NASA’s James Webb Space Telescope has discovered a record-breaking small brown dwarf, only three to four times the mass of Jupiter. This finding challenges current…
This illustration depicts a brown dwarf – an object that is too heavy to be characterized as a planet, but not massive enough to power…
The Spanish-Mexican team has found that the boundary between those objects which destroy lithium and those which preserve it lies at 51.5 times the mass…
This artist’s illustration represents the five brown dwarfs discovered with the satellite TESS. These objects are all in close orbits of 5-27 days (at least…
Artist’s concept of 2MASS J22081363+2921215, a nearby brown dwarf. Though only roughly 115 light-years away, the brown dwarf is too distant for any atmospheric features…
Brown dwarfs are often called “failed stars.” They form like stars but are not massive enough to fuse hydrogen into helium as stars do. More…
Artist’s conception of a brown dwarf. Credits: NASA/ESA/JPL Planetary scientists wondered if bands of winds or swirling storms dominated the atmospheres of brown dwarfs. University…
Artist’s impression of the cold brown dwarf BDR J1750+3809. The blue loops depict the magnetic field lines. Charged particles moving along these lines emit radio…
Artist’s impression of one of this study’s superlative discoveries, the oldest known wide-separation white dwarf plus cold brown dwarf pair. The small white orb represents…
This artist’s concept shows a brown dwarf, a ball of gas not massive enough to power itself the way stars do. Despite their name, brown…
Artist’s conception of a brown dwarf and its magnetic field. The magnetic field, rooted deep in its interior, rotates at a different rate than the…
