4. We highlight some radio astronomy projects promoted by renowned institutions around the Globe, relatively accessible in terms of level of knowledge required, availability of the equipment, and investment. These projects are addressed to high school and university students as well as to amateur astronomers, and involve the participants in a wide range of hands-on activities, from building, assembling, and calibrating the hardware setup to analyzing and sharing the data over the internet, all in a interdisciplinary learning process.

5. is a non-profit scientific, educational corporation, founded in 1989 by a team of NASA employees investigation of very low frequency (VLF = 0 Hz to over 100 kHz) radio signals in the earth's magnetosphere These signals are both manmade and naturally occurring (most of which originate from lightning) Interactive NASA Space Physics Ionosphere Radio Experiments"

8. Radio Meteor Observation meteoroids disintegrate at an altitude of 80 to 130 km the trails they leave behind are full of ionized gases that reflect radio waves distant VHF(30MHz-300MHz) radio signals can bounce off the meteor trail (forward scattering method) can monitor meteor activity regardless the weather conditions and at daytime

9. Radio detection of meteors Transmitter Continuous wave (FM carrier) Receiving station

10. Radio Meteor Observation Experimental setup FM radio receiver with digital frequency readout ( SSB receiver Black box + PC interface + PC soundcard )

14. is an education project to build and distribute inexpensive ionospheric monitors to students around the world the monitors detect solar flares and other ionospheric disturbances Earth's ionosphere reacts strongly to the intense x-ray and ultraviolet radiation released by the Sun during a solar event the signal strength from a distant VLF transmitter, reflected by ionosphere, will follow this changes SID Sudden Ionosphere Disturbance monitor

17. NASA Radio Jove Project was conceived in 1997 by a team headed by Jim Thieman at Goddard Space Flight Center sold its first receiver kit 1999 (10 th anniversary – almost 1400 kits sold) observe and analyze natural radio emissions of Jupiter (bursts), the Sun (Solar flares), and our galaxy (transit)
