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)

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)

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)

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)

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)

Unveiling the Secret of a Virgo Dwarf Galaxy
Dwarf galaxies may not be as impressive in appearance as their larger brethren, but they are at least as interestingfrom a scientific point of view. And sometimes they may have hidden properties that will only be found by means of careful observations, probing the signals of their stars at the... view more (2000-05-03)

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)

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)

Shrinking giants, exploding dwarves
When white dwarf stars explode, they leave behind a rapidly expanding cloud of 'stardust' known as a Type Ia supernova. These exploding events, which shine billions of times brighter than our sun, are all presumed to be extremely similar, and thus have been used extensively as cosmological... view more (2007-08-28)

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)

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)

A Vanishing Star Revisited
Reinhold H'¤fner of the Munich University Observatory (Germany) is a happy astronomer.   view more (1999-07-20)

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... view more (2000-11-24)

Plutoid chosen as name for Solar System objects like Pluto
Almost two years after the International Astronomical Union (IAU) General Assembly introduced the category of dwarf planets, the IAU, as promised, has decided on a name for transneptunian dwarf planets similar to Pluto.   view more (2008-06-12)

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... view more (2002-02-13)

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)... view more (2008-06-03)

A link between antidepressants and type 2 diabetes
While analyzing data from Saskatchewan health databases, Lauren Brown, researcher with the U of A's School of Public Health, found people with a history of depression had a 30 per cent increased risk of type 2 Diabetes.   view more (2008-03-26)

Medical College researchers find dinosaur clues in fat
A team of researchers at New York Medical College has discovered why birds, unlike mammals, lack a tissue that is specialized to generate heat.   view more (2008-04-24)

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,... view more (2002-08-01)

University research shows that Tony Blair is benefiting from the presence of Gordon Brown
A survey conducted at the Centre for the Study of Group Processes, University of Kent, has thrown up some interesting results in the final run-up to the general election.   view more (2005-05-03)

Researcher turns brown algae phylogeny upside down
According to fellow phycologists, algae expert Stefan Draisma from the Leiden University has turned brown algae phylogeny completely upside down. His research shows that few of the currently assumed relationships between the orders are correct. Furthermore, it transpires that some simple species... view more (2002-06-24)

The missing link in the evolution of magnetic cataclysmic stars?
An international team of astronomers might have discovered the missing link in the evolution of the so-called magnetic cataclysmic variable stars. They determined the spin and orbital periods of the binary star Paloma.   view more (2007-09-17)

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)

Why are there so many more species of insects? Because insects have been here longer
J. B. S. Haldane once famously quipped that "God is inordinately fond of beetles." Results of a study by Mark A. McPeek of Dartmouth College and Jonathan M. Brown of Grinnell College suggest that this fondness was expressed not by making so many, but rather by allowing them to persist for... view more (2007-04-04)

Double-star systems cycle between big and small blasts
Certain double, or binary, star systems erupt in full-blown explosions and then flare up with smaller bursts, according to new information gathered by NASA's Galaxy Evolution Explorer (GALEX) and analyzed by a team of astronomers, including postdoctoral researcher Mark Seibert of the Carnegie... view more (2007-03-08)
