The upper atmosphere of the Sun is dominated by plasma filled magnetic loops (coronal loops) whose temperature and pressure vary over a wide range. The appearance of coronal loops follows the emergence of magnetic flux, which is generated by dynamo processes inside the Sun. Emerging flux regions (EFRs) appear when magnetic flux bundles emerge from the solar interior through the photosphere and into the upper atmosphere (chromosphere and the corona). The characteristic feature of EFR is the Ω-shaped loops (created by the magnetic buoyancy/Parker instability), they appear as developing bipolar sunspots in magnetograms, and as arch filament systems in Hα. EFRs interact with pre-existing magnetic fields in the corona and produce small flares (plasma heating) and collimated plasma jets. The GIFs above show multiple energetic jets in three different wavelengths. The light has been colorized in red,
green and blue, corresponding to three coronal temperature regimes ranging from ~0.8Mk to 2MK.
This is a slow motion video clip from the Solar Dynamics Observatory (SDO) spacecraft - currently staring at the sun from Earth’s orbit. This wavelength is set to see gas in the sun’s Corona - the big opening you see is a coronal hole, opened up by the sun’s tangled magnetic field.
That’s the title of a paper published in Scientific Reports this last week. The lead author, Maurizo Mattesini, a geophysicist from Madrid, proposes a new model for the make-up of Earth’s inner core. The paper title is captivating, but its explanation for the core’s structure is complicated.
The inner core is known to be formed of crystalline iron, but the exact atomic arrangement of the iron is uncertain, and remains an enigmatic puzzle in the most inaccessible part of our planet.
The Swirling Core of the Crab Nebula : At the core of the Crab Nebula lies a city-sized, magnetized neutron star spinning 30 times a second. Known as the Crab Pulsar, its actually the rightmost of two bright stars, just below a central swirl in this stunning Hubble snapshot of the nebulas core. Some three light-years across, the spectacular picture frames the glowing gas, cavities and swirling filaments bathed in an eerie blue light. The blue glow is visible radiation given off by electrons spiraling in a strong magnetic field at nearly the speed of light. Like a cosmic dynamo the pulsar powers the emission from the nebula, driving a shock wave through surrounding material and accelerating the spiraling electrons. With more mass than the Sun and the density of an atomic nucleus, the spinning pulsar is the collapsed core of a massive star that exploded. The Crab Nebula is the expanding remnant of the stars outer layers. The supernova explosion was witnessed on planet Earth in the year 1054. via NASA

Mostly Mute Monday: Stunning Pictures Of The Milky Way’s Magnetic Field
“From the light’s polarization, we can reconstruct the galaxy’s magnetic field. And by superimposing it over the foreground emission map, we can see for the first time how our galaxy’s structure and magnetic field are interrelated. What we found was an intricate relationship between dust grains — the precursors to stars – and the giant magnetic structures we find, some of which extend for over a thousand light years in diameter.”
If you want to view the Milky Way in all its true splendor, you need to go beyond visible light, as the cosmic dust that gives rise to new stars also absorbs visible light, robbing us of a view of our galaxy. But those other wavelengths that are more transparent to the dust — infrared and microwave — are absorbed by Earth’s atmosphere. If we want to see what’s going on, we’ve got to go to space. With nine different frequency maps covering the entire sky, the ESA’s Planck satellite not only can determine what’s through that dust, but it can measure the effects of the Milky Way’s magnetic field due to the polarization of light, showing the future of star birth in our own galaxy.
The Morphogenic Field is a term we use to describe the field of energy around the body. It is an extension of the electrical energy of the nervous system. The brain is an electrical generator with its own field of energy that extends away from the physical body. Many cultures and disciplines recognize this field and give it other names. When people discuss auras, chakras, life force or chi, they are possibly talking about this same energy field.
