Telescopes From the Ground Up
This online exploration traces the history of the telescope from Galileo's first look at the stars to the work of modern observatories. Milestones in telescope development are highlighted along with biography pages, which provide a glimpse of the inventors and astronomers behind the telescopes. The science of light and telescopes is presented in a section called "Get to the Root of It."
This online exploration pits the student against a computer virus that has scrambled the Hubble Space Telescope's Servicing Mission 3B. Using critical thinking and reading skills to search for word and picture clues, students become the "Mission Mastermind" to reorganize the sequence of events of Servicing Mission 3B into the correct order.
The Hubble Space Telescope Lithograph
This image of the Hubble Space Telescope was taken just after the observatory was released from space shuttle Atlantis near the end of Servicing Mission 4 in 2009. Text describes how the telescope works. A diagram identifies the telescope's science instruments and other important parts. An inquiry-based classroom activity is included.
Eagle Nebula (M16) (2014) Lithograph
These Hubble Space Telescope images show two views of the iconic pillars in the Eagle Nebula — one in visible light and the other in near-infrared light. Near-infrared-light penetrates the dust and gas to reveal a myriad of stars behind the nebula, as well as newly forming stars within the pillars. An inquiry-based classroom activity is included.
Star Cluster Westerlund 2 Lithograph
This Hubble Space Telescope image shows the nebula in which the star cluster Westerlund 2 was born. Hubble captured an image of this compact star cluster before the stars had time to migrate away from each other, as open clusters tend to do.
