Astronomers using the NASA/ESA / CSA James Webb Space Telescope have discovered an active supermassive black hole in CEERS 1019, a galaxy that existed...

Montage of Webb images showing six example barred galaxies, two of which represent the highest lookback times quantitatively identified and characterized to date. The labels in the top left of each figure show the lookback time of each galaxy, ranging from 8.4 to 11 billion years ago (Gyr), when the Universe was a mere 40% to 20% of its present age.

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have spotted early galaxies with stellar bars — elongated features of stars stretching...

This image from Webb’s Near Infrared Camera (NIRCam) shows the Maisie’s galaxy, one of the earliest galaxies ever observed; if its estimated redshift of 14.3 is confirmed with future observations, that would mean we’re seeing it as it was just 290 million years after the Big Bang.
