Object astronomy is a lecture and an article about a specific kind of astronomical entity.

You are free to take this quiz based on object astronomy at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, and in the astronomy resources template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

A suggestion is to have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!

O III green emission line
green continua
biconical structure
a common cone axis and apex
ionized gas
neon clouds

8. Complete the text:

"In the green, the of the pure composition qualitatively appears a better to the shape of the observed polarization curves."

9. True or False, The silicates used to model the cometary coma dust are olivene (Mg-rich is green) and the pyroxene, asbestos.

TRUE
FALSE

10. Which of the following is not a phenomenon associated with a comet?

airglow
elongated dust particles
high albedo
olivine
Rayleighs
coronal mass ejection

13. True or False, There are green or green mineral containing meteorites.

TRUE
FALSE

watery abyss
aphrodite
Hermeneutes
cold dark matter
Heracles
unseen mass
Silver age

15. Complete the text:

Condensed noble gases, most notably liquid and liquid , are excellent radiation detection .

16. True or False, The presence of a liquid may be detected by using S-waves.

TRUE
FALSE

17. Observations of Titan have benefitted greatly from what phenomenon?

a dense, opaque atmosphere
lightning
extensive meteorite cratering
a flattening out
liquid hydrocarbon lakes
the reflected light of allotropes and compounds of sulfur

18. Which of the following are radiation astronomy phenomena associated with the apparent liquid-object Earth?

rain
snow
hail
neutron emission
polar coronal holes
meteor emission
rotation

19. Why is much of the surface of Mars covered with red iron oxide dust when the rocks that compose much of its surface are blue or violet?

Mars has been systematically bombarded with small iron-nickel meteorites or micrometeorites that oxidize in its atmosphere
Mars has been frequently bombarded with hematite containing micrometeorites
asteroid impacts on Mars may have forced iron from near its core into the atmosphere and onto the surface as hematite dust that oxidized
Mars is like Earth in surface hematite composition, but Earth has much more water
precipitation from iron-rich water
