Follow the 400 year background story leading to the creation of the first 3D model of a supernova (Cassiopeia A). This article explains how science, mathematics and technology led to the visual representation of data gathered by NASA's Chandra X-ray Observatory.

## What Makes a World Habitable?

This is a lesson about the characteristics necessary for life. Learners will identify the top candidates for life in the solar system by examining Habitability Cards, which discuss each planet and the six large moons in terms of water temperature, atmosphere, energy, and nutrients.

## Identifying Unusual Galaxies

In this activity, students match unusual galaxies with their distinctive names and justify their reasoning. Students discover that often, galaxies acquire their names based upon how they appear to observers.

## Coloring the Universe (with Pencil Code)

Students participate in a series of activities to discover how astronomers use computers to create images and understand data.

## Back to the Future

Students will compare aerial photos of their area from the past with current photos, noting differences and then conducting ground truth investigations to determine what happened.

## Student Illustrations and Writing About the Sun

This is an activity used to identify students' initial ideas and potential scientific misconceptions about the Sun. Learners will draw and label the Sun and write a supplemental paragraph containing what they know about the Sun.

## Diameter of the Moon

Learners will calculate the diameter of the Moon using proportions. This activity is in Unit 1 of the Exploring the Moon teachers guide, which is designed for use especially, but not exclusively, with the Lunar Sample Disk program.

## Measuring Solar Rotation - Solar Latitude/Longitude Method

This is an activity about the period of the Sun's rotation. Learners will use image of the Sun from the SOHO spacecraft and a transparent latitude/ longitude grid called a Stonyhurst Disk to track the motion of sunspots in terms of degrees of longitude.

## Stratospheric Ozone and Ultraviolet Light

This is a lesson where learners explore how the creation and destruction of ozone protects us from ultraviolet radiation (UV).
