Thanks to the James Webb Space Telescope, astronomers racing to find some of the earliest galaxies ever glimpsed have now confirmed that a galaxy first detected last summer is in fact among the earliest ever found. The findings are in the journal Nature. Follow-up observations since first detection of Maisie’s galaxy have revealed that it is from 390 million years after the Big Bang. Although that’s not quite as early as the team led by University of Texas at Austin astronomer Steven Finkelstein first estimated last summer, it is nonetheless one of the four earliest confirmed galaxies observed.
