Possible cosmic defect may be a window into the early universe
An unusual cold spot in the oldest radiation in the universe, the cosmic microwave background, may be caused by a cosmic defect created just after the Big Bang, a Spanish and U.K. research team has found. view more (2007-10-26)
Yale Astronomer Discovers Upper Mass Limit for Black Holes
here appears to be an upper limit to how big the universe's most massive black holes can get, according to new research led by a Yale University astrophysicist. view more (2008-09-12)
Scientists Detect Cosmic 'Dark Flow' Across Billions of Light Years
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. view more (2008-09-24)
Physicists create a 'perfect' way to study the Big Bang
Physicists have created the state of matter thought to have filled the Universe just a few microseconds after the big bang and found it to be different from what they were expecting. Instead of a gas, it is more like a liquid. Understanding why it is a liquid should take physicists a step closer to explaining the earliest moments of our Universe. view more (2005-07-21)
Astronomers detect stellar ashes at dawn of time
Using a powerful instrument on a telescope in Hawaii, UK astronomers have found ashes from a generation of stars that died over 10 billion years ago. This is the first time that the tell-tale cosmic dust has been detected at such an early stage in the evolution of the universe. view more (2002-04-10)
Shedding light on the cosmic skeleton
"Matter is not distributed uniformly in the Universe," says Masayuki Tanaka from ESO, who led the new study. "In our cosmic vicinity, stars form in galaxies and galaxies usually form groups and clusters of galaxies. The most widely accepted cosmological theories predict that matter also clumps on a larger scale in the so-called... view more... (2009-11-03)
Where are the supermassive black holes hiding?
European and American scientists, on a quest to find super-massive black holes hiding in nearby galaxies, have found surprisingly few. Either the black holes are better hidden than scientists realised or they are lurking only in the more distant universe. view more (2006-07-27)
First detection of magnetic field in distant galaxy produces a surprise
Using a powerful radio telescope to peer into the early universe, a team of California astronomers has obtained the first direct measurement of a nascent galaxy's magnetic field as it appeared 6.5 billion years ago. view more (2008-10-02)
Vanderbilt astronomers participate in new search for dark energy
The most ambitious attempt yet to trace the history of the universe has seen "first light." The Baryon Oscillation Spectroscopic Survey (BOSS), part of the Sloan Digital Sky Survey III (SDSS-III), took its first astronomical data on the night of Sept. 14-15 at the Sloan Foundation telescope in New Mexico. view more (2009-10-02)
Astronomers Expect To Be "Dazled" By Views Of Ancient Universe
ROYAL ASTRONOMICAL SOCIETY PRESS NOTICE: ASTRONOMERS EXPECT TO BE "DAZLED" BY VIEWS OF ANCIENT UNIVERSE view more (2005-04-05)
NASA Balloon Mission Tunes in to a Cosmic Radio Mystery
Listening to the early universe just got harder. A team led by Alan Kogut of NASA's Goddard Space Flight Center in Greenbelt, Md., today announced the discovery of cosmic radio noise that booms six times louder than expected. view more (2009-01-08)
Science with Integral -- 5 years on
With eyes that peer into the most energetic phenomena in the universe, ESA's Integral has been setting records, discovering the unexpected and helping understanding the unknown over its first five years. view more (2007-10-18)
What is time?
The concept of time is self-evident. An hour consists of a certain number of minutes, a day of hours and a year of days. But we rarely think about the fundamental nature of time. view more (2005-04-13)
Dark energy existed in infant universe
Using NASA's Hubble Space Telescope, researchers have discovered that dark energy, a mysterious repulsive force that makes the universe expand at an ever-faster rate, is not new but rather has been present in the universe for most of its 13-billion-year history. view more (2006-11-17)
Scientists discover possible cosmic defect, remnant from Big Bang
Scientists from the Institute of Physics of Cantabria (IFCA) and the University of Cambridge may have discovered an example of a cosmic defect, a remnant from the Big Bang called a texture. view more (2007-10-26)
The first 3-D map of the universe
By analyzing the COSMOS field, the largest field of galaxies ever observed with the Hubble space telescope, an international team of scientists led by researchers from the California Institute of Technology (United States) and researchers from the associated laboratories of the CNRS and the CEA , made the first three-dimensional map of dark matter... view more...

Hubble`s Advanced Camera unveils a panoramic new view of the Universe
Jubilant astronomers today unveiled humankind`s most spectacular views of the Universe as captured by the NASA/ESA Hubble Space Telescope`s new Advanced Camera for Surveys (ACS). They also reported that Hubble is operating superbly since the March servicing mission and are looking forward to more pictures from the newly revived NICMOS camera.... view more... (2002-04-30)
Discovery confirms explosive prediction made by astrophysicists in 1999
NASA's Swift satellite and ground-based telescopes have discovered the most distant exploding star on record, confirming a 1999 prediction made by University of Chicago astrophysicist Don Lamb and Daniel Reichart, who was then a graduate student at Chicago. view more (2005-09-13)
Swift Satellite records early phase of gamma ray burst
UK astronomers, using a telescope aboard the NASA Swift Satellite, have captured information from the early stages of a gamma ray burst - the most violent and luminous explosions occurring in the Universe since the Big Bang. view more (2009-03-03)
VIMOS - a Cosmology Machine for the VLT
Successful Test Observations With Powerful New Instrument at Paranal One of the most fundamental tasks of modern astrophysics is the study of the evolution of the Universe. This is a daunting undertaking that requires extensive observations of large samples of objects in order to produce reasonably detailed maps of the distribution of galaxies in... view more...
