Auroral Activity On Jupiter — All As Imaged By Juno…

We promised we’d link this development, and now we have.


Do go read more about it all, at the NASA / JPL Juno Mission’s web HQ — it includes nice videos of the data, as well:

. . .“Observing Jupiter’s aurora from Earth does not allow you to see beyond the limb, into the nightside of Jupiter’s poles. Explorations by other spacecraft – Voyager, Galileo, Cassini – happened from relatively large distances and did not fly over the poles, so they could not see the complete picture,” said Bertrand Bonfond, a researcher from the University of Liège in Belgium and lead author of the study. “That’s why the Juno data is a real game changer, allowing us a better understanding what is happening on the nightside, where the dawn storms are born.”



Researchers found dawn storms are born on the nightside of the gas giant. As the planet rotates, the soon-to-be dawn storm rotates with it into the dayside, where these complex and intensely bright auroral features grow even more luminous, emitting anywhere from hundreds to thousands of gigawatts of ultraviolet light into space. The jump in brightness implies that dawn storms are dumping at least 10 times more energy into Jupiter’s upper atmosphere than typical aurora. . . .



“The power that Jupiter possesses is amazing. The energy in these dawn aurorae is yet another example of how powerful this giant planet really is,” said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio. “The dawn storm revelations are another surprise from the Juno mission, which is constantly rewriting the book on how giant planet’s work. With NASA’s recent mission extension, we’re looking forward to many more new insights and discoveries
. . . .”

Now you know, and. . . stay safe and dry, down there, south of us here. . . smiling.
