galaxy

Since than, the expansion of the universe has pushed galaxies farther apart.

The new galaxy is of a type known as a dwarf galaxy because it is faint and small - unlike the Milky Way and Andromeda galaxies, the two local giants.

STREAMING DATA Several teams of astronomers contributed to the discoveries, but all used the same raw data--the Sloan Digital Sky Survey, a map of stars and galaxies that covers one-fourth of the sky (SN: 2/4/06, p.

We know that at some point in the early history of the universe, galaxies came together and formed out of a primordial soup.

Fruchter and his colleagues compared the character of the burst galaxies with the homes of 16 core-collapse supernovas, explosions of massive stars that leave behind either a neutron star or a black hole.

But they expected that more detailed analysis of these pictures and further Hubble photography of the same region, combined with observations by some of the world's most powerful ground-based telescopes, should lead to a better understanding of how galaxies form and evolve and when these processes began in the young universe.

The new findings raise the question: Did the universe have enough time during its first 800 million years for infant galaxies to have merged into mature-looking behemoths?

The modelers laid onto this canvas of dark matter a rough approximation of some of the messy and complex interactions between galaxies, such as the eruption of supernova explosions and the trajectories of powerful intergalactic winds.

On cosmic size scales ranging from individual galaxies to the whole shebang, the distribution of dark matter provides clues about this substance's nature and past.

Meanwhile, images of a protocluster from an era about 2 billion years later reveal a considerable number of mature-looking galaxies that had already formed large populations of stars.

If Robert Minchin of Cardiff University in Wales and his colleagues are right, they have found the first member of a population of galaxies that theorists have proposed but observers had never seen.

David Schiminovich stared at a gallery of spiral galaxies as though he had never seen anything like them before.

Although he didn't get the faculty position he sought, he may have gotten something better: a clue that led him to uncover what may be one of the most telling relationships between supermassive black holes and the galaxies in which they reside.
