Latest Dark energy Stories
NASA's Hubble Space Telescope has looked deep into the distant universe and detected the feeble glow of a star that exploded more than 9 billion years ago.
With the last of the 2011 Nobel Laureates announced yesterday, it is noteworthy that five of these recipients have conducted research supported by the National Science Foundation (NSF)--Saul Perlmutter, Brian P. Schmidt and Adam G. Riess received the Nobel Prize in Physics; and Thomas J. Sargent and Christopher A. Sims received the Nobel Prize in Economics.
The largest survey to date of distant exploding stars is giving astronomers new clues to what’s behind the Type Ia supernovae they use to measure distances across the cosmos.
The powerful influence of the Sun and the nature of the mysterious 'dark energy' motivate ESA’s next two science missions.
Three scientists were awarded the Nobel Prize in physics on Tuesday for showing that the expansion of the universe is constantly accelerating.
'Bolshoi' supercomputer simulation provides new benchmark for cosmological studies.
Ohio State University researchers are leveraging powerful supercomputers to investigate one of the key observational probes of "dark energy," the mysterious energy form that is causing the expansion of the universe to accelerate over time.
"Zombie" stars that explode like bombs as they die, only to revive by sucking matter out of other stars.
NEW YORK, June 1, 2011 /PRNewswire/ -- Four astronomers who found a way to recreate the growth of the universe are the recipients of the 2011 Cosmology Prize of The Peter and Patricia Gruber Foundation.
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....
- A handkerchief.
- Specifically— The legendary sweat-cloth; the handkerchief of St. Veronica, according to tradition miraculously impressed with the mask of Christ; also, the napkin about Christ's head (Johu xx. 7).
- In general, any miraculous portrait of Christ.
