ASTRONOMERS in Chile using a powerful telescope have observed what appears to be evidence of the existence of dark galaxies, the European Southern Observatory (ESO) says.

Dark galaxies are small, gas-rich galaxies from the early universe that are believed to be the building blocks of today’s bright, star-filled galaxies, said the ESO, an intergovernmental organisation supported by 15 countries.

“For the first time, dark galaxies – an early phase of galaxy formation, predicted by theory but unobserved until now – may have been spotted,” the observatory said in a statement on Wednesday.

“Using ESO’s Very Large Telescope, an international team thinks they have detected these elusive objects by observing them glowing as they are illuminated by a quasar,” the statement said.
