Exploring Space Weather: Understanding the Sun's Impact on Life on Earth

Join scientist Terry Kucera from NASA as he dives into the dynamics of solar activity and its effects on Earth in the interactive seminar "Living and Working in Space: Energy." Discover how solar phenomena such as coronal mass ejections (CMEs) influence space weather, magnetic fields, and even human activities. This engaging session includes polls and fascinating facts about the Sun, solar cycles, and the implications of solar energy on our planet. Perfect for educators and space enthusiasts alike!

  1. LIVE INTERACTIVE LEARNING @ YOUR DESKTOP NASA/NSTA Web Seminar: Living and Working in Space: Energy http://institute.nsta.org/web_seminars.asp

  2. Living and Working in Space: The Solar Cycle and Space Weather Terry Kucera Scientist with the STEREO and SOHO Missions NASA/GSFC • The Sun and Solar Activity • Magnetic Fields • Space Weather

  3. I heard Terry Kucera (the presenter) at the Face-to-Face Symposium in Baltimore: YES NO

  4. What is the most common element on the Sun?

  5. Alex Lutkus

  6. Sun Scale Facts: - You can fit 109 Earths across the disk of the Sun - Driving at a speed of 55 mph it would take almost 200 years to drive from Earth to the Sun Alex Lutkus

  7. Let’s do a poll question! What state of matter is the Sun?

  8. The Sun: Visible Light Sept. 22, 2000 SOHO/MDI

  9. The Sun: Ultraviolet Light, Sept. 22, 2000 SOHO/EIT 286 A

  10. The Sun Sept. 22, 2000 SOHO/MDI SOHO/EIT 286 A

  11. The Sun Radiates More than Just Light Coronal Mass Ejections (CMEs) SOHO/LASCO, ESA & NASA The Sun’s Corona in Visible Light

  12. Question: How long does it take for radiation from a CME to travel from the Sun to the Earth?

  13. High Energy Protons from the Sun (a.k.a Solar Energetic Particles or SEPs) SOHO/LASCO July 14, 2000 NASA & ESA

  14. UC Berkeley

  15. Solar Magnetic Loops TRACE NASA

  16. Solar Cycle NASA

  17. Solar Max or Solar Min? SOHO/MDI, ESA & NASA SOHO/MDI, ESA & NASA

  18. Solar Max or Solar Min? SOHO/EIT ESA & NASA

  19. Solar Max or Solar Min? Windows to the Universe http://www.windows.ucar.edu

  20. Earth’s Magnetosphere Without the solar wind the Earth’s magnetic field would be like a bar magnet. The solar wind compresses it on the Sun-ward side and stretches it on the far side. Windows to the Universe http://www.windows.ucar.edu

  21. Question: Does anyone know any of the ways that solar activity can affect Earth or human activities? Press *6 to unmute your phone and respond

  22. Solar Activity - Space Weather Solar Flare Intense Extreme UV, X-rays Arrival: 8 min Solar Energetic Particles (SEPs) Arrival: 15 min - hours Protons at almost the speed of light Coronal Mass Ejection (CME) Arrival: 1 - 4 days Magnetic field and plasma Flare Big Bear Solar Observatory SEPs SOHO/EIT, ESA & NASA CME SOHO/LASCO, ESA & NASA

  23. Space Weather: CMEs and Geomagnetic Storms Windows to the Universe http://www.windows.ucar.edu

  24. Space Weather: CMEs and Geomagnetic Storms Some Results: Aurora, Power System Problems Public Service Electric & Gas Corp. Image courtesy of Jan Curtis.

  25. Have you seen an Aurora? Where were you?

  26. Aurora from Space POLAR NASA

  27. Space Weather: Drag on Satellites in Low Earth Orbit Flares heat outer atmosphere causing increased drag on satellites Hubble Space Telescope drops 10-15 km per year After a big flare 100’s of spacecraft have to be relocated NASA STS-103

  28. Space Weather: Radiation Hazards to Spacecraft and Astronauts NASA

  29. Space Weather: Communications Problems Windows to the Universe http://www.windows.ucar.edu

  30. Spacecraft NASA

  31. STEREO - just launched NASA

  32.
