    What is Wein's Law?

    thepeak frequency is indirectly proportional to the temperature.

    This isimportant because it tells us the hotter an object is the bluer theradiation.

    What is stefan's law?

    isthe total energy radiated per second is proportional to the fourthpower of an objects temperature.

    How are wein's law and stefan's law important to astronomers?

    Thisis usful to astronomers because they can imply that when you increasean objects radiated energy it will greatly increase its temperature.

    1. Whatare the 3 powers of a telescope? What do the 3 powers measure?

      Resolvingpower, light gathering power and magnifying power.

      The resolvingpower of a telescope is the ability to produce an image in whichobjects that are close together can be seen separately.
      When selecting a topic, students should first determine the lens of inquiry related to their respective field of study or interest and second, students should have realistic expectations of the degree to which a topic can be explored in the project size established. The amount of material that can be covered in a 100 page dissertation would be much more extensive than that which could be covered in a rudimentary three page discussion. Below is a list of some topics that fall within the scope of inquiry specific to astronomy topics. This list only is a small sampling of the many directions in which a student could go for their exploration of an astronomy related topic. The staff at PowerPapers.com can complete a project on any of the below listed topics or this list can be used to help inspire original ideas for student inquiry.

      Lightgathering power is the ability to capture light. Magnifying power isthe ability to see things very far away

    1. Describethe aparent motion of the Sun as seen by the Earth over the courseof a day and over the course of a year.

      Duringthe day the Sun moves across the sky from east to west.

      The apparentyearly path of the Sun through the stars is called the ecliptic.
      Astronomy can be defined as the science that is concerned with the material universe that extends beyond the atmosphere of Earth. As a result, the topic of astronomy deals with all that which extends beyond the context of which is most familiar to humans. While advances in telescopes, satellites and space travel have allowed humans to peer beyond the Earth, the degree to which this has occurred barely touches the surface of the vastness that is outer space. As a result of humans limited capacity for space observation and exploration, it can be stated that there is more that humans do not know about space than what is known with any degree of certainty. Much of the realms of astrophysics and the likes deals with theory and mathematical projections of these implications. As an interdisciplinary topic, astronomy is closely linked to mathematics, physics, chemistry and molecular biology. The theoretical nature of the subject and its propensity to challenge values held by human beings means that controversy often exists when unpopular conclusions are drawn.

      This circular path is tilted 23.5 degrees with respect to thecelestial equator because the Earth's rotation axis is tilted by23.5 degrees with respect to its orbital plane.

    1. Theearth undergoes 4 types on motion about itself and about the Sun.

      If there are underlined (linked) words or phrases, click them for additional details.

      What are they? Explain each.

      Revolution,Rotation, Precession and Nutation. The earth revolves around the sunonce every 365 days. The earth rotates about its axis once ever 24hours with respect to the sun.

      Listed below are 12 questions. You will have to write answers to four of these questions on the final exam, along with 30 multiple-choice questions that will cover the entire course. These questions will be general in nature, covering the key points from each quiz. The four essay questions will be separated into three categories…you will not know which categories are which. You will have to answer one question from each category, and one wild card...a question from the list below of your own choosing. Below are the essay questions which will be on the final exam and a list of topics that you will be asked about for the multiple choice questions (note to students in distance ed class only--these are not the exact questions that will be on your exam, although a few are quite similar. Nevertheless, by studying them and finding the answers, you will be well prepared to suceed!)

      The direction of the earthsrotational has a slow precession. So the direction of the rotationalaxis is not fixed. The nutations of the earth are daily variationsof its rotation because of the torque of the Moon. Equatorial bulge.

    1. Whatis retrograde motion? Which celestial objects undergo retrogrademotion? Why do these objects undergo retrograde motion?

      Retrogrademotion is an object moving in the opposite direction with respect toanother moving object. All celestial bodies undergo retrogrademotion. This is because some planets have smaller faster orbitsaround the sun and others have longer ones.

      Exoplanets - Exoplanets research papers explore these planets that orbit outside of our solar system.

    1. Whydo Australians celebrate christmas in the summer? Why are thereseasons on Earth?

    ustralianscelebrate christmas in the summer because they are a part of theSouthern Hemisphere and their seasons are reversed. Due to the tiltof the earths axis some parts of the earth get more or less directsunlight. This creates colder or hotter weather.

    1. Decribethe phases of the moon and explain why the moon undergoes phases.

      Thephases of the moon are New, where the surface of the moon iscompletely dark, waxing where more and more of the moon is beingshown, then there is waning where less and less is being shown, andfinalling there is full moon where the entire face of the moon isbeing shown. Gibbous and Cresent. So the basic explanation is thatthe lunar phases are created by changing angles (relative positions)of the earth, the moon and the sun, as the moon orbits the earth.

      Giant Impact Theory- Giant Impact Theory research papers discuss a model that takes data from lunar missions to determine how the moon came about.

    1. Whatare the likes and dislikes between comets, asteroids, meteors,meteoroids, and meteorites?

    comet = small solar body. orbits the sun.
    asteroids = orbit the sun. rock and metal. do not have a visible coma like comets. larger than meteoroids
    meteoroid = a small rocky particle in our solar system.
    meteor = a meteoroid in our atmosphere
    meteorite = meteoroid that has fallen to surface

    Howare terrestrial an jovian planets a like and how are they different?

    Jovians = bigger, gaseous, hydrogen and helium atmosphere, dense core, spin more, far away from sun, flat poles.
    terrestrials = smaller, closer to the sun, rocky, nitrogen and carbon dioxide atmosphere.

    What is anexoplanet? How many are known to exist? What do we know about theirphysical and orbital properties?

      An exoplanet isa planet outside out solar system.

      Exploration of the Solar System - Research papers on the exploration of the solar system compare the general characteristics of the terrestrial planets to those of the gas giants.

      Around 900 are know to exist.They are much larger than earth and have very short orbitalpatterns.

    Explain how thesun generates its energy?

      Its energy isproduces by nuclear fusion of hydrogen and helium in its core.Specifically something called the proton to proton chain.

      Astronomy paper topics can be quite involved and intimidating; particularly to students outside of the discipline. For non majors, exploration of astronomy topics can include the utilization of other lenses of inquiry. For example, history majors could select historical analysis of astronomy topics like “Early Astronomers: Ptolemy, Aristotle, Copernicus and Galileo.” Similarly, literature majors could choose an astronomy related topic like, “Representations of Space Travel in Science Fiction: Ray Bradbury and Arthur C. Clarke.” Both of these examples would involve exploring astronomy through an interdisciplinary perspective. For pure students of astronomy or students of astrophysics, examining specific phenomena like dark matter or wormholes could be a better course of action.

      Thisoccurs when the temperature of the protons is high enough for itover come its coulomb repulsion.

    1. Discussthe evolution of main sequence stars of different masses

      Lowmass stars will take much longer to to go from red dwarfs to whitedwarfs.

      History of Astronomy - History of Astronomy research papers look into the earliest studies of the stars and sky.

      A lot of these stars are big enough to fuse helium. Starswith 0.5 - 10 solar masses become red giants. These stars stillburn helium and hyrdrogen in nuclear fusion. More massive stars aretoo unstable and end up destroying themselves in a supernova.
      Supernova - Supernova research papers examine the huge stars in the cosmos and how they are formed.

    Spiral Galaxies

    Spiralscontain a flattened galactic disk in which the spiral arms are found.A central galactic bulge. Rich in gas and dust.

    Elliptical Galaxies

    Ellipticals have no spiral arms and no galacticdisk. Other than the dense central nucleus they have not internalstructure.

    The midterm essay exam addresses the following topics. You will be expected to answer 4 essay questions - one from each of the four groups below. Each will be worth 20 points. You can CHOOSE which of the questions you answer in each of the first three groups. Answers should be at least two long paragraphs on each topic. Answers that include outside resources must include appropriate citations - copied material without citation from other sources is not acceptable. We'll review each topic in detail in our class, and lecture notes as well as online homework resources will help you prepare. It is worth 80 points.

    They contain old reddish or yellowish low mass stars. Nosigns of new young stars being made.

    Irregular Galaxies

    Irregularsare called this because they cannot be put into the other twocatagories because of their shape. They are rich in intersellarmatter and have many young stars.

    Life of a Star - Life of a Star research papers trace the formation of stars, as seen by the Hubble Space Telescope.

    They lack any difinitive structureand are genrally smaller than spirals.

    1. Whatare the 3 main types of active galaxies? What makes them so active?What can you say about galactic evolution?

      Seyfert,Radio and Quasars. They are much more luminous than normal galaxiesand have nonstellar spectra, emmitting most of the energy outsidethe visible range. They have high speed jets shooting out mattewrfrom their central nucleus.

    1. Howdo we know that the universe is expanding? What does this expansionimply?

      Twopieces of data suggest that the universe is expanding.

      Inflation Theory - The Inflation Theory research papers examine the theory that states that for a brief period of time following the Big Bang, the universe expanded at an exponential rate.

      ..
      Nomatter where you look in the sky, nearly all galaxies are movingaway from us... The only exceptions of those galaxies that are partof the local group.
      The farther away a given galaxy is, thefaster it is moving away...

    1. Whatis the cosmic microwave background radiation? Where did it comefrom? What does it tell us about the early universe?
