NASA unveiled the first full colored image from the James Webb telescope. It shows the galaxy cluster SMACS 0723 (SMACS J0723.3-7327) which acts as a gravitational lens and magnifies light coming from behind.
Astronomers identified the new substellar object in a JWST image of galaxy cluster Abell 2744. The brown dwarf GLASS-JWST-BD1 is a single object more than 2 thousand light years away. It has about 30 jupiter masses (0.03 solar mass).
