Mapping the cosmic web of dark matter
What is Dark Matter and where is it found? These are two of the major mysteries in current studies of the Universe. Although the nature of this invisible material remains elusive, astronomers are beginning to produce detailed maps of the Cosmos, showing its location in relation to the ordinary matter that we can see in telescopes. One of the... view more... (2002-04-03)
Hubble finds large sample of very distant galaxies
New Hubble Space Telescope observations of six spectacular galaxy clusters acting as gravitational lenses have given significant insights into the early stages of the Universe. Scientists have found the largest sample of very distant galaxies seen to date: ten promising candidates thought to lie at a distance of 13 billion light-years (~redshift... view more... (2008-07-25)
Duke physicists see the cosmos in a coffee cup
A Duke University professor and his graduate student have discovered a universal principle that unites the curious interplay of light and shadow on the surface of your morning coffee with the way gravity magnifies and distorts light from distant galaxies. view more (2009-04-15)
'Cosmic telescopes' may have found infant galaxies
Using massive clusters of galaxies as "cosmic telescopes," a research team led by a Johns Hopkins University astronomer has found what may be infant galaxies born in the first billion years after the beginning of the universe. view more (2006-06-06)
Collaboration shines possible light on objects 'weirder than black holes'
Researchers from Duke University and the University of Cambridge think there is a way to determine whether some black holes are not actually black. view more (2007-09-25)
Cosmic Lens Reveals Distant Galactic Violence
By cleverly unraveling the workings of a natural cosmic lens, astronomers have gained a rare glimpse of the violent assembly of a young galaxy in the early Universe. Their new picture suggests that the galaxy has collided with another, feeding a supermassive black hole and triggering a tremendous burst of star formation. view more (2008-10-21)
'Listen, two black holes are clashing!'
MiniGRAIL: first spherical gravitational wave antenna in the world view more (2004-11-26)
FSU physicist shining a light on mysterious 'dark matter'
We've all been taught that our bodies, the Earth, and in fact all matter in the universe is composed of tiny building blocks called atoms. Now imagine if this weren't the case. view more (2007-10-03)
A Hungry Quasar Caught in the Act
The VLT Secures Spectacular Image of Distant Gravitational Interaction A new image of a distant quasar (the luminous core of an "active" galaxy) shows that it is engaged in a gravitational battle with its neighbouring galaxies. It also provides information on how supermassive black holes present in the center of quasars are fed. Using the FORS2... view more... (2001-05-31)
Scientists predict how to detect a fourth dimension of space
Scientists at Duke and Rutgers universities have developed a mathematical framework they say will enable astronomers to test a new five-dimensional theory of gravity that competes with Einstein's General Theory of Relativity. view more (2006-05-26)
GEO600 starts continuous search for Gravitational Waves
The joint German-British Gravitational Wave Detector GEO600 has now entered an 18-month run of continuous measurement. view more (2006-06-27)
A simple survey yields a cosmic conundrum
A survey of galaxies observed along the sightlines to quasars and gamma-ray bursts-both extremely luminous, distant objects-has revealed a puzzling inconsistency. Galaxies appear to be four times more common in the direction of gamma-ray bursts than in the direction of quasars. view more (2006-08-01)
First Image and Spectrum of a Dark Matter Object
Astronomers have observed a Dark Matter object directly for the first time. Images and spectra of a MACHO microlens - a nearby dwarf star that gravitationally focuses light from a star in another galaxy - were taken by the NASA/ESA Hubble Space Telescope and the European Southern Observatory's Very Large Telescope. The Riddle of Dark Matter The... view more... (2001-12-05)
Hubble finds double Einstein ring
The NASA/ESA Hubble Space Telescope has revealed a never-before-seen optical alignment in space: a pair of glowing rings, one nestled inside the other like a bull's-eye pattern. The double-ring pattern is caused by the complex bending of light from two distant galaxies strung directly behind a foreground massive galaxy, like three beads on a... view more... (2008-01-11)
Astronomers discover largest-ever dark matter structures spanning 270M light-years
A University of British Columbia astronomer with an international team has discovered the largest structures of dark matter ever seen. Measuring 270 million light-years across, these dark matter structures criss-cross the night sky, each spanning an area that is eight times larger than the full moon. view more (2008-02-22)
JHU-STScI team maps dark matter in startling detail
Clues revealed by the recently sharpened view of the Hubble Space Telescope have allowed astronomers to map the location of invisible "dark matter" in unprecedented detail in two very young galaxy clusters. view more (2005-12-12)
Scientists 'Weigh' Tiny Galaxy Halfway Across Universe
A tiny galaxy, nearly halfway across the universe, the smallest in size and mass known to exist at that distance, has been identified by an international team of scientists led by two from the University of California, Santa Barbara. view more (2007-10-04)
GAMMA RAYS AND DARK MATTER
For a long time it has been known that the Milky Way is surrounded by a (nearly spherical) halo of invisible matter, which contributes at least 90% of the whole galactic mass. Yet, almost nothing is known about the nature of such a dark halo. view more (1999-02-26)
Old idea spawns new way to study dark matter
An international team of astronomers led by Ohio State University has examined dark matter in the outer reaches of our galaxy in a new way. For the first time, they were able to employ triangulation -- a method rooted in ancient Greek geometry -- to estimate the location of dark matter and calculate its mass. view more (2007-05-31)
Cosmic dance helps galaxies lose weight
A study published this week in the journal Nature offers an explanation for the origin of dwarf spheroidal galaxies. The research may settle an outstanding puzzle in understanding galaxy formation. view more (2009-07-30)
