WASHINGTON (Reuters) - A NASA spacecraft observed lightning strikes at Jupiter's poles as it provided insights into the giant planet's dynamic atmosphere as well as volcanic activity on one of its moons, scientists said on Tuesday.
The New Horizons spacecraft, passing by the solar system's largest planet en route to the dwarf planet Pluto, also snapped images of the tiny rings encircling Jupiter, studied a huge, swirling storm and explored the planet's long magnetic tail.
