Galaxies way ahead of their time
Sep 1, 2004
The first galaxies must have formed in a
cosmic twinkling of an eye, according to two
teams of astronomers that have been pushing
the world's largest telescopes to their
limits. Karl Glazebrook of Johns Hopkins
University in Baltimore and colleagues,
and, independently, Andrea Cimatti of the
Arcetri Observatory in Florence and coworkers
have found a number of large
galaxies that were already fully formed
when the universe was less than a quarter
of its present age (Nature 430 181 and 184). The new observations could force astrophysicists
to revise their cherished models of
galaxy formation.
