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 on detailed observations with SOFI, a specialised... view more... (2001-06-07)
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)
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 undergo chaotic close encounters with each other during... view more...

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)
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)
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)
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 down to Jupiter-sized objects. view more (2007-05-24)
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 energy is radiated away. The so-called Methane Brown... 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)
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)
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)
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)
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)
Dark and distant heavenly bodies revealing the secrets of star and galaxy formation
British astronomers are releasing the first data from the largest and most sensitive survey of the heavens in infrared light to scientists across Europe. view more (2006-07-24)
A Planet in Progress?
Scientists are one step closer to understanding how new planets form, thanks to research funded by the National Science Foundation (NSF) and carried out by a team of astrophysicists at the American Museum of Natural History. view more (2008-03-27)
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 planets outside our Solar System have been discovered,... view more... (2002-03-06)
Disks around Failed Stars - a Question of Age
First Ground-Based Mid-Infrared Observations of Brown Dwarfs [1] A team of European astronomers [2] have observed eight Brown Dwarfs, i.e., small and faint objects also known as "failed stars", with the TIMMI2 infrared sensitive instrument at the ESO 3.6-m telescope on La Silla. From two of these, mid-infrared radiation is detected - for the first... view more... (2002-08-01)
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 Telescope. view more (2006-08-21)
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)
