Arthur T Knackerbracket has found the following story:

Three years of imaging observations using the international Gemini Observatory, a program of NSF's NOIRLab, have probed deep into Jupiter's cloud tops. The ultra-sharp Gemini infrared images complement optical and ultraviolet observations by Hubble and radio observations by the Juno spacecraft to reveal new secrets about the giant planet.

"The Gemini data were critical because they allowed us to probe deeply into Jupiter's clouds on a regular schedule," said Michael Wong of UC Berkeley. "We used a very powerful technique called lucky imaging," adds Wong. With lucky imaging, a large number of very short exposure images are obtained and only the sharpest images, when the Earth's atmosphere is briefly stable, are used. The result in this case is some of the sharpest infrared images of Jupiter ever obtained from the ground. According to Wong, "These images rival the view from space."

Gemini North's Near Infrared Imager (NIRI) allows astronomers to peer deep into Jupiter's mighty storms, since the longer wavelength infrared light can pass through the thin haze but is obscured by thicker clouds high in Jupiter's atmosphere. This creates a "jack-o-lantern"-like effect in the images where the warm, deep layers of Jupiter's atmosphere glow through gaps in the planet's thick cloud cover.

The detailed, multiwavelength imaging of Jupiter by Gemini [and] Hubble has, over the past three years, proven crucial to contextualizing the observations by the Juno orbiter, and to understanding Jupiter's wind patterns, atmospheric waves, and cyclones. The two telescopes, together with Juno, can observe Jupiter's atmosphere as a system of winds, gases, heat, and weather phenomena, providing coverage and insight not unlike the network of weather satellites meteorologists use to observe Earth.

On each of its close passes over Jupiter's clouds, Juno detected radio signals created by powerful lightning flashes called sferics (short for atmospherics) and whistlers (so-called because of the whistle-like tone they cause on radio receivers). Whenever possible, Gemini and Hubble focused on Jupiter and obtained high-resolution, wide-area maps of the giant planet.

Juno's instruments could determine the latitude and longitude coordinates of clusters of sferic and whistler signals. With Gemini and Hubble images at multiple wavelengths, researchers now can probe the cloud structure at these locations. By combining these three pieces of information the research team found that the lightning strikes, and some of the largest storm systems that create them, are formed in and around large convective cells over deep clouds of water ice and liquid.

    No mention of the fact that Gemini North is located atop the Hawaiian mountain of Mauna Kea? Did Aquaman get here first, and demand an erasure?

    When is a frog a dog?
    Why do you keep snorting coke
    It makes you limp and the ladies laugh

    I don't know why I like to snort
    It's my stimulant warrior fort
    I don't know why I like to snort
    I laugh at the judge in the kangaroo court

    Have you ever stepped into a beam of light
    Or have one blind you so terribly
    The creatures are easily defeated

    I don't know why I like to snort

    Cocaine is a hell of a drug, they say
    Slipping away in a sewer
    The ultimate freedom and horror
    Horror
    Horror
    Horror
    The chickens are mine.

      I'll raise your frog...
      with one gypsy qween...

      Lightning smokes on the hillrise
      Brought the man with the warning light
      Shouting loud you had better fly
      While the darkness can help you hide
      Trouble's comin' without control
      No one's stayin' that's got a hope
      Hurricane at the very least
      In the words of the gypsy queen
      Sign of the gypsy queen
      Pack your things and leave
      Word of a woman who knows
      Take all your gold and you go
      Get my saddle and tie it on
      Western wind who is fast and strong
      Jump on back, he's good and long
      We'll resist till we reach the dawn
      Running seems like the best offense
      Staying just don't make any sense
      No one could ever stop it now
      Show the cards of the gypsy town
      Sign of the gypsy queen
      Pack your things and leave
      Word of a woman who knows
      Take all your gold and you go
      Shadows movin' without a sound
      From the hold of the sleepless town
      Evil seems to be everywhere
      Heed the spirit that brought despair
      Trouble's comin' without control
      No one's stayin' that's got a hope
      Hurricane at the very least
      In the words of the gypsy queen
      Sign of the gypsy queen
      Pack your things and leave
      Word of a woman who knows
      Take all your gold and you go
      Sign of the gypsy queen
      Pack your things and leave
      Word of a woman who knows
      Take all your gold and you go
      Sign of the gypsy queen
      Pack your things and leave

      Rungs To Riches

      I spun the wheel and placed it all on black
      The wheel began to transform into a wheel of fire
      A squirrel was tap dancing around the flames

      I could not go back to that Casino
      I could not go back to that Casino

      Donkeys are sometimes said to fly like pigs
      Well then I raise you one chicken and two dead gophers

      I could not go back to that Casino
      It was bloodier than a movie by Tarintino.
      Ducks and chickens ripping each other apart with razor feet
      Lady luck wasn't there for the players in the game but for the game itself

      I felt myself growing rather dizzy

      I could not go back to that Casino

      My anus is fortified by a labia covering

      Feed me to the vultures when I go
      I don't want to be the last to crow

      Squeezing of breasts everywhere

    '...takes a deep dive into Jupiter's clouds'

    Really?
    Let us fix this abomination.

    "The Gemini North Telescope(also known as the High Jump Scope), just engaged it's super-secret Atomic Flea Drive and jumped all the way from it's usual parking spot on a mountain top in Hawaii, to Jupiter's atmosphere. There it engaged it's Lucky Camera to dive into the clouds. In the clouds, the Lucky Camera lived up to it's name, and Gemini North caught a jack-o-lantern, which surprised all, as pumpkins were thought to be extinct in Jupiter's Clouds.

    As usual, the British judges only gave it a mediocre score of 6 for the dive, whilst other judges scored in the 8-9 point range."

    There, that's better. Now TFS matches up with the headline much better.

    From the article...

    END

    Jeez, did astronomers just discover that if you take a bunch of snaps, you might end up with a keeper? Non-Phds around the world claim prior art on this "powerful imaging trchnique."
