Diamonds from outer space — Geologists discover origin of Earth's mysterious black diamonds
If indeed "a diamond is forever," the most primitive origins of Earth's so-called black diamonds were in deep, universal time, geologists have discovered. Black diamonds came from none other than interstellar space. view more (2007-01-10)
Flies in a spider's web: Galaxy caught in the making
In nature spiders earn our respect by constructing fascinating, well-organised webs in all shapes and sizes. But the beauty masks a cruel, fatal trap. Analogously, the NASA/ESA Hubble Space Telescope has found a large galaxy 10.6 billion light-years away from Earth (at a redshift of 2.2) that is stuffing itself with smaller galaxies caught like... view more...

Milky Way's fastest pulsar is on its way out of the galaxy, astronomers find
The Milky Way's fastest observed pulsar is speeding out of the galaxy at more than 670 miles a second, propelled largely by a kick it received at its birth 2.5 million years ago. view more (2006-02-16)
Ultrafast star escapes black hole
Galactic nuclei are the cores of galaxies, groups of thousands to millions of stars that are held together by gravity. As stars in the nucleus are so close together, interactions readily occur. view more (2006-10-05)
Chandra discovers light echo from the Milky Way's Black Hole
Like cold case investigators, astronomers have used NASA's Chandra X-ray Observatory to uncover evidence of a powerful outburst from the giant black hole at the Milky Way's center. view more (2007-01-11)
Supernova radioisotopes show sun was born in star cluster, scientists say
The death of a massive nearby star billions of years ago offers evidence the sun was born in a star cluster, say astronomers at the University of Illinois at Urbana-Champaign. view more (2006-10-05)
NASA's Chandra Finds Evidence for Quasar Ignition
New data from NASA's Chandra X-ray Observatory may provide clues to how quasars "turn on." view more (2006-03-24)
New map of the Milky Way charts where stars are born
A team of astronomers from Boston University's Institute for Astrophysical Research has produced the clearest map to-date of the giant gas clouds in the Milky Way that serve as the birthplaces of stars. view more (2006-03-24)
Tycho's Remnant Provides Shocking Evidence for Cosmic Rays
Astronomers have found compelling evidence that a supernova shock wave has produced a large amount of cosmic rays, particles of mysterious origin that constantly bombard the Earth. view more (2005-09-23)
Two new dusty planetary disks may be astrophysical mirrors of our Kuiper Belt
A survey by NASA's Hubble Space Telescope of 22 nearby stars has turned up two with bright debris disks that appear to be the equivalent of our own solar system's Kuiper Belt, a ring of icy rocks outside the orbit of Neptune and the source of short-period comets. view more (2006-01-20)
New study questions dark matter in galaxies and clusters of galaxies
A new paper examines galaxy rotation curves without exotic dark matter and seeks to describe a modified Newtonian acceleration law derived from a relativistic modification of Einstein's gravitational theory. view more (2006-01-20)
Surprising telescope observations shake up galactic formation theories
A heavy form of hydrogen created just moments after the Big Bang has been found to exist in larger quantities than expected in the Milky Way, a finding that could radically alter theories about star and galaxy formation, says a new international study led by the University of Colorado at Boulder. view more (2006-08-15)
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)
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)
Evidence for ultra-energetic particles in jet from black hole
An international team of astronomers led by researchers at Yale has obtained key infrared observations that reveal the nature of quasar particle jets that originate just outside super-massive black holes at the center of galaxies and radiate across the spectrum from radio to X-ray wavelengths. view more (2006-06-21)

Galaxy evolution in cyber universe matches astronomical observations in fine detail
Scientists at the University of Chicago have bolstered the case for a popular scenario of the big bang theory that neatly explains the arrangement of galaxies throughout the universe. view more (2006-06-06)
Astrophysicists Listen to Loops Shivering on the Sun
You would imagine that a 500,000 kilometre long arch of super heated plasma releasing energy equal to the simultaneous explosion of 40 billion Hiroshima atomic bombs would be as easy to "hear" as it is to "see" - but it's not. Astrophysicists have long thought about using the acoustic waves in these flares to understand more... view more... (2004-02-17)
Galaxy Cluster Takes It to the Extreme
Evidence for an awesome upheaval in a massive galaxy cluster was discovered in an image made by NASA's Chandra X-ray Observatory. The origin of a bright arc of ferociously hot gas extending over two million light years requires one of the most energetic events ever detected. view more (2007-05-31)
Clash of clusters provides new dark matter clue
A powerful collision between galaxy clusters has been captured by the NASA/ESA Hubble Space Telescope and NASA's Chandra X-ray Observatory. This clash of clusters provides striking evidence for dark matter and insight into its properties. view more (2008-08-28)
