Latest Brown dwarfs Stories
Located about 440 light-years from Earth is a strange object that has properties of both a star and a planet.
Most brown dwarfs may contain storms as big as Jupiter’s “Great Red Spot,” according to findings presented at the American Astronomical Society in Washington.
Analysis of the two brown dwarfs located closest to the sun suggests that there could actually be a third, previously undetected planetary-mass object, according to research published as a letter to the editor in the journal Astronomy & Astrophysics.
While astronomers have previously calculated the threshold at which an object will become a star instead of a brown dwarf, observational evidence has been elusive.
A recently discovered exoplanet was found wandering the depths of space without the warming comfort of a nearby sun.
Two years ago NASA scientists revealed a new class of stars, dubbed ‘Y dwarfs’, thought to be about as warm as the human body. However, newly published research indicates that these cold stars are probably a bit warmer than the boiling point of water.
The W. M. Keck Observatory has successfully completed a $4 million campaign that will give astronomers the most detailed Adaptive Optics images of the cosmos ever created by mankind.
Astronomers have identified a body that is most likely a planet wandering throughout space without a parent star.
Penn State University astronomers have discovered record-breaking radio waves from an ultra-cool star that is not much warmer than the planet Jupiter.
A University of Toronto-led team of astronomers has discovered over two dozen new free-floating brown dwarfs, including a lightweight youngster only about six times heftier than Jupiter, that reside in two young star clusters.
Brown Dwarf -- Brown dwarfs are a special type of low-mass star (approximately 13-70 Jupiter masses) that do not have nuclear fusion occurring in their cores during their time on the main sequence. Early in their development most brown dwarf stars do have lithium fusion in their cores, and a lack of lithium is a test for low-mass objects that are suspected of being brown dwarfs. Many brown dwarfs continue to glow in the red and infrared after their lithium is exhausted. This glow is...
