Scientists Make The Most Precise Measurment Of Early Universe Yet
2014-04-08 07:50:37

Lawrence LeBlond for redOrbit.com - Your Universe Online Two recent studies of the early Universe using the Baryon Oscillation Spectroscopic Survey (BOSS), a component of the third Sloan Digital Sky Survey (SDSS-III), have made the most accurate measurement of the rate of expansion in the early Universe to date. BOSS has pioneered the use of quasars to map density variations in intergalactic gas at high redshifts to trace the structure of the young Universe. BOSS helps scientists chart...

Massive Neutrinos Help Solve A Cosmological Conundrum
2014-02-10 09:36:04

University of Manchester Scientists have solved a major problem with the current standard model of cosmology identified by combining results from the Planck spacecraft and measurements of gravitational lensing in order to deduce the mass of ghostly sub-atomic particles called neutrinos. The team, from the universities of Manchester and Nottingham, used observations of the Big Bang and the curvature of space-time to accurately measure the mass of these elementary particles for the first...

Kinetic Sunyaev-Zel'dovich Effect Observed In Individual Object For The First Time
2014-01-17 11:14:32

redOrbit Staff & Wire Reports - Your Universe Online Scientists from the California Institute of Technology (Caltech) and NASA’s Jet Propulsion Laboratory (JPL) report in a recent study that they have observed a change in an individual object’s cosmic microwave background radiation resulting from its interaction with massive moving objects for the first time ever. According to the recently-published paper in The Astrophysical Journal, this phenomenon, which is known as the...

Brett Smith for redOrbit.com - Your Universe Online Based on observations from the South Pole Telescope, a team of international scientists has found subtle patterns in the cosmic microwave background called B-mode polarizations, according to a report in Physical Review Letters. “The detection of B-mode polarization by South Pole Telescope is a major milestone, a technical achievement that indicates exciting physics to come,” said study author John Carlstrom, a deputy director of...

Study Uses Big Bang Afterglow To Show Earth Has No Special Place In Expanding Universe
2013-11-07 07:53:48

Dartmouth College In a new study, Dartmouth researchers rule out a controversial theory that the accelerating expansion of the universe is an illusion. While the findings don't explain the cosmic speed-up, they eliminate one provocative possibility that our planet, solar system and galaxy are at the center of the universe and that there is no dark energy. The findings appear in the journal Physical Review D. The 2011 Nobel Prize was awarded for the discovery that the expansion of the...

Twisted Path Ancient Light Mapped

John P. Millis, PhD for redOrbit.com - Your Universe Online When astronomers peer into the deepest regions of the cosmos they are not seeing the Universe as it exists today, but rather how it looked billions of years ago. That's because light emitted by distant galaxies moves at a finite speed and therefore requires billions of years to reach Earth. Further complicating the matter is the fact that the light does not travel along a direct line of site to Earth. The photons are deflected...

ESA Shutting Down Planck Space Telescope
2013-10-18 16:29:49

Brett Smith for redOrbit.com – Your Universe Online After for four years surveying the Universe for the European Space Agency (ESA), the Planck space telescope’s Low Frequency Instrument will be turned off on Saturday, having completed its science operations on October 3. The telescope’s High Frequency Instrument ended operation in January 2012, after conducting five all-sky surveys. With some operational loose ends still to tie up, Planck will finally be switched off next week....

[ 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...

Yakov Borisovich Zel'dovich (March 8, 1914 "“ December 2, 1987) was a productive Soviet physicist. He was instrumental in the advancement of Soviet nuclear and thermonuclear weapons, and also was an invaluable assistance in the fields of adsorption and catalysis, shock waves, nuclear physics, particle physics, astrophysics, physical cosmology, and general relativity. In 1914, he was born into a Jewish family in Minsk, now called Belarus. Four months after his birth, he and his family...

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...

Cosmic Background Radiation -- The Big Bang theory predicts that the early universe was a very hot place and that as it expands, the gas within it cools. Thus the universe should be filled with radiation that is literally the remnant heat left over from the Big Bang, called the cosmic microwave background radiation, or CMB. When any patch of the sky is observed where no individual sources can be discerned, and the effects of the interplanetary dust, and interstellar matter are taken into...

Wilkinson Microwave Anisotropy Probe (WMAP) -- The Wilkinson Microwave Anisotropy Probe (WMAP) was launched on June 30, 2001 at 3:46 p.m. EDT at Cape Canaveral Air Force Station, Florida, USA. The goal of WMAP was to map out minute differences in the Cosmic Microwave Background (CMB) radiation which would help test theories of the nature of the universe. On February 11, 2003, the public relations group from NASA made a press release regarding the age and composition of the universe....
