With a strategy of obtaining deep JWST imaging and following up interesting candidates with NIRSpec spectroscopy, the JADES survey has: broken the highest redshift spectroscopically confirmed record (twice); found possible evidence for the earliest black hole at z~10.6, though other explanations exist; found direct evidence for the stochasticity of star formation in early galaxies with the highest redshift ‘mini-quenched’ galaxy, and much more besides. I will summarise key results from JADES survey focusing on Chemical evolution and abundances of the earliest galaxies.
