IIRC, the Giant Red Spot is about three Earths in diameter, so that flash is several thousand miles across.
Yeah, talking extinction-level impact if something like that hit the earth...
I took the wrong exit on the freeway.
Sorry y’all.
The Great Red Spot’s diameter is just over 10K miles. The flash in the photo is 7/40ths the diameter of the Spot. Therefore the flash created by the impact of the object - meteor, asteroid, comet, whatever - seems to have been nearly two thousand miles in diameter. The 1994 impact of Comet Shoemaker-Levy 9’s .62 miles in diameter pieces left much larger splotches in Jupiter’s upper atmosphere, so the thing that left this more recent mark may be inferred to have been significantly smaller.
