Meteor Caused Jupiter Flash, Hubble Reveals
The Hubble telescope has not found a dark debris field, suggesting a smaller meteor and not a large asteroid or comet hit Jupiter.
The Hubble found no trace of a dark debris field following the distinctive burst, which appeared for two seconds on June 3 and was spotted separately in videos taken by amateur astronomers Anthony Wesley of Australia and Christopher Go of the Philippines.

To investigate the size of the impact, Hubble's ultraviolet and visible-wavelength cameras were called into action three days after the blast. However, they found no telltale black smudges,
