Maisie's Galaxy

Maisie's Galaxy is a distant galaxy located in constellation Boötes with a redshift of z=11.4 dating from approximately 390 million years after the Big Bang.

Background

Discovered in 2022 using the James Webb Space Telescope in the CEERS field, Maisie's Galaxy has high star formation rates. It was named after the nine-year-old daughter of the person who discovered it, Steve Finkelstein, an astronomer at the University of Texas at Austin.
In February 2023, the CEERS teams followed up their high-redshift candidates with observatory's NIRSpec instrument to measure precise, spectroscopic redshifts. One candidate has been confirmed to be at redshift 11.4, while the second candidate was discovered to actually be at a lower redshift of 4.9.
