Recent astronomical observations found a cosmic phenomenon that shatters previous records for the lowest stellar temperature at which radio waves can be produced. Researchers were able to find flaring radio emissions coming from an ultra-cool, brown dwarf-class star.

A team of astronomers studying a brown dwarf star relatively far away from Earth announced at a conference yesterday that the object is most likely being shaken up by tremendous storms on its surface. The new study reveals more data on the elusive nature of such objects.
Brown dwarfs cannot be analyzed in great de... |

A recent discovery brightens astronomers' day as they spotted a brown dwarf tightly orbiting a young sun-like star. This discovery was made possible by the Near-Infrared Coronagraphic Imager, or NICI, on the international 8-meter Gemini-South Telescope in Chile and the lucky finders are part of a team led by Uni... |

The Two Micron All Sky Survey (2MASS) initiative performed by NASA's Infrared Processing and Analysis Center found what was thought to be a single, common brown dwarf planet, which was called 2M 0939, short for 2MASS J09393548-2448279. There was nothing special about it and not much attention was paid to it &nda... |

The concept of brown dwarfs is somewhat cloudy to astronomers, and it describes a planet not large enough to be a star, although it shares some characteristics, it seems. Scientists from the Harvard-Smithsonian Center for Astrophysics (CfA) located in Cambridge, Massachusetts, have managed to accomplish a task they t... |

Brown dwarf stars are the coldest class of failed stars in the universe, some of which weighing as little as 3 percent of the mass of the Sun, insufficient to start nuclear fusion reactions in their core, thus being unable to generate their own internal energy. Just like with gas giants, observations regarding the ma... |

The newly discovered object, dubbed MOA-2007-BLG-192Lb, is a terrestrial planet roughly three times as heavy as Earth orbiting a star called MOA-2007-BLG-192L located about 3,000 light years away from us. The finding also marks the discovery of the smallest star to have a planet orbiting around it, since it only weig... |

Brown dwarfs, or failed stars, are stellar bodies with masses 10 to 70 times higher than Jupiter's. Although, like all stars, they have the capability of initiating thermonuclear fusion reactions in their cores, their masses do not permit them to sustain these reactions for a very long time, unlike typical stars... |

The star system we talk about is located around a well-studied star known as AB Aurigae. The star is relatively young and surrounded by a disk of material created from a gas and dust cloud that seems to be forming some kind of object inside it, like the gas giant of a brown dwarf star. Co-author of the study, Ben R. ... |

The universe originated in a Big Bang event more than 13 billion years ago, no doubt about that. However, much of its previous history and complexity misses key elements, which are necessary in order to create an accurate theory of the universe's evolution. As space telescopes get better, they enable us to view ... |
