Latest Dark energy Stories
NASA and the European Space Agency are partnering up on the Euclid mission to investigate dark matter and dark energy together.
A popular theory that emphasizes dark energy as a contributor to the acceleration of the universe’s expansion does not fit newly obtained data with regards to one fundamental constant – the proton to electron mass ration – claims a University of Arizona astronomy professor.
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.
In 1998 scientists measuring the expansion of the Universe made a startling discovery: the Universe is accelerating. Previously, researchers believed that the expansion of the Universe would eventually slow under the influence of gravity.
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 precision.
Astronomers use the distribution of clusters of galaxies to understand dark matter, and a research team has just used this tool to help understand the expansion history of our universe.
The American Institute of Physics (AIP) has selected author Richard Panek as winner of this year’s AIP Science Communication Award in the Science Writing category for his book The 4% Universe: Dark Matter, Dark Energy, and the Race to Discover the Rest of Reality.
Astronomers have developed an algorithm that is able to chart and explain accurately the structure and dynamics of the universe.
Since the 1990's, dark energy has been the most accepted hypothesis to explain the expansion rate of the Universe. A hypothetical form of energy, dark energy is thought to permeate all of space and accounts for about 73% of the total mass-energy of the universe.
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.

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....
