The discovery of a star that could be as old as the Universe supports the theory that the Milky Way "devoured" other smaller galaxies to its current size, according to a study led by the Harvard-Smithsonian Center for Astrophysics in Cambridge ( USA).
Scientists at the Brookhaven National Energy Laboratory in New York have recreated the hottest temperature ever since the Big Bang, 250,000 times hotter than that recorded at the center of the Sun and close to four trillion degrees. To achieve this they have used the Relativistic Heavy Ion Collider (RHIC) particle accelerator.
Although 13,000 million years ago the Universe was very different from the one we know today, there were already stars, as an international team of scientists, including Spaniards, has just demonstrated.
Virtually recreating the infancy of the Universe, astrophysicists at the SLAC National Accelerator Laboratory in the United States have concluded that the first stars emerged two by two.
