Searching the heavens
A new space mission, due to launch this month, is going to shed light on some of the most extreme astrophysical processes in nature - including pulsars, remnants of supernovae, and supermassive black holes. view more (2008-05-01)
First Laboratory Experiment to Accurately Model Stellar Jets Explains Mysterious 'Knots'
Some of the most breathtaking objects in the cosmos are the jets of matter streaming out of stars, but astrophysicists have long been at a loss to explain how these jets achieve their varied shapes. Now, laboratory research detailed in the current issue of Astrophysical Review Letters shows how magnetic forces shape these stellar jets. view more (2009-02-10)
Exploring the digital Universe with Europe’s Astrophysical Virtual Observatory
A new European initiative called the Astrophysical Virtual Observatory (AVO) is being launched to provide astronomers with a breathtaking potential for new discoveries. It will enable them to seamlessly combine the data from both ground- and space-based telescopes which are making observations of the Universe across the whole range of wavelengths... view more...

Cluster makes a shocking discovery
ESA's Cluster was in the right place and time to make a shocking discovery. The four spacecraft encountered a shock wave that kept breaking and reforming - predicted only in theory. view more (2007-05-15)
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)
Turbulence May Promote the Birth of Massive Stars
On long, dark winter nights, the constellation of Orion the Hunter dominates the sky. Within the Hunter's sword, the Orion Nebula swaddles a cluster of newborn stars called the Trapezium. These stars are young but powerful, each one shining with the brilliance of 100,000 Suns. They are also massive, containing 15 to 30 times as much material as... view more... (2009-02-24)
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)
Creation of a magnetic field in a turbulent fluid
Understanding the origin and behavior of the magnetic fields of planets and stars is the goal of research being carried out by many teams from all over the world. view more (2007-03-12)
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)
Key mechanism for star formation found?
The team, led by Dan Clemens, from Boston University Institute for Astrophysical Research, examined a distant cloud of gas and dust called GF9, located about 1300 light years away. It shows a filamentary or wispy appearance, with dark "globules" distributed along its length. The new observation with ISO focused on two of these dark globules, one... view more... (1999-06-03)
NASA celebrates Chandra X-Ray Observatory's 10th anniversary
Ten years ago, on July 23, 1999, NASA's Chandra X-ray Observatory was launched aboard the space shuttle Columbia and deployed into orbit. view more (2009-07-24)
Worlds in collision
Two terrestrial planets orbiting a mature sun-like star some 300 light-years from Earth recently suffered a violent collision, astronomers at UCLA, Tennessee State University and the California Institute of Technology will report in a December issue of the Astrophysical Journal, the premier journal of astronomy and astrophysics. view more (2008-09-24)
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 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)
Magnetic Fields Play Larger Role in Star Formation than Previously Thought
he simple picture of star formation calls for giant clouds of gas and dust to collapse inward due to gravity, growing denser and hotter until igniting nuclear fusion. In reality, forces other than gravity also influence the birth of stars. New research shows that cosmic magnetic fields play a more important role in star formation than previously... view more...

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)
A new method to weigh giant black holes
How do you weigh the biggest black holes in the universe? One answer now comes from a new and independent technique that UC Irvine scientists and other astronomers have developed using data from NASA's Chandra X-ray Observatory. view more (2008-07-17)
Hotter than expected neutron star surfaces help explain superburst frequency
A new theoretical thermometer built from heavy-duty mathematics and computer code suggests that the surfaces of certain neutron stars run significantly hotter than previously expected. Hot enough, in fact, to at least partially answer an open question in astrophysics — how to explain the observed frequency of ultra-violent explosions known... view more... (2007-04-16)
Secrets from within planets pave way for cleaner energy
Research that has provided a deeper understanding into the centre of planets could also provide the way forward in the world's quest for cleaner energy. view more (2008-10-23)
