The dark matter of the universe has a long lifetime
New research from the Niels Bohr Institute presents new information that adds another piece of knowledge to the jigsaw puzzle of the dark mystery of the universe - dark matter. The research has just been published in the scientific journal Physical Review Letters. view more (2007-10-02)
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)
Birth of a star predicted
The astrophysicist João Alves, director of the Calar Alto Observatory in Almeria, and his colleague Andreas Bürkert, from the German observatory in the University of Munich, believe that "the inevitable future of the starless cloud Barnard 68" is to collapse and give rise to a new star, according to an article which has been... view more...

APEX reveals glowing stellar nurseries
Illustrating the power of submillimetre-wavelength astronomy, an APEX image reveals how an expanding bubble of ionised gas about ten light-years across is causing the surrounding material to collapse into dense clumps that are the birthplaces of new stars. Submillimetre light is the key to revealing some of the coldest material in the Universe,... view more... (2008-11-12)
Climate gas could disrupt food chain
Levels of a climate cooling gas will change as carbon dioxide increases, affecting food webs along the way, said Dr Michael Steinke at a Science Media Centre press briefing today. view more (2007-12-11)
Interstellar searchlights catch star factories in their beams
Jets of particles from newly formed stars are acting like searchlights, piercing the gloom of dark interstellar clouds to pick out clumps of gas that may become future stars. Astronomers at University College London (UCL) and the University of Barcelona have discovered how these interstellar beams mark the clumps with a distinctive chemical... view more... (2002-04-04)
Cannibal stars like their food hot, XMM-Newton reveals
ESA's XMM-Newton has seen vast clouds of superheated gas, whirling around miniature stars and escaping from being devoured by the stars' enormous gravitational fields-giving a new insight into the eating habits of the galaxy's 'cannibal' stars. view more (2006-03-24)
Bringing space down to Earth to explain how stars form
In a laboratory in Nottingham, scientists are now creating the uniquely harsh conditions encountered in interstellar space. In an environment where the pressure is only one ten billion billionth (one part in 10 to the power 13) of atmospheric pressure, and the temperature a mere 10 degrees above absolute zero, Dr Martin McCoustra and his... view more...

Scientists solve cosmological puzzle
Researchers using supercomputer simulations have exposed a very violent and critical relationship between interstellar gas and dark matter when galaxies are born - one that has been largely ignored by the current model of how the universe evolved. view more (2007-11-30)
Magellanic gemstones in the southern sky
Hubble has captured the most detailed images to date of the open star clusters NGC 265 and NGC 290 in the Small Magellanic Cloud-two sparkling sets of gemstones in the southern sky. view more (2006-04-18)
NASA Scientists Detect Spectrum of Planets Orbiting Other Stars
For the first time, scientists at Goddard have obtained a spectrum, or molecular fingerprint, of a planet orbiting another star. Using spectroscopy, scientists were able to identify silicon dust in clouds on a gas-giant planet called HD 209458b. That planet is located 150 light years from Earth. view more (2007-02-23)

NASA's Swift satellite images a galaxy ablaze with starbirth
Combining 39 individual frames taken over 11 hours of exposure time, NASA astronomers have created this ultraviolet mosaic of the nearby "Triangulum Galaxy." view more (2008-02-26)
Scientists want to solve puzzle of excess water vapor near cirrus clouds
A number of researchers in recent years have reported perplexing findings of water vapor at concentrations as much as twice what they should be in and around cirrus clouds high in the atmosphere, a finding that could alter some conclusions about climate change. view more (2006-12-01)
Ice has a starring role - CMD19/CMMP with The Physics Congress 2002
When even moderately hot stars like our Sun have surface temperatures of around 6,000°C, it is hard to imagine that ice plays an important part in their formation. But that`s exactly what astrophysicists have recently discovered by turning to surface scientists for help. At the Condensed Matter conference on Monday 8 April, part of the... view more...

Ice clouds put Mars in the shade
Until now, Mars has generally been regarded as a desert world, where a visiting astronaut would be surprised to see clouds scudding across the orange sky. However, new results show that the arid planet possesses high-level clouds that are sufficiently dense to cast a shadow on the surface. view more (2008-01-17)
Scientists: Polar ice clouds may be climate change symptom
As the late summer sun sets in the Arctic, bands of wispy, luminescent clouds shine against the deep blue of the northern sky. view more (2007-08-21)
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)
Mapping the Milky Way
A new map of the centre of our own galaxy, The Milky Way, is the biggest, most detailed, and most sensitive yet made. The map shows giant streamers and huge clouds of interstellar gas where stars are being born 26,000 light years from Earth - shedding new light on the exotic structures in this unusual region of our own galaxy. An international... view more... (2000-12-19)
NASA'S Chandra finds black holes stirring up galaxies
