‘BABY MILKY WAY’ DISCOVERED 12 BILLION LIGHT YEARS AWAY
Astronomers said a golden halo glinting 12 billion light-years away is the farthest galaxy resembling our milky way yet spotted.
The galaxy, called SPT0418-47, is so far away that it took billions of years for its light to reach Earth, and so our image of it is from deep in the past, said the European Southern Observatory (ESO), which was involved in the discovery.
The ESO said the “baby” SPT0418-47 was picked up by the powerful Alma radio telescope in Chile using gravitational lensing. A nearby galaxy acts as a powerful magnifying glass.
It has features similar to our Milky Way—a rotating disc and a bulge, which is the high density of stars packed tightly around the galactic center.
