Unexpected brightness of JADES-GS-z14-0 means telescope could capture images of galaxies even further away
The newly observed galaxy is much brighter than expected, suggesting that the first generation of stars were either more luminous or formed much more rapidly than conventional cosmological theories have predicted. Due to the expansion of the universe, the light from distant galaxies stretches to longer wavelengths as it travels, an effect known as redshift. Dr Stefano Carniani, of the Scuola Normale Superiore in Pisa, the lead author on the discovery paper, said: “JADES-GS-z14-0 now becomes the archetype of this phenomenon.
