1. Planetary Radio Emissions Discovery Site Marker
In 1955 scientists Bernard Burke and Kenneth Franklin from the Carnegie Institution of Washington accidentally discovered naturally-generated radio waves from Jupiter using a 96-acre antenna array. The discovery led to greater understanding of planetary magnetic fields and plasmas and opened a new window in our exploration of the solar system.
