Sunspots It happens down by the surface probably beneath. But what it causes on the surface is quite astonishing. Sunspots are the visible counterparts of magnetic flux tubes. Sunspots come in pairs with opposite magnetic polarity. From cycle to cycle, the polarities of leading and trailing (with respect to the solar rotation) sunspots change from north/south to south/north and back. Sunspots usually appear in groups. In 2001, observations from the Solar and Heliospheric Observatory (SOHO) using sound waves traveling below the Sun’s photosphere (local helioseismology) were used to develop a three-dimensional image of the internal structure below sunspots; these observations show that there is a powerful downdraft underneath each sunspot, forming a rotating vortex that concentrates the magnetic field.
The sunspots often form plasma loops, which are also called Coronal loops. The process feeds the corona with chromospheric plasma and powerful enough to accelerate and therefore heat the plasma from 6000 K to well over 1 MK over the short distance from the chromosphere and transition region to the corona. Coronal loops, Sunspots create this phenomenon from magnetic flux.
https://en.wikipedia.org/wiki/Solar flares “The high magnetic fields in the sunspot-producing active regions also give rise to explosions known as solar flares. When the twisted field lines cross and reconnect, energy explodes outward with a force exceeding that of millions of hydrogen bombs. Temperatures in the outer layer of the sun, known as the corona, typically fall around a few million kelvins. As solar flares push through the corona, they heat its gas to anywhere from 10 to 20 million K, occasionally reaching as high as a hundred million. According to NASA, the energy released in a solar flare “is the equivalent of millions of 100-megaton hydrogen bombs exploding at the same time.” Coronal mass ejections The magnetic field lines that twist up to form solar flares occasionally become so warped that, like rubber bands under tension, they snap and break, then reconnect at other points. The gaps that form no longer hold the sun’s plasma on its surface. Freed, the plasma explodes into space as a coronal mass ejection (CME). It takes several hours for the CME to detach itself from the sun, but once it does, it races away at speeds of up to 1,000 km (more than 7 million miles per hour). The cloud of hot plasma and charged particles may be up to 100 billion kilograms (220 billion pounds) in size. Credit Magnetic storms of the Sun.
The galaxy Arp 220 is home to several giant star clusters—about 10 million solar masses—that are twice as massive as any comparable star cluster in the Milky Way Galaxy. McMaster University’s Christine Wilson is captivated by this turbulent galaxy that provides such a target-rich environment for watching stars form.
A little bit more about Arp 220 and apparently scientists have discovered amino acids there, you will have to excuse the talk of colliding galaxies.
The most important thing about this system is not that is 2 colliding galaxies because this is what it is not, it is more like a growing system creating matter.
Quasi-Stellar Objects (QSO) “we have found two pairs
of QSOs, one pair of objects at almost exactly the same angular distance from Arp 220 with redshifts that differ only by less than and a second pair at distances of 29 z p 0.009 .8 and 43.1,
respectively. As far as the first pair is concerned, the similarity of the redshifts and the fact that they lie along an axis through the nucleus of Arp 220 and are at roughly the same distance in opposite directions makes it highly unlikely that this is an accidental configuration.
The most likely explanation is that all four of these QSOs are physically associated with Arp 220 and have been ejected from it, so the redshifts are largely intrinsic in origin.
Quasistellar objects, or quasars, were defined originally as star-like objects of large redshift. Today,
quasars are considered to be the most luminous members of the general class of objects called active galactic nuclei, or AGNs. Quasars are the brightest objects in the universe
We know about quasars because of observations from telescopes.
They are highly luminous and active, from which grow into active galaxies.
There is a lot of activity going on these quasars, matter formation, star creation.
We google Quasars and get from Wiki
“Quasars or quasi-stellar radio sources are the most energetic of a class of objects called active galactic nuclei (AGN). Quasars are extremely luminous and were first identified as being high redshift sources of electromagnetic energy, including radio waves and visible light, that appeared to be similar to stars, rather than extended sources similar to galaxies. Their spectra contain very broad emission lines, unlike any known from stars, hence the name “quasi-stellar.” Their luminosity can be 100 times greater than that of the Milky Way.”
Which is basically telling us, these things pump out energy !!
Then it all turns pear shaped with the media and Astronomy, they go on to say, as if on the drive for research dollars. “Most quasars were formed approximately 12 billion years ago caused by collisions of galaxies and their central black holes merging to form a supermassive black hole.”
A classic example of this is microquasar IGR J17091-3624. Once again if we look the IGR number up we get, from Wiki a Black hole and you may find in a number of science article they refer to this system as proof of a black hole !
Is there any rational discussion about this system going on ?
Well yes but I suppose it depends how far you want to venture down the rabbit hole. Well it didn’t take me long and I found.
“Microquasar IGR J17091-3624 exhibits faint, quasi-periodical outbursts of the period between 5 and 70 seconds and regular amplitudes, frequently referred to as the
’heartbeat state’. ”
Quasars what are they ?

All of the evidence suggests that these QSOs have been ejected from z p 1.25 Arp 220 and have large intrinsic redshifts.
“The distribution on the sky of clusters of galaxies started to be cataloged about 40 years ago by George Abell and collaborators. The cores of these clusters were predominantly old stellar population E galaxies which were believed to be mostly gas free and inactive. With the advent of X-ray surveys, however, it became evident that many clusters of galaxies were strong X-ray emitters. This evidence for non-equilibrium behavior was not easily explained. In these active properties, however, the clusters joined AGN’s and quasars as the three principal kinds of extragalactic X-ray sources. Evidence then developed that quasars, and now some galaxy clusters were physically associated with much lower redshift galaxies. Surprisingly, the cluster redshifts were sharply peaked at the preferred quasar redshifts of z = .061, .30 etc. (This evidence has been discussed principally in Arp 1997; 1998a; Arp and Russell 2001).”
Well it gives us life from the energy it throws our way, photosynthesis for plants and vitamin D for us.
It has been worshiped throughout the ages.
What do we really know about it ?
A quick google search will tell you hydrogen and helium and a light sprinkling of metals.
Anything that talks about the center of the sun is theory. So forgot about the millions of degrees at the center of the sun, that is speculation. As there has been to date no concrete proof of this.
Let us instead talk about what we do know for a fact about our star.
The surface of the Sun that we typically see from Earth is the photosphere which is a brightly radiating layer of plasma only about 500 km thick. It is analogous to the ‘anode glow’ region of a laboratory gas discharge experiment
The temperature of the surface of the sun fluctuates according to the activity on the surface, but an average temperature of 5,500 degrees C has been obtained for the photosphere. This is not in the millions or even hundreds of thousands. No you heard me 5500 C. Temperatures this hot have been made on earth.
The chromosphere is the innermost atmospheric layer. It is just above the photosphere. Here the temperature begins to rise again, to about 20000 degrees C
The Corona of the sun is hotter still, The corona can get about 2 million degrees C.
“The sun’s photosphere is often mistakenly referred to as the surface of the sun. In reality however, the sun’s photosphere is only a “liquid-like” plasma layer made of neon that covers the actual surface of the sun. That visible layer we see with our eyes is composed of penumbral filaments that are several hundred kilometers deep. This visible neon plasma layer that we call the photosphere, and a thicker, more dense atmospheric layer composed of silicon plasma, entirely covers the actual rocky, calcium ferrite surface layer of the sun. The visible photosphere covers the actual surface of the sun, much as the earth’s oceans cover most of the surface of the earth. In this case the sun’s photosphere is very bright and we cannot see the darker, more rigid surface features below the photosphere without the aid of satellite technology.
The composition and mechanical inner workings of the sun beneath the visible photosphere have remained an enigma for thousands of years. There are a whole host of unexplained phenomena related to the sun’s activities that still baffle gas model theorists to this day because they fail to recognize the existence of an iron alloy transitional layer that rests beneath the visible photosphere. Fortunately a host of new satellites and the field of heliosiesmology are starting to shed new light on this mysterious “stratification subsurface” layer of the sun that is located about 4800km beneath the visible photosphere. In addition, recent studies of solar wind suggest that solar wind also originates on the same transition layer under the photosphere as do the electrically charged coronal loops. NASA’s SOHO satellite and the Trace satellite program have both imaged this transition layer of the sun that sits beneath the photosphere. These 21st century satellites and technologies now enable us to peer behind the outer plasma layers of the chromosphere and photosphere and allow us to study the rocky, calcium ferrite transitional layer with incredible precision.
The running difference imaging technique used by both NASA and Lockheed Martin have revealed to us for the first time that the sun is not simply a ball of hydrogen gas in space; it has a hard and rigid ferrite surface below the visible photosphere
The surface can also be seen in raw satellite images. This close up standard image of the surface layer is provided by Trace using its 171 angstrom filter. This close up image shows remarkable surface detail and also shows a close up view of the solar wind created from the electrical arcs. These arcs create streamers as they travel through the sun’s outer atmosphere of mass separated plasmas.
The same remarkable surface detail is still clearly visible in the transitional region two and half minutes later although the lighting has changed slightly due to changes in the electrical arcs coming from the surface. Unlike in the running difference images, in “standard” close up images we can also see the base of the electrical arcs as they rise off the surface into the silicon plasma to form the familiar coronal loop patterns seen in the upper atmosphere.”

Most of the space within our galaxy is occupied by plasma (rarefied ionized gas) containing electrons (negative charges) and ionized atoms (positive charges). Every charged particle in the plasma has an electric potential energy (voltage) just as every pebble on a mountain has a mechanical potential energy with respect to sea level.
The Sun is at the center of a plasma cell, called the heliosphere, that stretches far out – several times the radius of Pluto. As of 9/9/2012 the radius of this plasma cell has been measured to be greater than 18 billion km or 122 times the distance from the Sun to Earth. These are facts not hypotheses.
The Sun is at a more positive electrical potential (voltage) than is the space plasma surrounding it – probably in the order of several billion volts.
Positive ions leave the Sun and electrons enter the Sun. Both of these flows add to form a net positive current flowing through the Sun (entering at the poles and leaving radially at lower latitudes). This constitutes a plasma discharge analogous in every way (except size) to those that have been observed in electrical plasma laboratories for decades. Because of the Sun’s positive charge (voltage), it acts as the anode in a plasma discharge. As such, it exhibits many of the phenomena observed in earthbound plasma laboratory experiments.
The Solar Wind
Positive ions stream outward from the Sun’s surface and accelerate away, through the corona, for as far as we have been able to measure. It is thought that these particles eventually make up a portion of the cosmic ray flux that permeates the cosmos. The ‘wind’ varies with time and has even been observed to stop completely for a period of a day or two.
A couple of questions I found that were interesting
Dr. David Hathaway, a solar scientist at NASA’s Marshall Space Flight Center,
what determines the frequency of solar activity?
David: The sunspot cycle and solar magnetism.
What makes the out layers of the sun so unstable as to eject flares and cause the coronal loops?
David: It’s all magnetism. The magnetic fields are produced inside the sun by the motions of ionized gases. Those magnetic fields rise thru the surface and can become twisted which results in explosions like flares and coronal mass ejections.
While it can be said “. Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace” Is where the first conception of black holes came from.
However it is relativity and Einstein that really pushed black holes into the forefront of mainstream science.
” He found a new way to describe gravity. It was not a force, as Sir Isaac Newton had proposed, but a consequence of a distortion in space and time, conceived together in his theory as ‘space-time’. According to Einstein, matter and energy exist on a background of space and time. Objects distort the fabric of space-time based on their mass- more massive objects have a greater effect.”
So the thing to remember here is that this is theory. It is not based on empirical science.
Yet the impact these mythical constructs are diverting research into real events by fixing the game.
“While black holes, themselves, are invisible, their presence exerts a powerful gravitational force on nearby gas and stars, causing everything to orbit at tremendous speeds. As the matter nears the event horizon, it accelerates until it approaches the speed of light and in the process acquires tremendous energy. Some of this energy is converted into radiation.”
A black hole is in the middle of our galaxy. A Quasar has a black hole in it. A big star when it dies is said to have a black hole. It continues..
Halton Arp ” No one has ever seen a black hole; they are theoretical objects. The basic idea behind a black hole – that gravity can become infinite and compress a large volume of matter to an infinitesimal point (or ‘singularity’) – is irrational and illogical; nothing finite can ever become infinitely large or small, for these are mathematical abstractions.”:
“Galaxies M87 and NGC 6605 are emitting jets of material and are supposed to have supermassive black holes at their centres. According to D.P., black-hole supporters thought the jets were fed by a doughnut-shaped dust cloud around the M87 black hole and an accretion disc of attracted matter around the NGC 6605 black hole, but observations have failed to find evidence of either.
David Pratt says it is significant that matter is nearly always seen moving away from galactic nuclei, instead of towards them as the black-hole theory requires. This is also true of our own galaxy, and the radiation coming from its centre does not match that expected to come from a black hole. Several scientists have concluded that the centres of active galaxies are regions of matter creation rather than matter destruction. D.P. refers to G. de Purucker’s remarks about laya centres, which energy can flow both into and out of. He adds that every point of space is in a sense a laya centre, and that every entity, every atom, every human, and every celestial body has a laya centre at its core, for every physical form is animated from within outwards.
Mainstream scientists tell us that black holes form by the gravitational collapse of extremely massive stars, and some speculate that large volumes of interstellar gas can collapse into supermassive black holes at the centres of galaxies. During this process, gravity allegedly becomes infinitely strong, crushing matter to an infinitesimal point of infinite density and infinite ‘spacetime curvature’. This ‘singularity’, as it is called, is surrounded by a gravitational field so intense that nothing entering a black hole’s boundary can ever escape, not even light. Theorists predict that black holes can emit extremely tiny amounts of heat radiation, so that a typical black hole will evaporate in about a million trillion trillion trillion trillion trillion years.
As pointed out in ‘Big bang, black holes, and common sense’, the existence of black holes as defined above can be rejected simply on the grounds of logic and common sense. In the real world, nothing finite can become infinite or infinitesimal; nor can the boundless universe originate from an infinitesimal point, as the big-bang theory claims. As for the notion of ‘curved space’, which Einstein invented to ‘explain’ gravity, several scientists, and also G. de Purucker, have dismissed it as a mathematical delusion. Inside a black hole, ‘spacetime’ supposedly becomes so distorted that space becomes time and time becomes space. Aard Bol is silent about all this – which is not surprising, as it’s unlikely that he has found a way to turn the finite into the infinite, or space into time!
Leaving aside the weird theories about what goes on inside a black hole, what evidence is there that such objects exist? Black holes can never be observed directly, so scientists look for indirect evidence of them: namely, their gravitational effects on matter in their vicinity, and radiation coming from their direct environment (attributed to material falling into them). However, as Fred Hoyle and other critically-minded astronomers have noted, the available evidence merely points to the existence of highly condensed aggregates of matter which produce very strong gravitational fields – but these objects generally appear to be undergoing explosive activity rather than swallowing things up.
The black-hole theory has great difficulty explaining why gas is universally seen moving radially outward from galactic nuclei. It insists that matter must first be attracted towards a hypothetical black hole from surrounding space, and some of it may then somehow get flung in the opposite direction. In the previous article, I mentioned several observations showing that the postulated disks and clouds of gas and dust surrounding ‘black holes’ are often missing; this implies that the gas or radiation speeding outwards originates within the central object itself – which would, by definition, be impossible if it were really a black hole. After space-telescope observations in 1995 failed to detect material around hypothetical black holes at the centre of many quasars, the astronomer heading the investigation called the discovery ‘a giant leap backward’; this major problem for the black-hole theory has still not been solved.”
