A stellar explosion has smashed the record for most distant object in the known universe.
The gamma-ray burst came from about 13 billion light-years away, and represents a relic from when the universe was just 630 million years old.
"It easily surpassed the most distant galaxies and quasars," said Edo Berger, an astrophysicist at Harvard University and a leading member of the team that first demonstrated the burst's origin. "In fact, it showed that we can use these spectacular events to pinpoint the first generation of stars and galaxies."
"The burst most likely arose from the explosion of a massive star," said Derek Fox, an astrophysicist at Penn State University. "We're seeing the demise of a star — and probably the birth of a black hole — in one of the universe's earliest stellar generations."
Gamma-ray bursts mark the dying explosion of large stars that have run out of fuel. The collapsing star cores form either black holes or neutron stars that create an intense burst of high-energy gamma-rays and form some of the brightest explosions in the early universe.
A light-year is the distance that light can travel in a year, or about 6 trillion miles (10 trillion kilometers). So astronomers are seeing this particular burst as it existed 13 billion years ago, because the light took that long to reach Earth observers.
NASA's Swift satellite first detected the ten-second-long gamma-ray burst in the early morning on April 23, and quickly swung about to point its Ultraviolet/Optical and X-Ray telescopes.

NGC 7049 has far fewer such clusters than other similar giant galaxies in very big, rich groups. This indicates to astronomers how the surrounding environment influenced the formation of galaxy halos in the early universe.
I’m just marking this thread in hopes of seeing an answer to your question.
*******************************EXCERPT***************************
Working in these observatories he has made becoming classical "the Catalogue of Peculiar Galaxies" ("Arp's Catalogue" or "Atlas of Peculiar Galaxies of Arp"), where information on galaxies distinguished in "abnormality" that is diversion from usual spiral structure are gathered. In notations and references these galaxies have name of Arp + catalogue number.
At the begining of the scientific activity Dr. Arp was engaged in search of novae in М31 under leading of Edwin Hubble.
In 1983 he was invited to staff of Max Planck Astrophysical institute in Munich.
*********************************EXCERPT***************************************
One of major astronomical discovery of Dr. Arp is that the quasars or, in another words, quasi-stellar objects (QSO) are local objects ejected from the core of active galactic nuclei (AGN). The theory was originally proposed in the 1960s as an alternative to Maarten Schmidt's explanation for QSOs, which stated that they were very distant galaxies that appeared to be highly redshifted because of the expansion of the universe [1]. The implication of the hypothesis was that most of the observed redshift of these QSOs must have a non-cosmological or "intrinsic" origin. Arp has suggested that the QSO emission may instead be ejecta from active galactic nuclei. Nearby galaxies with both strong radio emission and peculiar morphologies, particularly M87 and Centaurus A, appeared to support Arp's hypothesis [2]. In his books, Arp has provided his reasons for believing that the Big Bang theory itself is wrong, citing his research into QSOs. Instead, Arp supports the redshift quantization theory for describing the redshifts of galaxies [3].
Since Arp originally proposed his theories in the 1960s, however, telescopes and astronomical instrumentation have advanced greatly; the Hubble Space Telescope was launched, multiple 8-10 meter telescopes (such as those at Keck Observatory) have become operational, and detectors such as CCDs are now more widely used. These new telescopes and new instrumentation have been used to examine QSOs further. QSOs are now generally accepted to be very distant galaxies with high redshifts. Moreover, many objects that are high-redshift counterparts to normal nearby galaxies have been identified in many imaging surveys, most notably the Hubble Deep Field[4]. Moreover, the spectra of the high-redshift galaxies, as seen from X-ray to radio wavelengths, match the spectra of nearby galaxies (particularly galaxies with high levels of star formation activity but also galaxies with normal or extinguished star formation activity) when corrected for redshift effects.[5 - 7]
Nonetheless, Arp has not wavered from his stand against the Big Bang and still publishes articles stating his contrary view in both popular and scientific literature, frequently collaborating with Geoffrey Burbidge and Margaret Burbidge.[8]

Basically the answer is that likely there is no need to infer ‘Dark energy’ or ‘dark matter’ because the big bang theory is wrong. Am I right?
So what prevailing theory best explains these high redshift QSOs?

# When confronted with =in your face evidence' such as the image of a high redshifted QSO in front of a more distant, low redshifted galaxy, they resort to arguments (usually involving math or statistics) to disprove – or at least make you doubt – what your eyes are telling you. The old Groucho Marx line comes to mind: “Who you gonna believe? Me? Or your lying eyes?”

Welcome, dear visitor
The four forces of physics,
Two of these four forces act in the atomic core. One of them UNIFIES and holds matter together in the core (e.g. via fusion), the other force SEPARATES parts of the atomic core. It produces the radioactivity of e.g. uranium and thorium (table). The other two forces of these four forces act in the infinite space. One of them - gravity - UNIFIES and holds matter together e.g. it forms stars from huge clouds. It holds together stars, solar systems, binary stars, galaxies, clusters. The other force - the electric force - SEPARATES matter of celestial bodies and repulses winds, loops, flares and light years-long jets. The electrically ejected matter is formed to filaments via pinch effect. (see jets of Crab pulsar)

He is working with other astronomers on the question whether the red shifts in the spectrum of quasars are due to the general expansion of the universe.

I.E.....that the red shift in the spectra actually DOES NOT Mean Emitting object is FAR AWAY>>>
