Galaxy Zoo Worksheet
For this activity, you will be classifying and examining images of galaxies that were captured by
the Sloan Digital Sky Survey (SDSS).
Navigate to the
Galaxy Zoo website
, and click on the yellow
Begin Classifying
button. You will be
presented with an image and begin answering a short series of questions aimed at helping you
characterize the galaxy in the center of the image. After answering all of the questions, you’ll
immediately be presented with a new image.
Note:
You will be asked if you’d like to discuss the
image before moving on to the next one. If you have an account with Galaxy Zoo, you can use
this feature, but it is not required.
Your task is to
find five unique galaxies
and classify them below. Make sure your written
content is well-developed, proof-read, and polished. Also make sure it is free from spelling and
grammatical errors. For each galaxy, you will:
1.
Include a screen shot from Galaxy Zoo (see
Inserting Images Into a Worksheet
for help
with this).
2.
Identify the galaxy type (Elliptical, Spiral, Peculiar, Irregular).
3.
Briefly describe any distinguishing features in the galaxy (bars, jets, ring, etc.)
4.
Make one prediction or conclusion about the galaxy’s age, formation, or evolution based
on the image.
After characterizing each of the five galaxies you’ve chosen, you will answer two “Big Questions”
that will require you to think about the structure and location of these galaxies.
