Elusive brown dwarfs

Post by brian livesey »

Astronomers believe that there could be at least 100 billion brown dwarfs hidden in our galaxy. The dwarfs, bigger than planets but smaller than stars and, therefore, incapable of nuclear fusion, are difficult to find. Those found so far are within 1,500 light years of Earth.
A study of near and far star clusters has revealed that the objects are likely to be common in our galaxy. Dr. Aleks Scholz at the University of St. Andrews said: "We've found a lot of brown dwarfs in these clusters, so our work suggests there are a huge number of brown dwarfs out there."
A special adaptive optics camera was used for the research, attached to the European Southern Observatory's Very Large Telescope in the Atacama Desert in Northern Chile.
