From a small blue planet, tiny conscious parts of our universe have begun gazing out into the cosmos with telescopes, repeatedly discovering that everything they thought existed is merely a small part of something grander: a solar system, a galaxy and a universe with over a hundred billion other galaxies arranged into an elaborate pattern of groups, clusters and superclusters.

Andrew Gould of the Institute for Advanced Study in Princeton, New Jersey, analysed a small cluster of galaxies called Eridanus A.

The largest clumps of matter in the universe had an initial angular momentum — and these clumps broke up into ever smaller clumps, forming smaller clusters of galaxies, groups of galaxies, individual galaxies, solar systems within galaxies and ultimately, individual stars and planets.

To make a clear distinction between galaxies and globular clusters, astronomers decided that true galaxies, no matter how small, must be massive enough to hold on to heavy elements.

Small galaxy groups are about 1000 times more common than large clusters, so there should be many more Bullet - like groups.

Thus, in a 1991 account of new data with important implications for the mystery of the origin of galaxies, we are helpfully informed that the moral of the data is «do not use O / Fe in a small sample of stars», and that the data leaves a puzzle about globular clusters «with very different horizontal branch (post-main sequence) morphologies».

Elsewhere in the image, we can look into Orion A's dark molecular clouds and spot many hidden treasures, including discs of material that could give birth to new stars (pre-stellar discs), nebulosity associated with newly - born stars (Herbig - Haro objects), smaller star clusters and even galaxy clusters lying far beyond the Milky Way.

Up until recently, those seeking the exotica of the universe — dark matter as well as dark energy — focused on the very largest scales (galaxy clusters and up) and on comparatively small ones (a single galaxy).

The stretching explanation says that during creation week, galaxies, galaxy clusters, and stars with heavy elements formed in a much smaller universe.

This is the deepest large mm - wave dataset in existence and has already led to many groundbreaking science results, including the first galaxy clusters detected through their Sunyaev - Zel «dovich effect signature, the most sensitive measurement yet of the small - scale CMB power spectrum, and the discovery of a population of ultra-bright, high - redshift, star - forming galaxies.

The «bottom - up» model builds galaxies from the merging of smaller clumps about the size of a million solar masses (the sizes of the globular clusters).

Apparently, despite its comparatively small size, this dwarf elliptical galaxy has also a remarkable system of 8 globular clusters in a halo around it.

It is not possible to get a good photograph of the entire Virgo cluster because the galaxies are rather faint and small objects scattered across 15 degrees of the sky.

[16] Like Mayall II, Omega Centauri has a range of metallicities and stellar ages that suggests that it did not all form at once (as globular clusters are thought to form) and may in fact be the remainder of the core of a smaller galaxy long since incorporated into the Milky Way.

My colleagues and I were using the Echellette Spectrograph and Imager (ESI) instrument, which looks at faint objects in the visible wavelengths, to study star clusters and small galaxies.

The inset shows a small cluster of stars embedded in the stream, which marks the center of the disrupted galaxy.

Their relative velocities, as inferred by the redshifts of their light, are so high that these clusters should be flying apart, because each cluster's visible mass is much too small to hold its galaxies together gravitationally.a Because galaxies within clusters are so close together, they have not been flying apart for very long.

The fact that globular clusters have these small black holes implies that they are excellent candidates to act as the seeds for the supermassive black holes that lurk in the centers of nearly all galaxies.
