The regular imaging of Jupiter by Hubble and Gemini in support of the Juno mission is proving valuable in studies of many other weather phenomena as well, including changes in wind patterns, characteristics of atmospheric waves and the circulation of various gases in the atmosphere.
Hubble and Gemini can monitor the planet as a whole, providing real-time base maps in multiple wavelengths for reference for Juno’s measurements in the same way that Earth-observing weather satellites provide context for NOAA’s high-flying Hurricane Hunters.
“Because we now routinely have these high-resolution views from a couple of different observatories and wavelengths, we are learning so much more about Jupiter’s weather,” explained Simon. “This is our equivalent of a weather satellite. We can finally start looking at weather cycles.”
Because the Hubble and Gemini observations are so important for interpreting Juno data, Wong and his colleagues Simon and de Pater are making all of the processed data easily accessible to other researchers through the Mikulski Archives for Space Telescopes (MAST) at the Space Telescope Science Institute in Baltimore, Maryland.
“What’s important is that we’ve managed to collect this huge data set that supports the Juno mission. There are so many applications of the data set that we may not even anticipate. So, we’re going to enable other people to do science without that barrier of having to figure out on their own how to process the data,” Wong said.
The results were published in April 2020 in The Astrophysical Journal Supplement Series.
