Checklist:

Refer to the Instructions for Phase 1, Phase 2, and Phase 3 for more-complete descriptions of all of the required items for your “journal.”

Your file submission in this assignment must be a single PDF file — a document containing a series of 3 images, each with accompanying written sections as follows:

Image 1

Created according to the Instructions for Phase 1.

Writing to accompany Image 1

You should include answers to the following questions, about this first image:

Which object did you choose to work with?

(from the list of five potential astronomical objects)

In just a couple of sentences, briefly describe what differences you can see between how the object looks across the three separate images included.

(Suggestions: You might look for such things as stars or other small features that are extra-bright in one wavelength and dimmer in others, or clouds of gas or dust that are overall brighter in one image than another. Your description can be very general, focusing on appearances only and not concerned with scientific interpretation of why there are those differences; that’s in the next question.)

Again, in just a couple of sentences, briefly consider the reason for visible differences between one wavelength image’s contents versus another’s.

(Hints: Recall previous lessons on the relationship between temperature and color, of stars’ ages, and — if applicable — of where in galaxies certain kinds of stars are more likely to be found.)

Image 2

Created according to the Instructions for Phase 2.

Writing to accompany Image 2

You should include answers to the following questions, about this second image:

Why did you make your choices for hue/saturation/lightness for your second image?

Are any particular details more or less visible in your Image 2 than in Image 1?

Image 3

Written Statement for Image 3

This should be at least 200 words for full credit. It should describe your original composition, the component images, colors, and your overall theme:

Identify the individual images used in your overall composition. What theme ties them together?Explain

Describe why you chose the specific colors assigned to each image layer. How do they look, together?
