Hmm Ok won't be told , I know it all type . No room for anything but rote there.
Paul Steinhardt (Princeton cosmology expert)
NGC 524 is a lenticular galaxy. Lenticular galaxies are believed to be an intermediate state in galactic evolution — they are neither elliptical nor spiral. Spirals are middle-aged galaxies with vast, pin wheeling arms that contain millions of stars. Along with these stars are large clouds of gas and dust that, when dense enough, are the nurseries where new stars are born. When all the gas is either depleted or lost into space, the arms gradually fade away and the spiral shape begins to weaken. At the end of this process, what remains is a lenticular galaxy — a bright disc full of old, red stars surrounded by what little gas and dust the galaxy has managed to cling on to.
"One of the key puzzles is how new stars rid themselves of angular momentum: As the material in the cloud contracts under the influence of gravity, slight rotational motions will spin up considerably for the same reason that a twirling skater will spin faster when pulling in her arms. For the developing star, the consequent centrifugal force can stymie further contraction, and so a star needs to find a way to dissipate the effects. Astronomers think that stars develop bipolar jets of material that channel the spinning material into outflows that can escape and allow the contraction to continue. Indeed these outflows, often dramatically narrow and long, are commonly seen. But how early do these flows develop, and how effective are they at enabling the young star to continue its growth?"

https://www.latimes.com/science/sci...nova-gamma-ray-burst-20131120,0,2161505.storyGamma ray bursts are something of the firefly of the astronomy world - very brief but intense radiation events that occur in every reach of the known universe with near daily regularity. They are the highest-energy events since the Big Bang and offer windows into the late stages of different kinds of stars and into the genesis of black holes. But they often are so distant they are hard to analyze.
There is a theoretical limit to the amount of energy that ought to be emitted by such synchrotron radiation, and that limit appears to have been shattered during the event. The apparent anomaly leaves astrophysicists reconsidering their assumptions about the energy sources and internal dynamics of gamma ray bursts.
On a daily basis we are being fed more and more from science media about black holes being just everywhere and it seems obvious to me theyare a fundamental galaxy building block . No black hole , no galaxy.

The other interesting thing is that well established and accepted theories are falling at a rapid rate too

Another prediction of the superluminal model for pulsars is that there should be a component of the pulsar's flux that decays as 1/distance, rather than as the conventional inverse-square law. The effect is in fact a general property of sources that both exceed the speed of their emitted waves and accelerate, and has been known in the field of acoustics since the advent of supersonic aircraft; it results from focusing of the emitted waves in the time domain. In pulsars, the acceleration is centripetal, due to the fact that the superluminal polarization current rotates with the neutron star's magnetic field. Singleton's presentation suggests that this non-spherically-decaying radiation is detected in pulsar observational data.
A little way back I noted the jet from the poles and some discussion and disagreement was had.
This site has a recent xray and radio shot of OUR supermassive black mass Sagittarius A
Thats the one at the center of the milky way

Scientists think jets are produced when some material falling toward the black hole is redirected outward. Since Sgr A* is presently known to be consuming very little material, it is not surprising that the jet appears weak. A jet in the opposite direction is not seen, possibly because of gas or dust blocking the line of sight from Earth or a lack of material to fuel the jet.
Nice: From the Press Release
On the jet issue I would expect to see a jet on the other side equally considering I think it comes from inside and is squeezed out by the supermassive pressures.A jet in the opposite direction is not seen, possibly because of gas or dust blocking the line of sight from Earth or a lack of material to fuel the jet.
Thanks for the entertainment- You took whats called the outside route up the reef and by the looks of the company you had to.
On the Pic I had not seen that . I add it here and ,to be honest, it could be anything, anywhere and at almost anytime these days .Fascinating stuff
