The object is one of nine new brown dwarfs confirmed by the James Webb Space Telescope in a deeper survey of IC 348, a star-forming region about 1,000 light-years away in Perseus. The Astrophysical Journal Letters study extends the population of spectroscopically classified brown dwarfs down to an estimated two Jupiter masses.
