Astronomers have just found a cosmic cannonball.
led by Akanksha Khandelwal of the Physical Research Laboratory in India,"and a valuable addition to the population of less than five massive close-in giant planets in the high-mass planet and low-mass brown dwarf overlapping region that is further required for understanding the processes responsible for their formation."
Stars form from the top down, when a dense clump in a molecular cloud collapses under gravity to form a protostar. The star then grows by slurping up material from the cloud around it, which arranges into a disk. Brown dwarfs are thought to form like stars, from a clump of molecular cloud that collapses under gravity. They're usually found orbiting stars at quite a wide separation, at a minimum of a five astronomical units – that's five times the distance between Earth and the Sun.
