ScienceWebb reportedly finds brown dwarfs about twice Jupiter’s mass in IC 348
A post describes the objects as too small to sustain the hydrogen fusion that powers normal stars, highlighting the uncertain boundary between planets and stars.
TLDR
A post says NASA’s James Webb Space Telescope identified extremely low-mass brown dwarfs in the star-forming region IC 348, including objects only about twice Jupiter’s mass. It describes them as unable to sustain the hydrogen fusion that powers normal stars and says the discovery offers new evidence about how very low-mass objects form from clouds of gas and dust.
