Faint ‘super-planet’ discovered by radio telescope for the 1st time | Space

Scientists have discovered a cold, faint “super-planet” that has remained elusive to traditional infrared survey methods. 

Observations from the Low-Frequency Array, or LOFAR radio telescope, revealed a brown dwarf, which researchers have designated BDR J1750+3809 and nicknamed Elegast. Brown dwarfs are sometimes referred to as failed stars or super-planets because they are too small to be considered stars, yet too big to be considered planets.
