Galaxies Far Far Away
by
Judith E Braffman-Miller
A vast multitude of incandescent stars emit their lovely glittering light within the more than 100 billion galaxies that float around in the observable Universe. In July 2012 astronomers reported the shocking discovery of a galaxy that should not be there--a fully-formed spiral galaxy dwelling in the very early Universe. The discovery presents an enticing mystery because this spiral galaxy already existed billions of years before most other spiral galaxies had the time to form.

Our Galaxy's Wicked Past
by
Judith E Braffman-Miller
The first galaxies were born very long ago, probably when the Universe was less than a billion years old. The favored theory of galaxy formation, the "bottom-up" theory, suggests that large galaxies, such as our own Milky Way, were rare in the early Universe, and that they eventually attained their enormous, mature sizes when they devoured smaller galactic snacks. In February 2013, astronomers using the venerable Hubble Space Telescope, announced that their observations of our Galaxy's outer limits revealed a shell of unfortunate stars--the sad left-overs of an ancient, wicked act of galactic cannibalism, by our own Milky Way, when it ruthlessly gobbled up smaller satellite galaxies.

Clusters Of Dazzling Galaxies
by
Judith E Braffman-Miller
Galaxy clusters are the largest gravitationally bound structures known to inhabit our Universe. These gigantic structures often contain thousands of incandescent galaxies, and two recent discoveries are some of the most dazzling yet.

Our Once And Future Galaxy
by
Judith E Braffman-Miller
The Andromeda galaxy is our Milky Way's nearest large galactic neighbor in Space. It is a spiral galaxy like our own, but it is a slightly larger spiral. Andromeda is about 2 million light-years away from us--at least, right now. Gravity is drawing Andromeda relentlessly toward our Milky Way at about 100 kilometers per second. In about 4 billion years our Galaxy will crash into and merge with Andromeda--creating the great ""Milkomeda" Galaxy!

Of Galaxies And Kings
by
Judith E Braffman-Miller
NGC 6872 is a breathtaking, star-bedecked, barred spiral galaxy, well-known for many years to be one of the biggest galaxies dancing around in the observable Universe. In January 2013, an international team of astronomers made the announcement that new observations have revealed that this enormous galaxy is the largest spiral observed so far in the Cosmos--and crowned it the King of Galaxies!

Young Galaxies Drink From Cosmic Spiral Straws
by
Judith E Braffman-Miller
Billions and billions of fiery stars send forth their brilliant, winking light within the more than 100 billion galaxies that dwell in the observable Universe. In May 2013, astronomers announced new computer simulations showing that young galaxies grow, over a span of billions of years, by sipping up their necessary nourishment of life-sustaining gas from a Cosmic version of spiral straws!

Mysterious Switched Off Galaxies
by
Judith E Braffman-Miller
More than 100 billion starlit galaxies dance around in our observable Universe. These lovely galaxies, flaming with the fires of billions and billions of stars, began to illuminate the primordial Universe less than a billion years after its inflationary Big Bang birth, almost 14 billion years ago. But some galaxies switch off and stop producing stars, and these so-called "quenched" galaxies have long been a mystery to astronomers-- this is because the "quenched" galaxies of the remote past appear to be considerably smaller than the "quenched" galaxies that dwell in our Universe today. In August 2013, Hubble COSMOS survey results were released suggesting there may be a surprisingly simple answer to this perplexing puzzle of cosmic proportions.

The Oldest Known Galaxy - So Far - Is Bursting With Stars
by
Judith E Braffman-Miller
In astronomy, there is an almost constant flow of announcements of the latest record-holder for the most distant and, therefore, oldest object yet discovered in the Cosmos--including galaxies, quasars, supernovae, and so on. In October, 2013 astronomers announced that they had caught a glimpse of the most distant, ancient galaxy seen--so far. However, this very old, very distant galaxy stood out in the crowd, because not only did it already exist when our almost 14 billion year old Universe was a mere toddler--it also showed the brilliant turbulence caused by frenetic star-birth. In fact, it had already experienced the fabulous birth and death of generations of stars by the time the Universe was a "mere" 700 million years of age!

Distant Galaxies In The Dark
by
Judith E Braffman-Miller
It is thought that small galactic embryos collided and merged together in the very early Universe to ultimately create the enormous and majestic galaxies that we observe today. In July 2012, astronomers announced the first observations of "dark galaxies". Dark galaxies are a predicted stage of ancient galactic formation, never before seen--until now.

A Massive Merger - Of Galaxies
by
Judith E Braffman-Miller
Billions and billions of stars blast the Cosmos with their beautiful, sparkling light as they do a joyful jitterbug within the more than 100 billion galaxies that haunt the observable Universe alone. The observable, or visible Universe, is that relatively small portion of the entire unimaginably enormous Cosmos that we are able to observe, both with our unaided eyes and with some very sophisticated telescopes. In May 2013, astronomers announced that they had observed a very rare and massive merger of two galaxies that occurred when the Universe was a mere child at "only" 3 to 4 billion years old. These new findings, made with the use of the European Space Agency's Herschel Space Observatory--with important NASA participation--help to explain the enticing mystery of how giant reddish elliptical-shaped galaxies were born in the early Universe.
