JADES-GS-z14-0 was discovered last week, in the Fornax constellation. This galaxy, just 300 million years after the Big Bang, is larger and brighter than expected, spanning 1,600 light-years and being several hundred million times the mass of the Sun. Its redshift breaks the previous distance records but, more surprising, it contains dust and oxygen, indicating multiple generations of massive stars. This discovery does not match the types predicted by theoretical existing models! This "young" galaxy (compared to 13.8B years since the Big Bang) should not be so large, so bright... and should not contain oxygen at this stage. Another crazy finding, thanks to Webb Telescope. Exciting times for astronomy, cosmology and cosmogony! #Astronomy #JWST #JADES #Space https://lnkd.in/eGBxukVn
