6. Magnetospheres
A magnetosphere is a large electromagnetic field that surrounds planets and other celestial bodies.
Jupiter’s magnetosphere is larger than anything else in the solar system, including the sun.

8. Magnetosphere
Jupiter’s Magnetosphere emits radio waves.

9. Magnetosphere Jupiter’s Magnetosphere emits radio waves.
Jupiter’s satellites create a ring of electrons, the torus.

10. Magnetosphere Jupiter’s Magnetosphere emits radio waves.
Jupiter’s satellites create a ring of electrons, the torus.
A charged particle accelerating through a magnetic field will experience a force and emit electromagnetic radiation.

11. Solar Radio Emissions Type II solar emissions
Electron interference with solar winds.

12. Solar Radio Emissions Type II solar emissions
Electron interference with solar winds.
Type III solar emissions
Particle collisions in the solar wind cause radio wave emission.
Solar flares release electromagnetic radiation across the spectrum.
Solar bursts are caused by solar flares and emit radio waves close to 20 MHz.

13. Hypotheses
1. No signals
2. Just “noise”
3. Solar activitiy

14. Alternative Hypothesis that we have not fully REJECTED:
Little green mathematicians!!

15. Radio Telescope - Antenna
Function
Intercepts radio waves and converts them to electrical current
Designed to detect waves of frequency 20.1 MHz
Explain WHY half the wavelength is necessary

16. Radio Telescope - Antenna
Construction
Each dipole is approximately 7 meters, slightly less than λ/2. (λ = m)

17. Center Insulator

21. Problems Solutions Diodes Tuner SA602 chip Orient them correctly
Forget about it.
Unfixable

22. Spend $300 and buy two receivers from Radio Shack.
ULTIMATE SOLUTION:
Spend $300 and buy two receivers from Radio Shack.
