Light From Infant Universe

[ Watch the Video: Big Bang Signal Picked Up By Astronomers ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers report that they have detected a subtle signal from the Big Bang for the first time, giving a glimpse into the first moments of the Universe. The Cosmic Microwave Background (CMB) signal the astronomers detected was from when the universe was just 380,000 years old. The signal was found 13.8 billion years after bouncing around different areas of the Universe...

New Theory Explains Expansion Of Universe
2013-09-10 08:47:37

John P. Millis, PhD for redOrbit.com - Your Universe Online For the better part of a century the astronomical community has understood that the Universe is expanding, yet the exact nature of this expansion has been difficult to quantify. One extreme instance of this is the acceleration of galaxies receding from us billions of light-years away. But even looking closer to home, calculating the rate of expansion has proven difficult. Traditionally, scientists, measuring the recession...

Evolution Of Early Universe Successfully Simulated With Ultracold Big Bang Experiment
2013-08-29 10:22:39

University of Chicago Physicists have reproduced a pattern resembling the cosmic microwave background radiation in a laboratory simulation of the Big Bang, using ultracold cesium atoms in a vacuum chamber at the University of Chicago. “This is the first time an experiment like this has simulated the evolution of structure in the early universe,” said Cheng Chin, professor in physics. Chin and his associates reported their feat in the Aug. 1 edition of Science Express, and it will...

Cosmic Microwave Background Radiation Data Allows Furthest Look Back Through Time
2013-08-08 04:23:16

April Flowers for redOrbit.com - Your Universe Online The best way to solve a mystery, as any detective can tell you, is to revisit the scene where it began and look for clues. Scientists, searching for the mysteries of our universe, are trying to go back as far as they can to the Big Bang. Researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) conducted a new analysis of cosmic microwave background (CMB) radiation data to take the furthest look back yet. This look - 100...

Google Hangout: A New Baby Picture Of The Universe
2013-07-26 07:34:00

April Flowers for redOrbit.com - Your Universe Online This spring, scientists from the Max Planck Institute showed humanity the most detailed map ever created of the early universe. The map was generated from data gathered by the Planck spacecraft. It shows fluctuations in temperature in the relic radiation left over from the Big Bang - the moment when space and time came into existence nearly 14 billion years ago. This relic radiation is sort of like an afterglow of the Big Bang. It is...

“How to Understand the True Cosmos” aims to dispel misconceptions in astrophysics. Massachusetts (PRWEB) July 19, 2013 The rapid pace of scientific advancement in the field of astrophysics, and the new discoveries in the field and its sheer complexity has resulted in the obsolescence of many theories and models previously used to explain the nature of the universe and the celestial bodies within its expanse. With How to Understand the True Cosmos, Dr. Sol Aisenberg aims to improve the...

“Bright Hole Cosmos” was featured in the upcoming BookExpo America. Quebec (PRWEB) July 16, 2013 In 1929, Edwin Hubble discovered that the universe is in fact expanding at an enormous speed. This revolutionary discovery further supported the Big Bang theory which would, to this day, be the prevailing paradigm in cosmology. Author Andre Trepanier is not totally satisfied with this cosmological model and in his quest for answers, he discovered a defendable alternative theory: the...

The 2013 Gruber Cosmology Prize recognizes Viatcheslav Mukhanov and Alexei Starobinsky for their formative contributions to inflationary theory, an essential component for understanding the evolution and structure of the universe. According to the Prize citation, their theoretical work “changed our views on the origin of our universe and on the mechanism of its formation of structure.” Thanks to their contributions, scientists have provided a compelling...

Monstrous Stellar Collisions Not Expected To Occur Anytime Soon
2013-07-11 14:32:31

Lee Rannals for redOrbit.com - Your Universe Online Astrophysicists from the Astronomical Observatory of the Faculty of Physics at the University of Warsaw say the next collision of monstrous stars will not occur until billions of years from now. Three years ago, scientists discovered that the Magellanic Clouds host gigantic stars with between 200 and 300 times the solar mass  of our own Sun. Before then, astronomers believed that the biggest stars in the Universe did not...

Thales Alenia Space Leads Euclid Construction
2013-07-08 11:23:02

ESA The construction of ESA's Euclid space mission to explore the 'dark Universe' will be led by Italy's Thales Alenia Space as prime contractor, beginning the full industrial phase of the project. The announcement follows that of last month when Astrium Toulouse was confirmed to build the payload module - the telescope and optical bench carrying the science instruments. Euclid will be launched in 2020 to explore the roles played by dark energy and dark matter in the evolution of the...

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. Credit: NASA/Wikipedia What is Cosmology? I once commented to an acquaintance that I was fascinated by the field of Cosmology, and mused that if I had more time, I...

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...
