Phys1005 introduction to astronomy space science

PHYS1005: Introduction to Astronomy & Space Science

  • Broad introduction to modern astronomy and astrophysics

  • Apply simple physical principles to very distant objects (well beyond reach) and learn about their nature

  • Nature of the course:

    • Mostly lectures, but including 4 problem classes + revision lectures

    • 3 lectures/week

  • Assessment:

    • 80% by examination (end January)

    • 20% from multiple-choice, computer-based quiz (beginning January; 2 practice sessions planned for Nov and Dec – see PHYS1005 web page!)

    • i.e. no continuous assessment or lab component!

  • Details on handout

  • N.B. any updates will appear on the web page!

PHYS1005 – 2003/4


Books and other material

Books and other material:

  • Universe by Kaufmann & Freedman (5th ed.)

    • Comprehensive, beautifully produced, reasonable maths level

    • Useful for semester 2 course PHYS1008 Physics of Solar System

    • Used in previous years  possible second-hand copies from 2nd yrs!

  • Introductory Astronomy & Astrophysics by Zeilik, Gregory & Smith (4th ed.)

    • Slightly more advanced (assumes a higher level of maths)

    • Useful in later courses (for astronomers/space scientists)

  • WWW (http://www.phys.soton.ac.uk)

    • Everyone should look at course web pages!

    • Repository for all lecture material

    • And links to much else besides!

    • N.B. these are NOT a replacement for text books!

  • Astronomy magazines (Hartley Library):

    • Sky & Telescope

    • Astronomy Now

    • Frequent astro articles in New Scientist, Scientific American

PHYS1005 – 2003/4


Background to course

Background to course:

  • Core course for Physics with Astronomy and Physics with Space Science

  • N.B. no previous knowledge of astronomy is assumed!

  • A-level Physics is required and is assumed

  • A-level Maths is preferred but not essential (students with AS-level Maths only did fine last year)

  • 4 sets of Problem Sheets to work through

    • But these do not count in your assessment

  • Expect ~3hrs/week independent study (reading, reviewing lecture material, doing problems) per course

PHYS1005 – 2003/4


Overview of topics covered in course

Overview of topics covered in course:

  • Gain feel for astronomical scales: distances, times, masses:

  • e.g. travelling in a regular passenger jet, roughly how long would it take to reach the Sun?

    • 2 months

    • 2 years

    • 20 years

    • 200 years

  • Answer: 20 years!

  • Travelling in the same jet, how long would it take to reach the nearest star to the Sun? (What’s its name?)

    • 5,000 years

    • 50,000 years

    • 500,000 years

    • 5,000,000 years

  • Answer: 5 million years! (α Cen)

Timescales:

  • How old is the Earth?

    • 6,500 yrs

    • 65 million yrs

    • 800 million yrs

    • 4.5 billion yrs

  • Answer: 4.5 billion yrs - significance of a) and b)?

  • a) is “biblical” age, b) is last major impact event

  • N.B. the Sun is the same age as the Earth, but how much longer will it last?

  • How old is the Universe?

    • 4.5 billion yrs

    • 8 billion yrs

    • 13.5 billion yrs

  • Answer: 13.5 billion yrs – from where?

  • MAP satellite to survey cosmic microwave background (2003!)
