell the story of how galaxy redshift surveys have transformed our picture of cosmology and what the future might entail.

Transcript: Hubble had previously shown that many of the spiral nebulae were in fact distant systems of stars remote from the Milky Way. He then combined the distances he obtained from the Cepheid variable technique with Slipher’s redshifts and some that he measured himself to produce an amazing new result. In 1929 his study of galaxies showed that most galaxies had a redshift that was proportional to their distance from the Milky Way galaxy. This implied that galaxies were all moving away from the Milky Way, and the more distant ones were moving away the fastest. The implication of this result was a universal expansion, and this was the birth of the idea of the expanding universe.

Transcript: In 1912 Vesto Slipher working at the Lowell Observatory began a project to observe spectra of spiral nebulae. He was working under the direction of Percival Lowell who became known later for his speculation about the canals on Mars. Slipher detected rotation in the nebulae that he studied. With the Doppler Effect he was able to show that some parts of the nebulae were moving towards us and other parts moving away from us indicating rotation, but in another version of the Doppler Effect he got a surprise. The galaxies overall had a systematic red shift with respect to the Milky Way galaxy. Twenty-one out of twenty-five of the galaxies he observed were shifted in their spectra to the red by up to one thousand kilometers per second. Interpreted as a Doppler shift this meant that the galaxies were moving away from us with speeds up to a million miles an hour. At the time the result was extremely puzzling because it was ten years before Hubble would demonstrate that the spiral nebulae were actually distant stellar systems.
