ASTROPHYSICS:
Galaxies Seen at the Universe's Dawn
Govert Schilling
Astronomers analyzing data from the Hubble Space Telescope may have shattered previous records for the most distant stars and galaxies. The farthest galaxy spotted until now has a redshift of 5.64, meaning that the expansion of the universe has stretched its light by a factor of 6.64. The new galaxies could have redshifts of 10, meaning they are seen when the universe was only 9% of its current size and probably just a few hundred million years old.
