Nebula astronomy is a stand-alone radiation astronomy lecture and an article studying astronomical radiating sources, or natural radiating sources called nebulas.

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

To improve your score, read and study the lecture, the links contained within, listed under See also, External links, 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.

Suggestion: 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!

Quiz[edit]







  

1

Yes or No, A cloud in outer space consisting of gas or dust is called a nebula.

Yes
No

2

True or False, Any small luminous green dot appearing in the cloudless portion of the night sky, especially with a fixed location relative to other such dots is most likely to be an active galactic nucleus.

TRUE
FALSE

3

Evidence that demonstrates that a model or idea versus a control group is feasible with respect to radiation sources is called a

.

4

Yes or No, Hubble astronomers have found an unexpected surprise while surveying more than 100 planetary nebulae in the central bulge of our Milky Way galaxy. Those nebulae that are butterfly-shaped or hourglass-shaped tend to be mysteriously aligned such that their rotation axis is perpendicular to the plane of our galaxy.

Yes
No

5

True or False, A dominant group with respect to radiation astronomy sources differs from a control group in that it rules the treatment of the control group.

TRUE
FALSE

6

Complete the text:

A short or

realization of a certain

or idea to

a treament's feasibility with respect to radiation astronomy sources is called a proof of

.

7

True or False, A control group may be used in respect to radiation astronomy sources to demonstrate no effect or a standard effect versus a novel effort applied to a treatment group.

TRUE
FALSE

8

True or False, Pure radiation sources involve no doing apart from themselves.

TRUE
FALSE

9

Complete the text:

A proof-of-concept structure, including a control group, consists of

, procedures, findings, and

10

True or False, The purpose of a treatment group with respect to radiation astronomy sources is to describe natural processes or phenomena for the first time relative to a control group.

TRUE
FALSE

11

Yes or No, Planetary nebulae are the expanding gaseous shrouds encircling dying stars.

Yes
No
