Live coverage: NASA’s Juno spacecraft arrives at Jupiter

Juno has beamed back amazing images of Jupiter’s poles taken during its recent close approach. It’s the first time we’ve seen one of the gas giant’s poles in detail since Pioneer 11 flew by in 1974.

Ripples in Saturn’s innermost rings indicate the planet’s core is a thick “soup” of material that sloshes about slightly, creating detectable gravitational fluctuations.

Using data gathered by NASA’s New Horizons spacecraft on its Pluto flyby in July 2015, the dwarf planet has some characteristics less like that of a comet and more like much larger planets, according to the first analysis of Pluto’s unique interaction with the solar wind — the charged particles that spew off from the Sun into the solar system at a supersonic 1 million mph.
