Telescopes From the Ground Up

Telescopes From the Ground Up is an online exploration that traces the 400 years of telescope development from Galileo's refractor to NASA's Great Observatories. It also highlights the technology necessary for telescope development over time. The milestones of telescope development are presented in 10 sections called "eras." Associated "telescope pages" support each era by providing details about the invention and design of key telescopes. Biography pages that offer a glimpse of the inventors and astronomers behind the telescopes are included as well.

Challenge students to answer two big questions about light. Image Credit: NASA

Two lesson plans, with four activities each, challenge students to answer two big questions: "What is the relationship between light and exploration? " and "How is light used to explore the universe?" A student workbook supports the lessons in this guide.

Hubble Space Telescope's Top Science Findings

The words "Hubble Space Telescope's Top Science Findings" and an image of Hubble against a starry background

Astronomers and astrophysicists using Hubble data have published more than 4,000 scientific papers, on topics from the solar system to the very distant universe. Image Credit:STScI

Hubble counts among its achievements the discovery that an invisible force called "dark energy" pervades the universe; the revelation that "monster" black holes reside in the centers of many galaxies; and the discovery of the building blocks of today’s large, majestic galaxies. Read about Hubble’s top science findings and see the related pictures in this Star Witness news story.

Register online to investigate telescopes with your students. Image Credit: NASA

Register online for a free interactive videoconference to investigate telescopes with your students! Explore the history of telescopes from the early Galilean refractor to the future generation of NASA's space-based telescopes, with a special focus on the Hubble Space Telescope. Students will be guided along a timeline of astronomical history to understand how improvements to the basic telescope design allowed for greater and more distant exploration opportunities. Included in this event is an investigation activity about the Hubble Space Telescope in which students will apply math concepts such as estimation and multiplication. The event concludes with an exciting look at the future of NASA's space-based telescope missions.
