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.

Magnetosphere Jupiter’s Magnetosphere emits radio waves.

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

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.

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

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.

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

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

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

Radio Telescope - Antenna Construction Each dipole is approximately 7 meters, slightly less than λ/2. (λ = 14.925 m)

Center Insulator

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

Conclusion Hypotheses confirmed Jupiter Solar emissions …and…

Surprise! Meteors!

and especially the one who makes us excited… Acknowledgements State of New Jersey Drew University Brian Holton Dr. Miyamoto Dr. Surace taxpayers like you! and especially the one who makes us excited…

Oh yeah!
