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)

It may not be long before we see other worlds
WE MAY actually see a planet around a nearby star within the next six months. A team of British astronomers hope to achieve this feat by focusing their search on white dwarfs-dimly glowing stars at the end of their lives.         Although more than 80... view more (2002-03-06)

NASA sees orbiting stars flooding space with gravitational waves
A scientist using NASA's Chandra X-ray Observatory has found evidence that two white dwarf stars are orbiting each other in a death grip, destined to merge.   view more (2005-05-30)

Mystery of R Coronae Borealis and other helium stars solved
Astronomers Dr Simon Jeffery of the Armagh Observatory and Dr Hideyuki Saio of Tohoku University, Japan, have finally solved a long-standing mystery concerning the creation of two particular kinds of rare stars. They have found that a class of variable stars named after their prototype R Coronae... view more (2002-03-25)

White Dwarf Pulses Like a Pulsar
New observations from Suzaku, a joint Japanese Aerospace Exploration Agency (JAXA) and NASA X-ray observatory, have challenged scientists' conventional understanding of white dwarfs. Observers had believed white dwarfs were inert stellar corpses that slowly cool and fade away, but the new data tell... view more (2008-01-03)

Hubble sees faintest stars in a globular cluster
The NASA/ESA Hubble Space Telescope has uncovered what astronomers are reporting as the dimmest stars ever seen in any globular star cluster.   view more (2006-08-21)

Astronomers see faintest stars in a globular cluster
Astronomers report in the Aug. 18 issue of the journal Science seeing the faintest stars ever seen in any globular star cluster. The light from these dim stars is only as bright as the light produced by a birthday candle on the moon, as seen from Earth. The astronomers used NASA's Hubble Space... view more (2006-08-21)

Astronomers use Hubble to 'weigh' Dog Star's companion
For astronomers, it's always been a source of frustration that the nearest white-dwarf star is buried in the glow of the brightest star in the nighttime sky. This burned-out stellar remnant is a faint companion of the brilliant blue-white Dog Star, Sirius, located in the winter constellation Canis... view more (2005-12-13)

NTT Observations Indicate that Brown Dwarfs Form Like Stars
Dusty Disks Detected around Very Young Substellar Objects in the Orion Nebula An international team of astronomers is announcing today the discovery of dusty disks surrounding numerous very faint objects that are believed to be recently formed Brown Dwarfs in the Orion Nebula. This finding is based... view more (2001-06-07)

100 Photographs in the Blink of an Eye
Scientists from the Universities of Sheffield and Southampton in collaboration with the UK Astronomy Technology Centre at the Royal Observatory, Edinburgh have just opened a new window on the Universe by commissioning ULTRACAM - an ultra-fast camera which can take up to 1000 pictures a second in... view more (2002-07-24)

Stellar still births
The systematics of celestial bodies apparently needs to be revised. Researchers at the Argelander Institute of Astronomy of the University of Bonn have discovered that brown dwarfs need to be treated as a separate class in addition to stars and planets.   view more (2008-08-25)

X-rays provide a new way to investigate exploding stars
ESA's X-ray observatory XMM-Newton has revealed a new class of exploding stars - where the X-ray emission 'lives fast and dies young'.   view more (2007-05-10)

Hubble images some of galaxy's dimmest stars
Using the Hubble Space Telescope, astronomers have imaged some of the galaxy's oldest and dimmest stars, offering a rare experimental glimpse of two mysterious star types - tiny, slow burners less than one-tenth the size of our sun and once giant stars that still glow more than 10 billion years... view more (2006-08-21)

Young stars in chaos
It is not only teenagers who like to congregate in intimate groups and disturb their neighbours and surroundings. As Matthew Bate (University of Exeter), will be explaining to the UK National Astronomy Meeting in Bristol on Friday 12 April, young stars also like to hang around in crowds and... view more (2002-04-04)

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)

Planet or failed star? One of smallest stellar companions seen by Hubble
Astronomers using the NASA/ESA Hubble Space Telescope have photographed one of the smallest objects ever seen around a normal star beyond our Sun. Weighing in at 12 times the mass of Jupiter, the object is small enough to be a planet.   view more (2006-09-11)

Eclipsing brown dwarfs provide new key to the star formation process
Pity the brown dwarf. It's too large to be a planet, but too small to be a star.   view more (2006-03-16)

Hubble panoramic view of Orion Nebula reveals thousands of stars
In one of the most detailed astronomical images ever produced, the NASA/ESA Hubble Space Telescope is offering an unprecedented look at the Orion Nebula.   view more (2006-01-12)

Planets like earth may have formed around other stars, UCLA astronomers report
The chemical fingerprint of a burned-out star indicates that Earth-like planets may not be rare in the universe and could give clues to what our solar system will look like when our sun dies and becomes a white dwarf star some five billion years from now.   view more (2007-08-20)

Faintest Methane Brown Dwarf Discovered with the NTT and VLT
Brown Dwarfs are star-like objects which are heavier than planets but not massive enough to trigger the nuclear burning of hydrogen and other elements which powers normal stars. They are, nevertheless, heated during their formation by gravitational contraction but then continuously cool as this... view more (1999-08-18)

Even 'failed stars' form planets
An international team of astronomers shows that even brown dwarfs start to form planets.   view more (2005-10-26)

Delay in spotting TB is more common in white people and women
Delays in diagnosing tuberculosis are more common in white people and women, finds a study in this week’s BMJ.   view more (2003-04-23)

Study reveals ethnic differences in treatment for heart disease
South Asian patients are less likely to receive treatment for coronary artery disease than white patients, finds a study in this week's BMJ.   view more (2002-02-27)

Astronomers Weigh the Coldest Brown Dwarfs with Astronomy's Sharpest Eyes
Astronomers have used ultrasharp images obtained with the Keck Telescope and Hubble Space Telescope to determine for the first time the masses of the coldest class of "failed stars," a.k.a. brown dwarfs.   view more (2008-06-03)

A Brown Dwarf Joins the Jet-Set
Jets of matter have been discovered around a very low mass 'failed star', mimicking a process seen in young stars. This suggests that these 'brown dwarfs' form in a similar manner to normal stars but also that outflows are driven out by objects as massive as hundreds of millions of solar masses... view more (2007-05-24)
