In this interactive laboratory, you'll investigate for yourself how fast several galaxies are moving. Galaxies are so large, and so far away, that you could never see them move just by looking -- even if you looked for a whole lifetime through the most powerful telescope! Fortunately, there is a way to detect the motion of a galaxy: By examining the spectrum of light from a galaxy, you can determine ... Full description.

This online Flash game is hosted on the James Webb Space Telescope Web site. Because the Webb Telescope is unusual in appearance, it doesn't look like a telescope - but it actually does have a lot in common with simple tube-shaped telescopes. "Scope It Out!" includes an introduction to reflecting and refracting telescopes and four levels of matching games, where you compare a simple reflecting telescope ... Full description.

Three Lessons - A Dusty Dilemma, Speaking Volumes About Dust, and The White Glove Test - are intended to familiarize students with the Student Dust Counter, data collection, and analysis. Accompanying the lessons is a Flash-based data viewer. Full description.

This product uses a collection of Hubble Space Telescope (HST) images of galaxies in the Coma Cluster, and engages students in an inquiry-based learning activity studying the evolution of galaxies in dense clustered environments. Students learn the basics of galaxy classification by making use of the HST images to discover a "morphology-density effect," and will then make hypotheses about the cause ... Full description.

This Hubble Space Telescope image shows what appears to be a delicate bubble of gas floating in space. In actuality, the bubble is the visible remnant of a powerful supernova explosion called SNR 0509. The bubble was formed from gas being swept up by the expanding shock wave. The accompanying activity is a curriculum support tool designed for use as an introductory inquiry activity. In the activity, ... Full description.

This Hubble Space Telescope images shows a group of interacting galaxies called Arp 273. The accompanying classroom activity is a curriculum support tool designed for use as an introductory inquiry activity. During the classroom activity, students use the images and text on the lithograph to generate questions about galaxy interactions. They will conduct research to answer their questions, and create ...
