Scientists think they have finally discovered what makes the Sun’s corona so hot
Using data from Europe’s Solar Orbiter spacecraft, scientists now think they have finally pinpointed the process that causes the Sun’s corona — its atmosphere — to be many times hotter than its surface.
For decades, scientists have been struggling to explain why temperatures in the sun’s outer atmosphere, the corona, reach mind-boggling temperatures of over 1.8 million degrees Fahrenheit (one million degrees Celsius). The sun’s surface has only about 10,000 degrees F (6,000 degrees C), and with the corona farther away from the source of the heat inside the star, the outer atmosphere should, in fact, be cooler.
New observations made by the Europe-led Solar Orbiter spacecraft have now provided hints to what might be behind this mysterious heating. Using images taken by the spacecraft’s Extreme Ultraviolet Imager (EUI), a camera that detects the high-energy extreme ultraviolet light emitted by the sun, scientists have discovered small-scale fast-moving magnetic waves that whirl on the sun’s surface. These fast-oscillating waves produce so much energy, according to latest calculations, that they could explain the coronal heating.
You can read the paper here [pdf]. The results have not yet been confirmed, but if so it will solve one of the space age’s oldest scientific mysteries.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Sol is a cosmic induction cooktop? Amazing.
“what makes the Sun’s corona is so hot”
Cotour: Fixed. Thank you.
Now….might that allow a new type of solar energy to be harvested via Dyson Harrop loops?

“The connection between an object’s ability to absorb and emit energy in the form of electromagnetic radiation—its absorptive and emissive efficiencies—has long been explained by something known as Kirchhoff’s law of thermal radiation. The paper describing the work, “Direct Observation of Kirchhoff Thermal Radiation Law Violation,” appears in the July 24 issue of the journal Nature Photonics.”
“‘Our study shows that it is possible to break the equality of Kirchhoff’s law of thermal radiation with a device placed in a **moderate magnetic field. **The device itself combines a material that has a strong magnetic-field response with a patterned structure that enhances absorption and emission in infrared wavelengths.'”
Magnetics can also be used to stop the next Carrington event—which will happen again (AGW or not)
Unlike aerosols—SPS can be a two-fer…clean energy–and grid protection:

Never bought into the electric universe crap—fusion is real—but there could be links….
