and neutron stars may explain the creation of transient supernovae explosions that tend to occur far away from host galaxies. ur paper examines so-called calcium-rich transientssays Joseph Lyman from the University of Warwick. hese are luminous explosions
For example if you look at a galaxy you expect any explosions to roughly be in line with the underlying light you see from that galaxy

alcium-rich transients observed to date can be seen tens of thousands of parsecs away from any potential host galaxy with a third of these events at least 65 thousand light years from a potential host galaxy.
These are seen also often to explode in remote locations with no coincident galaxy detected. SGRBS are understood to occur
hat we therefore propose is these are systems that have been ejected from their galaxy. A good candidate in this scenario is a white dwarf and a neutron star in a binary system.
The mechanism of the supernova explosion causes the neutron star to be kicked to very high velocities (100s of km/s). This high velocity system can then escape its galaxy

#Densest galaxy is jam-packed with stars Michigan State university right Original Studyposted by Tom Oswald-Michigan State on September 25 2013 Astronomers have discovered the densest galaxy in the nearby universe.
Now imagine as many as 10000 of our suns crammed into that relatively small space. his galaxy is more massive than any ultra-compact drawfs of comparable sizesays Jay Strader assistant professor of physics
and astronomy at Michigan State university nd is arguably the densest galaxy known in the local universe. s detailed in the recent edition of the publication Astrophysical Journal Letters the ultra-compact dwarf galaxy was found in near
the massive elliptical galaxy NGC 4649 also called M60 about 54 million light years from Earth.
What makes this galaxy dubbed M60-UCD1 so remarkable is that about half of its mass is found within a radius of only about 80 light years.
This would make the density of stars about 15000 times greater than that found in Earth's neighborhood in the Milky way. raveling from one star to another would be a lot easier in M60-UCD1 than it is in our galaxystrader says. ince the stars are so much closer in this galaxy
it would take just a fraction of the time. he discovery of ultra-compact galaxies is relatively newâ##only within the past 10 years or so.
but assumed they were either single stars or very-distant galaxies. Another intriguing aspect of this galaxy is the presence of a bright X-ray source in its center.
One explanation for this is a giant black hole weighing in at some 10 million times the mass of our sun. Astronomers are trying to determine
or if they are galaxies that get smaller because they have ripped stars away from them.
The possible massive black hole combined with the high galaxy mass and sun-like levels of elements found in the stars favor the latter idea.
A giant black hole at the center of M60-UCD1 helps tip the scales against the scenario where this galaxy was once a star cluster
The galaxy was discovered using NASA's Hubble space telescope. Follow-up observations were done with NASA's Chandra X-ray Observatory
In addition this mechanism could be used to describe other large spinning astronomical bodies with large-scale magnetic fields such as galaxies.

#Rainbow galaxies reveal why cosmos is full of spirals (Image: ALMA (ESO/NAOJ/NRAO)/ SMA/CARMA/IRAM/J. Ueda et al.
Each entry in this visual catalogue of psychedelic pictures captures a violent collision of galaxies revealing for the first time how galaxies like the Milky way form.
These images show the carbon monoxide gas detected in neighbouring galaxies 40 to 600 million light years from Earth in their final stages of merging.
Out of 37 galaxies observed these 30 all show gas rotating around the centre of the galaxy meaning they are disc galaxies in the making.
For the first time there is observational evidence for merging galaxies that could result in disc galaxies. This is a large and unexpected step towards understanding the mystery of the birth of disc galaxies says Junko Ueda from the Japan Society for the Promotion of Science.
Ueda and her team made the observations using data from the ALMA radio telescope. Computer simulations suggested that
when galaxies merge they usually form a single blob-shaped galaxy classed as elliptical. However most of the galaxies in the universe are shaped pancake disc galaxies such as lenticular galaxies and our own spiral Milky way.
As this rogues'gallery of galactic mergers shows a disc-shaped offspring is a common result of a collision.

A new project proposing that galaxy-spanning alien civilisations should generate detectable heat has turned up a few dozen galaxies that hold promise as harbours for life.
A galaxy should emit about 10 per cent of its light in the mid-infrared range says team leader Jason Wright at Pennsylvania State university.
though it could also be a sign of more prosaic processes such as rapid star formation or an actively feeding black hole at the galaxy's centre.
The team's preliminary survey suggests that such galaxies are rare but they are out there.
We have found several dozen galaxies giving out a superlative amount of mid-infrared light says Wright.
Could that mean we have already found alien civilisations that have spread across galaxies? If by'found them'you mean that WISE detected the waste heat from them then yes that's right
and galaxies that raised the infrared flag in the WISE survey and figure out if there are more ordinary processes at work.
and galaxies he says. Like our exoplanet search and using rovers to look for microbes on Mars this search for extraterrestrial life is driving useful science.
This shows more than ever that our solar system is not the paradigm in our galaxy says Beaulieu.
It is the first to produce realistic-looking galaxies by the thousands and a triumph for our current understanding of the history of the universe.
If you take 40000 galaxies from the simulation and compare them to 40000 real galaxies you would have a very hard time distinguishing them says one of the simulation's creators Mark Vogelsberger of the Massachusetts institute of technology.
This tells you that our understanding of galaxy evolution is so complete now that we can make models that predict a universe that just looks like ours.
Previous simulations had focused on the properties of individual galaxies or on the weblike scaffold of dark matter that connects groups of galaxies.
Recent advances in supercomputing and a fresh computational approach let the recent simulation called Illustris do both at once.
Our main goal was to have a statistical sample of galaxies but also be able to say something about the characteristics of each galaxy says Vogelsberger.
He and his colleagues modelled a cube of space with sides that stretched to 347 million light years a fraction of the size of the observable universe today.
They divided it up into 12 billion smaller units and used equations that describe ordinary matter's behaviour in cosmic structures to calculate what should happen in each unit.
The code also managed to reproduce different types of galaxies including spiral galaxies like the Milky way and blob-shaped elliptical galaxies.
For instance small galaxies in the simulation produced stars too early so they appeared older than we observe them to be today.

The more we can get at these processes by trying to make realistic galaxies and seeing what works and
and distant galaxy have created together a cosmic magnifying glass that could improve our understanding of the universe's expansion and dark matter.
For example the gravity from a massive object like a galaxy can magnify light from another object like a supernova bending its light waves
its light is being lensed by a galaxy in front of it. The supernova PS1-10afx was discovered in 2010 using the Pan starrs telescope in Hawaii.
but nobody could see an intervening galaxy that could be doing the job. There were good data taken before during
Now his team has found a galaxy full of dim old stars that was hard to see against the bright background of the galaxy holding the supernova.
And that in turn may depend on the galaxy's dark matter content and distribution since massive dark matter halos are thought to cocoon galaxies making up most of a galaxy's mass.
We have these numerical simulations of dark matter that make pretty strong predictions of what dark matter halos should look like Schmidt says.
So if you could get a really good measurement of how dark matter is distributed within a bunch of galaxies one can essentially test the dark matter model better than we can at present.
because no thorough measurements have yet been made of how much polarised light the dust in our galaxy produces.

Our solar system has a tail reminiscent of a four-leaf clover according to new observations of the plasma bubble that shields the solar system from the rest of the galaxy.

Researchers say they've detected a supermassive black hole at the center of a newly found galaxy that's far bigger than current theories allow.
The galaxy, with the very clunky name of SAGE0536AGN, was discovered with NASA's Spitzer space telescope. Scientists think it's about 9 billion years old.
The research team says it confirmed a black hole in the galaxy's center by measuring the speed of the gas swirling around it.
Black holes heading for'massive collision,'says astronomer What they found blew away their theories about how galaxies evolve.
The data indicated the black hole is 30 times larger than expected for this size of galaxy, according to a press release from the Royal Astronomical Society."
"Galaxies have a vast mass, and so do the black holes in their cores. This one though is really too big for its boots--it simply shouldn't be possible for it to be said so large
Researchers say it could be that the black hole just grew much faster than the galaxy surrounding it,
or maybe the galaxy's growth was stopped prematurely. Scientists aren't sure whether SAGE0536AGN is just a fluke
or whether they've found a new class of galaxies s

which fall into orbit about one another as a result of the merger between two galaxies. Like a pair of whirling skaters, the black-hole duo generates tremendous amounts of energy that makes the core of the host galaxy outshine the glow of its population of billions of stars
which scientists then identify as quasars. Scientists looked at Hubble archival observations of ultraviolet radiation emitted from the center of Markarian 231 (Mrk 231) to discover what they describe as xtreme and surprising properties.
such as those giant galaxies and clusters of galaxies, grows by merging smaller systems into larger ones,
and binary black holes are natural consequences of these mergers of galaxies, added co-investigator Xinyu Dai of the University of Oklahoma.
The lower-mass black hole is the remnant of a smaller galaxy that merged with Mrk 231.
Evidence of a recent merger comes from the host galaxy asymmetry and the long tidal tails of young blue stars.
The result of the merger has been to make Mrk 231 an energetic starburst galaxy with a star formation rate 100 times greater than that of our Milky way galaxy.
With this information the telescope is able to direct itself towards various objects in space including planets, galaxies, asteroids and stars automatically.

#Whopping Galaxy cluster Spotted with Help of NASA Telescopes Astronomers have discovered a giant gathering of galaxies in a very remote part of the universe, thanks to NASA Spitzer space telescope and Wide-field Infrared Survey Explorer (WISE.
Galaxy clusters are gravitationally bound groups of thousands of galaxies, which themselves each contain hundreds of billions of stars.
As light from remote galaxies makes its way to us, it becomes stretched to longer, infrared wavelengths by the expansion of space.
For infrared space telescopes, picking out distant galaxies is like plucking ripe cherries from a cherry tree.
these distant galaxies stand out as red dots, while closer galaxies look white. Astronomers first combed through the WISE catalog to find candidates for clusters of distant galaxies.
WISE catalogued hundreds of millions of objects in images taken over the entire sky from 2010 to 2011.
They then used Spitzer to narrow in on 200 of the most interesting objects, in a project named the assive and Distant Clusters of WISE Survey, or Madcows.

The galaxy is the most luminous found to date and belongs to a new class of mysterious objects known as'extremely luminous infrared galaxies',or Elrigs.
Named Wise J224607. 57-052635.0, scientists believe the galaxy may have a behemoth black hole at its heart
but how this black hole came to be so big remains a mystery.''We are looking at a very intense phase of galaxy evolution,
