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)

Audience: Informal education

This is a lithograph about a scientific observation by the Reuven Ramaty High Energy Solar Spectroscopic Imager, or RHESSI, spacecraft. Learners will read about a chance observation of a gamma-ray burst in 2002 that has shed new light on the... (View More)

This 2-page color fact sheet briefly describes NASA's Kepler mission, its instruments, and ground system. Also included are tables listing the instrument parameters and the major institutions involved. Kepler is a spaceborne telescope specifically... (View More)

In this interactive, online activity students elect a simple random sample to draw conclusions from data as presented in the Hubble Deep Field-North and Hubble Deep Field-South images. The optimal sample size is determined by exploring sample... (View More)

Audience: High school

This interactive, online activity introduces the idea that everything emits electromagnetic radiation, including students. Students discover how the light emitted from an object (a robot) changes as the object is heated. A graph shows the amount of... (View More)

In this assessment activity, students generate a data sample from either the Hubble Deep Field-North or Hubble Deep Field-South images, and compare the sample to data from the unselected field. This provides students with a real-life example of how... (View More)

Audience: High school

In this activity, students determine the direction to a gamma ray burst using the times it is detected by three different spacecraft located somewhere in the solar system. We assume that all the spacecraft are in the plane of the Earth's orbit... (View More)

In this activity, students look at the distribution of aluminum foil balls arranged in a circle on the floor, and compare them to the distribution of gamma-ray bursts on the sky. This activity is part of a unit designed to use gamma-ray bursts -... (View More)

In this hands-on activity, students analyze the data on Mystery Object Cards, observe that astronomical objects have many observable properties, and discover that these properties allow scientists to categorize astronomical objects into different... (View More)
