The Oldest Galaxy to Be Found, Yet!

Reading about the discoveries and the work of astronomers continues to be fascinating!  A recent posting has given information about the discovery of a spiral galaxy which is supposed to be the oldest spiral galaxy that has been discovered, thus far!  Telescopic views and studies have identified this particular galaxy as being around 10.7 billion years old!

The universe itself is estimated to be 13.7 billion years old, give or take a couple of billion.  Scientists have reached this conclusion through studies of images captured by telescopic viewings, especially through the use of The Hubble Space Telescope.  The Hubble constant is used also, where researchers factor in things like the recognized amounts of matter and dark energy, and the levels of density with these items of the universe.

The galaxy has been labeled as BX442.  The discovery of this ancient galaxy puts a drastic level of pressure to the currently recognized ideas about how the age of the universe.  It’s presence as a completely in-tact structure, having a full spiral shape that can be easily identified, indicates that more time must have been available for this galaxy to reach a stable form.  Astonomers did not believe that galaxies were fully-shaped and indentifiable at such an ancient point of time.

I had read somewhere that our Milky Way is supposed to be a middle-aged galaxy.  Yet, with the current estimates of it being around 13.6 billion years old, that would make our home galaxy pretty ancient!  It would have to have begun forming shortly after The Big Bang.  I will need to review more details, to work out the facts about ages of the universe, and of our galaxy.

The observations and recordings of beryllium that are used to estimate the age of the universe.  This element is found within the oldest stars of the galaxy.  It was formed as cosmic rays within the young universe interacted with, collided with heavier elements that were present.  The isotope Beryllium-9, in particular, was formed through this method, and this element is being identified in studies of older stars that can provide information about the age of the universe.

It is all pretty interesting!  As an actual lamen, in regard to how all of this astronomy stuff works, I was looking at some of the recent online postings, while trying to make sense of it all.  I will likely proceed to read other related sites that give information about the age of the universe, and how things like stars first began to take shape.  It is fascinating to recognize how long that all of what is known is supposed to have existed!

Aside:  I got caught up, listening to the television behind me, and hearing the latest levels of stupidity flying out of Rush Limbaugh‘s mouth!  He is claiming that Bane, the character from the Batman series, and featured in this latest movie release, is a planned slam at Mitt Romney!  Limbaugh has said that Bane (spelled B-A-N-E) is a slam at a business venture that Romney has worked with, called Bain (B-A-I-N).  Nevermind that this D.C. Comics character first appeared in Batman stories around 1993; not new at all!
