Live coverage: NASA’s Juno spacecraft arrives at Jupiter

Early risers in the UK with an unobstructed horizon from southeast through south can see the old crescent Moon close to dazzling Venus in Libra then Jupiter in Ophiuchus over three consecutive mornings starting New Year’s Day around 7am GMT. The brightest and largest planets lie little more than the span of an outstretched hand at arm’s length apart at this time.

NASA’s Cassini spacecraft sped through a gap between Saturn and its rings for the second time Tuesday after data from the probe’s first perilous passage through the unexplored region last week found it to contain fewer potentially hazardous dust particles than expected.

Taking advantage of a rare orbital alignment between two of Jupiter’s moons, Io and Europa, researchers have obtained an exceptionally detailed map of the largest lava lake on Io, the most volcanically active body in the solar system.
