University of Hertfordshire expert David Pinfield led an international team of astronomers that was recently able to discover an ultra-cool, brown dwarf-class star. The object, located relatively nearby, may help astronomers make better distinctions between brown dwarfs and gas giant-class planets.
Pinfield says tha... |

An international collaboration of investigators says it has recently developed a new explanation for how stars known as brown dwarfs form. These objects sometimes blur the difference between very large gas giants and small stars, so explaining how they appear and why has been very difficult.
Astronomers have been tr... |

Astronomers believe they may have just imaged the first extrasolar planet featuring an Earth-like, temperate climate. Such conditions are a must for the development of life, in addition to the existence of liquid water and the presence of a magnetosphere. Over the past couple of years, the number of exoplanets that a... |

Astronomers operating the NASA Spitzer Space Telescope announce the discovery of the coldest known brown dwarf companion. The failed star can compare in temperature to other, similar cosmic bodies, which are floating freely through space, unbound to other objects.
Known as WD 0806-661, the new cosmic body is in fa... |

An international group of astronomers announces the discovery of the smallest known brown dwarf, a type of cosmic object that lies at the boundary between as star and a gas giant. These failed stars can dwarf Jupiter or Saturn, and now experts have discovered the smallest of them.
The discovery could have importan... |

Astronomers investigating data collected by an infrared telescope operated by NASA recently discovered the existence of the coolest class of stars in the Universe. These objects appear to have temperature levels comparable to those of the human body.Data to support this idea were collected by the NASA Wide-field Infr... |

Every galaxy may contain a very large number of extrasolar planets that is not bound to a parent star. These Jupiter-mass objects roam through the darkness of space without orbiting a star, or anything else for that matter. According to astronomers, this population is many times larger than originally estimated. In... |

Astronomers have recently discovered a small and weird population of stars in a cluster located some 20,000 light-years away from us. They say that these objects look very much like brown dwarfs, but add that something about them doesn't quite make sense. For instance, measurements of the objects conducted in in... |

A group of astronomers working in Chile believes it may have discovered the coolest brown dwarf star yet. Located in a a binary system, the star has a surface temperature of no more than100 degrees Celsius, which is the boiling point of water.While this may seem hot enough in human terms, it's nothing compared t... |

A group of astronomers was puzzled to discover a number of brown dwarfs while conducting a survey of a star cluster located relatively nearby in astronomical terms. The discovery is peculiar because we shouldn't theoretically be able to see objects such as these at such distances. The team's suspicions were... |

Scientists at the American space agency are thrilled to announce that one of their telescopes managed to discover signs of the existence of an ultra-cold star, called a brown dwarf. These objects cannot be readily classified as either stars or enormous gas giants. NASA used the Wide-field Infrared Survey Explorer (WI... |

A group of investigators recently announced the discovery of the coolest known group of brown dwarfs. This is a very special class of stellar objects, experts say, given that they are produced just like stars, but fail to ignite completely. For many years, the international astronomical community has been struggling ... |

Scientists in charge of managing the CoRoT (Convection, Rotation and Transits) space telescope announce the discovery of a set of six new exoplanets. The “selection” is very diverse, including bodies ranging from hot Jupiters to brown dwarfs, the peculiar objects which astronomers cannot really define pro... |

In a groundbreaking new investigation, a team of researchers discovered that the Universe can use the same mechanisms it employs in forming stars for producing large, planet-like objects. In a survey of 32 brown dwarfs, identified in he Taurus nebula of the Milky Way, astronomers found a weird object orbiting one of ... |

An international collaboration of astronomers has recently discovered the closest neighbor the Sun has, that it definitely outside of our solar system. The researchers say this is a Jupiter-sized object, most likely a very cool brown dwarf. It was found to be wandering around some 9 light-years away from the Sun, whi... |

Researchers at the University of Hertfordshire led an international team of astronomers in making one of the most peculiar discoveries in a long time. The group managed to identify a sub-stellar body technically known as a brown dwarf right in our neighborhood, inside the Local Fluff. The space object may very well b... |

Scientists from the Pennsylvania State University (Penn State) have recently discovered a new system of brown dwarfs orbiting a giant, dying star. Rather than clearing things up, the finding also served to deepen the mystery associated with brown dwarfs. It would appear that established astronomical knowledge is also... |

The international astronomical community is buzzing with excitement, following the announcement that the first observations of a planet-like object around its parent star have been made. The newly imaged bodies, which are known as GJ 758 B, and possibly GJ 758 C, orbit a Sun-like star located approximately 50 light-y... |

The Spitzer Space Telescope is one of the most renowned and important telescopes that the American space agency NASA currently has in orbit. Although the stage of its mission in which it observed the sky at super-low temperatures is over, it is still very capable of performing competitive science. This was again demo... |

Ultracold subdwarfs are a newly discovered class of stars that was found revolving around the Milky Way, in orbits that are so peculiar they make almost no sense. These peculiar, faint stars are not very bright, and they may even come from other galaxies, moving across the void that usually separates galactic formati... |
