«The work is ongoing, but what we're able to say now is that galaxies we are seeing at great distances are as strongly clustered in the early universe as they are today,» says Steidel, who is at the California Institute of Technology in Pasadena.»

LRIS also records the spectra of up to 50 objects simultaneously, especially useful for studies of clusters of galaxies in the most distant reaches, and earliest times, of the universe.

Hubble's latest discovery of 250 faint galaxies — formed 600 million to 900 million years after the Big Bang — in the early universe using three galaxy clusters to magnify the light given off by these distant objects.

At some point in the last few billion years, dark energy became dominant in the universe and thus prevented more galaxies and clusters of galaxies from forming.

The nature of dark matter — which physicists describe as the invisible component or so - called «missing mass» in the universe that would explain the faster - than - expected spins of galaxies, and their motion in clusters observed across the universe — has eluded scientists since its existence was deduced through calculations by Swiss astronomer Fritz Zwicky in 1933.

This phenomenon is what makes NGC 4696 stand out from among the other members of the Centaurus cluster, making it one of the biggest and brightest galaxies in the observable universe.

How did galaxies — many clusters of billions of stars — become commonplace in the universe?

Galaxies are not scattered randomly throughout the universe, but are often found in «clusters,» which are in turn parts of larger groupings called «super-clusters.»

When astronomers Margaret Geller and Emilio E. Falco plotted the positions of galaxies and galactic clusters in the universe, it became clear that galactic clusters and superclusters are not randomly distributed.

«Not only will we learn about the formation of the black holes, but these new data from Hubble help us connect globular clusters to galaxies, providing information on one of the most important unsolved problems in astronomy today: how galaxy structure forms in the universe,» adds Michael Rich of the University of California, Los Angeles (UCLA).

Galaxy clusters are commonly observed in the present - day universe and contain some of the oldest and most massive galaxies known.

By studying reionization, we can learn a great deal about the process of structure formation in the universe, and find the evolutionary links between the remarkably smooth matter distribution at early times revealed by CMB studies, and the highly structured universe of galaxies and clusters of galaxies at redshifts of 6 and below.

It will be used for many different types of astronomical studies ranging from detailed imaging of galaxy clusters in the early universe to mapping areas of star formation in our own Galaxy.

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.

Some of the new results included deeper understandings of galaxies in the distant universe, more complete pictures of the massive galaxy clusters, and the searches for exploding massive stars, called supernovae.

Gravitational lensing probes the distribution of matter in galaxies and clusters of galaxies, as well as enables observations of the distant universe.

In an effort to learn more about dark matter, astronomers observed how galaxy clusters collide with each other — an event that could hold clues about the mysterious invisible matter that makes up most of the mass of the universe.

The first map of dark matter in a major part of the universe shows that clusters of galaxies form at the increasingly clumpy intersections of dark matter filaments over time (more).

Dan P. Marrone is interested in galaxy clusters, galaxy formation in the early universe, and the physics of the supermassive black hole in our galaxy, Sagittarius A *.
