The galaxy pictured above at redshift 10.6 shines spectacularly 430 million years after the Big Bang. For the first time, the Hubble telescope observed this galaxy named GN-z11, and now this cosmic body looks like it is shining from the James Webb telescope. This luminosity is caused by the spiral of superheated gas and dust surrounding the supermassive black hole at the center of the galaxy.
According to James Webb’s other observations, the mentioned galaxy contains some of the first stars that formed in the universe. Evidence for this claim can be found in unusual chemical clumps of primordial helium gas around the edges of galaxies.
Early stars were mostly composed of hydrogen and helium, with small amounts of other chemical elements. This combination of features is exactly what James Webb probably saw in the GN-z11. If this discovery is confirmed, the long-time dream of astronomers to discover early stars will come true.
