Latest Dark energy Stories
In 2011, the Nobel Prize for Physics was awarded to a trio of researchers. Adam Riess, Saul Perlmutter and Brian Schmidt were able to determine that the speed and scope of the expansion of the universe is not so uniform as once believed.
The NASA/ESA Hubble Space Telescope has broken the record in the quest to find the furthest supernova of the type used to measure cosmic distances.
Cosmologists using data from ESA's Planck satellite have compiled the first all-sky image of the distribution of dark matter across the entire history of the Universe as seen projected on the sky.
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.
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.
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.
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....
