    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 Jan 22nd
    . 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).

    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 
    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.
