For decades, a few scientists have argued that dark matter — the stuff thought to make up 85 % of the matter in the universe — can not explain a universal pattern in the motions of spiral galaxies such as our own Milky Way.

Finding such a galaxy early in the history of the universe challenges the current understanding of how massive galaxies form and evolve, say researchers.

By studying such a large data set — over 200,000 galaxies in 21 different wavelengths, or colors of light, from ultraviolet to infrared — astronomers compared the energy emissions from galaxies across a wide swath of space and time to read the history of the universe.

But other evidence, such as a controversial «stream» of galaxies that seem to be moving in the same direction, dubbed dark flow, is also poking holes in the uniformity of the universe.

Conroy suspects that violent conditions in the early universe — such as galaxy mergers — shocked and compressed gas and dust in particular areas, creating agglomerations of thousands of stars in particular areas.

Both the COBE ripples and the large - scale clustering of galaxies can be explained by a CDM universe in which 80 per cent of the present mass density is contributed by a cosmological constant, though some cosmologists argue that such theories may not explain the motions of galaxies.

Astronomers expect to find roughly 10 more such systems in the survey, which will provide important insights into the fundamental physics of galaxies as well as how the universe expanded over the last several billion years.

GREEN GALAXIES Galaxies in the early universe emitted lots of green light, such as seen in this nebula (NGC 6826) in the MiGALAXIES Galaxies in the early universe emitted lots of green light, such as seen in this nebula (NGC 6826) in the MiGalaxies in the early universe emitted lots of green light, such as seen in this nebula (NGC 6826) in the Milky Way.

Such supernovae belong to the most energetic and brightest phenomena in the universe and can outshine a whole galaxy for weeks.

The existence of such active galaxies in the nearby universe was first noted by the American astronomer Carl Seyfert more than 70 years ago.

Supermassive black holes in the cores of galaxies are thought to fatten slowly over eons, so finding such a heavyweight so early in the history of the universe is «really pushing it,» he says.

«We can explore such original galaxies in full detail and probe the conditions of the early universe,» said Ignacio Trujillo, of the Instituto de Astrofisica de Canarias at the University of La Laguna, Spain.

Cosmologists typically focus on the large - scale properties of the universe as a whole, such as galaxies and intergalactic medium; while astrophysicists are more interested in testing physical theories of small - to medium - sized objects, such as stars, supernovae and interstellar medium.

When Bjork scaled up the search to include 260,000 such systems in our galaxy's habitable zone, the probes took almost 10 billion years — three - quarters the age of the universe — to explore just 0.4 per cent of the stars (http://arxiv.org/abs/astro-ph?papernum=0701238).

They said CID - 947 could be a precursor of the most extreme, massive systems observed in today's local universe, such as the galaxy NGC 1277 in the Perseus constellation, 220 million light years from the Milky Way.

If all such compact dwarf galaxies are stripped, she argues, then their black holes may also be unexpectedly massive — meaning these behemoths are much more abundant in the universe than previously thought.

The currently favored cosmological galaxy models are based on the idea of hierarchical structure formation: that structures in the universe such as galaxies develop from small «overdensities» to become large - scale objects.

Now the researchers hope that future observations of a large number of distant galaxies using the ALMA telescopes could help unravel how frequently such evolved galaxies occur in this very early epoch of the history of the universe.

Astronomers believe that such collisions between galaxies were common in the early universe when galaxies were closer together.

Because distances between galaxies are so vast today, such mergers were thought to be rare.36 But the Hubble telescope, in its furthest look back in time, has photographed dozens of galaxies in the process of colliding.37 Obviously, galaxies formed quickly in the early, much more compact universe.

Currently, the universe we live in obeys two seemingly incompatible laws — quantum mechanics, which governs the behavior of subatomic particles; and relativity, which describes how clumps of atoms, such as humans, stars and galaxies, behave.

The merging of small galaxies into larger ones is common throughout the universe, but because the shredded galaxies are so faint it has been hard to extract details in three - dimensions about how such mergers proceed.

The galaxy mergers that bring two supermassive black holes close together are considered to be a common process in the universe, so astronomers expect that such binary pairs should be common.

The question astronomers have been asking is whether such starbursts in the early universe were the result of having an overabundant gas supply, or whether galaxies converted gas more efficiently.

Scientists have decoded faint distortions in the patterns of the universe's earliest light to map huge tubelike structures invisible to our eyes - known as filaments - that serve as superhighways for delivering matter to dense hubs such as galaxy clusters.

However, by using computer simulations to allow the dark matter to become a little more interactive with the rest of the material in the universe, such as photons, we can give our cosmic neighborhood a makeover and we see a remarkable reduction in the number of galaxies around us compared with what we originally thought.

A simple thing such as a stroll in the park might seem like something from another universe on the other side of the galaxy to our military single, so distant might it appear, yet so wonderful and alluring.
