(14 May) James Webb telescope reveals ’impossible’ auroras on Jupiter that have astronomers scratching their heads

Scientists looked at Jupiter’s massive auroras using the James Webb and Hubble Space Telescopes — and found a mystery they can’t fully explain.

#Musk 1st announced his intention to build #space-based #internet, which he would eventually call #Starlink, in 2015. He had plans to settle #Mars, …the moons of #Jupiter, & maybe #asteroids too. All those space colonies would have to be connected via #satellite-based communication; Starlink itself might…be adapted for this use. Indeed, Starlink’s terms…ask customers to affirm they “recognize Mars as a free planet & that no Earth-based govt has authority or sovereignty over Martian activities.”

Evening twilight shows the bright stars of the winter constellations setting in the west. Two 'guests' are also in the frame...the moon (grossly overexposed), and Jupiter below it.

Cirrus clouds are moving in from the west, but only block the brightest parts of the twilight sky near the horizon.

The lights of La Luz shine at the bottom of the frame, right of center.

This is a wide angle image (APS-C sensor, 12mm lens), taken on a fixed tripod.

I took a series of images that started in bright twilight and continued to full night. I chose this image because it didn't show too many stars (easier to identify constellations), yet it was mixed with a nice gradient of twilight that was fairly bright near the horizon (with touches of orange and yellow) and rather dark up high.

"This result suggests that in Jupiter-like orbits, most planetary systems may not mirror our solar system," said co-author Youn Kil Jung of the Korea Astronomy and Space Science Institute, which operates the KMTNet."

I'm thinking big ol' Jupiter might hold the key as to why the inner Solar System is the way it is and why it's different from most other systems we know of so far.
