Japanese astronomers claim to have found 'earliest galaxy'

 

A team of Japanese astronomers using telescopes on Hawaii say they have seen the oldest galaxy, a discovery that is competing with other “earliest galaxy” claims.

The Japanese team calculates its galaxy was formed 12.91 billion light-years ago, 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 six trillion miles. Seeing distant galaxies is akin to looking back into time.

Richard Ellis of the California Institute of Technology, an influential expert in cosmology and galaxy formation, said the latest work as more convincing than some other galaxy discoveries.

He said the Japanese claim is more “watertight”, using methods that everyone can agree on. But he said it is not much of a change from a similar finding by the same team last year.

Still, “it's the most distant bullet-proof one that everybody believes”, Mr Ellis said.

In 2010, a French team using Nasa's Hubble Space Telescope claimed to have discovered a galaxy from 13.1 billion light-years ago and last year a California team using Hubble said they saw a galaxy from 13.2 billion light-years ago.

Both Hubble teams published findings in the journal Nature.

However, the two Hubble teams have yet to confirm their findings with other methods, said Mr Ellis.

Also, a team of Arizona State University astronomers this month claimed to have found a galaxy from 13 billion light-years away. They used a telescope in Chile.

Current theory holds that the universe was born of an explosion, called the Big Bang, about 13.7 billion years ago.

So astronomers using the most powerful telescopes available are peering deeper and deeper into that dawn of the universe.

The British government has announced plans to remove junk food from school lunches. From September 2006, food that is high in fat, sugar or salt will be banned from meals and removed from vending machines in schools across England. The move comes in response to a campaign by celebrity TV chef Jamie Oliver to improve school meals.
