1. In 1955 researchers discovered the planet Jupiter produced radio waves. For over 58 years these mysterious storms have been studied by radio astronomers and NASA probes. These storms are caused by interactions with Jupiter’s magnetic field and its many moons, especially the volcanic moon Io. Radio spectrographs in the frequency range of 18-25 MHz detect these events. Io’s radio storms can be somewhat predicted, as the storms occurrences are dependent upon Io’s orbital positions with respect to the Earth. These orbital positions indicate the type of storm using a source scale of Io A, B, C, and non-Io events. One of the remaining mysteries is why do intense non-IO storm events occur at all? This question is being investigated by Project Juno, a NASA space probe arriving on Jupiter in 2016. This visualization project was focused on creating Jupiter storm spectrograph catalog from the Clemson University’s Mountain Rest Astronomical Observatory (MRAO) over the first three years of operation (2012-2015). The visualization tools were used to track storms in outer space. These tools include Radio-sky, Radio-spectrograph, and Radio-eyes. Cataloging data was the first step in the project. Then data analysis was done on selected storm events to test the hypothesis that Jupiter’s inner moons may contribute to the non-IO storm events. Finally, this catalog was published on the Microsoft Worldwide Telescope portal, a free resource for all astronomers and public. The Methodology was to monitor the spectrograph to see where the storm events took place and on which dates and specific times. We used a monitoring system to track Io’s position in the time storms were found on these spectrographs. Visualization of Jupiter’s Radio Storms Paris Smith, Jackson State University Dr. Andrew Mount, Clemson University REU Site: Research Experience for Undergraduates in Collaborative Data Visualization Applications June 1 – July 24, 2015 Clemson University Clemson, South Carolina Advanced Visualization Division REU Funded by NSF ACI Award 1359223 Dr. Vetria Byrd, PI Abstract The results show that there is a storm taking place with some direct phase of Io(A, B, C). The reason for the storm is the flux tube around Jupiter is interacting with the volcanic eruptions of moon Io. Most of our data indicated that these radio emissions were caused by moon IO, however we have some radio emissions that were not caused by moon Io. We believe that non-Io events were either a reaction of Jupiter or Io with another moon. Figure 2. The wave lengths and intensity colors indicates a storm taking place. Introduction This project was motivated by radio emissions found in spectrographic data coming from planet Jupiter. The goal is to analyze all of these spectrographs to understand the activity taking place. Figure 3. Shows the storm in Figure 1 was an Io-C storm. Figure 6. Shows that the storm in Figure 3 was a non-Io storm. Figure 5. The spectrograph shows a storm is occurring. Background Find a Storm Note date and time Inspect Io’s orbital position Speculate non-Io storms In 1955 were researchers discovered radio emissions coming from planet Jupiter. It was later discovered that planet Io and its volcanic moon were the cause of these storms. We tracked these storms using a spectrograph, an instrument that separates light into a frequency spectrum and records the signal using a camera. Figure 1. Jupiter's magnetosphere is the largest and most powerful of any planetary magnetosphere in the Solar System. This image visualizes the magnetosphere and how it connects to its moons.
