Watch the king of the planets turn on its throne

A newly discovered planet orbiting a star known as HIP 11915 is the most accurate analogue yet found for the Sun and Jupiter. HIP 11915 is about the same age and composition as the Sun, suggesting that there may also be rocky Earth-like planets orbiting closer to the star.

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 Juno spacecraft is barreling toward a rendezvous with Jupiter after a 2.8 billion kilometre (1.7-billion-mile), five-year trip from planet Earth. The research probe’s main engine will ignite for 35 minutes to maneuver Juno into orbit, and engineers expect to receive confirmation of burn’s start at 0318 GMT Tuesday.
