The Galactic clusters reveal distant Dwarf Galaxies

In the early ages our universe was dark and opaque, but a few million to billions of years after the big bang, over a bit lengthy Period of time mostly deemed as the “ionization period”, the neutral hydrogen was transformed into ionized plasma.

The researchers were gazing out the small part of the sky near the Orion, that is no more than a tiny little piece, 1/32 millionth part of the entire sky, through Hubble telescope, they found galaxies at a distance of 10 billion light-years, very similar to our own milky way galaxy. And there is a uniform entity of such galaxies nearby.

So the universe is uniform in overall, either we look in this direction or that, we would see gaze the same thing, astronomically this Model is regarded as “exploding egg model assigning us a special a place in entire universe and predicted the possibility of a large number of galaxies around us. But as we all quite aware of that fact that we are nowhere special but lies in a very ordinary part of the universe instead.

So the researcher's throwback to their most favorite genius guy, Albert Einstein’s, expanding space theory, there is more space welling up but it does not affect the thing bound together gravitationally or through some other sort of bonding forces. 
I.e. the Sun is not going away from the middle of Milky Way galaxy because it is gravitationally bound, concluded that the universe unbelievingly looks same, however, it is changing every time a bit faster rate. 

Another remarkable outcome of Einstein’s general theory of relativity that leads to the discovery of “gravitational lens”, the talk of the town today. Einstein came up the idea that highly massive objects in space could create a dent in space-time. If a gravitational lens falls in the direct line of sight of another object

Such as Dwarf galaxies, those are considered as the most abundantly found object in the universe, it can magnify light from the background. Since the galaxies are mostly found in the form of clusters, separated a sort of inland due to the continuous expansion of the universe, so there would have been the clumps of galaxies with the vast piece of empty spaces between them.

Recently, a team of researchers from California university, Riverside, consisting of Anahita Alavi and colleagues published their research paper in “ Astrophysics journal” , based on their groundbreaking efforts and research of a whole bunch of year, through Hubble telescope and with a wide field camera 3,and successfully took the deep images of three clusters of galaxies. This reach revealed the curtains over the early universe just after the big bang, when it was almost few billion years in age (four to six billions years approx.), this has expostulated as the most productive period in star formation. Since the Dwarf galaxies are the smallest and dimmest galaxies ever discovered, they are playing a vital role in assigning the “dark ages”, the past of the past of the universe.

After the careful observation of few of years, the team of California researchers reveals the clear infrared images of three clusters of galaxies they found, spotted by Hubble telescope. The light wrapped by these galactic clusters unearthed a large population of Dwarf galaxies, about 69 in number, those are 10 to 100 times fainter than the previously found galaxies, W.M Keck observatory confirmed that this discovery undoubtedly throwback the mankind into the ages when the universe was about two six billions years old.

The astrophysicists are sorting out the answer to most searched question of the day, the star formation and concluded that during this period of time , these dwarf galaxies housed the stars a bit faster rate than they do today and they are the real sources of ultraviolet radiations during that period.
