In this segment, Nathan Tehrani talks about the electromagnetic spectrum and how space telescopes tell us more about the early history of our universe, how stars form, and more. This includes a demonstration of IR light using a remote control, the history of Hubble including its repair, Chandra the X-ray telescope, Spitzer the IR telescope, and how composite images from all three are created.

Josh shares images of the Moon and an activity where students infer the color of post-it notes based on what they see in red, green, and blue filters (activity sheet). Learn about how scientists combined images of the Moon (visible, IR, radio, x-ray) with rocks collected by the Apollo astronauts to understand more about the composition and formation of the Moon.

Learn about spectroscopy with Evan! Using a collection of gases tubes, a generator, and a diffraction grating, we can learn about the composition of our atmosphere and of distant stars. Excellent way to learn a bit of chemistry, physics, and astronomy.

Ellie shares a WV SPOT presentation, The Invisible Universe 2.0. From the earliest telescopes to the Green Bank Telescope, learn about how this technology has helped us to learn more about the universe and our place in it. Learn about (and hear!) pulsars, special stars that astronomers (and high schoolers!) use to learn more about the universe.

Join a class from East Fairmont Middle School as Luci helps them collect data with the 20m radio telescope at Green Bank Observatory. Learn about how radio telescopes work, why the telescopes at Green Bank were built where they were, how pulsars are formed, and why they are important. See how scientists use the 20m telescope to collect data in real time!
