Scientists don't fully understand what's driving Jupiter's strongest auroras, but data gathered by the orbiting Juno
spacecraft hint that the electrons generating Jupiter's polar glows may be accelerated by turbulent waves in the planet's magnetic field — a process somewhat akin to surfers being driven shoreward ahead of breaking ocean waves, the researchers report today in Nature.
Since then, building and testing the
spacecraft have mostly stayed on track, but last September NASA
did push back the JWST's planned launch from October 2018 to a date between March and June 2019.

In his reading, the Viking gas chromatograph scooped up soil, heated it, and in so
