These guides showcase education and public outreach resources from across more than 20 NASA astrophysics missions and programs. The twelve guides - one for each month - contain a science topic, an interpretive story, a sky object to view with... (View More) finding charts, hands-on activities, and connections to NASA science. The guides are modular, so that educators can use the portions that are the most useful for their audiences/events. Following is the theme for each month: January - Betelgeuse, February - Orion Nebula, March - Pleiades, April - Pollux; May - Hubble Deep Field, June - Hercules Cluster, July - Ring Nebula & Veil Nebula, August - The Search for Habitable Worlds, September - Milky Way Galaxy, October - Upsilon Andromedae, November - Andromeda Galaxy, and December - Crab Nebula.

In this hands-on activity, students learn about the different realms of the Universe and explore their sizes and relative scales. They will be guided through a process that uncovers the immense sizes of the Sun, Solar System, Solar Neighborhood,... (View More) Milky Way, Local Group, Supercluster, and the observable Universe. The full version of this activity involves students doing simple math computations, however it can also be done without the math. There are some inexpensive materials involved, as well as a powerpoint presentation. It is intended for grades 8-12, but can be adapted down for lower grade levels. (View Less)

This lesson provides a way for students to determine the relationship between the distance from a light source and its brightness. Once students discover the relationship, they can begin to understand how astronomers use this knowledge to determine... (View More) the distances to stars and far away galaxies. (View Less)

In this activity, students compare two images of the Crab Nebula taken more than 40 years apart. By measuring the motion of some of the knots of glowing gas in the neubla, students will be able to determine the date of the supernova explosion that... (View More) set the Crab Nebula into motion. This is Activity 2 of the "Supernova Educator's Guide" developed by the XMM-Newton and GLAST E/PO programs. The guide features background information, assessment rubrics, student worksheets, extension and transfer activities, and alignment to national education standards. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi. (View Less)

In this activity, students examine the first line of evidence, galactic motion, for the notion of an expanding universe. By examining the spectrum of light from a galaxy, students can determine whether a galaxy is moving toward or away from us, and... (View More) how fast. Students will look at optical images of four galaxies, compare the emission spectra from these same four galaxies, and measure the wavelength of the red hydrogen line for each galaxy. This activity is part of the "Cosmic Questions" educator's guide developed to support the Cosmic Questions exhibit. This activity can be used in conjunction with, or independently of, the exhibit.

In this activity, students use rulers to measure distances between hypothetical galaxies and then use these distances to calculate the velocities of the galaxies. This activity is part of the "Cosmic Questions" educator's guide that was developed to... (View More) support the Cosmic Questions exhibit. This activity can be in conjunction with, or independently of, the exhibit. (View Less)

Using real data from NASA's Fermi satellite, students determine the size and energy of an active galaxy flare region. This activity includes background information for teachers, student worksheets, procedures, adaptations, extensions, an assessment... (View More) rubric, and related resources. This is activity 3 of 3 in the "Active Galaxies Educator's Guide." (View Less)
