    Consider my mind boggled.
    "A MAJOR scientific breakthrough has been discovered by two separate research teams who have glimpsed the “fourth dimension”, it has been revealed.
    Since Albert Einstein developed the theory of relativity in 1905, the fourth dimension usually meant time.
    But, two teams in the US and another in Europe have shown the existence of a fourth spatial dimension.
    Mikael Rechtsman from Penn State University said: "Physically, we don't have a 4D spatial system, but we can access 4D quantum Hall physics using this lower-dimensional system because the higher-dimensional system is coded in the complexity of the structure.
    "Maybe we can come up with new physics in the higher dimension and then design devices that take advantage the higher-dimensional physics in lower dimensions."
    In layman’s terms, 3D objects cast 2D shadows, so 4D objects should cast 3D shadows even if the 4D object is imperceivable.
    The two teams created two custom-designed, two-dimensional experiments to generate an instance of the quantum Hall effect, which restricts the movement of electrons which allows us both to perceive and measure them.
    Researchers who studied the effect managed to win the 2016 Nobel Prize for Physics and three Nobel Prizes have been awarded for experimental and theoretical work for the effect.
    The effect normally manifests itself in the boundary between two materials, where electrons can only move in two dimensions."

    Still never actually seen the Northern Lights.
    "As charged particles streaming from the sun collide with Earth’s magnetosphere, interactions with different gases create stunning displays of green, red, and purple that appear to dance across the sky.
    It's no great mystery what causes these incredible light shows, known as the Northern and Southern Lights, which often spring up over Earth’s poles.
    But, until now, the process behind a particular type of aurora that appears as though it's 'blinking' has never been observed directly.
    Using a sensor aboard the Japan Aerospace Exploration Agency’s Arase spacecraft, scientists have finally captured a look at the ‘shower of electrons’ falling to Earth, revealing new insight on the mechanisms behind the auroral phenomenon.
    Among the different types of auroras are pulsating auroral patches, which commonly appear at dawn.
    The mechanisms driving the phenomena have long remained elusive – but, with the latest measurements, scientists have pinpointed the interaction between electrons and plasma waves that causes them to appear.
    ‘Auroral substorms are caused by global reconfiguration in the magnetosphere, which releases stored solar wind energy,’ writes Satoshi Kasahara, an associate professor in the Department of Earth and Planetary Science at the Graduate School of Science of the University of Tokyo.
    ‘They are characterized by auroral brightening from dusk to midnight, followed by violent motions of distinct auroral arcs that eventually break up, and emerge as diffuse, pulsating auroral patches at dawn.’"

    Didn't one of the space probes have a recording of Johnny B. Goode aboard?

    2 actually, Voyager 1 & Voyager 2 each carry an identical gold record with some 90 minutes of Earth music on, and Johnny B. Goode is one of the tracks.

    This is fascinating.
    "Earth's magnetic field has been mapped from space in stunning new detail.
    A new movie shows thousands of tiny fluctuations in Earth's magnetic signals created by ocean tides and our planet's rigid outer layer, known as its 'lithosphere'.
    The European Space Agency used three satellites to build the map, which it says is the most detailed ever rendering of magnetic fluctuations across Earth's crust.
    The magnetic field is a layer of charge that surrounds our planet and deflects charged particles fired from the sun known as 'solar wind'.
    Without this protective layer, these particles would likely strip away the Ozone layer, our only line of defence against harmful UV radiation.
    The map, which is being used to understand more about Earth's geological history, is thanks to four years of measurements from the agency's Swarm satellites.
    Imagery from the spacecraft was combined with historical data from a previous German spacecraft called Champ and observations from ships and aircraft.
    Project scientist Dr Erwan Thebault from the University of Nantes in France said: 'This is the highest resolution model of the lithospheric magnetic field ever produced.
    'With a scale of 250 kilometres [155 miles], we can see structures in the crust like never before.
    'And, we have gained even finer detail in some parts of the crust, such as beneath Australia, where measurements from aircraft have mapped at resolution of 50 km [30 miles].
    'This combined use of satellite and near-surface measurements gives us a new understanding of the crust beneath our feet, and will be of enormous value to science.'"

    And so is this, if you'll indulge me and forgive a bit of non-Astronomy.
    "Humans have been studying the anatomy of our own bodies for thousands of years – but, to this day, scientists are still uncovering new secrets.
    A team of researchers has identified what’s said to be a previously undiscovered organ, and may even be one of the largest in the body.
    What was once thought to be dense, connective tissues running all throughout the body has now been found to be a network of fluid-filled compartments that may act as ‘shock absorbers.’
    Not only could the finding reshape our understanding of the human body, but scientists say it could help to explain why cancer is more likely to spread when it invades certain areas.
    The NYU-led team says the newly discovered organ is found all over the body – but somehow, it hasn’t been identified until now.
    Dubbed the ‘interstitium,’ interconnected compartments act like a ‘highway of moving fluid’ that sits beneath the top layer of the skin, lines the digestive tract, lungs and urinary systems, and surrounds the arteries, veins, and the fascia between muscle.
    The human body contains huge amounts of fluid.
    More than half of this is found within the cells, and another seventh inside the heart, blood vessels, lymph nodes, and lymph vessels. The rest is known as interstitial.
    Now, researchers say the network that carries this interstitial fluid is its own distinct organ.
    And, it may even be one of the largest organs in the body."

    "In the decades since the first grainy images beamed back to Earth to reveal our first close looks at Saturn and its moons, Titan has remained veiled in mystery.
    The landing of the Huygens probe in 2005 brought us closer than ever before to a distant moon, showing the surface of Titan to be an ‘alien Earth,’ with methane rains and rivers, towering sand dunes, and a subsurface water ocean.
    But, the probe died just 72 minutes after touching down, leaving the Cassini spacecraft to carry on its observations alone, from orbit.
    Save for some mosaics mapping the surface, which suffered ‘seams’ from variations in resolution and lighting, the common image of Titan is of a cue ball moon blanketed completely in a thick haze.
    Now, using 13 years of data from Cassini’s Visual and Infrared Mapping Spectrometer (VIMS) instrument, NASA has stitched together the most detailed global view yet, showing what Titan might look like if one could see right through its dense atmosphere."

    Misleading headline, but interesting.
    "Gamma ray bursts identified erupting from deep space have been found to exhibit some of the most bizarre galactic behaviour ever observed, scientists say.
    The six extremely high energy bursts of electromagnetic energy, which were identified more than years ago, showed evidence of complex time-reversible wavelike behaviour – in which time itself appears to repeat backwards.
    Scientists do not believe the behaviour is evidence of time travel.
    Instead, they now think the repeating emissions are like a high speed release of charged particles that bounces around in galactic debris, like an echo.
    This generates an unusual signal that is then further distorted by interference – or noise – over billions of light years, scientists say.
    Understanding the phenomenon could help us understand more about the death of massive stars and even the formation of black holes"

    "Mars hung low over my shoulder, close and bright and fiery, as I stood on a causeway across the Banana River Sunday (Aug. 12) here at Cape Canaveral Air Force Station. A slight breeze kept the mosquitoes away, and Perseid meteors popped up every now and again, carving brief and slender slivers of light into the predawn sky.

    And then, at 3:31 a.m. EDT (0731 GMT), that dark sky lit up in a flash of brilliant orange as a United Launch Alliance Delta IV Heavy rocket, one of the most powerful boosters flying today, lifted off the pad."

    "Earth's magnetic fields are shifting - and scientists are unsure why.
    Researchers say the magnetic North Pole is 'skittering' away from Canada, towards Siberia.
    The problem has got so bad, researchers around the world are scrambling to update a global model of the fields.
    Called the World Magnetic Model, it underlies all modern navigation, from the systems that steer ships at sea to Google Maps on smartphones.
    The most recent version of the model came out in 2015, and it was supposed to last until 2020.
    However, researchers say the magnetic field is changing so rapidly that they have to fix the model urgently.
    It was due to be updated on the 15th January, but due to the US Government shutdown, that has already been delayed until the 30th.
    The magnetic field is in a permanent state of flux.
    Magnetic north wanders, and every few hundred thousand years the polarity flips so that a compass would point south instead of north.
    'The error is increasing all the time,' Arnaud Chulliat, a geomagnetist at the University of Colorado Boulder and the National Oceanic and Atmospheric Administration's (NOAA's) National Centers for Environmental Information, told Nature.
    'In early 2018, as part of our regular assessment of the WMM, we found that the model exceeded its specification for declination only three years into the five-year WMM cycle,' he told the American Geophysical Union meeting.
    'We investigated this error and tracked it down to the combined effect of a global geomagnetic acceleration pulse occurring in 2015-2016, and a fast-changing magnetic field in the North polar area.
    'A remarkable manifestation of the field variation is the drift of the North magnetic pole towards Russia, which has been occurring at the unusually high speed of about 50 km per year since the beginning of the 21st century.
    'On the contrary, the South magnetic pole drift is very slow (less than 10 km per year) and has not changed much over the past few decades, and hence provided a much smaller contribution to the overall model declination error.'
    To fix the model, he and his colleagues fed it three years of recent data, which included a 2016 geomagnetic pulse, and he says the new model, when it is released, should remain accurate until the next regularly scheduled update in 2020.
    Satellites such as the European Space Agency's Swarm mission tracked the shift.
    Phil Livermore, a geomagnetist at the University of Leeds, UK, said at the American Geophysical Union meeting 'the location of the north magnetic pole appears to be governed by two large-scale patches of magnetic field, one beneath Canada and one beneath Siberia,' Livermore says.
    'The Siberian patch is winning the competition.' "

    Yeah, this came up in a class I took at Purdue. The "flip" won't be noticed by anyone who doesn't use the poles to migrate every year. (At least that was the word before GPS became ubiquitous.)
