James Webb Space Telescope captures widest stellar field and finds light brown dwarfs

The James Webb Space Telescope has captured its widest stellar field to date, revealing the lightest brown dwarfs ever observed. Located in the IC 348 star-forming region within the Perseus constellation, the infrared image shows hundreds of young stars, gas jets, and dust clouds approximately 1,000 light-years from Earth.

Astronomers confirmed nine new sub-stellar objects that exist on the threshold between planets and stars. The smallest of these has a mass only about twice that of Jupiter. These brown dwarfs are significant because they serve as records of the conditions within gas clouds before fragmentation.

In a separate development, NASA has selected the Probe far-Infrared Mission for Astrophysics (PRIMA) to advance to the next phase of development. Developed by the Jet Propulsion Laboratory (JPL), PRIMA is designed to observe the far-infrared spectrum, a region currently inaccessible to the James Webb Space Telescope. The mission aims to study planet formation, galaxy evolution, and black holes.
