Hubble space telescope saw the first large impact, then watched as the fragments continued to collide.

The planet was affected and material from below the cloud layers was thrown up into Jupiter’s upper atmosphere.

Scientists are looking for comets and asteroids that might hit Earth not Jupiter. We are lucky to have the outer gas giants because their gravity can stop some of them getting through to us!
