    Here's one hot off the presses-
    "Saturn has overtaken Jupiter as the planet with the most moons, according to US researchers.
    A team discovered a haul of 20 new moons orbiting the ringed planet, bringing its total to 82; Jupiter, by contrast, has 79 natural satellites.
    The moons were discovered using the Subaru telescope on Maunakea, Hawaii.
    Each of the newly discovered objects in orbit around Saturn is about 5km (three miles) in diameter; 17 of them orbit the planet "backwards".
    This is known as a retrograde direction. The other three moons orbit in a prograde direction - the same direction as Saturn rotates.
    Two of the prograde moons take about two years to travel once around the ringed planet.
    The more-distant retrograde moons and one of the prograde moons each take more than three years to complete an orbit.
    "Studying the orbits of these moons can reveal their origins, as well as information about the conditions surrounding Saturn at the time of its formation," said Dr Scott Sheppard, from the Carnegie Institution for Science in Washington DC, who led the team.
    Dr Sheppard told BBC News that Jupiter had been the planet with most known moons since the late 1990s."

    "5 km"? Pluto looks on with teary eyes.

    The cynic in me thinks coincidence,
    "SCIENTISTS have been left stunned after finding galaxies millions of light-years away from each other rotating in the same direction and at the same speed, suggesting they are connected in some way.
    Researchers believe there is something fundamental missing from their understanding of the universe after making the discovery of synchronised galaxies. The finding suggests there may be large scale structures which are unseen and influencing galaxies over billions of miles. It is already well established that nearby galaxies can influence each other with their gravitational push and shove, but it has never been observed on such a large scale.
    Researchers from the Korea Astronomy and Space Science Institute noticed galaxies up to 20 million light-years from each other interacting with each other, which left the experts puzzled.
    The team wrote in the paper published in the Astrophysical Journal: “For this mysterious coherence in large scales, we cautiously suggest a scenario in which it results from a possible relationship between the long-term motion of a large-scale structure and the rotations of galaxies in it.”
    Study lead author Joon Hyeop Lee, an astronomer at the Korea Astronomy and Space Science Institute, told Vice: “This discovery is quite new and unexpected."

    I find it odd that we have believed for "so long" that all matter is neatly organized into galaxies. Less than a hundred years ago we didn't know about galaxies. Then we saw nebulas resolve into galaxies and this Island Universe was well and truly put in its place. Now, again, we're learning that our learning is far from being over.

    One interesting thing I've seen recently is speculation that "dark matter" may be mostly comprised of material from the Big Bang that didn't clump into galaxies. It's just cold junk that floats around like liquid smoke between the relatively few bright lights out there.

    wow...
    "The Earth has inspired many a famous tune — from Michael Jackson's 'Earth Song' to Björk's 'Earth Intruders' — but now the blue planet has a song of its very own.
    Astronomers have recorded for the first time the eerie warbling 'song' sung by the Earth's magnetic field when hit by a storm of charged particles sent from the Sun.
    The 'tune' is a sonic version of the stunning aurora light show that can be seen near the poles when charged particles interact with the Earth's atmosphere.
    The 'song' was made audible by experts from the European Space Agency (ESA), who analysed the magnetic waves produced as these 'solar winds' buffet the Earth.
    They turned the results into audible frequencies, producing an unusual noise they described as being more like 'the sound effects of a science fiction movie than a natural phenomenon.'
    The psychedelic song was identified after the team sent four spacecraft through the so-called 'foreshock' region of the Earth's magnetic field, which faces the Sun and is the first part to be impacted by incoming solar storms."
