back to article Jupiter's throwing a firework party for Juno – and Hubble's peeking in

The Hubble Space Telescope has captured new images of Jupiter’s glowing aurora swirling around one of the planet’s poles, as part of a wider observation programme of the gas giant. NASA’s Juno spacecraft is expected to descend into Jupiter on 5 July at 0418 BST, when Mission Juno will commence. The trip to Jupiter is part of a …

    Fascinating stuff!

    I do however note that Juno will descend into the magnetosphere of Jupiter on July 4, not into Jupiter itself. Nice to see lots of activity as it is about to arrive.

    "Juno’s Leros 1b main engine, designed and built by Moog-ISP in Westcott, Buckinghamshire, is gearing up for a make-or-break 35-minute firing to steer the spacecraft into a wide multi-million mile ellipse around Jupiter"

      Exactly what I was thinking.

      That's no fireworks display, it's the Jovian's reaction:

      "Incoming alien ship! Activate the lightning shields!"

    The light can only be observed in ultraviolet...

    With light being the visible part, i.e. visible the the human eye, of the electromagnetic spectrum there's no light at all then. But, who knows, perhaps that changed since I was a lad.

      If that was the case the phrase "visible light" would be redundant. "Light" is one of those flexible terms like "heap", and sort of goes from where it stops being a radio wave up to where it seriously starts ripping inner electrons off atoms.

      Pint icon because it's the sort of thing that gets discussed down the pub.

        Thank you so much for that explanation. It brought clarity to the reason why, when I can't get radio waves on my receiver, the little light doesn't shine, meaning I therefore need to stoke the bloomin' thing with yet more electrons (batteries). I see now. Isn't science wonderful.

      Re: Light?

      Even though I find semantics quite boring and to be a diversion from the actual topic, it has this special kind of lure that draws me in from time to time. A lesson I learned early on though is that when you feel the urge to reach for the keyboard when the usage of a word differs from how you feel it should be used, do not go straight for the post comment button, rather go to


      a . Also called luminous energy, radiant energy. electromagnetic radiation to which the organs of sight react, ranging in wavelength from about 400 to 700 nm and propagated at a speed of 186,282 mi./sec (299,972 km/sec), considered variously as a wave, corpuscular, or quantum phenomenon.

      b. a similar form of radiant energy that does not affect the retina, as ultraviolet or infrared rays.

    Needs a more ElReg headline

    Juno going down on Jupiter's massive glowing pole?

    (Sorry, just been reading about the upswing in porn searches since last week.)

      Impressive concentration! If I tried to read about the upswing in porn searches for a whole week I would start to see things like: "Google's Madrid offices are its latest to be raided in the search for giant faeces..."

      Regrettably, the article is not about Google secretly transporting mammoths across the EU.

    A premature end?

    "NASA’s Juno spacecraft is expected to descend into Jupiter on 4 July..."

    I know US-ians like a good fireworks display for Independence Day, but isn't this just a tad excessive?

    In any case, well done to all concerned!

    Dive! Dive! Dive!

    Picked up some Juno stickers n' other stuff from the JPL table at the last Yuri's Night @ California Science center. :-)

    If you are a space geek, SoCal is one heck of a place to be. Historically (you won't believe how many ex-Apollo workers there are here. Their reminiscences are fascinating) as well as Space-X, Virgin, Orbital etc. etc.

    No surprise.

    Jupiter's sitting there surrounded by all his mistresses and NASA sends his fucking WIFE to check up on him.

    It's no wonder there's fireworks.
