NASA's Radio JOVE project enables students and amateur scientists to observe natural radio emissions from Jupiter, the Sun, the Earth, our galaxy, etc. Participants learn about radio astronomy first-hand by building their own radio telescope from an inexpensive kit and/or using remote radio telescopes through the Internet. They also collaborate with each other through interactions and sharing of data on the network. The Radio JOVE project began in 1998. Since then, more than 2400 teams of students and interested individuals have purchased radio telescope kits and are learning radio astronomy by building and operating a radio telescope. Observers may use calibrators to make their data more scientifically intercomparable and potentially publishable with other participants and professional radio astronomers. This self-supporting, non-profit program continues to thrive and inspire new groups of students as well as individuals.
