Latest Cosmic microwave background radiation Stories
In a new study, Dartmouth researchers rule out a controversial theory that the accelerating expansion of the universe is an illusion.
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.
After four years surveying the Universe for the European Space Agency, the Planck space telescope’s Low Frequency Instrument will be turned off on Saturday.
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.
Scientists have proposed a groundbreaking new theory to explain the discrepancies between different methods for measuring the expansion of the universe.
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.
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.
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.
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.
"If the Universe started with a bang, and no one was alive yet to observe it, would it still make a sound?" It sounds like the start of a really cliché joke, but the answer, surprisingly, is yes.
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....
