on galaxies in our universe, yanking them along in a motion he calls «dark flow.»

on the inhabitants of this small, insignificant planet revolving
in this vast solar system, traveling
in this vast
galaxy, floating through this endless

I can't claim to be providing certainly accurate information

in the early
universe (before inflation went out of control) there were irregularities that gave rise to clumping, from which the first stars and
galaxies originated.

There are hundreds of billions of stars
in our
galaxy, each with planets, that large of a number even if a tiny fraction had an atmosphere and even if a fraction of them had water (as we know it is required, but life may not require it

in our
galaxy, let alone
in the
universe with billions of
galaxies each with billions of stars and trillions of planets.
Carl Sagan claimed that «we live
on an insignificant planet of a humdrum star lost

It means that the earth
on which we live is not the center of the physical
universe, but a comparatively small planet revolving round a very average - sized star, which

universe that our existing telescopes have so far penetrated contains about a hundred million star systems or nebulae, similar to our
galaxy.
by calculating the estimation of how many

By learning about the change that the first stars and
galaxies imposed
on the
universe, Hewitt said, HERA will help scientists figure out if the larger picture — the story — that they've pieced together about the emergence of luminous objects
in the cosmos is correct.
Some research has been done to deduce the chemical makeup of very early
galaxies, based
on observations of very bright, distant
galaxies, or of very old stars that formed
in the early
universe and are still around today, Hewitt said.
Researchers used supernovas, cosmic microwave background radiation and patterns of
galaxy clusters to measure the Hubble constant — the rate at which the
universe expands — but their results were mismatched, Emily Conover reported
in «Debate persists
on cosmic expansion» (SN: 8/6/16, p. 10).
The reionization of hydrogen
in the
universe didn't occur like the flipping
on of a light switch; it wasn't instantaneous and probably didn't happen at the same rate across the cosmos, said Anna Frebel, an assistant professor of physics at MIT who studies stars and
galaxies that formed
in the very early days of the
universe.
His work was very mathematical and computer - intensive, two of my strengths at the time, and we made a lot of progress

The study, published online today
in The Astrophysical Journal Letters, describes how the researchers used the powerful MOSFIRE instrument

galaxy looked like only 670 million years after the big bang.
Based
on measurements of the expansion using Type Ia supernovae, measurements of temperature fluctuations
in the cosmic microwave background, and measurements of the correlation function of

universe has a calculated age of 13.7 ± 0.2 billion years.
A new study based
on observations with the Hubble Space Telescope has shown that the most massive

SALT LAKE CITY —
In the primeval
universe, a violent event roiled a dwarf
galaxy, leaving an indelible mark
on the stars that formed there.
Dwarf
galaxies, amorphous blobs of only tens of millions of stars, were cranking out nearly a third of the new stars
in the
universe from about 8 billion to 10 billion years ago, according to new research posted June 17
on arXiv.org.
Most
galaxies in the
universe revolve around central black holes, which feed voraciously
on galactic gas and dust and spew out radiation.
On Friday at a meeting of the Royal Astronomical Society
in Glasgow, U. K., Bluck will report that the most active supermassive black holes release staggering amounts of radiation during their most energetic periods, which can last hundreds of millions of years — enough, he says, «to strip apart every massive
galaxy in the
universe at least 25 times over.»

on how young, hot stars ionize oxygen
in the early
universe and the effects
on the evolution of
galaxies through time.
Analysis of the newly found quasar shows that a large fraction of the hydrogen
in its immediate surroundings is neutral, indicating that the astronomers have identified a source

on to fully re-ionize the
universe.
In practice, normal and dark matter appear to fill the
universe with a foam - like structure, where
galaxies are located
on the thin walls between bubbles, and are grouped into superclusters.
FIRST BURST A supermassive black hole (illustrated)
in the early
universe suggests some black holes got a head start
on the
galaxies they inhabit.
This is significant, according to the researchers, because many models for what we know about the
universe rely
on galaxies behaving
in a fashion similar to the Milky Way.
Initial fluctuations
in the matter density of the early
universe led to the formation of
galaxies, but these fluctuations must have been small or they would have imprinted themselves
on the microwave background.
Lead scientist Professor Tim Gershon, from The University of Warwick's Department of Physics, explains: «Gravity describes the
universe on a large scale from
galaxies to Newton's falling apple, whilst the electromagnetic interaction is responsible for binding molecules together and also for holding electrons
in orbit around an atom's nucleus.

on stellar explosions
in distant
galaxies gave astronomers their best measurement of how fast the
universe is expanding.
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.
Alternate
universes with larger cosmological constants would prevent
galaxies from coalescing, while those with zero or negative values might quickly collapse a budding cosmos
in on itself.
...
on black holes: They are highly significant: Every
galaxy has one at its center, and they play a dominant role
in the structure of the
universe.
To compute one of the two main simulation runs, over 24,000 processors were used over the course of more than two months to follow the formation of millions of
galaxies in a representative region of the
universe with nearly one billion light - years
on a side.
The cosmic web — the distribution of matter
on the largest scales
in the
universe — has usually been defined through the distribution of
galaxies.
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.
But Hubble went
on to make some of the most important discoveries
in the history of astronomy, from providing the best estimate of the
universe's age to discovering black holes
in the center of
galaxies.
