Farthest known galaxy in the universe found

PARIS: Astronomers using a complex system of super telescopes have caught a glimpse of what is likely the most distant, and thus oldest, galaxy ever seen — some 13.3 billion light years from Earth.
The star cluster was observed in its infancy — as it looked when the Universe was just three percent of its present age, NASA and the European Space Agency announced.
“We see the newly discovered galaxy, named MACS0647-JD, as it was 420 million years after the Big Bang” that created the Universe 13.7 billion years ago, a statement said.
“Its light has traveled 13.3 billion years to reach Earth.”
The astronomers, grouped under the joint American-European CLASH project, use the orbiting Hubble and Spitzer telescopes as well as employing massive galaxy clusters as cosmic magnifiers to find distant galaxies.
The process, known as gravitational lensing, allows astronomers to see galaxies that emit light with a brightness weaker than that of a candle on the Moon, thus undetectable directly by telescopes on Earth. The newly discovered cluster is so small, less than 600 light years across, that scientists believe it may still be in the first stages of galaxy formation.
Our own Milky Way is 150,000 light years across.
“The estimated mass of this baby galaxy is roughly equal to 100 million or a billion suns, or 0.1 to 1.0 percent of our Milky Way's stars,” the statement said.
In September, the CLASH scientists said they had spotted the Universe's oldest and furthest galaxy, using the same technique — the previous record-holding 13.2 billion light years away.
With gravitational lensing, theorized by Albert Einstein himself, astronomers use younger galaxies that lie closer to Earth to magnify older ones lurking in the distance by bending the light they emit.

Saudi Society for Medical Genetics approves 12 recommendations to combat diseases

  • More than 130 pediatricians, geneticists, genetic researchers, laboratory technicians, nutritionists attended the conference from across the kingdom.
  • The conference is an opportunity for medical professionals and workers in the region to keep up-to-date with the most important developments.

RIYADH: Saudi Society of Medical Genetics (SSMG) concluded its conference in Riyadh by approving 12 recommendations aimed at fighting genetic diseases, the Saudi Press Agency reported Monday.

More than 130 pediatricians, geneticists, genetic researchers, laboratory technicians, nutritionists attended the conference from across the kingdom.

President of the Association, Dr. Zuhair Rahbini, praised the success of the conference, saying it comes in line with the efforts of Saudi government to support all that serves the citizen and supports social health efforts and increases awareness levels to confront genetic diseases.

Dr. Saleh bin Mohammed Al-Ghamdi, Chairman of the Genetic Research Committee, said the conference has come out with 12 recommendations related to many topics covered by the conference, which include genes, the human genome and the relationship of genes to other environmental factors.

The conference is an opportunity for medical professionals and workers in the country to keep up-to-date with the most important developments, such as early screening for metabolic diseases in newborns, their clinical treatment and new medical treatments across the spectra of metabolic diseases.
