This is an activity about how the Sun can affect the Earth's atmosphere, specifically the ionosphere. Learners will use real data from a Sudden Ionosphere Disturbance Monitor, or SID Monitor, to identify the signatures in the graphed data that can... (View More)

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)

The Hubble Ultra Deep Field lithograph shows the deepest visible light observation of the early universe. In vibrant contrast to the image's rich harvest of classic spiral and elliptical galaxies, there is a zoo of oddball galaxies littering the... (View More)

This image from the Hubble Space Telescope shows light from hot stars eating away the surface of the dust and gas cloud in this region of the Eagle Nebula to reveal a pillar composed of denser material. The text includes information about the... (View More)

Learners will interpret spectral graphs to determine the atmospheric composition of Earth, Venus, and Mars, and then mathematically compare the amount of the greenhouse gas, CO2, on these planets. Students will brainstorm what things, along with... (View More)

This is an online lesson associated with activities during Solar Week, a twice-yearly event in March and October during which classrooms are able to interact with scientists studying the Sun. This activity is scheduled to occur during Monday of... (View More)

Gamma-ray bursts are distant explosions that briefly outshine the rest of the gamma-ray universe. In this lesson, students will follow the same procedures used by today's astronomers to determine two basic facts about gamma-ray bursts: their... (View More)

This Hubble Space Telescope image captures the chaotic activity on a three-light-year-tall pillar of gas and dust reminiscent of a craggy fantasy mountaintop surrounded by wispy clouds. New stars buried inside the pillar cannot be seen in this image... (View More)
