“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,
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.
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,...

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).
Carl Sagan: astronomer, astrophysicist, cosmologist, author, skeptic, and visionary. The middle of the twentieth century was clad in scientific advancements that opened up the realm of our universe to the world. At the head of this exploration was Carl Sagan, a pioneer of sorts. Aside from his countless contributions to the scientific community, he backed a new understanding of the cosmos to the more pedestrian population of the world.
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...
This paper is an overview of the Kepler spacecraft and its mission in space. According to the National Aeronautics and Space Association (NASA), Kepler, named after Renaissance astronomer Johannes Kepler, “is a space observatory launched…to discover Earth-like planets orbiting other stars.” Kepler does this by searching for planets within our galaxy that have a similar size to Earth within a habitable zone. A habitable zone is a distance between the planet and its star where water can exist on the planet’s surface. Additionally, Kepler is aimed at searching for planets with similar one-year orbits like that of Earth. As technology advances on Earth, increased standards of living and life expectancies have taken a toll on Earth’s fleeting, finite resources. Kepler potentially provides scientists with information regarding planets that can serve as a future home when resources have diminished and information that can foreshadow inevitabilities about Earth through older, Earth-like planets.
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.

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...

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...
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.
