Space.com video: James Webb space telescope view of the Pillars of Creation

Astronomers have discovered a cluster of galaxies merging around a rare red quasar, a "monster" supermassive black hole that is greedily feeding on gas and other material.

An international team of scientists made the surprising discovery as they were using the James Webb Space Telescope (JWST) to stare billions of years back in time. The finding represents an opportunity to observe how early galaxies merged forming the universe as we see it today. The blindingly bright quasar and extremely red quasar, known as SDSS J165202.64+172852.3, is about 11.5 billion years old and one of the most powerful ever seen from a such tremendous distance away, according to the researchers, who describe it as a black hole in formation.

"We think something dramatic is about to happen in these systems," Andrey Vayner, research co-author and an astrophysicist at Johns Hopkins University in Maryland, said in a statement. "The galaxy is at this perfect moment in its lifetime, about to transform and look entirely different in a few billion years."

Einstien solved the gravity question 100 years ago as an effect of matter curving spacetime's direction but were still bent out of shape over quantum gravity. I say forget it. It's probably the same force that gathers dust bunnies together. Quantum gravity may just be electro dynamic as well. That is my simplistic and naieve conclusion.

Some folks believe that dark matter is primordial dark matter stuff that can be tiny atomic size to ultra massive size. A primordial black hole has to be made of different material than visible matter fed black holes since there wasn't enough time to grow to such enormous sizes so soon after the big bang...
they think.
Only one part in a billion of matter remaining from the matter anti matter annihilation survived which is the visible matter we see. What about the 999,999,999 remainder of disintegrated annihilated matter? Much of it is energy but a small amount is the strange debris that might be primordial black hole stuff or dark matter. That dark matter out numbers visible matter by 70 to 90% compared to the small amount of visible matter.
If this sounds familiar congratulations, you understood me the first time around 10 years ago. Of course I could be wrong but thats the way I see it. Of course I can't see dark matter. Some say primoridial black hole stuff is less dense than than normal black hole stuff.

Sorry Mr. Horrible Boss
I can't do that since I have more questions than answers.
For example we should see steller nurseries with Webb but will we see ancient ultra
massive black holes from their hot accretion disks shifted to the red so long ago? They shouldn't be able to exist but we don't know yet.
Black hole spotting is very rare today since...we can't see them.
We can see their accretion disks or jets or gravitational effects on other bodies.
So will we see black holes with the Webb? How old can they be? What will be their composition? Will we find the missing sizes of black holes? We should be able to see stars being born more clearly but there are more questions we do not even know to ask yet. Will we see star grave yards by the name of black holes never seen before?

The first images are now coming back to us, a mosaic of 18 images of the same star seen by the 18 mirror segments. The images will be used to align the mirrors correctly so that future images will be pin-sharp. My understanding of the technicalities is limited but it's enough to get me excited.

Conviviality enhances idea sharing more than a tale of two trolls.
I see that oft repeating formula for thread closure over exploration as an empty bleak waste of time. You would think old people would eventually evolve beyond the 90's 'flaming' behavior. But for familiar reasons some ill intentioned people, the familiar is all they will ever know. What are those familiar reasons? Its as we all know, when people really don't like themselves.
My unrequested advice is to forgive yourself. It is an old panacea like the defintion of the word 'karma' in original Sanscrit -
karma: to take action with a moral choice to bring good into the world.

It is my guess that Elon Musk, using his first principles, would have reasoned that satellites that small would burn-up completely. Small means lighter payload getting them up there, thus more on each shot.

The stronger the gravity the slower time goes.
If near infinite gravity existed at the big bang it could slow time to a stop, a bit like black holes. Also the faster the velocites the more mass grows. PERHAPS TIME WAS STOPPED INSTEAD OF IMPOSSIBLE INFLATION IDEAS.

Type one A super novas come from binary stars when one star is a white dwarf and has a runaway nuke explosion with matter from the other star.
The umbrella galaxy is a red giant and a white dwarf where the white dwarf explodes only partially. Depending on the elderly stars in a binary system, they can do unexpected things. Neutron binary stars warp gravity. Binary black holes combine to make bigger black holes and ripples the universe for billions of light years. Some super massive black holes are mysteriously big at the early universe.
How did they grow ?

The centre of mass of the earth-moon system is 1058 miles inside the earth measured from the surface, whereas the centre of the core is 3958 miles down. I think it would be true to say that all pairs of bodies, in which one appears to be in orbit around the other, follow the rule that they both actually "orbit" around their centre of mass. In the case of the telescope and the point L2, there isn't a centre of mass because L2 hasn't got mass. That's why the wiki article states that the halo "orbit" isn't an orbit in the usual sense. But a physics thickie such as meself is perfectly happy, for sheer convenience, to talk about it as if it was.

https://apod.nasa.gov/apod/image/2202/archives_raquarii.jpg
Explanation: Variable star R Aquarii is actually an interacting binary star system, two stars that seem to have a close symbiotic relationship. Centered in this space-based optical/x-ray composite image it lies about 710 light years away. The intriguing system consists of a cool red giant star and hot, dense white dwarf star in mutual orbit around their common center of mass. With binoculars you can watch as R Aquarii steadily changes its brightness over the course of a year or so. The binary system's visible light is dominated by the red giant, itself a Mira-type long period variable star (Joe). But material in the cool giant star's extended envelope is pulled by gravity onto the surface of the smaller, denser white dwarf (Steve), eventually triggering a thermonuclear explosion, blasting material into space. Astronomers have seen such outbursts over recent decades. Evidence for much older outbursts is seen in these spectacular structures spanning almost a light-year as observed by the Hubble Space Telescope (in red and blue). Data from the Chandra X-ray Observatory (in purple) shows the X-ray glow from shock waves created as a jet from the white dwarf strikes surrounding material. When a collision is enevitable it is not expected to form a black hole.

Ho ho ho. Not all moons truly orbit around their planet, it depends on their relative masses. They orbit around the centre of mass. Which is never in the centre of the larger body (eg Earth) and in some cases the focus is outside the larger body, both orbit around nothing. Oooer.

One thing the video shows, it that the JWST's trajectory is not normal to the plane of the Earth but at 33º off 90.

And the narrator does mention that all the planets affect the orbit (and moons). Adding to normal corrections every 21 days to maintain an elliptical orbit. I actually got into the video after the first 30 seconds.

I've set it up in the driveway with the porch lights off. I can get into an area that is away from the streetlights (the back yard would be better but the dogs are a hazard to the tripod unless I lock them up.) I don't have a connection for the camera on the telescope, though that would be nice. I have also set up the Canon camera with the long lens on a tripod to catch lunar events.
