Jupiter may have a new ring that was created by a smash between moons.
The possible ring appears as a faint streak near Jupiter's moon Himalia in an image taken by NASA's New Horizons spacecraft. The telescopic camera aboard the Pluto-bound probe snapped the ring in September 2006 as the craft was closing in on Jupiter in the lead-up to a close encounter with the planet the following February.
Jupiter's new "ring" appears as a diagonal streak in this
composite of six images; the moon Himalia lies within the
white circle. (LORRI)
