Space Hurricane Seen Above Magnetic North Pole Was Raining Electrons
The first space hurricane ever was spotted in August 2014, consisting of “an eddy of plasma, a type of superhot, charged gas found throughout the solar system,” reports Business Insider. “And instead of rain, this storm brought showers of electrons.” From the report: In August 2014, satellites observed a swirling mass with a quiet center more than 125 miles above the…
‘Earth wind’ may generate water on the moon
Particles carried from Earth’s poles via our planet’s magnetosphere could be interacting with lunar rocks to create small quantities of water on the moon. Source: https://earthsky.org/space/earth-wind-may-generate-water-on-moon…
Magnetic effect without a magnet
Electric current is deflected by a magnetic field—in conducting materials, this leads to the so-called Hall effect. This effect is often used to measure magnetic fields. A surprising discovery has now been made at TU Wien, in collaboration with scientists from the Paul Scherrer Institute (Switzerland), McMater University (Canada), and Rice University (U.S.): an exotic metal made of cerium, bismuth and…
Geomagnetic reversal linked to mass extinction
Scientists believe that a historic reversal of the Earth’s magnetic field may have proven catastrophic. The current orientation of our planet’s magnet… Source: https://www.unexplained-mysteries.com/news/344093/geomagnetic-reversal-linked-to-mass-extinction…
Could Earth’s Reversing Magnetic Poles Accelerate Climate Change?
A team of researchers from Sydney’s University of New South Wales and the South Australian Museum have investigated how the reversal of Earth’s magnetic pole about 42,000 years could have changed earth’s atmosphere. CNN reports: “Using the ancient trees we could measure, and date, the spike in atmospheric radiocarbon levels caused by the collapse of Earth’s magnetic field,” Chris Turney, a…
Upheaval and extinctions linked to magnetic reversal 42,000 years ago
42,000 years ago, a breakdown in Earth’s magnetic field led to environmental catastrophes and mass extinctions. Source: https://earthsky.org/earth/magnetic-field-reversal-42000-years-ago-neanderthal-extinction…
Sounding rocket CLASP2 elucidates solar magnetic field
Cooperative operations between a solar observation satellite and a sounding-rocket telescope have measured the magnetic field strength in the photosphere and chromosphere above an active solar plage region. This is the first time that the magnetic field in the chromosphere has been charted all the way up its top. This finding brings us closer to understanding how energy is transferred between…
Earth’s magnetic field flipped 42,000 years ago, creating a climate ‘disaster’
Earth’s last magnetic flip 42,000 years brought environmental change and extinctions. Could that happen now? Source: https://www.livescience.com/magnetic-flip-42000-years-ago.html
Earth’s magnetic field flipping linked to extinctions 42,000 years ago
Earth’s most recent magnetic pole reversal, called the Laschamp event, has been dated to 42,000 years ago and coincides with extreme weather and the extinction of large mammals Source: https://www.newscientist.com/article/2268520-earths-magnetic-field-flipping-linked-to-extinctions-42000-years-ago/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
