New Horizons

The New Horizons spacecraft is NASA's more recent solar system explorer and is currently on its way to Pluto to study the relatively unknown dwarf planet. On its way, it stopped by Jupiter (last week) in order to give it an extra boost and decrease its transit time significantly. Luckily, however, it passed by Jupiter during some interesting activity on the surface and in the Jovians rings.
A meteorite had hit the rings shortly before the arrival of the spacecraft, sending up debris and collecting some of the meteorite itself. This allowed New Horizons to see a more specialized and detailed sample of the material making up the disc (and meteorite).
Another interesting find was a bit of bad weather in the polar region and storms making up the little red spot. The lightning in the pole suggested "thunderheads the size of a Western state" and the little red spot (a new, smaller version of the diminishing great red spot) provided more evidence for the theory surrounding the storms on Jupiter's surface.
Other nice finds included a 200 mile jet from a volcano on Io and a closer look at the atmosphere. The article can be found here:
