Detecting the galaxy 'dark'

Astronomers have reported finding a type of galaxy previously predicted, which is a "dark" galaxy, with no stars but only full of gas.

The Kavli Foundation, based in California (USA), said the discovery of dark galaxies will help experts study their role in the evolution of the universe.

'The dark galaxy is made up of dark matter and gas, but for some reason, they are unable to form stars', according to Space.com quoted expert Martin Haehnelt of Kavli Institute of Cosmology at Dai. study Cambridge.

Some hypothetical models have predicted that dark galaxies are quite common in the early universe, when galaxies have difficulty in producing stars, in part because of the excess gas.

A group of international astronomers said some dark galaxies were found by observing the fluorescence emitted from their hydrogen gas, illuminated by ultraviolet light from a nearby hidden crystal.

Many people believe that dark galaxies play a role in building modern galaxies, contributing to the creation of large galaxies like today.
