NASA Scientists Stumble Upon a Very Special Cosmic Event

NASA Scientists Stumble Upon a Very Special Cosmic Event

By Ron G Anselm

Galaxies in space are so vast that the night sky is as ever-flowing as a waterfall with no bottom. These huge entities are mostly taken for granted when someone gets the chance to look at them from the lens of any telescope or observatory. We all know about the Milky Way galaxy that makes me think about candy bars and the Milk Man delivering the morning bottles of cereal busters and how this huge entity has given scientist more excitement to look at than a teenage girl shopping for her first Prom Dress. 

The world of galaxies has also extended to the ranks of professional sports where the big guns of baseball have launched balls that seemed like they were heading for the closest galaxy only to make its way to the upper deck of any baseball stadium. Back when the Age of the Power Hitters in baseball put fear in most pitchers I used to love to watch a rookie pitcher on the mound try to throw an 75 mile per hour hanging curve ball to hitters like Mark McGwire and Sammy Sosa and from the best era of baseball in my opinion back in the 1970s Dave Kingman and home run kings like these guys only to watch the look of Whoops! 

On the pitchers face as he released the ball knowing he had less sideways spin on it than needed for a good curve ball that has lots of movement on it and to see one of these guys standing at the plate trying to have patience waiting on the ball to make it to the plate and then watch their eyes open as wide as a fat man`s gut as they take that monster cut at the ball, connect and watch the ball launch like a 155MM shell out of a howitzer towards space. Or, field goal kickers in the NFL like the sure footed Sebastian Janikowski from my Oakland Raiders who used to be a soccer player turned professional field goal kicker; kick field goals from unheard of distances as the ball just keeps climbing as he connects. It`s like watching the Space Shuttle take off headed for the next neighboring galaxy.  

So, have you ever wondered how galaxies were actually formed? Now NASA`s Herschel Space Observatory as spotted the massive and rare merging of two galaxies come together like two drunk couples on a date in the back seat of their 1950 Chevy Convertible Coup. 

These two galaxies according to NASA`s Hubble Space telescope and Spitzer Space telescope were intertwined and furiously making stars. Sounds almost like the two intertwined galaxies were the two drunk couples in the back seat of their Chevy doing the nasty but the two drunk couples wouldn`t be making stars they would be making something else if one of them didn`t wrap that little rascal. Now back to Science and your mind out of the gutter.... (Couldn`t resist that one) 

A great piece of information this new discovery by NASA has given scientists is to the age of question, back when our universe was three to four billion years old and was populated with large and reddish, elliptical-shaped galaxies which were made-up of mostly old stars; did those galaxies build-up slowly over time through the acquisitions of smaller galaxies? Or, were those same galaxies formed by rapidly powerful collisions between two large galaxies? 

The new information is leaning more to the hypotheses that massive mergers are responsible for these wondrous and giant, elliptical galaxies. Hai Fu of the University of California at Irvine, who is lead author of a new study describing the results. The study is published in the May 22 online issue of Nature, added his two cents on this by saying, "We`re looking at a younger phase in the life of these galaxies " an adolescent burst of activity that won`t last very long. " (Fu, H.) 

Asantha Cooray who is one of Hai Fu`s co-workers also from the University of California also commented on this, "These merging galaxies are bursting with new stars and completely hidden by dust. Without Herschel`s far-infrared detectors, we wouldn`t have been able to see through the dust to the action taking place behind."(Cooray, A.) 

During this study, the scientist conducting it at first glance through the special lens of the Hubble and Spitzer telescopes thought they were just looking at a warped view of the two galaxies which is common in astronomy when the gravity rom a foreground galaxy bends the light from a more distance object but as the referees in the NFL say after a review of a protested call by one or the other opposing teams and it goes to the booth for review, After further review...in this case NASA said After further review, we are not looking at a warped view of two galaxies but are looking at a massive galaxy merger." 

NASA also found out that these two massive galaxies are making and spewing out about two-thousand stars a year. You say, Two-thousand stars a year? So, since I am not a scientist or an astronomer, is that a lot of stars in science terms? To compare if this is a lot of stars being put out by a galaxy you have to make a mental graph chart in your head. Here are the data points, our Milky Way galaxy puts out roughly two to three stars a year and these two active galaxies are putting out two-thousand stars a year? Yes, I would say in science terms that is a lot of stars. The night sky will be as bright as a second grader with a 170 IQ with all these newly born stars plotting our universe.

Most astronomers say that it is common to see mergers happen in our universe but what makes this event special is the amount of gas and star formation taking place in it. So, this event is now a mark in the world of science and will continue to be a record in the Guinness Book of Science (if there is really one) until the next mark in the topic of merging galaxies tops this current one.

In the world of astronomy and science the merging of galaxies is an event that is so special the comprehension of this blows the mind. In sports, the game of baseball is so special that kids suddenly become big league players overnight, or at least in their dreams they do. My next book titled, Our Grand Ol` National Past Time "A Brief History of Major League Baseball" is unique in the world of literature because it separates itself from other books on baseball and defies any competition.
