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)
The Weirdest Type Ia Supernova Yet
A group of scientists affiliated with the SuperNova Legacy Survey (SNLS) have found startling evidence that there is more than one kind of Type Ia supernova, a class of exploding stars which until now has been regarded as essentially uniform in all important respects. view more (2006-09-21)
Missing planets attest to destructive power of stars' tides
During the last two decades, astronomers have found hundreds of planets orbiting stars outside our solar system. New research indicates they might have found even more except for one thing - some planets have fallen into their stars and simply no longer exist. view more (2009-04-28)
The Drifting Star
By studying in great detail the 'ringing' of a planet-harbouring star, a team of astronomers using ESO's 3.6-m telescope have shown that it must have drifted away from the metal-rich Hyades cluster. This discovery has implications for theories of star and planet formation, and for the dynamics of our Milky Way. view more (2008-04-16)
Supercomputer simulations shed light on cataclysmic variable flashes.
New supercomputer simulations may help explain periodic bursts of light emitted by compact binary star systems. view more (2005-03-31)
Hazy red sunset on extrasolar planet
A team of astronomers have used the NASA/ESA Hubble Space Telescope to detect, for the first time, strong evidence of hazes in the atmosphere of a planet orbiting a distant star. The discovery comes after extensive observations made recently with Hubble's Advanced Camera for Surveys (ACS). view more (2007-12-11)
European team finds smallest transiting extrasolar planet ever
The CoRoT satellite has discovered a planet only twice as large as the Earth orbiting a star slightly smaller than the Sun. It is the smallest extrasolar planet (planet outside our solar system) whose radius has ever been measured. view more (2009-02-03)
100th Extra-solar planet gives clues to origins of planets
British astronomers, together with Australian and American colleagues, have used the 3.9m Anglo-Australian Telescope [AAT] in New South Wales, Australia to discover a new planet outside our Solar System - the 100th to be detected. The discovery, which is part of a search for solar systems that resemble our own, will be announced today (Tuesday) at... view more... (2002-09-16)
Astonomers find tiny planet orbiting tiny star
An international team of astronomers led by David Bennett of the University of Notre Dame has discovered an extra-solar planet of about three Earth masses orbiting a star with a mass so low that its core may not be large enough to maintain nuclear reactions. The result was presented Monday (June 2) at the American Astronomical Society annual... view more... (2008-06-03)
The quiet explosion
A European-led team of astronomers are providing hints that a recent supernova may not be as normal as initially thought. Instead, the star that exploded is now understood to have collapsed into a black hole, producing a weak jet, typical of much more violent events, the so-called gamma-ray bursts. view more (2008-07-25)
Twin Star Explosions Fascinate Astronomers
Scientists using NASA's Swift satellite stumbled upon a rare sight, two supernovas side by side in one galaxy. view more (2006-11-21)
Astronomers find first ever gamma ray clock
Astronomers using the H.E.S.S. telescopes have discovered the first ever modulated signal from space in Very High Energy Gamma Rays - the most energetic such signal ever observed. view more (2006-11-28)
Scientists snap images of first brown dwarf in planetary system
Scientists using NASA's Spitzer Space Telescope have discovered and directly imaged a small brown dwarf star, 50 times the mass of Jupiter, orbiting with a planet around a Sun-like star. view more (2006-09-19)
The Glory of a Nearby Star
Optical Light from a Hot Stellar Corona Detected with the VLT The solar corona is a beautiful sight during total solar eclipses. It is the uppermost region of the extended solar atmosphere and consists of a very hot (over 1 million degrees), tenuous plasma of highly ionised elements that emit strong X-ray radiation. There is also a much weaker... view more... (2001-07-31)
Three satellites needed to bring out 'shy star'
An international team of scientists has uncovered a rare type of neutron star so elusive that it took three satellites to identify it view more (2005-07-14)
Largest collection of anomalous white dwarfs observed in new Hubble images
Twenty-four unusual stars, 18 of them newly discovered, have been observed in new Hubble telescope images. The stars are white dwarfs, a common type of dead star, but they are odd because they are made of helium rather than the usual carbon and oxygen. This is the first extensive sequence of helium-core white dwarfs to be observed in a globular... view more... (2009-04-23)
New insight in star formation
Early stages of star formation are now better understood, following an extensive millimeter-wave study of protostars, which are young stellar objects still deeply embedded in their parent molecular cloud. Thanks to their unprecedented high-resolution maps of the circumstellar environment of many young stellar objects, astronomers... view more... (2001-01-16)
Elevated Water Temperature and Acidity Boost Growth of Key Sea Star Species, UBC Researchers
New research by UBC zoologists indicates that elevated water temperatures and heightened concentrations of carbon dioxide can dramatically increase the growth rate of a keystone species of sea star. view more (2009-06-02)
ESA Director General Salutes China's First Human Space Flight
"Our warmest congratulations to the People's Republic of China on this outstanding achievement" said ESA Director General Jean-Jacques Dordain soon after the successful Shenzou launch. "China becomes the third country to send human beings into space, demonstrating the reliability of its aerospace technology. This mission could open up a new... view more... (2003-10-15)
Search for Sirius companions
Many direct or indirect observations have suggested the existence of a second companion (in addition of the white dwarf Sirius-B) around the brilliant star Sirius-A. The presence of a second faint star could in particular explain a change of color of Sirius, as suggested by historical texts. A team of astronomers of the CEA (Service of... view more...
