Sent primarily to investigate the origin and evolution of Jupiter, Juno has been able to take in bonus observations of the planet's four major moons - Callisto, Ganymede, Europa and now Io.

It performed its close flyby of Ganymede in 2021, and of Europa earlier this year.

These passes produced some novel insights from Juno's microwave radiometer.

Intended to look deep into the clouds of Jupiter, this instrument has also been able to see down through the ice layers of Ganymede and Europa for tens of kilometres.

These two moons are of particular interest because they're both thought to hide a global ocean of liquid water at depth.

The European Space Agency's Juice probe will leave Earth next year and will focus its attention on Ganymede. Nasa's Clipper satellite will launch in 2024 and will orbit Europa.

Thanks for the post. Interesting stuff there.

Io, Io, to Jupiter I go... (insert whistling here)

At Europa, the temperatures are lower but vary less from place to place. And interestingly, they become very uniform at depth.

We all know what's happening at Europa...

I loved the movie “Outland” with Sean Connery, based on Io. Such a beautiful movie.
