Jupiter + Fireball

Jupiter's had it tough lately: Almost a year after an asteroid impact had left a dark scar on the planet, another fireball was spotted smacking the planet's bottom. In the picture above, taken from Australia, the Earth-size fireball appears as a bright spot at right.

On June 3 backyard astronomers in both Australia and the Philippines saw the white flash—evidence of an as yet unidentified object slamming into Jupiter.
