Dark matter's presence has for decades been inferred from its gravitational effects on large - scale structures such as galaxy clusters, but because it does not interact much with ordinary matter and does not emit or absorb light — hence the «dark» moniker — it has so far proved impossible to observe firsthand.

Because protoclusters are spread out over a much larger area of the sky, they are much harder to find than galaxy clusters.

Spiral galaxies such as the Great Nebula in Andromeda are obvious candidates, but the elliptical galaxies are much older and more highly evolved and could conceivably harbor a large number of extremely advanced civilizations.

Each magnified image makes the galaxy appear as much as 10 times larger and brighter than it would look without the intervening lens.

«It's not where the star formation is, and to see so much gas that far from the star - forming region means there is a large amount of neutral hydrogen around the galaxy,» Neeleman said.

The nursery is 6200 light years from the galaxy's centre and spans 4400 light years, far larger than any in the Milky Way, even though the galaxy itself is much smaller than ours.

Those theories suggest that, since there is much more dark matter in the universe than visible matter, galaxies will form where large concentrations of dark matter (and hence stronger gravity) are present.

Dwarf galaxies are sometimes embedded in a smoothly rotating disk of hydrogen gas that is much larger than the galaxy itself.

In such a model, the visible galaxies ablaze in starlight are like the tip of an iceberg — the visible matter is at the very densest part of much larger dark matter chunks.

This cluster has a diameter of approximately 15 million light years which is not much larger than our Local Group but it contains fifty times the number of galaxies.

Webb's giant sunshield will protect it from stray heat and light, while its large mirror enables it to effectively capture infrared light, bringing us the clearest picture ever of space objects that emit this invisible radiation beyond the red end of the visible spectrum — early galaxies, infant stars, clouds of gas and dust, and much more.

The gas clouds in galaxies are much larger than the stars, so they will very likely hit the clouds in another galaxy when the galaxies collide.

@Amir: Too late too much money is already been spent but you can explain the formation of galaxies and overall large scale structures of the material in the universe.

In 2003, the Anglo - Australian Observatory released a much larger survey («2dF Galaxy Redshift Survey») of over 221,000 galaxies in two slices that extend over 1.5 billion light years in a two - degree field of the sky.

The galaxies are much fainter than the quasars so only the largest telescopes can gather enough light to create a spectrum for those far away galaxies.

NGC 3359 appears to be devouring a much smaller gas rich dwarf galaxy, nicknamed the Little Cub, which contains 10,000 times fewer stars than its larger companion.

«The galaxy we have observed, EGS8p7, which is unusually luminous, may be powered by a population of unusually hot stars, and it may have special properties that enabled it to create a large bubble of ionized hydrogen much earlier than is possible for more typical galaxies at these times,» Sirio Belli, a Caltech graduate student who worked on the project, said, in the statement.

But astronomers also know that much larger, supermassive black holes lie at the heart of large galaxies including the Milky Way, where Sagittarius A * weighs as much as 4 million suns.

Galaxies are much larger systems of...

It may be that the galaxy we have observed, EGSY8p7, which is unusually (intrinsically) luminous, has special properties that enabled it to create a large bubble of ionized hydrogen much earlier than is possible for more typical galaxies at these times,» said Sirio Belli, a Caltech graduate student who helped undertake the key observations.

The amount of oxygen in a galaxy is determined primarily by three factors: how much oxygen comes from large stars that end their lives violently in supernova explosions — a ubiquitous phenomenon in the early Universe, when the rate of stellar births was dramatically higher than the rate in the Universe today; how much of that oxygen gets ejected from the galaxy by so - called «super winds,» which propel oxygen and other interstellar gases out of galaxies at hundreds of thousands of miles per hour; and how much pristine gas enters the galaxy from the intergalactic medium, which doesn't contain much oxygen.
