    What moves the sailing stones of Death Valley?
    Sliding, slithering, sailing stone mystery solved, – thankfully.
    EarthSky.org – Posted by Deborah Byrd – November 28, 2023

    “Sailing stones leave a trail in the desert – How could rocks – driven by some unseen force – slide across the ground, leaving behind a trail? That’s what happens at Racetrack Playa, a dry lake bed at Death Valley National Park in California. – – The sailing stones, or sliding stones, of Racetrack Playa have been observed and studied since the early 1900s. It was long thought that strong winds pushed the stones. More fanciful theories involved magnetic fields. And, of course, as is the case in many good mysteries, space aliens were sometimes implicated as well.”

    Kudos and high five, or six if you’ve got them, to EarthSky.org for letting us know if those pesky extraterrestrials are involved.

      Mystery of Purple Lights in Sky Solved

      “The citizen science project, funded by NASA and the National Science Foundation, tracks the aurora borealis through user-submitted reports and tweets. – – – For the first time, scientists have ground and satellite views of STEVE (short for Strong Thermal Emission Velocity Enhancement), a thin purple ribbon of light. Scientists have now learned, despite its ordinary name, that STEVE may be an extraordinary puzzle piece in painting a better picture of how Earth’s magnetic fields function and interact with charged particles in space.”

      P.S. Aren’t acronyms great? LARS = Like A Rolling Stone, or Last American Rock Star, or maybe Lets All Renounce Sugar. Carry on.
