Presentation Transcript

  1. Active Astronomy:Learning about Infrared Light Doris Daou SIRTF / JPL EPO Dana Backman SOFIA / NASA-Ames EPO

  2. Outline • Electromagnetic radiation ( = light! ) • Infrared radiation - Infrared camera demos • Infrared astronomy • NASA’s SIRTF and SOFIA projects • [break] • Active Astronomy kits • Contact info

  3. Temperature determines dominant wavelength emitted …

  4. Getting the WHOLE picture • An object can look radically different depending on the type of light collected from it: Constellation Orionleft: visual wavelengthsright: far-infrared image

  5. Visible: dark nebula, heavily obscured by interstellar dust • Near-IR: dust is transparent, embedded proto-stars can be observed • Mid- and far-IR: glow from cold dust is directly observable Visible Near Infrared Mid-Infrared

  6. Infrared gives us the first glimpse of star formation on a spectacular scale.

  7. SIRTF - Space Infrared Telescope Facility

  8. SOFIA -- The Next Generation Airborne Observatory • 2.5 meter telescope mounted in a 747-SP • “First Light” expected winter 2004-2005 • 150 flights per year when fully operational • First observatory designed to support E/PO

  9. Airborne Astronomy Ambassadors • Educators will fly onboard SOFIA to experience and participate in the scientific research experience • E/PO work station • 10 seats in front cabin • Access throughout the observatory • 200+ visitors fly each year in full operation

  10. Register online & receive SOFIA’s EPO Electronic Newsletter http://sofia.arc.nasa.gov/Edu/newsletter/subscribe.html

  11. Active Astronomy kits • Available ready-made through the Astronomical Society of the Pacific’s online store • http://www.astrosociety.org ($70 each for ready-made kits; approx. $60 if you want to hunt down the pieces yourself) 1) Light filters (gels) 2) Detecting infrared radiation 3) Infrared radiation and reflection 4) Infrared radiation used to transmit information

  12. The Herschel Experiment • SIRTF has produced a self-contained, classroom-ready activity that recreates Herschel’s 1800 discovery of infrared light. • Evaluated by Origins Forum, mapped to national education standards • Activity has become a popular science-fair project • Selected as OSS Outstanding Resource

  13. Visit our website at coolcosmos.ipac.caltech.edu • Also in Spanish • Request videos and posters from: Michelle Thaller thaller@ipac.caltech.edu (626) 395-8670

  14. For further information: • SIRTF Web sitehttp://sirtf.caltech.edu • SIRTF’s award-winning IR tutorial http://coolcosmos.ipac.caltech.edu • SETI Institutehttp://www.seti.org • Astronomical Society of the Pacifichttp://www.astrosociety.org • can purchase infrared demo kits at their on-line store
