'Oldest Galaxy' Discovered Using Hawaii Telescope
from the Guardian (UK)
A team of Japanese astronomers using telescopes on Hawaii say they have seen the oldest galaxy yet discovered. The team calculates that the galaxy is 12.91bn light years away, and their research will be published in the Astrophysical Journal. The scientists with the National Astronomical Observatory of Japan used the Subaru and Keck telescopes on the summit of Mauna Kea.
A light year is the distance that light travels in a year, about 6 trillion miles (9.66 trillion kilometres). Seeing distant galaxies is in effect looking back in time.
Richard Ellis of the California Institute of Technology, an influential expert in cosmology and galaxy formation, said the latest work was more convincing than some other claims of early galaxies. He said the Japanese claim was more "watertight," using methods that everyone can agree on. But he said it was not much of a change from a similar finding by the same team last year.
