Weird: Out of Nowhere, Something Just Rocked Earth’s Magnetic Field
A GLOBAL MAGNETIC ANOMALY: On June 23rd, Earth’s quiet magnetic field was unexpectedly disturbed by a wave of magnetism that rippled around much of the globe. There was no solar…
Oh noes!!! Government Shutdown Imperils Earth’s Magnetic Field!!!
Guest Ohhhhh Noooo!!! by David Middleton Well… maybe not imperiling Earth’s magnetic field… Just delaying the release of the vital World Magnetic Model… NEWS 09 JANUARY 2019 Earth’s magnetic field…
Our quiet Sun produces “Musical Waves” in Earth’s Magnetic Field
By Dr. Tony Philips This week in Norway, a space weather observatory detected sine waves of exceptional purity rippling through Earth’s polar magnetic field. The waves, which persisted for hours…
With the sun spotless – cracks are forming in Earth's magnetic field
While the sun is completely blank today, and has been for 8 days, some new things are happening in space in the electromagnetic relationship between the sun and the Earth…
#AGU16 Earth’s Magnetic Fields Could Track Ocean Heat, NASA Study Proposes
From the “Thermometers? We don’t need no steenkin thermometers!” department and NASA comes this interesting story. Video follows. As Earth warms, much of the extra heat is stored in the…
Ironing out the mystery of Earth's magnetic field
Scientists directly measure thermal conductivity of iron at planetary core conditions for the first time The earth’s magnetic field has been existing for at least 3.4 billion years thanks to…
A link between the solar magnetic field and weather patterns on Earth may explain our lower than normal severe weather in 2013
From the “science is settled” department comes this new paper that points out a correlation between the Interplanetary Magnetic Field (IMF) and polar jet streams, which drive weather events on…
Changes in Earth's gravity in relation to magnetic field measured
From the Helmholtz Association of German Research Centres Rapid changes in the Earth’s core: The magnetic field and gravity from a satellite perspective Annual to decadal changes in the earth’s…
First measurement of magnetic field in Earth's core
Earth’s internal dynamo generates average field in outer core 50 times that at surface A University of California, Berkeley, geophysicist has made the first-ever measurement of the strength of the…
Earth's Magnetic Field Has Massive Breach – scientists baffled
I know. This sounds like a plot of a 1950’s scifi movie. But it is real. From my view, our localized corner of the solar system is now different than…
What Causes Earth’s Strongest Lightning Known as ‘Superbolts’?
When a storm’s charging zone sits close to the earth’s surface, the resulting “superbolts” can be 1,000 times stronger than regular lightning.
DATA: THE SUN’S MAGNETIC POLES ARE VANISHING
Measurements by spacecraft and ground-based observatories agree that the sun’s north and south magnetic poles are rapidly weakening. This could lead to a complete reversal of the sun’s global magnetic…
The March 1940 Superstorm: Geoelectromagnetic Hazards and Impacts on American Communication and Power Systems
In some places, geoelectric amplitudes induced during the March 1940 storm, Section 12, exceeded American electric-power-industry benchmarks.
Secrets of Sunspots and Solar Magnetic Fields Investigated in NASA Supercomputing Simulations
New results based on simulations out of NASA’s Advanced Supercomputing facility at NASA’s Ames Research Center in California’s Silicon Valley are painting a more complete picture of one of the…
New Sunspot may Hurl Dangerous Solar Flare at Earth
SpaceWeather reports: One of the biggest sunspots in years has just rotated over the sun’s northeastern limb. AR3112 has a mixed-polarity magnetic field that harbors energy for strong X-class solar…
Novel NASA Instrument Sets Sights on Earth-bound Solar Radiation
A very small instrument has a big job ahead of it: measuring all Earth-directed energy coming from the Sun and helping scientists understand how that energy influences our planet’s severe…
Mapping a Magnetic Superstorm: March 1989 Geoelectric Hazards and Impacts on United States Power Systems
Geomagnetically induced currents realized during the magnetic storm of March 1989 caused a blackout in Québec, Canada, and, in the Mid-Atlantic and Northeast United States, they caused operational interference for…
Tipping points in Earths geophysical and biological systems
When a threshold is crossed the physical system responds with positive and negative feedbacks until settling into a new climate state as the perturbation damps out.
New Sun Missions to Help NASA Better Understand Earth-Sun Environment
These missions not only extend the science of our other heliophysics missions—they also provide a unique perspective and a novel approach to understanding the mysteries of our star.
Small Satellite, Big Questions: CuPID CubeSat Will Get New Perspective on Sun-Earth Boundary
The proliferation of small, experimental satellite missions has created more opportunities for students to get involved in hands-on engineering projects.
NASA Missions Make Unprecedented Map of Sun’s Magnetic Field
A major goal of heliophysics – the science of the Sun’s influence on space, including planetary atmospheres – is to predict space weather, which often begins on the Sun but…
Magnetic ‘Highway’ Channels Material Out of Cigar Galaxy
Located 12 million light-years from Earth in the constellation Ursa Major, the Cigar galaxy is undergoing an exceptionally high rate of star formation called a starburst. The star formation is…
