NASA has announced that it chose Ultima Thule as a nickname for 2014 MU69, the Kuiper Belt Object that represents the next target for its New Horizons space probe. In recent months, the mission team asked for suggestions on the Internet and then opened a ballot allowing to select the favorite among the nicknames selected among the thousands of proposals. The result is not an official name, which must be ratified by the International Astronomical Union (IAU), because it’s not clear if Ultima Thule is a single object.

Four articles published in the journal “Nature” describe as many researches on the planet Jupiter. Different teams of researchers focused on different phenomena using data collected by NASA’s Juno space probe. The researches concerns groups of huge cyclones present in Jupiter’s polar regions, wind flows that extend up to thousands of kilometers of depth, the stripes of the atmosphere that rotate at different speeds and the asymmetries in the planet’s gravitational field.
