Brown dwarfs reveal exoplanets' secrets

Brown dwarfs are smaller than stars, but more massive than giant planets. As such, they provide a natural link between astronomy and planetary science. However, they also show incredible variation when it comes to size, temperature, chemistry, and more, which makes them difficult to understand, too. New work surveyed various properties of 152 suspected young brown dwarfs in order to categorize their diversity and found that atmospheric properties may be behind much of their differences. Ref.

Surprise! When a brown dwarf is actually a planetary mass object

Sometimes a brown dwarf is actually a planet -- or planet-like anyway. A team discovered that what astronomers had previously thought was one of the closest brown dwarfs to our own Sun is in fact a planetary mass object. Ref. Source 2q.

I think as we get more and more into studying the universe we will learn a lot more and maybe learn a way to develop a star drive that will bring the stars much closer to us in the way of interstellar travel. To think that these brown dwarf stars may be cooling and shrinking enough to be planet like instead of star like is pretty interesting stuff.
