The lab report this week required us to research the New Horizons mission that is still going on today. We were asked to list some information about the mission, what it hopes to learn and what we’ve learned from Pluto and its surroundings thus far. Personally, I was able to watch the live briefing and seen the first photos released of the dwarf planet in July and I am anticipating the next year of information we we’ll receive. Since the closest passing we have learned numerous insights about Pluto and its moons that were previously unknown. As the world waits patiently to discover more and more as the year of data comes in, we know that this is a giant leap in planetary exploration.

It is easy to flip to the index of an astronomy textbook to discover that, say, the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible), however, to picture this distance in our mind. In this exercise, we will learn to access the often unpalatable distances encountered in astronomy by simply scaling the huge distances to more recognizable, familiar numbers. So long as every distance within the system of interest is scaled by the same

American foreign policy shifted drastically from the birth of the new nation to the beginning of the 20th century. George Washington’s Farewell Address in 1796 left an admonition for the nation and isolationist roots from its founding President; however, by the early 1900s, William McKinley and other American Presidents took part in imperialistic foreign policy that represented a complete digression from Washington’s doctrine. After World War I and before the impending Second World War, American politics and foreign policy divided between the two aforementioned extremes. From 1935 to 1941, many American politicians and political parties opposed American participation in a Second World War and returned to America’s isolationist roots,

Why did Americans need the immigration reform build in the first place? Mexican immigrants have been coming to the United States throughout this country through history, but it was a guest worker program that started after World War II that set a stage for patterns for legal immigration we still see today. From 1942 to 1964, the “Bracero Program”, a guest worker program that brought 400,000 agricultural employers per year to the United States. This program had issues such as worker abuse and low wage, so it ended in 1964. But the worker kept coming. In the early of 1970s, there were more than 1 million undocumented immigrants in the United States. Still, most Americans did not have strong opinions about immigration policy the way we do today. There were lots of groups had interests to see the system change. President Ronald Reagan supported changing the laws, too, and he was a republican. He said “I believe the idea of amnesty”. After a year in fall, the bill finally gained the legitimate moment in 1986 which was Immigration Reform and Control Act(IRCA). It talked two of biggest issues at the time. The first one, it offered legal status for undocumented immigrants who had been living the United States since before January 1, 1982, and the second one, it penalized the employer who knowingly hired undocumented workers. The bill finally cleared in the house senator, and signed by President Ronald Reagan on November 6, 1986. The Immigration Reform and Control Act(IRCA) was the

Space was so mysterious and frightening for thousands who dared to look up at the heavens. Many dared to wonder about what actually lurked and waited for mankind. Eventually man took the steps necessary to take the final leap into the unknown. Throughout history NASA has contributed to several extraordinary feats of science and space exploration from the moon landing to the Curiosity rover NASA has been vital to finding cosmic knowledge for mankind.

Light is made up of different wavelengths (visible light is made up of the rainbow). If a substance could absorb specific wavelengths of light, then each substance will have a unique ‘fingerprint’. This could be proven by forcing light through a substance and seeing the different wavelengths of light that were displayed on the other side. If there are dark lines, that means that wavelength was missing and was absorbed. A second way to prove this would be to test if that same substance would release the wavelength it absorbed. In the candle experiment, the salt should give off a wavelength because of the intensity of the flame. If it is the same as the sodium street lamp, then that proves sodium will absorb and emit a specific wavelength consistently.

“The Hubble, has given us nothing less than an ontological awakening, a forceful reckoning with what is the telescope compels the mind to contemplate space and time on a scale just shy of the infinite.” implied Ross Anderson, an engineer. With this one telescope, created by a normal astronomer, scientists and astronomers are able to see space as never seen before. They are able to make mind boggling observations that contemplate space to an infinite scale. Thousands of discoveries about space have been observed through this lense and without the magnitude of high level instruments compiled into this large instrument most of these observations would never have been discovered. As proposed by Floyd E. Bloom a researcher, on izquotes.com, “As

EVERY GOOD BOOK CONTAINS A WORLD FAR DEEPER than the surface of its pages. The characters and their world come alive, and the characters and its world still live on. Conversation Starters is peppered with questions designed to bring us beneath the surface of the page and invite us into the world that lives on.

Our night sky, always seems to be sparkling at night, due to stars. Stars are luminous ball of gas, mostly hydrogen and helium, held together by its own gravity. Our night sky is filled with groupings of stars creating a galaxy, or also known as The Milky Way. The Milky Way, is one of many galaxies in a Local Group, containing between 100- 400 billion stars. Observing these stars with the naked eye is sometimes difficult, however technology today has made it much easier. In the experiment “Number the Stars”, we used two different types of telescopes, and a paper towel roll to record different counts of stars in different brightness’s in the sky. Between my partner and I we hypothesized that the larger focal point on the telescope, would

As the 25th birthday of the Hubble space telescope (en.wikipedia.org/wiki/Hubble_Space_Telescope) is being celebrated by space enthusiasts, others at the Goddard Space Flight Center (http://www.nasa.gov/centers/goddard/home), located in Greenbelt, Maryland, are working diligently to get the new space telescope James Webb Space Telescope all put together and ready for its travel into space in October 2018.

In physics I found Native Astronomy the most interesting. What I found the most interesting was that “Numerous indigenous tribes have inhabited America before the European colonists arrived and they each had their own way of interpreting what they saw in the sky” (DawLez) Natives perceptions and legends are what were outstanding compared to our thoughts of it in general. In the article “10 Ancient Cultures and Their Contributions to Astronomy” it mentions how they traditionally believed that the way to let others know knowledge was by using the stars to tell stories and legends. Not only was it the Native American that believed that having stars for guidance was important, it was many more as well that agreed to that idea. For example Pawnee

In the year 1609, the first proper space advancement was made; a telescope created by Galileo. Over four hundred years later, space exploration has been continuously evolving, changing and advancing at an increased rate per year. Every year, the knowledge of space data almost doubles; new planets and moons are being discovered each year, the known universe expanding beyond what we previously knew. It is estimated that within the next two decades, we may reach the point where we have discovered most galaxies in the universe. With the rapid influx of information, astronomers are asking themselves: what is the next stage for astronomy?

Low risk? Well, yes. The odds of being apprehended at all are very low, and
