A New Phenomena Observed at the Sun: Electric Star

Now It's a Triangle on the Sun
It's called a coronal hole. See video:

This one may be better, since it just shows the image at the various frequencies with no commentary:

This one may be even better, since it compares 3 at a time and has pretty good music.

* What Next?
* By the way, the video says some images were suspiciously suppressed.
* Well, here's an image, but the videos show the image in various light frequencies:

Now It's a Triangle on the Sun

It's not a triangle - it's a scorch mark from the "Iron" Sun.

The brain is very good at interpolating shapes. It's not clear whether the band of material through the middle is obscuring an underlying triangle (like clouds), or whether the triangle is simply an illusion made by a "C" (or maybe "G", "f", or a glove puppet, depending on whether you squint) shaped bit at the top and a fat "w" bit (or maybe Winnie the Pooh lying on his back, head to the left) at the bottom.

The straight edges and the sharp corner at the bottom-left are definitely intriguing, regardless of whether there is really a triangle there or not.

found this by accident..are these the coronal holes?

Perhaps the Sun's most remarkable magnetic features are the coronal transients. These objects were discovered by the seventh Orbiting Solar Observatory satellite (OSO-7) and later were studied intensively by Skylab. A typical transient begins as a gigantic bubble that appears near the solar surface and flies out through the corona at a velocity of hundreds of kilometers per second. These transients usually are caused by solar flares or by the eruption of a type of solar prominence known as a cool loop. The bubbles, consisting of high temperature plasma, carry along magnetic fields from the lower corona and disrupt the upper corona as they expand outward.

The majority of the loops are arranged in long rows or arcades, which frequently cover a large fraction of the surface.

Nice, like mitochondria.

Great link Sparko.

The temperatures and densities of coronal holes are much lower than those of other parts of the corona. Investigations show that in the holes, the magnetic field has no loops, but extends directly out into the solar wind. [or in?] We do not yet know how and why coronal holes form, but we do know that they are a major source of the solar wind. Two apparently permanent coronal holes exist at the north and south poles of the Sun, and it may be that much of the solar wind that leaves the Sun originates in these two polar coronal holes

Bubbles and holes. Are we seeing a pattern here?

Parker explained, that its gas is constantly evaporating away from the Sun at supersonic speed.

Either they need to take another look at solar transmissions, or we need to take another look at terrestrial evaporation...

Overall, the site definitely shows NASA getting electricity, and much better illumination for the money.

Why Won't the Supernova Explode?

Many of the best computer models of supernovas fail to produce an explosion. At the end of the simulation, gravity wins the day and the star simply collapses.
Clearly, physicists are missing something.

Perhaps an electric circuit ??


"We don't fully understand how supernovas of massive stars work yet," says Fiona Harrison, an astrophysicist at the California Institute of Technology.
