Go to the websites found below to answer the questions listed.

Turn in your answers to the substitute at the end of the period.

1) How long would it take a car to get to the moon? (assuming it actually could!)

2) How long would it take for a 757 jet to get to the moon? (assuming it actually could!)

3) The voyager spacecraft is one of the fastest spacecrafts launched to date. How long would it take the Voyager spacecraft to get from Earth to the moon?

4) How long would it take Voyager to get to Proxima Centauri?

5) Explain why interstellar space travel is out of reach for us with current rocket propulsion technology.

6) Sketch what the big dipper will look like in 100,000 years.

7) What will the Belt of Orion look like in 500,000 years? (sketch it!)

8) When comparing the same size collector at different distances from a source emitting particles, what pattern is seen? (Click "run", then after 20 -30 seconds, click stop. Then click "plot")

9) Why is it that we can see the dark line spectrum from the sun?

10) What are the characteristics of an "M" class star?

11) What is the likely classification of the Sun? (HINT: Pay attention to the temperature and color)

12) What are the first signs of a star's old age?

13) There are how many recognized constellations (original)?

14) What does the constellation delphinus represent?

15) Compare the absolute brightness of Sirius with its apparent magnitude. Is it further away than 32.6 light years, or closer than 32.6 light years? (THIS lets me know whether you understand the difference between the two magnitudes, and whether you understand the concept of absolute magnitude!)

16) Write the Greek alphabet letter which represents Sirius.

17) List the 7th brightest star... (both apparent and absolute...)

18) How did Hubble classify galaxies?

19) What are the 3 major types of galaxies, by Hubble's classification scheme?

20) What are irregular galaxies?

Happy Groundhog day!!!

Punxsutawney


By going to the web sites below you should be able to find the answers to questions on your study guide that may be difficult to find.

1) Diagram and label a comet's structure and explain why the tail always points away from the sun.

2) Diagram and label a lunar eclipse and a solar eclipse.

3) Diagram and label the moons internal structure

4) What is a Blue Moon?

5) How did Fred Whipple describe a comet?

6) What causes the moons phases?

Go to this web site and discover the parts of a comet. Make sure you change the different variables while you are on the site. It will help explain a lot of things about the orbits of both planets and comets.

Comet info and animations


This web site has a very nice diagram and great information about comets. It doesn't mention Whipple, but it does have the desciption which he gave them!

Comet Introduction


This is a very interesting site - it has animations of the different areas of the Solar System, and includes the very outermost part of the Solar System. Make sure you do the close-ups.

Inner, Middle, and outer Solar System information and animations



Make sure you toggle on the buttons to change your perspective of the Solar System.

Solar System animations



On this web site find animations of various things having to do with astronomy. Hopefully this will work, but I haven't checked out the web site on the computer lab machines. IF it works, make sure you check out "The Phases of the Moon" and "Where will the moon be tomorrow".

Movies for Astronomy



This animation of actual photo's of Jupiter and its moons shows motion over time.
7) How long would it take to see the motion shown in the animation?

Jupiter Moon Animation



If you're STILL looking for Fred Whipple's stuff to answer your study guide...

About Fred Whipple....



Lots of Links....


At this web site you can find information about the moons structure.

Moon structure....



Eclipse information....



Lunar eclipse photo gallery....



Shadow and Substance eclipse animation....



Lunar eclipse animation....



Why eclipses happen....



Solar eclipse information....



Solar eclipse animation....



IU Astronomy Dept. movies and animations....



Make sure you start and stop this animation at its various phases. It shows you what an observer on Earth would see and the relationship between the Sun-Earth-Moon system.

Lunar phase animation....



Lunation....



Lunar Phase animation....



What is a blue moon???



Blue moon mistake?



Blue moon..Really!!!
