The first direct detection sheds light on dark galaxies


Most people think of the giant galaxies as islands of stars, gas and dust that block our universe with its light. Theory, however, predicts that there are other types of galaxies, devoid of stars, and consisting mainly of dense gas. These "dark" galaxies you can not see on the black background of the universe.

Now an international team of astronomers has found a few bright galaxies, watching the glow of hydrogen these galaxies, UV-induced nearby quasar HE0109-3518.

Astronomers first observed dark galaxies in the early universe

Astronomers has observed first dark galaxy, an early stage of galaxy formation, said the European Southern Observatory (ESO) from its headquarters in the German city of Garching, to the south.

Scientists used the long-range telescope (VLT, for its acronym in English) Cerro Paranal Observatory in Chile, which managed to detect these gas-rich galaxies that do not contain stars, noting its brightness when illuminated by light of a quasar.
