Question: How long has light traveled from the most distant galaxy we have observed?

1. 200 years
   
2. 20,000 years
   
3. 20,000,000 years
   
4. 20,000,000,000 years
   

Incorrect Answer

Correct Answer
A galaxy has recently been observed with a red-shift of 4.9. That means that the light we observe today has a wavelength 4.9 times its original wavelength. This is a result of the expansion of the universe. The exact distance to which this corresponds depends on details of the universe that we do not yet know. However, the distance is probably within a factor of 2 or 3 of 20,000,000,000 light years.

1. Between the orbits of Mars and Jupiter
   
2. Between the orbits of Venus and Earth
   
3. Between the orbits of Earth and Mars
   
4. Between the orbits of Pluto and Saturn
   

Incorrect Answer

Correct Answer
The so-called "Asteroid Belt" lies between the orbits of Jupiter and Mars. Most of the known asteroids, including most of the large asteroids are found in this region of the Solar System.

Question: Approximately how many stars does the Andromeda Nebula contain?

1. 100
   
2. 100,000
   
3. 100,000,000
   
4. 100,000,000,000
   

Incorrect Answer

Correct Answer
The Andromeda Nebula (Galaxy) is often considered a twin of the Milky Way although it is a little larger. From the speed at which a star near the edge circles the center, we estimate that its mass is equal to that of 100,000,000,000 to 1,000,000,000,000 stars like the sun.

Question: If you could travel in a space ship at the speed of light away from the solar system, how long could you see the sun?

1. 3 years
   
2. 30 years
   
3. 300 years
   
4. 3000 years
   

Incorrect Answer

Correct Answer
The exact answer depends on your eyesight and observing conditions but most people could see the sun for about 30 years in reasonably good observing conditions. The sun is considered an average star. There are stars as much as 400,000 brighter than the sun and others as much as 400,000 time fainter if they could all be seen at the same distance.

Question: How far have spacecraft from Earth traveled into space?

1. Well over 10 Light-years
   
2. Well over 1 Light-years
   
3. Somewhat less than one Light-day
   
4. A bit less than one Light-year
   

Incorrect Answer

Correct Answer
The planetary exploration missions Pioneer and Voyager have barely traveled beyond our Solar System. These are the fastest spacecraft ever launched from Earth. Even these spacecraft will take a very long time to travel one light-year. We don't have the knowledge or technology to send space probes or manned craft to even the nearest stars!
