Lee Rannals for redOrbit.com — Your Universe Online Astronomers using the European Southern Observatory's (ESO) Very Large Telescope (VLT) have imaged possibly the faintest exoplanet so far. The team reported in Astrophysical Journal Letters that they imaged a faint object moving near a bright star. The exoplanet has an estimated mass of four to five times that of Jupiter, which could potentially make it the least massive planet to be directly observed outside the Solar System....

Astronomers may have found the first object clearing its path in the natal disc surrounding a young star Using ESO's Very Large Telescope an international team of astronomers has been able to study the short-lived disc of material around a young star that is in the early stages of making a planetary system. For the first time a smaller companion could be detected that may be the cause of the large gap found in the disc. Future observations will determine whether this companion is a planet or...

Astronomers have measured a superstorm for the first time in the atmosphere of an exoplanet, the well-studied "hot Jupiter" HD209458b. The very high-precision observations of carbon monoxide gas show that it is streaming at enormous speed from the extremely hot day side to the cooler night side of the planet. The observations also allow another exciting "first" "” measuring the orbital speed of the exoplanet itself, providing a direct determination of its mass. The results appear this...

As our telescopes grow more powerful, astronomers are uncovering objects that defy conventional wisdom. The latest example is the discovery of a planet-like object circling a brown dwarf. It's the right size for a planet, estimated to be 5-10 times the mass of Jupiter. But the object formed in less than 1 million years "” the approximate age of the brown dwarf "” and much faster than the predicted time it takes to build planets according to some theories. Kamen Todorov of Penn...

Brown dwarfs are the oddballs of the cosmos, more massive than planets but not heavy enough to generate the thermonuclear fusion that powers real stars. Now astronomers have found the coldest brown dwarf to date. The failed star might represent a new class of objects that are a missing link between planets and stars. The cold brown dwarf floats freely in space, not bound to a star. Its mass is somewhere between 15 and 30 times that of Jupiter. And it is about 660 degrees...

An international team led by French and Canadian astronomers has just discovered the coldest brown dwarf ever observed. Their results will soon be published in Astronomy & Astrophysics. This new finding was made possible by the performance of telescopes worldwide*: Canada France Hawaii Telescope (CFHT) and Gemini North Telescope, both located in Hawaii, and the ESO/NTT located in Chile.The brown dwarf is named CFBDS J005910.83-011401.3 (it will be called CFBDS0059 in the following). Its...

170 light-years away from earth exists a particularly puzzling orbiting object. This object, 2M1207B, seems to be physically impossible. Nothing about it matches any established astronomical theory. Eric Mamajek of the Harvard-Smithsonian Center for Astrophysics announced in a press conference, "This is a strange enough object that it needs a strange explanation." During this press conference, the 211th meeting of the American Astronomical Society, astronomers announced that 2M1207B might in...

First Directly Imaged Brown Dwarf Companion to an Exoplanet Host Star Astronomers have detected a new faint companion to the star HD 3651, already known to host a planet. This companion, a brown dwarf, is the faintest known companion of an exoplanet host star imaged directly and one of the faintest T dwarfs detected in the Solar neighbourhood so far. The detection yields important information on the conditions under which planets form. "Such a system is an interesting example that might...

Calgary, AB -- Earth's Moon was created by an early collision with another large planetary body. It was a "chip off the old block." Mars captured its asteroidal moons as they passed by. But Jupiter made its own moons out of dust and gas remaining from its formation. Now, observations by astronomer Subhanjoy Mohanty of the Harvard-Smithsonian Center for Astrophysics (CfA) and his colleagues provide the first direct evidence for a dusty disk around a distant planet that in mass would be...

Astronomers Confirm the First Image of a Planet Outside of Our Solar System ESO -- An international team of astronomers reports today confirmation of the discovery of a giant planet, approximately five times the mass of Jupiter, that is gravitationally bound to a young brown dwarf. This puts an end to a year long discussion on the nature of this object, which started with the detection of a red object close to the brown dwarf. In February and March of this year, the astronomers took new...

'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
