I cicloni di Giove

La NASA ha pubblicato una nuova foto, scattata dalla sonda Juno, che mostra il polo sud di Giove coperto da giganteschi cicloni alcuni dei quali presentano un diamero di 1.000 km. L'immagine solleva nuove interessanti domande sulle dinamiche climatiche che interessano i poli del gigante gassoso.

Among the findings that challenge assumptions are those provided by Juno's imager, JunoCam. The images show both of Jupiter's poles are covered in Earth-sized swirling storms that are densely clustered and rubbing together.

"We're puzzled as to how they could be formed, how stable the configuration is, and why Jupiter's north pole doesn't look like the south pole," said Bolton. "We're questioning whether this is a dynamic system, and are we seeing just one stage, and over the next year, we're going to watch it disappear, or is this a stable configuration and these storms are circulating around one another?"
