Shapley Vs. Curtis's View Of The Milky Way

That the universe extended beyond the Milky Way was already widely surmised, and this discovery didn't change much. The revolution came when Hubble compared these newfound distances with the velocities of galaxies, which can be determined by measuring their color spectra. To his surprise, he found the two to be nearly linearly correlated, leading to the conclusion that every galaxy is receding from every other galaxy, and the universe as a whole is expanding.

Curtis correctly noted that spectral lines could be seen within the spiral nebulae, and that they were generally consistent with the nebulae in the form of large assembled star clusters. These clusters supported Curtis's argument that these were in fact stellar systems, which are comparable to our Milky Way

Although the occupation had little pay, the work was tedious, and she would have no freedom to choose her topic, she had accepted. Finding another discovery, she concluded that some light from stars were absorbed by interstellar matter. The theory had not been approved by Russell and Shapley, so she did not publish her discovery, only to later have it revealed by Shapley. Throughout that time, women were expected to observe, while men constructed

At that time, the good view of the cosmos was that the universe consisted entirely of the Milky Way Galaxy. Using the Hooker Telescope at Mt. Wilson, Hubble recognized Cepheid variables, Kind of star that is used to determine the distance from the galaxy, in several spiral nebulae. Including the Andromeda Nebula and Triangulum. His observations proved that these nebulae were much too distant to be part of the Milky Way and were entire galaxies outside our own. This idea had been rejected by many people in the astronomy establishment of the time.

It was Shapley’s argument that some of the stars in the spiral nebulae had to be huge because of how bright they were and that they had to be very far away. He was correct in this argument; however Curtis was also correct that the same stars might be doing something different than what Shapley thought they were. Curtis suggested that these stars could be undergoing something new and different. Today we call the anomaly that the enormous stars were having a supernova. It had been known for a while that some stars go nova when they are dying, however these supernova were a different class by

William Herschel was an astronomer and telescope maker. It was through one of his telescopes, in March of 1781, that he discovered Uranus. Initially he believed, as other astronomers of his day, that Uranus was a comet. As he continued to observe the planet over the next four days he came to the conclusion that the planet did not have the same motion as a comet. After months of observation, he was able to chart its orbital path which would double the size of the known solar system at that time. Because of William Herschel’s discovery he opened up the heavens with his proof that there was much more to our solar system than was believed at that time. William Herschel discovered more that Uranus, he gave shape to the Milky Way, he discovered

He was different than most astronomers in his time because rather than charting the positions of stars or planets, he was collecting double stars and nebulae.

With Roger Penrose he demonstrated that Einstein's general hypothesis of relativity suggested space and time would have a start in the Huge explosion and an end in dark gaps (1970). These outcomes showed that it was important to bring together broad relativity with quantum hypothesis, the other extraordinary logical advancement of the primary portion of the twentieth century. One outcome of such a unification, to the point that he found was that dark gaps ought not be totally dark, but instead ought to emanate 'Selling' radiation and in the long run vanish and vanish (1974). Another guess is that the universe has no edge or limit in nonexistent time. This would infer that the way the universe started was totally controlled by the laws of science. Towards the finish of his life, Stephen was working with associates on a conceivable determination to the dark opening data Catch 22, where wrangle about bases on the preservation of

He also stated that galaxies are the basic building blocks of the Universe. And that is why this metamorphosis does represent one of the most significant changes. That happened in its appearance in the last 8 billion years. The professor explained that this study has shown to everyone that this kind of transformation is not exceptional. But it is in fact a part of the normal history of galaxy

The model logical upset of the Renaissance was propelled by Copernicus in the sixteenth century, and it drove in the end to the revelation of the size or size of the universe itself. Today the improvement of PC innovation and hypothesis has driven us to the edge of a much bigger and more

In an article from the website, Science Daily, researchers have discovered more evidence to support the theory of the Milky Way growing from the middle and spreading outwards over time. This evidence came from the current Gaia-ESO project that was created by the European Space Agency. After reading this article, I realized just how important this information could be. I want to know how the Milky Way was created, because then I will be able to find out more information about how my home, Earth, was created as well. I also really enjoy the topic of astronomy, so when I was looking for articles, this study caught my eye early on. The information is also incredibly recent, which means that scientists are learning new ways to see the universe

William Herschel began looking into the heavens as a hobby, he worked regularly in music and only dabbled in astrology in his free time. He was frustrated with the inability to see things as clearly as he liked and it led him to develop a better telescope than was available at the time. He worked and created a better scope and by that was able to study the stars and five planets. The planets did not interest him as much as how the stars and such are formed. His main interests were in how things were created. He studied the clusters of stars. As he was able to see better and was able to chart the things he saw, he was able to notice and take note of Uranus. In the beginning, he believed it to be a comet, and reported it to astrologers in England. Their equipment was insufficient to see the “comet”. As they continued to watch they could document that it was indeed not a comet.

The late 1920’s most galaxy he observed we are moving away from earth. Each planet are moving farther and farther apart.Even galaxy gets feather apart. Did you know that it takes the light from the sun to the earth it takes 7 minutes to travel from there to here.

The stage was set for a “Great Debate” that occurred at the National Academy of Sciences in Washington in 1920. At issue were the fuzzy “spiral nebulae” (which today we call galaxies): Were they close enough to be part of our own Milky Way, or were they sufficiently distant to be whole galaxies unto themselves? Shapley held that, given that his research had revised an increase in theinupward the size of the Milky Way, the spiral nebulae must be part of our own Galaxy. His opponent, Heber Curtis of California’s Lick Observatory, while incorrectly rejecting the great size of our Galaxy, correctly argued that the spirals were removed aggregates of stars similar to the Milky Way. Both men presented other scientific arguments supporting their views,

In the eighteenth century, Immanuel Kant proposed that there could be other galaxies and systems like
