Following the alert by Australian amateur astronomer Anthony Wesley, professional astronomers have been able to confirm the impact nature of the new dark spot appeared on July 19th on the surface on Jupiter.
See our previous post for more information:
The clue arrived from near-infrared image of the upper atmosphere above the impact site:
"An impact would make a splash like a stone thrown into a pool, scattering material in the atmosphere upwards. This material would then reflect sunlight, appearing as a bright spot at near-infrared wavelengths"
"Our first image showed a really bright object right where that black scar was, and immediately we knew this was an impact," astronomer Glenn Orton says. "There's no natural phenomenon that creates a black spot and bright particles like that."
