A cerebral volume that basically presents the analyses of the human scientific knowledge and its significance and contribution to a better understanding of the creation of the universe and life on earth Brazil (PRWEB) January 12, 2013 The universe and life on earth are like a labyrinth that needed to be solved. They pose many questions that relentlessly seeking for answers. How the universe was created? How will it end? Did God made it? What is the truth about extra-terrestrial life,...

Magnetic Fields Created Before Stars In The Early Universe

Lee Rannals for redOrbit.com — Your Universe Online An astronomer wrote in the journal Physical Review Letters about a new mechanism for the magnetization of the early universe. Before stars formed, luminous matter consisted only of fully ionized gas of protons, electrons, helium nuclei and lithium nuclei which were produced during the Big Bang. “All higher metals, for example, magnetic iron could, according to today´s conception, only be formed in the inside of...

Astronomers Discover 7 Primitive Galaxies
2012-12-13 08:30:25

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have discovered seven primitive galaxies that formed more than 13 billion years ago, during the Universe's infancy. The find includes a candidate galaxy that could hold the record for the most distant galaxy ever found. Scientists made the new discoveries using the Hubble Space Telescope's Hubble Ultra Deep Field project, which aims to improve our understanding of the early Universe. Astronomers are looking back at...

Spotting Distant Galaxy Clusters With WISE

April Flowers for redOrbit.com - Your Universe Online As grand and colorful as it is, our solar system is a fleck in the grander cosmos. Our Milky Way galaxy has hundreds of billions of solar systems, yet it is only just a drop in the sea of galaxies. Galaxy clusters, the rarest and largest of galaxy groupings, can be the hardest to find, which is where NASA's Wide-field Infrared Survey Explorer (WISE) becomes helpful. So far, the mission's all-sky infrared maps have revealed one...

April Flowers for redOrbit.com - Your Universe Online The universe has had traces of heavy elements such as carbon and oxygen as far back in time as astronomers have been able to see. Elements such as these were originally churned from the explosion of massive stars. They formed the building blocks for planetary bodies, and eventually for life on Earth. Peering back far in time, a research team from MIT, Caltech, and the University of California at San Diego (UCSD) found matter...

Scientists Offer New Insights Into Early Universe

Lee Rannals for redOrbit.com — Your Universe Online Penn State University scientists using techniques from modern physics have developed a new understanding of the earliest eras in the history of the universe. The scientists now have an extended analyses that include quantum physics farther back in time than ever before, heading back to the very beginning. The new paradigm of loop quantum origins show that the large-scale structures we see in the universe evolved from...

Galaxy Clusters Offer Insight On Dark Matter
2012-11-21 09:56:07

April Flowers for redOrbit.com - Your Universe Online Dark Energy is one of the major puzzles of modern astronomy, and one tool that astronomers use to understand this force is encoded in the distribution of clusters of galaxies. A new study by a team of astronomers, led by Dr. Jeeseon Song at the University of Michigan, has yielded exquisitely precise distances of a large sample of clusters. These precise distances may lead to breakthroughs in understanding the expansion history of our...

Near Infrared Technology Lets Astronomers Study Numerous Galaxies At The Same Time

April Flowers for redOrbit.com - Your Universe Online Some 24 robotic arms attached to a new high tech instrument have been transported from Edinburgh, Scotland to a Chilean mountaintop in the hope that some of the key questions surrounding the beginnings of the Universe will be answered in greater detail than ever before. The European Southern Observatory (ESO) has provisionally accepted KMOS after testing was completed at the UK Astronomy Technology Centre (UK ATC) in Edinburgh....

The winners of a contest that encourages scientists and students across the globe to explore fundamental, big questions in astronomy and cosmology will present their proposals and essays in a joint conference Oct. 12-13 at the Franklin Institute in Philadelphia. The New Frontiers in Astronomy & Cosmology International Grant and Essay Competition, led by Donald G. York, the Horace B. Horton Professor in Astronomy & Astrophysics at the University of Chicago, will award more than $4...

Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

Large-Scale Structure of the Cosmos -- Stars are organised into galaxies which in turn appear to form clusters and superclusters, separated by voids. Prior to 1989 it was commonly assumed that the superclusters were the largest structures in existence, and that they were distributed more-or-less uniformly throughout the universe in every direction. However, in 1989, Margaret Geller and John Huchra discovered the "Great Wall", a sheet of galaxies more than 500 million light years long...

Cosmology -- area of science that aims at a comprehensive theory of the structure and evolution of the entire physical universe. Modern Cosmological Theories Present models of the universe hold two fundamental premises: the cosmological principle and the dominant role of gravitation. Derived by Hubble, the cosmological principle holds that if a large enough sample of galaxies is considered, the universe looks the same from all positions and in all directions in space. The second point...

Redshift -- Redshift is the phenomenon that the frequency of light when observed, under certain circumstances, can be lower than the frequency of light when it was emitted at the source. This usually occurs when the source moves away from the observer, as in the Doppler effect. More specifically, the term redshift is used for the observation that the spectrum of light emitted by distant galaxies is shifted to lower frequencies (towards the red end of the spectrum, hence the name) when...

Quasar -- A quasar (from quasi-stellar radio source) is an astronomical object that looks like a star in optical telescopes (i.e. it is a point source), but has a very high redshift. The general consensus is that this high redshift is cosmological, the result of Hubble's law and that their redshift indicates that they are typically very distant from Earth; we observe them as they were several billions of years ago. Since we can see them despite their distance, they must emit more...
