1 Last Time on Survey of Astronomy The big picture : The earth is: a single planet around a single star of hundreds of billions of stars. in a single galaxy of hundreds of billions of galaxies. The earth, the sun, our solar system, our patch of the galaxy, and the galaxy itself are all moving at hundreds of thousands of km/h through the universe. All of human history has occurred in the last minute of the calendar of the history of the universe.

3 Announcements/ Reminders Cell phones off please! New student? Forgot to pickup tickets/ syllabus/schedule last week? See me after class. Class ID Form: Turn in if still interested. Collins,Chen not on registration list. In-class planetarium visit Sep 8th OR 10th. Details next wed.

4 Assignments For next week: Finish reading Chapter 2. Finish up the introduction to Mastering Astronomy practice exercise.

5 Assignments For next week: Finish reading Chapter 2. Finish up the introduction to Mastering Astronomy practice exercise.

6 A few notes on MasteringAstronomy At least one practice problem each homework. Full Credit for answering correctly. 1/(n-1) off for each incorrect answer (better than regular multiple choice!). 2% bonus for not using a hint: rarely worth it! Stuck or need help? See me after class.

7 Today s Menu Units and numbers. Patterns of stars. Rising and Setting. Angles on the sky.

8 Units... Not nearly as exciting as the Big Bang, but necessary In the U.S., we basically use the British, or imperial, system of measurements length = feet, yards, miles, etc. mass = ounces, pounds time = seconds, minutes

9 Scientists use the metric system length = meters (m) mass = gram (g) time = seconds (sec)

10 Some Useful Conversions A meter is about the length of a yard 1 m = yards A kilometer (km) is 1000 m, a bit less than a mile 1 km = 0.62 miles A meter per second (m/s) is about walking speed 1 m/s = 2.2 mph 1 km/s = 2,200 mph

11 Metric Prefixes kilo=1000 (kilometer, kilogram, kilobuck) milli= 1/1000th (millimeter) mega=1,000,000 (megabyte) micro=1/1,000,000th (micrometer) For more see Appendix C.4

12 Astronomers deal with very large and numbers small VERY VERY BIG very very small

13 Examples of Large and Small Numbers 2, ,000, ,000,000, Warning: Writing these numbers out can induce hand cramping

14 Scientific Notation to the Rescue Write a number like 3,456 as 3,456 = x 10 3 How do we do that? x 1,000 = x (10 x 10 x 10) = x 10 3

15 Examples of Scientific Notation 318,000,

16 Examples of Scientific Notation 318,000,000 31,800, ,180, , , , Confused? See Appendix C

17 Typing Numbers in Scientific Notation On MasteringAstronomy, you get a text box with buttons for entering numbers can be typed as 6.7 * 10^-5

18 Observing the Sky: The birth of astronomy

19 Why look at the sky? knowing the time of day: Survival skill (many predators hunt at dusk!) Predicting seasons is a survival skill. migration food storing (like a squirrel) crop planting (last frost?) Rains and droughts Nothing on TV. Eventually navigation, mapping.

20 Constellations and Star Maps

21 What are constellations? Patterns of stars. Examples: Ursa Major, Orion. not: physical groups or clusters. A product of human imagination. See also that cloud looks like a bunny.

23 The history of constellations Most ancient peoples had a system. They were not the same. Ours came down from the greeks, who got it from the sumerians and babylonians. The International Astronomical Union recognizes 88 official constellations.

25 Chinese star chart

26 Thought Question The brightest stars in a constellation A) all belong to the same star cluster B) all lie at about the same distance from the Earth C) may actually be quite far away from each other

27 Thought Question The brightest stars in a constellation A) all belong to the same star cluster B) all lie at about the same distance from the Earth C) may actually be quite far away from each other

28 The Celestial Sphere Zenith When we look out at the night sky, it appears we are sitting in a large sphere. The moon and stars all seem to be fixed on this (imaginary) celestial sphere

29 The Celestial Sphere The 3D Universe becomes two dimensional due to our perspective on Earth. The north and south pole of the Earth extend out to the north and south celestial poles The equator of the Earth extends out to the celestial equator

30 The Celestial Sphere The 3D Universe becomes two dimensional due to our perspective on Earth. The north and south pole of the Earth extend out to the north and south celestial poles The equator of the Earth extends out to the celestial equator

31 The North Star Nothing special, just where the celestial north pole happens to point. Not the brightest star in the sky. Will not always be the north star: tune in next week to find out why.

32 Why do the stars move? The Earth Rotates (from W to E) It appears to us as if the sky (the Celestial Sphere) rotates (from E to W) Path of Stars Stars attached to celestial sphere Path is a circle (like latitude circle) Called diurnal circle (diurnal = daily)

33 Time of Day Meridian: circle halfway between east and west Stars, etc. are highest when they Transit the meridian Time of day = solar position w.r.t transit (Noon) am = ante meridian pm = post meridian 11 am 1 pm 10 am 2 pm Meridian (6am) E S W (6pm)

34 Rise / Set / Transit Rise - move above horizon (appear) Set - move below horizon (disappear) Objects rise in the east and set in the west Transit - moving past highest point in path E S W

35 Circumpolar Some stars never rise or set These stars are circumpolar

36 Circumpolar Some stars never rise or set Polaris, The North Star These stars are circumpolar

37

38 Why do the stars and Constellations you see depend on your latitude?

39 How to Locate Objects in the Sky Find NS / EW. Objects are located by altitude above the horizon and direction along the horizon (e.g., NW)

40 Get out your workbooks Divide up into groups of 2-3 people. Go through the Positions exercise on page#1.

41 Review Question How much of the celestial sphere can an Earth observer see at one time? A) less than half B) exactly half C) more than half

42 Review Question How much of the celestial sphere can an Earth observer see at one time? A) less than half B) exactly half C) more than half

43 Review Question Imagine you are standing at the North Pole. Of the stars that you can see, roughly how many of these stars are circumpolar? A) none B) less than half C) more than half D) all

44 Review Question Imagine you are standing at the North Pole. Of the stars that you can see, roughly how many of these stars are circumpolar? A) none B) less than half C) more than half D) all

45 Review of Small Angles Full circle = 360 degrees 1 degree = 60 arcminutes 1 arcminute = 60 arcseconds

46 How many arcseconds in 1 degree? 60 arcsec/arcmin x 60 arcmin/degree = 3600

47 Angular size of the Moon is 0.5 degree

48 Some Other Useful Angular Sizes Sun = 0.5 degree = 30 arcminutes Moon = 0.5 degree = 30 arcminutes Resolution of your eye = 1 arcminute

49 How big is an object in the sky? Can you use inches or miles to estimate the size of the moon by looking at it? Angular size depends on distance. If you don t know the distance to an object, you can t know the true size. If you don t know the true size, you can t know the distance to it.

50 How can the Sun and Moon have the same angular size (30 )? A)The Sun and the Moon are the same size B)The Sun is much larger than the moon, but is also much farther away

51 How can the Sun and Moon have the same angular size (30 )? A)The Sun and the Moon are the same size B)The Sun is much larger than the moon, but is also much farther away

52 Recap We assign objects positions on the celestial sphere, which stars appear to be fixed to. Our position on earth determines the constellations we see, and when we see them. Stars, the sun, the moon, and all the objects in the sky rise and set due to the rotation of the earth. Sizes of objects on the sky are measured as angles, not distances.
