NASA’s Juno probe entered Jupiter’s orbit in the fading hours of July 4, giving American researchers one more reason to celebrate. The spacecraft, which
will study the solar system’s biggest planet in closer detail than ever before, traveled for almost five years across some 1.7 billion miles. Named after
the mythological god Jupiter’s wife, who could see through her husband’s tricks, Juno will peer through the planet’s atmosphere, measure its composition
and map its powerful magnetosphere. Early findings revealed unique storm systems on the planet’s north pole and a surprising depth to its ribbon-like cloud
patterns. After the 20-month mission, the probe will plummet into Jupiter’s clouds.
