Just as important is getting a handle on whether/how our sun is different/"special" when compared to other stars. For all its "violent" behaviour observed here, old Sol is famously calm by stellar standards...

@konradcomrade4845 Год назад

The Ulysses probe found that above the sun's polar regions, there is more fast (and faster) solar wind than over its equator. That was surprising at the time. Which can be explained by the sun's rotation. It makes its photosphere to sink deeper (and get hotter) at the poles, while the photosphere at the equator, due to centrifugal forces is bulging outwards, more. This effect of "hot" poles should be even more prominent at fast rotating stars.

@100vg Год назад

Πολλά από αυτά ήταν ελληνικά για μένα (Much of that was Greek to me), 🤣 but I love getting these reports from you. I'm no Astronomer, but I love space study science and the images we get from it. I love the Hubble Space Telescope images and look forward the new images to come from the various projects. I know the ones from Webb are manipulated, and Hubble's may be, too, but that's because we wouldn't be able to appreciate them as much if they weren't. That's what makes them so beautiful. The Eagle's Nest is a longtime favorite. Thank you, Mr. Christian.

@Lucas72928 Год назад

In my electromagnetism class we were taught that magnetic field lines are always closed, how can there be open lines coming from the Sun? Is that due to interaction with other magnetic fields?

@LaunchPadAstronomy Год назад

You're absolutely correct. Magnetic field lines can never be truly "open" but rather must close at some point. The thing is that in the case of the Sun, their 'open' lines can extend far beyond the corona before returning, or even extend past the heliopause and reconnect with the interstellar magnetic field. It's only in the local frame that we can treat the magnetic fields as either "open" or "closed", but that still leaves plenty of room for switchbacks :)

to my understanding the sun as plasma or ionize gas if vibrating/breathing it will generate magnetic flux just like electrical alternating current in single wire.. if this plasma has kinetic acceleration then it will generate gravity..

@David35687 Год назад

These closed loops are not incredibly common, and therefore they don’t explain the coronal heating anomaly, correct? The fact that several locations in the corona are 200 to 300 times hotter than the surface of the sun is the sun’s greatest anomaly.

It's not "switchback" or whatever word you are using, this is called a Sigmoid and was not observed just recently.

I'm just calling it by the term referenced in the literature. See the links to the papers in the description.

@farmergiles1065 Год назад

I'll bet the phenomenon is not new. It's just a phenomenon that's evaded our notice until now. Interesting phenomenon. But really, how humano-centric can we be in talking about it?

Right, the term "new" is shorthand for "new to us." Nobody seriously thinks the Sun started doing switchbacks all of a sudden :)

I like it how the traffic of probes in the Solar System here is already treated like a daily routine. The speaker has already arrived in a historic period of which I did not know that it has already started, of which I've thought it would start only in a few decades. Alas, my joy concerning this revelation is curbed by a misleading makeup of the imagery shown from 11:14 to 11:15. The Sun has a diameter of just under 1.4 million kilometers. This lets appear the probe in that imagery as coming closer to the Sun than 100,000 km. The distance of seven million kilometers mentioned by the speaker is not shown as being five times the diameter of the Sun, which would have been a great opportunity for images that are both realistic and thrilling.

It would be useful if we delivered the phrase "coronal Mass Ejection" as "coronal MASS Ejection". so it emphasises mass is being ejected instead of it sounding like the whole corona ejected something.

Respectfully, "magnetic field lines" are pure abstractions to help us visualize a continuous vector field. They are no more real than lines of latitude and longitude. They cannot bend and break and do all those other things you describe. I'm not sure why this reification has such a firm hold in solar physics.
