ESA's Planck Space Mission Creates Highly-Detailed Map Of The Universe
2013-03-21 12:44:54

Lee Rannals for redOrbit.com — Your Universe Online Using technologies contributed by NASA, the European Space Agency's (ESA) Planck space mission has provided the most accurate and detailed map made of the oldest light in the Universe. Results from Planck are giving a more detailed look into our Universe's history than ever before. The map suggests that the Universe is expanding more slowly and is 100 million years older than scientists previously thought. The data also shows...

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online In order to illuminate the darkness we turn to the light. Whether the sun, a lamp, or a candle, we rely on electromagnetic radiation to reveal the world, and indeed the Universe, around us. Everything that we see - every tree, every planet, and every star - we see because it emits, reflects, bends and focuses light to our eyes. Without the interaction of matter with light, we are blind. But what about matter that...

NASA Joins ESA In Euclid Mission
2013-01-24 12:37:25

Lee Rannals for redOrbit.com - Your Universe Online NASA and the European Space Agency (ESA) are partnering up on the Euclid mission to investigate dark matter and dark energy together. The Euclid space telescope will launch in 2020 with about a 4-feet-diameter telescope and two scientific instruments that will map the shape, brightness and 3D distribution of two billion galaxies. With the mission, "scientists hope to solve key problems in our understanding of the evolution and fate...

WASHINGTON, Jan. 24, 2013 /PRNewswire-USNewswire/ -- NASA has joined the European Space Agency's (ESA's) Euclid mission, a space telescope designed to investigate the cosmological mysteries of dark matter and dark energy. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Euclid will launch in 2020 and spend six years mapping the locations and measuring the shapes of as many as 2 billion galaxies spread over more than one-third of the sky. It will study the evolution of our...

Dark Energy Theory Challenged
2013-01-10 09:15:38

[ Listen to the Podcast “The Search For Dark Energy” ] redOrbit Staff & Wire Reports - Your Universe Online A popular theory that relies on dark energy, thought to be the main contributor to the accelerating expansion of the Universe does not fit newly obtained data with regards to one fundamental constant — the proton to electron mass ratio. Rodger Thompson, a University of Arizona astronomy professor, disclosed his findings Wednesday at the American...

WMAP Final Results Released
2012-12-22 05:47:09

redOrbit Staff & Wire Reports - Your Universe Online The researchers in charge of an award-winning space mission that set out to collect fundamental measurements of the universe have announced they will be releasing their final results after nearly a decade of work. The Wilkinson Microwave Anisotropy Probe (WMAP), which was launched in June 2001, has collected data that has "revolutionized our view of the universe, establishing a cosmological model that explains a widely diverse...

Lawrence Berkeley National Laboratory $2.1 Million Grant to Berkeley Center for Cosmological Physics advances dark energy research at UC Berkeley and Berkeley Lab A $2.1 million grant from the Gordon and Betty Moore Foundation to the University of California at Berkeley, through the Berkeley Center for Cosmological Physics (BCCP), will fund the development of revolutionary technologies for BigBOSS, a project now in the proposal stage designed to study dark energy with unprecedented...

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...

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...

Quintessence (Dark Energy) -- Quintessence or dark energy is a hypothetical form of energy postulated to exist in order to explain observations of an accelerating universe. This energy would act like a vacuum pressure, pushing things apart. Other attempts to explain these recent observations involve a non-zero cosmological constant, which has the same effect. Indeed, sometimes quintessence is said to result in a non-zero cosmological constant, and conversely a non-zero cosmological...

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....
