    About the Course
    One of the first things you will notice about this course is that there are no lectures. Instead
    course material is provided in the form of online Lessons. These are made of a mix of
    multimedia material including text and images, videos, animations and simulations. You
    can step through them page by page, you can display a whole lesson as a single
    webpage, and you can print them to provide a hardcopy record of the whole course.
    Associated with each lesson is an interactive tutorial, called an Activity, which will take you
    step-by-step through aspects of the course content. Activities include videos and
    simulations, and will set you problems based on these. Most questions in the Activities are
    graded. Don’t think of the Activities as simply tests of what you covered in the lesson.
    They may well extend the material covered in the lessons, and require further research in
    the textbook, or on the internet.
    Another key part of the course is the discussion forums. Your contributions to the
    discussion will be graded. In each of the four discussions (Module 1, Module 2, Module
    3/4, Module 5/6) you are expected to post at least one question, and one answer to
    another students question. We are looking in particular for well-researched answers
    supported by references. The skills used here will also be valuable when you come to
    write your essay, which will be due at the end of week 9 of the course.
    An important thing to understand about this course is that it is not about memorizing a lot
    of facts that you will be subsequently tested on. There is far more material covered in the
    course than you can expect to remember. What we do hope you will do is develop an
    understanding of the basic concepts and ideas.
    Remember that all assignments in this course including the final test are “open book”.
    When you are working on the assignments you have access to all the resources including
    the course lessons, the textbook, and the internet. You need to learn how to use these
    resources efficiently to find whatever information you need.
    Learning Outcomes
    On completion of the course you should:
    1. have an understanding of key recent developments and concepts in areas such as
    astronomy, space exploration, astrobiology and related disciplines,
    2. appreciate the interrelatedness of different scientific disciplines,
    3. understand scientific method, what it means to study something scientifically and the
    process of scientific discovery,
    4. know that science is a continuing worldwide endeavour, and that scientists are diverse
    in age, gender, ethnic background and nationality,
    5. be competent in using resources on the internet to investigate scientific questions, and
    in preparing written reports on such investigations.

    Keeping In Touch
    General questions about how the
    course operates are best asked
    through the course discussion forum
    near the top of the Moodle main
    page. That way everyone gets to see
    the answers. Before you ask check
    the course information, course FAQs
    and course discussion. The answer
    may well be there already.
    If you want to contact a specific
    member of the team you can do this
    through Moodle messaging or
    through email.
    Who to contact:
    For most queries your course instructor, Lucyna (lkedzior@unsw.edu.au), will be your first
    point of contact.
    Contact your group teaching assistant for feedback on marks and marking for the tutor marked
    assignments (discussions, essays). If you are not sure who your teaching assistant is, use
    “Participants” on Moodle and select “Teaching Assistant” in the “Current Role” drop-down
    menu. You can click on the name to send a Moodle message, or choose “User Details” under
    “User list” to find the email address.
    For administrative matters such as enrollment issues you can contact Ranji Balalla
    (r.balalla@unsw.edu.au) in the Physics First Year Office (Old Main Building LG03) phone 9385
    4976.
    Extensions for Assignments:
    If you are unable to complete an assignment on time due to illness or other circumstances
    please let us know in good time. We can usually make arrangements to handle such
    situations. If you submit a formal “Special Consideration” request it will speed things up if you
    email Lucyna or Jeremy at the same time. Note that such requests should be submitted no
    later than 3 days after the assignment deadline.

    3. The UNSW library has multiple copies in the High
    Use Collection
    If you are looking at second hand books or other online suppliers you may find other versions
    of the The Cosmic Perspective 7th edition. Any of these are fine. They all contain the same
    content but may have minor differences of formatting so page numbers may not exactly match.
    International Edition US Edition
    Older editions of the book such as the sixth or fifth edition will obviously not be quite as up to
    date as the current version, but still retain the same chapter structure and much of the same
    material so should be useable for this course.
    You may come across The Essential Cosmic Perspective. This is a different book –
    basically an abridged version with fewer chapters. The Cosmic Perspective sometimes comes
    bundled with software products such as Pearson’s Mastering Astronomy. This software is not
    used for our course.
    Another book you may find useful is Life in the Universe by Bennett & Shostak, (Pearson
    Higher Ed. ISBN 9780134089089). This provides better coverage of the Astrobiology aspects
    of the course.

    Lessons and Activities
    Important elements of the course are the
    series of lessons and activities. These
    come in pairs, each lesson has a
    corresponding activity. We recommend
    that you first have a look through the
    lesson and then try the corresponding
    activity.
    You may find it useful to have the lesson
    and activity up on your screen at the same
    time. If you are not sure how to do this
    see the video - Working with Lessons and
    Activities.
    The activities are graded and provide the
    largest single component of your course
    grading. As you work through them you
    will find that some questions have grades
    and some do not. However, in most cases you will have to correctly answer a question
    before you can move on to the next screen. You will need to complete an activity before its
    grades will be entered on your gradebook. The activities are not timed and you can stop
    and resume working on them at any time.
    Note that these activities do not have individual completion deadlines. Other course
    assignments such as the discussions and essays do have deadlines. It is up to you to plan
    your time for the course appropriately. While you can do the activities at any time, we
    recommend that you try to complete the activities for each module by the end of the two
    week period assigned to that module, and do not leave them all until the end of
    semester. All activities need to be completed by the end of week 13.

    PHYS1160 Discussion Groups
    Each group has been assigned a teaching assistant, who will moderate discussion and will
    mark your assignments. Your teaching assistants are:

    Group 22 Jinglin Zhao
    Online discussion groups are an important part of this course. They are the second largest
    component in grading counting for 26% of your overall grade. Discussion groups provide a
    means to discuss and better understand the course material covered in the lessons and
    activities.
    The course is divided into six topical modules. There will be four discussions, separate
    discussion for Modules 1 and 2, and then combined discussions for Modules 3/4 and
    Modules 5/6. These discussions can be found under each Module section in Moodle. For
    the purposes of discussion groups, students will be divided randomly into groups.
    Using Discussions
    Online discussions allow you to enter messages (known as posts) that can be seen by
    everyone else on the group. Messages are linked in threads. When you add a message to
    the discussion, you can use the Add a new discussion topic button to start a new thread.
    Alternatively you can use the Reply button to an existing message to add another
    message to that thread. When you add a message you can simply type your message into
    the text box, or you can cut and paste from another program such as a word processor
    (this is a good idea if you want to add a long message). You can include pictures in your
    messages.
    12
    The main purpose of PHYS1160 Modules discussion forum is the interaction between
    students on the subject areas covered the specific Modules as described below. There is
    also a “Course Discussion Forum” in the Introduction part to the course that can be used
    to ask general questions about the course (e.g. details of course operations, assignments
    etc.). This general discussion area should not be confused with the Module
    discussions, where you will submit entries that are graded!
    Course Requirements
    Discussion group participation provides part of your course grade. As a minimum
    requirement we expect you to contribute at least one question, and at least one
    researched answer or follow-up comment to another student’s question, to each of the four
    discussions (Module 1, Module 2, Module 3/4, Module 5/6). You are welcome to make
    additional contributions to maximise your marks, which will reflect the quality of your posts
    and your participation in the discussion.
    Guidelines for Discussion Group Use
    In the first discussion group please post a brief introduction about yourself. There will be
    an introduction thread, and you should post your introductions as a reply to this thread (to
    avoid cluttering up the discussion with many threads). These are not graded and do not
    count as your required entries!
    The questions you post on the module discussion group can be anything related to the
    subject matter for the module (and since we have a course that covers a very wide range
    this is not much of a restriction). Questions might relate to terms or concepts that came up
    in the lessons that you don’t understand, might request further explanation of some aspect
    of the subject matter, or might be just something (course related) that you have always
    wanted to know, but hasn’t been covered in the course. Your teaching assistants and
    course coordinator may also post questions in order to get discussion started.
    Normally each question should start a new thread (use the Add a new discussion topic
    button). When you enter a message there is a “Subject” field. Please try to put something
    meaningful in here that describes what your question is about. This makes it easier for
    everyone to navigate the discussion group.
    The usual rules on attribution and plagiarism apply to discussion group posts as for
    any assignment! If you use material from the web, journals or books, then reference the
    source in your post.
    Discussion Group participation is graded on quality (not quantity) of posts and
    engagement in discussion (such as follow-up questions and responses). Remember that
    posting just one answer and one question is a minimum requirement and is usually not
    sufficient to achieve top mark for the discussion. So what is a good quality post? A post
    that will score high marks is one that provides a clearly presented answer to a
    question, shows evidence of good understanding of the issue and of some
    research, includes in-text references to the sources used and generates more
    discussion. A length of about one page should normally be about right – but use more if
    13
    you feel the topic needs it. This is the sort of post you should be submitting for your Best
    Contributions assignment later in the course.
    Note that we have a wide range of students for this course with varying amounts of
    background knowledge of the subject. If you are someone who knows all the answers,
    please don’t immediately jump in and answer all the questions. Give other students a
    chance. As pointed out already there are no marks for quantity of posts, so you would be
    better giving a well researched response to one or two questions, rather than a short
    answer to many.
    If a question has already been answered this doesn’t mean that the topic is closed. You
    may well be able to add more to the initial answer, to suggest a different approach to the
    question, or you may think the original answer is wrong. The answer to a question may
    well suggest follow-up questions.
    The questions on the discussion group are for you, the students, to answer. However, your
    teaching assistants will help if there are questions that have everyone stumped, and at the
    end of each module, the teaching assistants will tidy up any unresolved threads.
    Note:
    - Early contributions to discussion are encouraged and attract 1 bonus mark for a post
    within the first week of the new module discussion opening.
    - Questions posted in the last 24 hours before deadline will not be marked, because they
    usually do not contribute to the discussion.
    14
    PHYS1160 Essays
    Essays should be between 1500
    and 2000 words. The word limit
    should include the text, figure
    captions, footnotes, but not the
    reference list (we are happy to see
    lots of references). You will lose
    marks for going more than 10%
    over the 2000 word limit.
    The format of the essay is not
    specified. You are welcome to
    include section headings and
    pictures. However try to ensure
    that they help to illustrate the
    argument presented in the essay
    and are not mere adornment.
    Your essay should be written for a
    well informed but non-specialist
    audience. The style (not the
    format) used in popular science magazines such as Scientific American or New Scientist
    would be a suitable guide. Remember, you are not writing for experts, so if you use
    technical jargon you will need to explain it. Refrain from using formulae, but instead
    explain concepts in your own words.
    Essays are expected to show evidence of researching the topic beyond the material
    presented in the course lessons and textbook. The sources you use (websites, journal
    articles, books) should be referenced. You should consistently use one of the standard
    reference styles. One style is to number references sequentially in the text and include a
    numbered list of references at the end of the essay. An alternative is to mark references in
    the text using author and date e.g (Sagan, 1987) or Drake et al. (1965) and list references
    at the end of the essay in alphabetical order.
    If you use text from another source make it clear that it is a quote by placing it in quotation
    marks and giving the reference to the source. However, you should not make excessive
    use of quotes. The essay should be in your words and present your views on the subject,
    not just an account of what other have said. Using text from other sources without
    attribution is plagiarism and is not acceptable.
    Your essay will use the TurnItIn system for submission that includes an automatic test
    for plagiarism. Your submission will be checked against a large database of material and
    tested for matches. The database includes all past essays submitted for this course. Make
    sure that what you submit is your own work and that any material from other sources is
    placed in quotation marks and the source cited. Copying material from the web (even if
    you subsequently make edits to it) is considered to be plagiarism and it is unacceptable.
    Read more on the plagiarism policy from http://student.unsw.edu.au/plagiarism .
    TurnItIn is well designed to detect all plagiarism attempts!
    TurnItIn gives a similarity score that indicates the percentage of the submission matched
    to its database. While there may be legitimate reasons for matches (such as quotations
    15
    and references) we tend to be suspicious if we see a high similarity scores.
    Essays will be graded on:
    o Degree of understanding of the topic (max. 6 marks)
    o Quality and depth of research (max. 6 marks)
    o Clarity of presentation (max. 6 marks)
    o Original and outstanding coverage of the topic (max. 2 marks)
    Submitting Essays
    Essays are due before midnight on Sunday Oct 2nd (end of mid semester break). They
    should be submitted online through the submission box provided in the Assessments page
    on Moodle. You can submit it in a range of file formats (MS Word, WordPerfect, PDF,
    Postscript, HTML, RTF and plain text).
    Essay Topics — Choose one of the following
    1. Space Telescopes
    Explain why astronomers put telescopes in space. Describe in detail one space telescope
    that does not observe visible light and list its achievements. Discuss major discoveries that
    were possible with astronomical observations made from space and how they changed
    our understanding of the Universe.
    2. The Earliest Evidence for Life
    Review the earliest evidence for life on Earth. What form does the evidence take and
    where is it found. Discuss the controversies relating to some of this evidence and give
    your conclusion on the earliest date at which we can be confident that life was present on
    Earth.
    3. Atmosphere Evolution on Rocky Planets
    Compare evolution of atmosphere on Earth, Venus and Mars, and explain differences in
    current atmospheric conditions on these planets. Describe how the Earth’s atmosphere
    helped life to originate, survive and develop, and how has life affected the atmosphere
    over time.
    4. Life in Extreme Conditions
    Explain what extremophile life forms are and where they are found on Earth. In view of
    what we have learnt about extremophiles discuss the possibility of extraterrestrial life in
    different places of our Solar system.
    5. Key Space Missions
    Choose ONE of the following space missions and give an account of the mission
    describing the challenges it had to overcome and the mission’s achievements. Describe in
    particular how it has influenced our understanding of the possibilities of past or present life
    in the solar system.
    o The Viking dual orbiter/lander mission to Mars.
    o The Galileo orbiter/probe mission to the Jupiter system.
    16
    o The Cassini/Huygens mission to the Saturn system.
    o The Mars Exploration Rover mission (Spirit and Opportunity rovers).
    6. Exploration of Venus
    Describe the history of missions to Venus and their achievements. How did we learn about
    the thick atmosphere and high surface temperature of Venus and how did we map its
    surface? Should we consider Venus as a possible site for life in our Solar system?
    7. Gravitational Waves
    On Feb 11 2016 the announcement was made of the detection of gravitational waves from
    space using the Advanced LIGO facility. What are gravitational waves? How does LIGO
    detect them and why is this discovery significant?
    8. Rosetta Mission
    Explain why scientists study comets of the Solar system. Discuss the methods applied in
    such studies. Describe the Rosetta mission and argue its importance in understanding the
    history of our Solar system and development of life on Earth.
    9. Inside stars代写PHYS 1160 for Life Elsewhere Assessment
    Discuss internal composition of stars similar to our own Sun and compare it with
    composition of white dwarfs and neutron stars. Explain how helioseismology and solar
    neutrinos help to study interior of the Sun.
    10. Space mission to Pluto
    The “New Horizons” mission is exploring the outer Solar System. Describe the objectives
    of the mission and important scientific instruments on the space probe. Discuss what we
    have learnt about Pluto after the closest approach to this dwarf planet. Explain how this
    mission helps us to understand the processes of formation and evolution of the planetary
    system.
    11. Formation of planetary systems
    Discuss the early ideas about the formation of our Solar system. Compare our solar
    system with other multi-planetary systems discovered in the last 20 years. Explain what we
    have learnt about formation of planets from these discoveries. Describe the concept of
    planetary migration.
    12. Kepler and TESS
    Compare the strategy and objectives of the NASA Kepler mission and the new planned
    TESS mission. Choose one extra solar planet detected by the Kepler mission and discuss
    its importance for our understanding of other solar systems.
    13. Habitability of Planets
    Explain what makes a planet habitable. In the context of currently known extra solar
    planetary systems discuss the likelihood of habitable planets in our Galactic
    neighbourhood. Describe some examples of recently discovered extra solar planets, which
    are suggested to be habitable and explain why.
    14. Role model astronomer/astrobiologist
    Science advances by efforts of large collective of collaborating people, but there are
    outstanding individuals that we all admire for their role in moving us forward in
    17
    understanding our world. Choose your favourite astronomer or astrobiologist that you
    learnt about in studying this course, and describe their contribution to their field of
    research. Explain why this person inspired you personally.
    15. Dark Matter and Dark Energy
    Explain both concepts and the differences between them. Describe the observations that
    led to the hypothesis that dark matter is an important component of the Universe. Describe
    the suggested constituents of the dark matter.
    16. The Search for Extra-Terrestrial Intelligence
    Explain what is SETI and how it approaches the search for the ET. Explain why radio
    telescopes are particularly useful in such a search. If we make contact with an advanced
    extraterrestrial civilization discuss how likely it is that we will benefit from the encounter
    through, for example, the information they may provide on advanced technologies, or are
    we likely to suffer through the hostility of a species that competes for our resources and
    perhaps our planet? Based on your assessment should we be advertising our presence by
    sending messages to the stars or would we be better keeping quiet?
    Factors you may wish to consider could include:
    o Do we expect advanced intelligent species to be friendly or hostile to other species
    (based on evolutionary theory, and the requirements of survival of such a
    species)?
    o Has the human race developed more or less tolerance of different peoples and
    cultures as civilization has developed?
    o The historical record of encounters between colonial and indigenous peoples on
    Earth.
    o Our record of treatment of closely related species such as the great apes.
    o The vast distances between stars and the difficulty of physical contact with
    extraterrestrial neighbours.

    By the end of week 12 you should submit your choice of what you consider to be the two
    best discussion group contributions you made during the course. These will normally be
    answers or follow-up comments. They can be taken from any of the four Module
    discussions (Module 1, Module 2, Module 3/4, Module 5/6). To do this combine the two
    contributions together into a single file and submit this through the TurnItIn submission link
    that you will find in the Module 6 section on Moodle (it works the same way as the
    submission box for your essay). The submission is due Sunday Oct 23rd. These
    contributions will be marked based on (1) the amount of research, (2) clarity of
    presentation and (3) understanding of the topics, in contrast to four Discussion Modules
    that are marked not only on quality of posts but also participation in the discussion. In your
    submission to Best Discussion Contributions, you need to also include the questions,
    which you answered.

    PHYS1160 — Final Test
    The Final Test provides 24% of your grade and will be an online test set on your course
    Moodle website. It will be timed, with 90 minutes allowed for completion, and you have
    only one attempt, so please make sure you are well prepared and have adequate time and
    a stable internet connection before attempting it. The test will consist of multiple choice
    questions (with single or multiple correct answers) that will be randomly selected so each
    student will receive a different set of questions.
    The Final Test will be available from Thursday Oct 20th and is due on Sunday Oct 30th.
    A practice test will be also provided (by Thursday Oct 20th) that you can use to familiarise
    yourself with the type of questions to expect in the final test.
