EDWIN HUBBLE P erhaps more than any other person, Edwin Hubble (1884-1953) expanded our view of the universe. At the dawn of the 20th century, most astronomers thought that the Milky Way Galaxy was the universe, and it measured only a few thousand light-years across. In the 1910s, Harlow Shapley showed that the galaxy actually stretches about 100,000 light-years, and Henrietta Leavitt determined that the Large and Small Magellanic Clouds (two companion galaxies to our own, visible from the Southern Hemisphere) lay slightly outside the Milky Way’s border. But one big question that remained was the nature of the fuzzy patches of light known as nebulae. In 1923 and 1924, Hubble used the largest telescope in the world—the 100-inch Hooker Telescope at Mt. Wilson—to examine the Andromeda Nebula. The Oxford-trained lawyer-turned-astronomer detected for the first time stars similar to those in our own galaxy. By comparing how bright the stars appeared with how much light they actually gave off, he estimated the distance to the nebula as nearly a million light-years, clearly making it a huge galaxy in its own right. Hubble went on to find the distances to many other galaxies, eventually pushing the frontiers of the universe out to hundreds of millions of light-years. He then compared the distances to the speeds with which the galaxies were racing away, and deduced that the farther away the galaxy, the faster it moved. This relation, known as Hubble’s Law, was observational proof that the universe was expanding. Appropriately, the famed Hubble telescope was named in his honor.

Edwin Hubble
Edwin Powell Hubble is renowned for determining that there are other galaxies in the Universe beyond the Milky Way, and for observing that the universe is expanding at a constant rate. Hubble was a tall, elegant, athletic, man who at age 30 had an undergraduate degree in astronomy and mathematics, a legal degree as a Rhodes scholar, followed by a PhD in astronomy. He was an attorney in Kentucky (joined its bar in 1913), and had served in WWI, rising to the rank of major. He was bored with law and decided to go back to his studies in astronomy. In 1919 he began to work at Mt. Wilson Observatory in California, where he would work for the rest of his life. He was researching nebulae, fuzzy patches of light in the sky. In 1924, he announced the discovery of a Cepheid, or variable star, in the Andromeda Nebulae. Since the work of Henrietta Leavitt had made it possible to calculate the distance to Cepheids , he calculated that this Cepheid was much further away than anyone had thought and that therefore the nebulae was not a gaseous cloud inside our galaxy, like so many nebulae, but in fact, a galaxy of stars just like the Milky Way. Only much further away. Until now, people believed that the only thing existing ouside the Milky Way were the Magellanic Clouds. The Universe was much bigger than had been previously presumed. Hubble wanted to classify the galaxies according to their content, distance, shape, and brightness patterns, and in his observations he made another momentous discovery: By observing redshifts in the light wavelengths emitted by the galaxies, he saw that galaxies were moving away from each other at a rate constant to the distance between them (Hubble's Law). The further away they were, the faster they receded. This led to the calculation of the point where the expansion began, and confirmation of the big bang theory. Hubble calculated it to be about 2 billion years ago, but more recent estimates have revised that to 20 billion years ago.

Edwin Hubble was a man who changed our view of the Universe. In 1929 he showed that galaxies are moving away from us with a speed proportional to their distance. The explanation is simple, but revolutionary: the Universe is expanding. Hubble was born in Missouri in 1889. His family moved to Chicago in 1898, where at High School he was a promising, though not exceptional, pupil. He was more remarkable for his athletic ability, breaking the Illinois State high jump record. At university too he was an accomplished sportsman playing for the University of Chicago basketball team. He won a Rhodes scholarship to Oxford where he studied law. It was only some time after he returned to the US that he decided his future lay in astronomy. In the early 1920s Hubble played a key role in establishing just what galaxies are. It was known that some spiral nebulae (fuzzy clouds of light on the night sky) contained individual stars, but there was no consensus as to whether these were relatively small collections of stars within our own galaxy, the '

Hubble was offered a staff position by George Ellery Hale , the founder and director of Carnegie Institution's Mount Wilson Observatory , near Pasadena, California . He remained with Carnegie until his death in . Shortly before his death, Palomar's 200-inch Hale Telescope was completed. Hubble was the first to use it. He died of stroke on September 28 His arrival at Mount Wilson coincided roughly with the completion of the 100-inch Hooker Telescope , then the world's most powerful telescope. Hubble's observations in 1923-1924 with the Hooker Telescope established beyond doubt that the fuzzy " nebulae " seen earlier with less powerful telescopes were not part of our galaxy , as had been thought, but were galaxies themselves, outside the Milky Way .

Edwin Powell Hubble (1889-1953)
Latest Modification: June 20, 1996 Hubble attended high school in Chicago, where he excelled as a student and as an athlete. In 1906, he received a B.S. degree in mathematics and astronomy from the University of Chicago. At the university he earned such an excellent reputation as a boxer that a sports promoter wanted him to train for a fight with Jack Johnson, then the world heavyweight champion. He was awarded a Rhodes scholarship for Oxford, England, where he studied law. Hubble returned to the United States in 1913 to practice law in Louisville. A year later he went back to his alma mater to begin studies for an astronomical career at the Yerkes Observatory. No one, he stated, should go into astronomy without a genuine call, and the only way to test a call is by having another calling to be called away from. In 1919, Hubble joined the staff of the Mount Wilson Observatory. Toward the end of 1924, Hubble made his first great discovery: With the new 100-inch reflector he was able to sort out a number of bright Cepheids in some large spirals, and employing the Cepheid period-luminosity relation, he demonstrated that these spirals were other galactic systems. This put an end to the raging controversy about whether these objects belonged to our Milky Way or were beyond it. In 1925, Hubble established a classification system for galaxies. However, it was 4 years later that he made his greatest discovery. After the tedious process of determining the distances of a number of galaxies and observing their redshifts, Hubble and others used them to show that there existed a proportional relationship between distance and velocity, now known as Hubble velocity-distance law of recession. Although at first Hubble doubted the notion that this relationship was evidence for an expanding Universe, he later accepted the view after cosmologists had pointed out that this was the only logical explanation.

Portrait of Edwin Hubble
Courtesy of the Archives, California Institute of Technology Edwin Hubble was an American astronomer who lived between 1889-1953. His observations of galaxies helped him develop the idea of an expanding universe , which forms the basis of modern cosmology , the study of the origin of the universe. He also discovered a relationship between a galaxy's speed and its distance. Hubble's studies were interrupted by service in both World Wars. The Hubble space telescope , currently on an observation project in space, bears his name.

Edwin Hubble se stal klíèovou osobností výzkumu galaxií. V té dobì bylo známo, že se v nìkterých spirálních mlhovinách vyskytují hvìzdy. Nebylo ale zøejmé, že existuje nìco jako jsou galaxie. V roce 1923 prokázal, že se vesmír rozkládá i za hranicemi naší galaxie a o rok pozdìji urèil vzdálenost mlhoviny v Andromedì - poznal, že se jedná o galaxii srovnatelnou s naší Mléènou dráhou. Dva roky poté (1925) Hubble vytvoøil první použitelnou klasifikaci galaxií.

During the past 100 years, astronomers have discovered quasars, pulsars, black holes and planets orbiting distant suns. But all these pale next to the discoveries Edwin Hubble made in a few remarkable years in the 1920s. At the time, most of his colleagues believed the Milky Way galaxy, a swirling collection of stars a few hundred thousand light-years across, made up the entire cosmos. But peering deep into space from the chilly summit of Mount Wilson, in Southern California, Hubble realized that the Milky Way is just one of millions of galaxies that dot an incomparably larger setting.

Hubble, Edwin (1889-1953)

American astronomer who determined the extragalactic distance scale by locating Cepheid variables in the galaxy M31 from the Mount Wilson Observatory in 1924 and NGC 6822 in 1925. Using the galactic period-luminosity relationship (which was actually not quite correct, as was discovered by Baade ), he determined distances. Extending distance determinations by using the brightest star in galaxies, he (with Humason ) proposed the Hubble law which states v Hl . Hubble's original 1936 value for H of 526 km s Mpc was reduced to 200 km s Mpc after the work of Baade , and to between 50 and 100 km s Mpc when Sandage discovered that some of the "stars" Hubble had identified in distance galaxies were actually H II regions.
