This manual provides simple demonstrations to show how lenses and mirrors are used to create telescopes. It was created for use by the Night Sky Network of astronomy clubs.
This poster series highlights six astronomical images observed with NASA's Great Observatories (Hubble, Chandra and Spitzer) and found within the "From Earth to the Universe" (FETTU) exhibition. Each poster contains additional information on the... (View More) historical context of the astronomical objects (constellation, view with the unaided eye), as well as basic facts about the specific object, the category of object, the NASA missions used, and the contributions to advancing knowledge of the universe enabled by the NASA observations. The materials expand on the theme of demonstrating how far understanding and knowledge have come since Galileo's telescope 400 years ago with illustrations of specific NASA contributions, provide background information on which informal educators can draw for NASA-related activities in their programming, and include student activities.

This 5-minute animation portrays fluctuations in the cryosphere through observations collected from a variety of satellite-based sensors. The cryosphere consists of those parts of the Earth's surface where water is found in solid form, including... (View More) areas of snow, sea ice, glaciers, permafrost, ice sheets, and icebergs. In these regions, surface temperatures remain below freezing for a portion of each year. (View Less)
This Hubble Space Telescope image of galaxies appears to form the number 10. The text describes the image and provides a brief explanation of why astronomer Halton Arp compiled his catalogue of odd-looking galaxies in the 1960s. In the accompanying... (View More) educational activity, In Search of ... Peculiar Galaxies, students investigate galaxy interactions through a level 1 inquiry activity using the images and text from the lithograph and other resources. A level 1 inquiry activity can help prepare students to become independent thinkers. (View Less)
This paper model of the Fermi Gamma-ray Space Telescope includes three pages of parts that can be cut out and assembled using common household items. It also provides a short description of the scientific instruments on board Fermi, as well as links... (View More) to other resources about its instruments. (View Less)
This 24 minute planetarium show teaches about meteors, meteorites, asteroids, and comets. The show was created for fulldome theaters, but is also available on DVD to be shown in flat version for TVs and computer monitors, and can be freely viewed... (View More) online. It shows the effects of the Chixulub and Tungusta events, plus the Pallasite impact that resulted in the Brenham meteorite fall, and describes ways that asteroid hunters seek new objects in the solar system, and how ground penetrating radar is used to find meteorites that have survived to the Earth's surface. Narrated by astronaut Tom Jones, it also discusses ways that humans might try to deflect an asteroid or comet that is on a collision course with Earth. The show was created for informal science venues (digital planetariums); it is also useful as supplemental material for middle school science. Impact Earth is available for free if presented directly from the Space Update site (widescreen or fisheye views linked from YouTube). Otherwise, a DVD of the show can be purchased for $10.

This resource shows how generations of explorers have taken us, step by step, further into the expanse of the universe. Using photographs and text, this resource takes readers out of our solar system, into the realm of the stars, the galaxies, and... (View More) finally the vast panorama of the observable universe.

The main scientific instrument on the Gamma-ray Large Area Space Telescope (GLAST) is the Large Area Telescope (LAT). This interactive computer-based educational activity allows students and web users to see the results when gamma-ray photons of... (View More) different energies and incident angles hit the LAT. The photons convert into electron-positron pairs which travel through 19 interleaved layers of silicon into the cesium-iodide calorimeter. Background information about the mission and the LAT is also provided. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi. (View Less)
This is a story about space exploration. Learners will read about missions to asteroids and comets, consider the measurements and math required for the robotic spacecraft to visit these objects, and are invited to finish the story themselves. The... (View More) provided extension explains how to use a K-W-L chart with the story and provides a glossary of terms. (View Less)
This is an online crossword about the Big Keck telescope. Learners can complete the crossword and read text about how the telescope works.
