Caption
SwRI scientists studied the area imaged by Juno’s UVS instrument on April 10, 2020, and determined that a large meteoroid had exploded in a bright fireball in Jupiter’s upper atmosphere. The UVS swath includes a segment of Jupiter’s northern auroral oval, appearing purely in green, representing hydrogen emissions. In contrast, the bright spot (see enlargement) appears mostly yellow, indicating significant emissions at longer wavelengths.
