A blue ring around the planet Uranus
The outermost ring of the planet Uranus turns out to have a bright blue color, according to a report in the April 7 issue of the journal Science. view more (2006-04-07)
Wobbly planets could reveal Earth-like moons
Moons outside our Solar System with the potential to support life have just become much easier to detect, thanks to research by an astronomer at University College London (UCL). view more (2008-12-12)
Massive star cluster found in Milky Way
A massive cluster of red supergiants-super-sized stars on the verge of exploding-was recently discovered in the Milky Way by a group of stronomers using infrared technology to penetrate the thick dust that cloaks much of the galaxy. view more (2006-01-10)
Astronomers discover missing link for origin of comets
An international team of scientists that includes University of British Columbia astronomer Brett Gladman has found an unusual object whose backward and tilted orbit around the Sun may clarify the origins of certain comets. view more (2008-09-05)
New stars from old gas surprise astronomers
Evidence of star birth within a cloud of primordial gas has given astronomers a glimpse of a previously unknown mode of galaxy formation. The cloud, known as the Leo Ring, appears to lack the dark matter and heavy elements normally found in galaxies today. view more (2009-02-19)
Multi-wavelength images help astronomers study star birth, death
In recent years, a number of ground-based optical and radio surveys of the Large and Small Magellanic Clouds - Earth's nearest neighboring galaxies - have become available. view more (2006-01-12)
Binary asteroid in Jupiter's orbit may be icy comets from solar system's infancy
Astronomers at the University of California, Berkeley, working with colleagues in France and at the Keck Telescope in Hawaii, have calculated the density of a known binary asteroid system that shares Jupiter's orbit, and concluded that Patroclus and its companion probably are composed mostly of water ice covered by a patina of dirt. view more (2006-02-02)
Mapping Orion's winds
For the past few months, Bob O'Dell has been mapping the winds blowing in the Orion Nebula, the closest stellar nursery similar to the one in which the sun was born. view more (2006-01-11)
Quasar light variability linked to black hole mass
Quasars are some of the most luminous and distant objects in the universe - and appear to have something in common with ordinary light bulbs. view more (2007-01-09)
First triple asteroid system found
One of the thousands of asteroids orbiting the sun has been found to have a mini planetary system of its own. view more (2005-08-11)
Superbubble of supernova remnants caught in act of forming
A superbubble in space, caught in the act of forming, can help scientists better understand the life and death of massive stars, say researchers at the University of Illinois at Urbana-Champaign. view more (2007-01-10)
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)
Record: fastest flashing star
Dutch researcher Steve van Straaten set a record during his doctoral research. The researcher registered the fastest ever change in the X-ray emission originating from a binary star. The record-breaking binary star consists of a neutron star and a lighter companion star. Astronomer Steve van Straaten studied the time variations in the X-ray... view more... (2004-05-07)
Astronomers detect echoes from ancient supernovae
A team of astronomers has found faint visible "echoes" of three ancient supernovae by detecting centuries-old light reflected by interstellar gas clouds hundreds of light-years removed from the original explosions. view more (2005-12-22)
UBC astronomers discover how white dwarf stars get their 'kicks'
University of British Columbia astronomer Harvey Richer and UBC graduate student Saul Davis have discovered that white dwarf stars are born with a natal kick, explaining why these smoldering embers of Sun-like stars are found on the edge rather than at the centre of globular star clusters. view more (2007-12-05)
XO-3b: Supersized planet or oasis in the 'brown dwarf desert'?
The latest find from an international planet-hunting team of amateur and professional astronomers is one of the oddest extrasolar planets ever cataloged -- a mammoth orb more than 13 times the mass of Jupiter that orbits its star in less than four days. view more (2007-05-31)
Astronomers find grains of sand around distant stars
In a find that sheds light on how Earth-like planets may form, astronomers this week reported finding the first evidence of small, sandy particles orbiting a newborn solar system at about the same distance as the Earth orbits the sun. The report will be published online this week by the journal Nature. view more (2008-03-13)
Hidden Planet Pushes Star's Ring a Billion Miles Off-Center
A young star's strange elliptical ring of dust likely heralds the presence of an undiscovered Neptune-sized planet, says a University of Rochester astronomer in the latest Monthly Notices of the Royal Astronomical Society. view more (2007-06-14)
First view of a newborn millisecond pulsar?
Combining Hubble Space Telescope images with radio observations has revealed a highly unusual system consisting of a fast spinning pulsar and a bloated red companion star. The existence of the system is something of a mystery - the best explanation so far is that we have our first view of a millisecond pulsar just after it has been `spun up` by... view more...

Dusty old star offers window to our future, astronomers report
Astronomers have glimpsed dusty debris around an essentially dead star where gravity and radiation should have long ago removed any sign of dust - a discovery that may provide insights into our own solar system's eventual demise several billion years from now. view more (2005-09-09)
