In this activity, students use Newton's Laws of Motion, and the motions of the planets, to determine the mass of the sun. They then use the same techniques to determine the mass of a galaxy. In doing so, students convert among different units of... (View More)

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. This activity includes a student... (View More)

In this activity, students describe the characteristics of different types of galaxies (spiral, elliptical, barred spiral, peculiar, or irregular) in their own words. They also classify galaxies seen in the Hubble Deep Field. This activity includes... (View More)

In this activity, students will use a simulator of an orbiting X-ray observatory to observe a supernova remnant, the expanding gas from an exploded star. They will take X-ray spectral data, analyze them, and answer questions based on that data. This... (View More)

In this activity, students explore the idea of classifying objects. They start by giving examples of objects that can be classified in everyday life and in science. They then characterize and classify a set of galaxies using their own scheme, and... (View More)

In this activity, students will interpret and analyze the information presented on the Evidence for Hidden Mass graph. They will observe trends in the graphs, and use it to determine if there is evidence for hidden mass. This is Activity 6b in the... (View More)

How big and how old is the universe? This culminating telescope investigation for high school students has them first taking images of galaxies near and far; then measuring and calculating their distances; then predicting how they might expect... (View More)

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)

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)

The Gamma-ray Burst Skymap website automatically updates for each gamma-ray burst as it occurs, whether detected by Swift or other orbiting satellites. For each burst, the location on the sky, star map, constellation and detecting mission are... (View More)
