This slide set focuses on the the discovery of extensions of galactic disks made up of hot, young stars bright in ultraviolet light, made by the GALEX mission with follow-up by the Hubble Space Telescope. It is one of a series of short, topical... (View More)

Learners will use a spectrograph to gather data about light sources. Using the data they’ve collected, students are able to make comparisons between different light sources and make conjectures about the composition of a mystery light source. The... (View More)

This activity introduces students to the visible light spectrum, and demonstrates what happens to the appearance of an image when certain wavelengths of light are blocked by filters or made visible using special tools. Students are lead through... (View More)

In this activity, students explore images taken with telescopes sensitive to several different wavelengths of the electromagnetic spectrum. Students compare the images to determine that light carries information about physical features in the... (View More)

Learners will build an open spectrograph to calculate the angle the light is transmitted through a holographic diffraction grating. After finding the desired angles, the students will design their own spectrograph using the information learned. The... (View More)

Learners will look at various light sources (including glow sticks and Christmas lights) and make conjectures about their composition. The activity is part of Project Spectra, a science and engineering program for middle-high school students,... (View More)

This lesson uses a simple discrepant event to demonstrate the underlying cause for early miscalculation of the size of the Milky Way galaxy. By standardizing the Cepheid period-luminosity relationship without recognizing there were two types of... (View More)
