Latest Observable universe Stories
WASHINGTON, Jan. 26, 2011 /PRNewswire-USNewswire/ -- Astronomers have pushed NASA's Hubble Space Telescope to its limits by finding what is likely to be the most distant object ever seen in the universe.
Seven years ago Northwestern University physicist Adilson E Motter conjectured that the expansion of the universe at the time of the big bang was highly chaotic.
ESAâ€™s Planck mission has delivered its first all-sky image that not only provides new insight into the way stars and galaxies form but also tells us how the Universe itself came to life after the Big Bang.
Distant galaxy clusters mysteriously stream at a million miles per hour along a path roughly centered on the southern constellations Centaurus and Hydra.
GREENBELT, Md., March 10 /PRNewswire-USNewswire/ -- Distant galaxy clusters mysteriously stream at a million miles per hour along a path roughly centered on the southern constellations Centaurus and Hydra.
Scientists using data from the U.S. space agency's Wilkinson Microwave Anisotropy Probe have identified an unexpected motion in distant galaxy clusters.
As if the mysteries of dark matter and dark energy weren't vexing enough, another baffling cosmic puzzle has been discovered. Patches of matter in the universe seem to be moving at very high speeds and in a uniform direction that can't be explained by any of the known gravitational forces in the observable universe.
Using data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP), scientists have identified an unexpected motion in distant galaxy clusters. The cause, they suggest, is the gravitational attraction of matter that lies beyond the observable universe.
Cosmologists are always complaining about their inability to find the dark matter in the universe, invisible stuff that's supposedly more prevalent than regular matter.
A critically important number that specifies the expansion rate of the Universe, the so-called Hubble constant, has been independently determined using NASA's Chandra X-ray Observatory.
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.
