Earliest galaxies detected: NASA

1 comments

US space agency NASA has said that,” Thirteen billion years old ultra-blue galaxies, which were formed around 700 million years after the Big Bang, have been discovered by astronomers.”

Using NASA's Hubble Space Telescope, astronomers from University of California have broken the distance limit for galaxies by uncovering the primordial population of compact and ultra-blue galaxies that were not seen before.

These newly-found galaxies are crucial to recognize the link between the birth of the first stars, the formation of the first galaxies and the sequence of evolutionary events that resulted in the assembly of Milky Way and other "mature" elliptical and majestic spiral galaxies in today's universe.

The Hubble Ultra Deep Field 2009 (HUDF09) team combined the new Hubble data with observations from NASA's Spitzer Space Telescope to judge the ages and masses of these primordial Galaxies.

"The masses are just one per cent of those of the Milky Way," clarified team member Ivo Labbe of the Carnegie Observatories.

He further noted that "to our surprise, the consequences show that these galaxies existed at 700 million years after the Big Bang and must have started forming stars hundreds of millions of years earlier, pushing back the time of the earliest star formation in the universe."

    ...inter-universe travel constant acceleration (parallel universes)... Big-Bang!!...whether separation among galaxies, where all stay in the expansive surface of sphere, goes accelerating by the supposed antigravity of the supposed dark energy (perhaps accelerating because they attract with the galaxies from the Neighbor Universe)...perhaps expand until it collide with another shock wave from another Big-Bang of multi-Universe...(why was there clustering all the Universe´s ENERGY in 1 only sphere?, does not only there is 1 star...multiple spheres of energy here and there...each sphere a Local Universe with its Big-Bang...so, the UNIVERSE would be like a galaxy with its stars, each "star" a Local Universe)...which divided up the same Infinite EMPTY SPACE (such as a group of balloons, each one separated from each other, to be swelling...the space inside and out, the Infinite Empty Space...and each balloon an independent Local Universe)... And if Gravitation shall get to stop the expansion, it´s evident that the fragments approximation (galaxies in apocalyptic collisions) would start among them with those nearest over the sphere´s surface, forming hyper-massive "clumps" of Matter ever increasing until the start of major gravitational attraction with other "clumps" from the opposite end of sphere´s diameter already implosive...starting implosion in terminal phase of our and then uninhabitable Local Universe (maybe by then would have completed the inter-Universe exodus and there would be no one in this)... Exit to direction at 180º from center increasing our radius, distance from the center where there was the Big-Bang, to the opposite direction going towards the center of sphere would get more "inside" of our own Universe instead of going out. Maybe "nearer" the next Universe going to the same direction of expansion, that going at counter-expansion to "antipodes" (Galaxy Abell 1835...13200 million light years... to 1 Million G, 9800 kms/sec²...at halfway maximum hyperluminal-speed = 3.7 light-years/second...total travel time = 226 years) of our... The Travel of all travels... Ship "Exodus-1"...heading 180º from center towards the Infinite...constant acceleration until to detect at front galaxies with strong differential deflection, discounting our own hyperluminal-speed, toward the Violet...the shock wave from our New Universe come to greet us...(and, no sooner said than done, launched themselves towards the gloomy darkness of Infinite)... Parallel Universes, we only carry the truth.. Here we go...goooooo!►...
