Why Are Milky Way-like Galaxies Are So Common In The Universe?
2014-09-17 03:11:17

ESO New observations explain why Milky Way-like galaxies are so common in the Universe An international research group led by Junko Ueda, a Japan Society for the Promotion of Science postdoctoral fellow, has made surprising observations that most galaxy collisions in the nearby Universe — within 40 million light-years from Earth — result in so-called disc galaxies. Disc galaxies — including spiral galaxies like the Milky Way and lenticular galaxies — are defined by...

Chuck Bednar for redOrbit.com - Your Universe Online Using a battery of observatories that included the Atacama Large Millimeter/submillimeter Array (ALMA) and the Hubble Space Telescope, an international team of astronomers has obtained the best view to date of a collision between two galaxies that took place when the universe was just a fraction of its current age. According to ESA, the team also utilized a gravitational lens to magnify galaxy HATLAS J142935.3-002836, revealing...

Droplets of star formation

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online As astronomers have sought to understand the formation and evolution of galaxies, a handful of simple truths have emerged. Despite many questions remaining, we know that galaxies form in clusters, and create interlinked chains and structures that create a spider web across the cosmos. [ Watch the Video: Hubblecast 76: Merging Galaxies And Droplets Of Starbirth ] Because they often move through the Universe in such close...

Clumpy Structure Makes Disk Galaxies Look Alike Over Time
2013-09-12 06:49:36

redOrbit Staff & Wire Reports - Your Universe Online Researchers at Iowa State University and IBM have identified why virtually all disk galaxies grow out of their irregular, clumped appearance, and why their older stars acquire the same smooth look as they fade from a bright center to a faint edge. The astronomers say that whether these young disk galaxies are big, small, isolated or crowded in a cluster, the reason they all eventually look alike is due to their clumpy structure,...

Astronomers Rethink Black Hole Growth Rate

Lee Rannals for redOrbit.com — Your Universe Online The rapidly expanding problem of obesity doesn't seem to just be limited to here on Earth, because new research published in the Astrophysical Journal suggests black holes are growing at larger rates than what had previously been thought possible Most galaxies have black holes at the center of them that can weigh anywhere from one million to one billion times as much as the Sun. The black hole found in the middle of our Milky...

Spiral Galaxy Is The Largest Ever Measured
2013-01-11 11:38:51

redOrbit Staff & Wire Reports - Your Universe Online While searching for data looking for star-forming regions around a galaxy located more than 200 million light years away, researchers have accidentally discovered that it is, in fact, the largest known spiral galaxy in the entire universe. As reported Friday by BBC News reporter Jason Palmer, a research assistant from NASA´s Goddard Space Flight Center and colleagues from the Catholic University of America (CUA), the...

Hubble Images Rare Spiral Galaxy With An Unusual Form
2012-12-06 09:19:14

[ Video 1 ] | [ Video 2 ] | [ Video 3 ] Lee Rannals for redOrbit.com - Your Universe Online A new Hubble Space Telescope image has been unveiled of NGC 922, revealing the cosmic structure to be an unusual spiral galaxy. The ring structure and distorted spiral shape of NGC 922 was imaged with NASA's Chandra X-ray Observatory to reveal even more chaos in the form of ultra luminous X-ray sources. The galaxy's unusual form is due to a cosmic bulls eye millions of years ago. A smaller...

Galactic Collisions Between Big Galaxies Form Even Bigger Galaxies

Brett Smith for redOrbit.com - Your Universe Online When massive galaxies belly-up to the interstellar buffet, their centers expand as they gobble up other galaxies that contain billions and billions of stars, according to a new report from University of Utah astronomers. "We found that during the last 6 billion years, the matter that makes up massive elliptical galaxies is getting more concentrated toward the centers of those galaxies. This is evidence that big galaxies are crashing...

Milky Way Destined For Head-On Collision
2012-06-05 03:18:55

[ Watch the Video ] NASA astronomers announced on May 31 that they can now predict with certainty the next major cosmic event to affect our galaxy, sun, and solar system: the titanic collision of our Milky Way galaxy with the neighboring Andromeda galaxy. The Milky Way is destined to get a major makeover during the encounter, which is predicted to happen four billion years from now. It is likely the sun will be flung into a new region of our galaxy, but our Earth and solar system are in...

Image 1 - GOODS-Herschel Reveals Gas Mass Role In Creating Fireworks Versus Beacons Of Star Formation
2012-03-27 09:24:29

A study of galaxies in the deepest far-infrared image of the sky, obtained by the Herschel Space Observatory, highlights the two contrasting ways that stars formed in galaxies up to 12 billion years ago. Dr Georgios Magdis will present the results at the National Astronomy Meeting in Manchester. Recent results from Herschel show that gas-rich galaxies in the early universe were able to create stars at an intense rate. In the nearby universe, we only see such high rates of star formation...

Seyfert's Sextet -- Seyfert's Sextet is a group of galaxies in which gravitational forces are exerted between its members. The galaxies are so tightly packed together that gravitational forces are beginning to rip stars from them and distort their shapes. Those same gravitational forces eventually could bring the galaxies together to form one large galaxy. The name of this grouping, Seyfert's Sextet, implies that six galaxies are participating in the action. But only four galaxies are...
