Mexican astrophysicist Carlos Frenk Mora has identified some of the first galaxies in our universe together with a team of researchers, said the National Autonomous University of Mexico on Saturday.
The newly-identified galaxies are: Segue-1, Bootes I, Tucana II and Ursa Mayor I. All were formed more than 13 billion years ago.
The discovery backs a current evolutionary model of the universe, called the Lambda Cold Dark Matter Theory, which maintains that the elementary particles that make up dark matter drive cosmic evolution.
The most weak galaxies near the Milk Way were considered unworthy subject for study by scientists a decade ago, but new researches have revealed treasures for us to learn about the primitive universe, said Mora.
The Mexican scientist is one of the world's best known astronomers for his theories on dark matter and its role in the formation of galaxies.
