“The great spirals... apparently lie outside our stellar system.” Edwin Hubble is a scientist, who provided evidence that the universe is expanding. The missourian achieved great things in his sixty-three years, making vast strides for the astronomy community. Hubble was born in Marshfield, Missouri on November 20, 1889. At a young age his family moved to Wheaton, Illinois, where he spent most of his childhood. While in college, he worked under Robert Millikan, Nobel prize winner for his work in physics. When WW1 began, Edwin Hubble volunteered his service. He also put his career on hold in 1942, when he served in WW2. While Hubble was working primarily in science, he provide much support for Einstein’s theory on the expanding universe. However,
Copernicus was born in Poland and was raised by a prosperous German family. As a result, he really enjoyed his youth, taking twelve years at four different universities. In 1503, he finall...
Four weeks after space-walking shuttle Endeavour astronauts repaired the Hubble Space Telescope in December 1993, an ecstatic Maryland Senator Barbara Mikulski waved a Hubble picture of the core of the spiral galaxy M100 at her naysaying colleagues. Today, Mikulski could host a Capitol Hill star party: The orbiting telescope has generated more than 100,000 photos of celestial objects, including a cemetery of dying stars, elephant trunks of dust and hydrogen gas twisting in the Eagle Nebula, jovian storms and aurorae, the rocky rings of Saturn and the colossal supernova smoke rings blown from an exploded star, to list a few. Hubble's pictures do double duty not only as congressional lobbying props, but also as screen savers, T-shirt prints, calendar photos, a background for the "Babylon 5" science fiction TV series and even planet trading cards to be provided soon to schoolchildren.

lifetime. Some of Edwin Hubble's greatest accomplishments were: Edwin Hubble proposed a classification system for nebulae, which are fuzzy little patches of light that are up in the sky. He discovered a variable star, called the Cepheid. It is located in the Andromeda Nebulae. Edwin Hubble settled decisively the question of the nature of the galaxies. Edwin Hubble's distribution of galaxies was determined to be homogeneous in distance. Edwin wanted to classify the galaxies according to their content, distance, shape, and pattern of brightness. By observing redshifts Edwin saw that galaxies were moving away from each other at a rate constant to the distance between them (this is known as Hubble's Law).
In the year of 1473, on the 19th of February, a soon-to-be, well remembered, mathematician/astronomer was born in the city of Torun, Poland. Born with the name of Nicolaus Copernicus, he was the fourth and youngest child of Nicolaus Copernicus Sr., and Barbara Watzenrode. Copernicus was, technically, born into German heritage. That being said, his primary language was german, bt many scholars believe he spoke fluently in Polish also. At ten years of age, the unfortunate happened to Nicolaus; His father passed away. After the passing of Nicolaus Sr., a maternal uncle stepped in and took over the parenting role. Nicolaus’ uncle took matters into his own hands to make sure Copernicus acquired the most outstanding education possible. Copernicus enrolled in the University of Cracow in the year of 1491. While at the university, he studied painting and mathematics. At that time, Copernicus took no classes over astronomy. Nicolaus developed a growing interest in cosmos and books. He then started a collection of books on astronomy. Following Nicolaus’s graduation from Cracow in 1494, he returned back to the city Torun. Copernicus's uncle had already had a job as a cannon arranged for him prior to his arrival. This job at Frombork Cathedral, was usually only given to priests. Such a fortunate and unusual opportunity, Copernicus took the job. He then held that job for the rest of his life. The position of a cannon allowed him to fund money to continue his studies for as long as he desired. There was really only one major downfall of the job. It took up a lot of his time, leaving him very little free time. It came to the point where academics had to come second. In the year of 1496, Nicolaus took a leave from his job. Not a two-week leave,...
In the article from the official NASA website, NASA gives a list of Hubble’s accomplishments, which gives the reader a comprehensive picture of Hubble’s importance. Hubble has not only given astronomers the most detailed images of outer-space in existence, but also taug...
I intend to prove beyond a reasonable doubt that Galileo was one of the greatest innovators of all time. Without his discoveries, the world would look at the universe differently than it does now.
Johannes Kepler was born on December 27th, 1571 in the Stuttgart region of Germany. Kepler at a young age gained an interest in mathematics and astronomy and as he grew older so did his passion. When he was at the University Tubingen he was introduced to some theories one was the Geocentric and the other Heliocentric theory. He believed in the Heliocentric theory, he based a lot of his observation on that theory and also defended it. Well after college Kepler got to work for the famous astronomer Tycho Brahe. Tycho Brahe had done a lot of observation with the naked eye. A year after Kepler worked for him. Tycho Brahe took his last breath. Kepler was Brahe successor. He got to read his friend's observation on mars. As accurate as Brahe observations
The Hubble Telescope is the world’s first space-based optical telescope. The Hubble telescope received its name from American astronomer Dr. Edwin P. Hubble. Dr. Hubble confirmed an ever expanding universe which provided the basic foundation of the Big Bang theory. The first concept of the Hubble telescope came from Lyman Spitzer in 1946, who at that time was a professor and researcher at Yale University. In 1946, Professor Spitzer believed that Earth’s atmosphere blurs and distorts light, and a space orbited telescope would be able to overcome this problem.
The first person to ever observe the Milky Way was Greek philosopher, Democritus, who said the galaxy may consist of distant stars. In 1610, Galileo Galilei used a telescope to study the Milky Way and came to the conclusion that it was composed of billions and billions of faint stars. Then, in 1750, Thomas Wright c...
Studying the Cepheid variables, using the then largest telescope the Mount Wilson telescope of 2.5 m aperture, Hubble estimated their distances of about 300 kpc and noted that they are too far to be inside the Galaxy. This led to the studies of extragalactic astronomy. Also, Hubble morphologically classified galaxies into spirals, ellipticals and irregulars (lenticular) and placed them in a certain order, which is known as Hubble tuning fork diagram (see Figure 1.1). Elliptical galaxies (E) appear smooth and structureless. They are relatively less active with very little or no gas.
Hubble saw this and concluded that all galaxies are rushing away from us and the universe is expanding as a whole. Modern equipment has observed and verified that this so-called Hubble expansion exists throughout the observable universe. This shows three important things. First, there is no significance to the fact that Earth seems to be the center of the universal expansion. In any galaxy, it would look as if you were standing still and all others were rushing away from you.
An American astronomer named Edwin Hubble showed the world that our galaxy is not the only galaxy out there. He calculated the distances to nine different galaxies. The Doppler Effect was established which is the relationship between wavelength and speed. Hubble observed other galaxies and their spectra. The discovery that the universe is expanding was the greatest revolution of the twentieth century. Additionally, Einstein introduced an antigravity force that said that space time had a bu...
