'New views of Jupiter' showcases swirling clouds on giant planet

Members of NASA’s Juno mission team, some of the world’s leading observers of Jupiter, and citizen scientists from across the globe attended a workshop co-organised by Leicester academic entiteld ‘New Views of Jupiter: Pro-Am Collaborations during and beyond the NASA Juno Mission’ at the Royal Astronomical Society in London on 10-11 May.

JunoCam images presented at the meeting by citizen scientists Gerald Eichstädt and Seán Doran include an animation showing the evolution of swirling features in the giant planet’s atmosphere and a composite image of Jupiter’s cloud tops.

Seán Doran, in collaboration with Eichstädt, has created a new composite image of Jupiter as seen by Juno as it swung away from Jupiter’s south pole on 1st April 2018. Because Jupiter was larger than JunoCam’s field of view when the main portion of the image was taken, Eichstädt rendered four other images to the same viewing geometry to reconstruct a mosaic of the whole planet. Doran then processed the composite image to balance and blend the overlapping components, sharpen the contrast, and fill gaps.

Leigh Fletcher from our Department of Physics and Astronomy, who has co-organised the workshop with the support of Europlanet 2020 Research Infrastructure, says: “The contribution of the Earth-based support campaign to the Juno mission, both professional and amateur, has proven to be invaluable in filling the spatial, temporal, and spectral gaps in Juno’s capabilities.  Now two years into the mission, we’ve seen some tremendous new science emerging from this collaboration, and breath-taking imagery of Jupiter’s complex atmosphere that would not have been possible without the talented army of citizen scientists that have been working alongside the JunoCam team every step of the way.”
