Now that I have a new home on solarsystem.social, here's a new #introduction!

I am a #planetary scientist working at the Institut de Physique du Globe de Paris (#IPGP) in France. My research uses the #gravity field, #topography, and #MagneticField of the planets to decipher their internal structure and geologic evolution. My favorite terrestrial body is the #Moon, but I also work with #Mercury, #Venus, and #Mars. Soon I will need to learn about #Psyche and the icy satellites of #Jupiter!

For this week’s #HumansOfCIRES, meet Rick Saltus, CIRES/NOAA NCEI senior research scientist. Rick makes maps & models of the Earth’s #MagneticField, and when he was in Antarctica for work, he spent some quality time with Adélie #penguins!

Earth's Magnetic Field Booms Like a Drum, But No One Can Hear It

You may not be able to hear it, but Earth's magnetic shield booms like a drum when it's bombarded by strong impulses, including those from solar wind, a new study finds.

By Laura Geggel, July 06, 2022

"Every time an impulse strikes the shield's outer boundary — a region known as the magnetopause — jolts ripple through its surface and then are reflected back once they reach the magnetic poles, just like the face of a drum ripples as a percussionist beats it.

"Movements in the magnetopause can impact the flow of energy within Earth's space environment, Archer noted. For instance, the magnetopause can be impacted by solar wind, as well as charged particles in the form of plasma that blow off the sun. These interactions with the magnetopause, in turn, have the potential to damage technology, including power grids and GPS devices."

"Our experimental evidence suggests something extraordinary: a bird’s compass relies on subtle, fundamentally quantum effects in short-lived molecular fragments, known as radical pairs, formed photochemically in its eyes. That is, the creatures appear to be able to “see” Earth’s magnetic field lines and use that information to chart a course between their breeding and wintering grounds."

How Crazy Magnetic Fields Drive the Sun Mad

by Paul M. Sutter

Solar coronal jets are fast moving plumes of plasma that erupt suddenly from the polar regions of the Sun. Astronomers believe that these help heat up the solar corona, but the physics behind the formation of these jets is poorly understood.

How do Maxwell's equations predict that the speed of light is constant?🤔 (photo credit: Fermat's Library)

Maxwell's equations, a set of coupled partial differential equations (PDEs), describe the behaviour of electric and magnetic fields and predict that the speed of light is constant in all reference frames, which is a fundamental principle of the theory of relativity. #Electromagnetism #Relativity #SpeedOfLight #LightSpeed #Light #ElectricField #MagneticField #PDEs #Maxwell #CoupledPDEs
