ESO eso1404: First Weather Map of Brown Dwarf- ESO's VLT charts surface of nearest brown dwarf.
This video shows the first ever map of the weather on the surface of the nearest brown dwarf to Earth.
The new images of the binary system are so accurate that they would have been able to reveal a brown dwarf 70 000 times fainter than the central star!
Up to now however, it has been impossible to actually image a faint brown dwarf so close to much brighter stars.
According to the brown dwarf interior models, typical conditions in the core for density,

object cannot be a normal star[5] but it could be either a brown dwarf[6] surrounded by dust
only 0.06 times that of the Sun, the brown dwarf has too little mass to ignite the thermonuclear reactions by which ordinary stars shine.
But the power of the newly installed SPHERE instrument on ESO's Very Large Telescope allowed the team to look for the first time exactly where the brown dwarf companion was expected to be.
Also, prevailing theories say that any grains that manage to form should move quickly towards the central brown dwarf, disappearing from the outer parts of the disc where they could be detected.
ALMA's increased resolution compared to previous telescopes also allowed the team to pinpoint carbon monoxide gas around the brown dwarf- the first time that cold molecular gas has been detected in such a disc.
