  • variable star
  • white dwarf
  • zodiac

  • 2. Write down any additional defintions for terms that you do not know.


    The Constellations

    Next, you will visit National Geographic's Star Journey page. Using this website, you must select a constellation from the Northern Hemisphere and a constellation from the Southern Hemisphere.

    1. To select a constellation for the Northern Hemisphere, click on a section of the grid on the left hand side of the sky map.
    2. Choose a constellation (click a different section if you don't see one that you like) and record the name of it on your paper.
    3. To select a constellation for the Southern Hemisphere, click on a section of the grid on the right hand side of the sky map.
    4. Choose a constellation (click a different section if you don't see one that you like) and record the name of it on your paper.

    You must provide the following information about each of your constellations:
    You can use the following websites to find the above information:

    Hawaiian Astronomical Society- Click on the link labeled Constellations Listing and then click on a letter to link to an alphabetized link of constellations. If you click on the name of your constellation, you will be connected to a page of information about your constellation.

    Munich Astro Archiv Constellation Pages- Click on the link 88 constellations to link to an alphabetized list of the constellations. Click on the abbreviation for your constellation to view a page of information about your constellation. From this page, you can click on the link labeled Stellar Data to find additional information.


    In addition, using the Munich Astro Archiv Constellation Pages, click on the link labeled asterism and identify and describe the following things about one asterism. Note: You cannot describe the Big and Little Dippers


    Mythology of the Constellations

    Now it's time to explore a little bit of the mythology behind the names of the constellations. You can use the following two sites to find information about the 'myth' connected to each of your constellations. Some constellations do not have a true myth associated with their names, however, you should be able to find some story or significant meaning to the name.

    Bullfinch's Mythology- Click on the link SEARCH the Age of Fable to locate any references to your constellation name.

    If you can't find information using Bullfinch's, try using the Hawaiian Astronomical Society. Once again, click on the link labeled Constellations Listing, click on a letter to link to an alphabetized list, and then click on the name of your constellation.

    In your own words, write a brief summary of the myth or story of each of your constellations.

    The Stars at Night

    Next, you will become a little bit more familiar with where in the sky your constellations are located.

    1. Make a list of the constellations that surround each of your constellations. Use the following websites to locate the constellations:

    National Geographic Star Journey- Click on a section of the grid for an enlarged view of your constellation. Click surrounding sections if necessary.

    Stars and Constellations- Click on the link labeled Interactive Sky Charts to get an alphabetized list of the constellations. Click on the name of your constellation to view a map of your constellation and its surroundings.

    2. Find and record the months of the year that your constellations are visible in the sky. Follow the steps below:
    1. Visit StarGazer and click on the button labeled Open StarGazer Window.
    2. Change the date to January 15th by clicking on the number for the month (it will become highlighted), and then use the up/down arrows to change the month. Do the same thing to change the day.
    3. Change the time to 10:00 pm by clicking on the hour and using the up/down arrow to change the number. Do the same thing for the minutes and the am/pm.
    4. Change the latitude to your latitude by clicking on the value for the latitude and using the up/down arrows to change the latitude.
    5. Advance the date, month by month, and record when your constellation is visible (try changing the time as well- maybe your constellation sets early, or rises late!).
    6. To locate your constellation in the Southern Hemisphere, click on View in the StarGazer window and select Latitude. Select a city from the Southern Hemisphere. Repeat Steps A-E for the southern constellation.


    Eyes on the Sky

    Now, take a look at the Skywatching Center-Tonight's Sky to find out what is happening in the sky tonight and in the upcoming week.


    Astronomy in the News

    Take a look at a couple of articles written about astronomy.

    1. First, visit Phil Plait's Bad Astronomy: Bitesize Astronomy.

    2. Second, check out Astronomy.com's site.


    Make a Constellation
    Finally, you will need to make your own constellation by following the directions listed below.

    1. On a piece of graph paper ( 5 mm X 5 mm ), number the X-axis from 0 to 30 and the Y-axis from 0 to 40.
    2. Plot the coordinates that are listed below. Make visible dots (.) to mark the points.
    ( 5, 35.5 )
    ( 6, 34 )
    ( 6, 23 )
    ( 6, 12.5 )
    ( 7, 11 )
    ( 7, 21 )
    ( 10, 14 )
    ( 11.5, 28 )
    ( 15, 7 )
    ( 15, 15 )
    ( 17, 12 )
    ( 17, 22 )
    ( 17, 30 )
    ( 19.5, 27.5 )
    ( 21, 20 )
    ( 23, 27 )
    ( 25.5, 30 )
    ( 28.5, 32 )
    ( 29.5, 36.5 )
    1. Use all or some of the "stars" that you have plotted to make your own constellation. You may rotate the page in any direction. Connect the stars that form your constellation. Then draw an outline of the shape of your constellation.
    2. Give your constellation a name.
    3. Write a myth about your constellation. The myth can take place in any time period- from ancient times to modern times (or even the future!).
